效果演示

随手做的一个小玩意，还有很多功能没有完善，倘有疏漏，万望海涵。

实现功能总览

实现了登录、注册、忘记密码、成绩查询、考勤情况、课表查看、提交作业、课程打卡等。

代码

登录与忘记密码界面
登录与忘记密码界面采用的是TabLayout+ViewPager+PagerAdapter实现的
一、添加布局文件

 View View_HomePager = LayoutInflater.from( Student.this ).inflate( R.layout.homeppage_item,null,false );View View_Data = LayoutInflater.from( Student.this ).inflate( R.layout.data_item,null,false );View View_Course = LayoutInflater.from( Student.this ).inflate( R.layout.course_item,null,false );View View_My = LayoutInflater.from( Student.this ).inflate( R.layout.my_item,null,false );

private List<View> Views = new ArrayList<>(  );

 Views.add( View_HomePager );Views.add( View_Data );Views.add( View_Course );Views.add( View_My );

二、添加标题文字

private List<String> Titles = new ArrayList<>(  );
Titles.add( "首页" );
Titles.add( "数据" );
Titles.add( "课程" );
Titles.add( "我的" );

三、绑定适配器

/*PagerAdapter 适配器代码如下*/
public class ViewPagerAdapter extends PagerAdapter {private List<View> Views;private List<String> Titles;public ViewPagerAdapter(List<View> Views,List<String> Titles){this.Views = Views;this.Titles = Titles;}@Overridepublic int getCount() {return Views.size();}@Overridepublic boolean isViewFromObject(@NonNull View view, @NonNull Object object) {return view == object;}@NonNull@Overridepublic Object instantiateItem(@NonNull ViewGroup container, int position) {container.addView( Views.get( position ) );return Views.get( position );}@Overridepublic void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {container.removeView( Views.get( position ) );}@Nullable@Overridepublic CharSequence getPageTitle(int position) {return Titles.get( position );}
}

 ViewPagerAdapter adapter = new ViewPagerAdapter( Views,Titles );for (String title : Titles){Title.addTab( Title.newTab().setText( title ) );}Title.setupWithViewPager( viewPager );viewPager.setAdapter( adapter );

注册界面
一、创建两个Drawable文件
其一

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<solid android:color="#63B8FF"/><size android:width="20dp" android:height="20dp"/>
</shape>

其二

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval"><solid android:color="#ffffff"/><size android:height="20dp" android:width="20dp"/><stroke android:width="1dp" android:color="#EAEAEA"/>
</shape>

二、将其添加数组内

private final int[] Identity = {R.drawable.press_oval_textview,R.drawable.notpress_oval_textview};

三、动态变化背景

 private void SelectStudent(){mIdentity_Student.setBackgroundResource( Identity[0] );mIdentity_Teacher.setBackgroundResource( Identity[1] );}private void SelectTeacher(){mIdentity_Student.setBackgroundResource( Identity[1] );mIdentity_Teacher.setBackgroundResource( Identity[0] );}

考勤界面
主要是通过绘制一个圆，圆环、内圆、文字分别使用不同的背景颜色，并将修改背景颜色的接口暴露出来。
一、CircleProgressBar代码如下

public class CircleProgressBar extends View {// 画实心圆的画笔private Paint mCirclePaint;// 画圆环的画笔private Paint mRingPaint;// 画圆环的画笔背景色private Paint mRingPaintBg;// 画字体的画笔private Paint mTextPaint;// 圆形颜色private int mCircleColor;// 圆环颜色private int mRingColor;// 圆环背景颜色private int mRingBgColor;// 半径private float mRadius;// 圆环半径private float mRingRadius;// 圆环宽度private float mStrokeWidth;// 圆心x坐标private int mXCenter;// 圆心y坐标private int mYCenter;// 字的长度private float mTxtWidth;// 字的高度private float mTxtHeight;// 总进度private int mTotalProgress = 100;// 当前进度private double mProgress;public CircleProgressBar(Context context) {super( context );}public CircleProgressBar(Context context, @Nullable AttributeSet attrs) {super( context, attrs );initAttrs(context,attrs);initVariable();}public CircleProgressBar(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {super( context, attrs, defStyleAttr );}private void initAttrs(Context context, AttributeSet attrs) {TypedArray typeArray = context.getTheme().obtainStyledAttributes(attrs,R.styleable.TasksCompletedView, 0, 0);mRadius = typeArray.getDimension(R.styleable.TasksCompletedView_radius, 80);mStrokeWidth = typeArray.getDimension(R.styleable.TasksCompletedView_strokeWidth, 10);mCircleColor = typeArray.getColor(R.styleable.TasksCompletedView_circleColor, 0xFFFFFFFF);mRingColor = typeArray.getColor(R.styleable.TasksCompletedView_ringColor, 0xFFFFFFFF);mRingBgColor = typeArray.getColor(R.styleable.TasksCompletedView_ringBgColor, 0xFFFFFFFF);mRingRadius = mRadius + mStrokeWidth / 2;}private void initVariable() {//内圆mCirclePaint = new Paint();mCirclePaint.setAntiAlias(true);mCirclePaint.setColor(mCircleColor);mCirclePaint.setStyle(Paint.Style.FILL);//外圆弧背景mRingPaintBg = new Paint();mRingPaintBg.setAntiAlias(true);mRingPaintBg.setColor(mRingBgColor);mRingPaintBg.setStyle(Paint.Style.STROKE);mRingPaintBg.setStrokeWidth(mStrokeWidth);//外圆弧mRingPaint = new Paint();mRingPaint.setAntiAlias(true);mRingPaint.setColor(mRingColor);mRingPaint.setStyle(Paint.Style.STROKE);mRingPaint.setStrokeWidth(mStrokeWidth);//mRingPaint.setStrokeCap(Paint.Cap.ROUND);//设置线冒样式，有圆 有方//中间字mTextPaint = new Paint();mTextPaint.setAntiAlias(true);mTextPaint.setStyle(Paint.Style.FILL);mTextPaint.setColor(mRingColor);mTextPaint.setTextSize(mRadius / 2);Paint.FontMetrics fm = mTextPaint.getFontMetrics();mTxtHeight = (int) Math.ceil(fm.descent - fm.ascent);}@Overrideprotected void onDraw(Canvas canvas) {super.onDraw( canvas );mXCenter = getWidth() / 2;mYCenter = getHeight() / 2;//内圆canvas.drawCircle( mXCenter, mYCenter, mRadius, mCirclePaint );//外圆弧背景RectF oval1 = new RectF();oval1.left = (mXCenter - mRingRadius);oval1.top = (mYCenter - mRingRadius);oval1.right = mRingRadius * 2 + (mXCenter - mRingRadius);oval1.bottom = mRingRadius * 2 + (mYCenter - mRingRadius);canvas.drawArc( oval1, 0, 360, false, mRingPaintBg ); //圆弧所在的椭圆对象、圆弧的起始角度、圆弧的角度、是否显示半径连线//外圆弧if (mProgress > 0) {RectF oval = new RectF();oval.left = (mXCenter - mRingRadius);oval.top = (mYCenter - mRingRadius);oval.right = mRingRadius * 2 + (mXCenter - mRingRadius);oval.bottom = mRingRadius * 2 + (mYCenter - mRingRadius);canvas.drawArc( oval, -90, ((float) mProgress / mTotalProgress) * 360, false, mRingPaint ); ////字体String txt = mProgress + "%";mTxtWidth = mTextPaint.measureText( txt, 0, txt.length() );canvas.drawText( txt, mXCenter - mTxtWidth / 2, mYCenter + mTxtHeight / 4, mTextPaint );}}//设置进度public void setProgress(double progress) {mProgress = progress;postInvalidate();//重绘}public void setCircleColor(int Color){mRingPaint.setColor( Color );postInvalidate();//重绘}
}

签到界面
签到界面就倒计时和位置签到
一、倒计时
采用的是Thread+Handler
在子线程内总共发生两种标志至Handler内，0x00表示倒计时未完成，0x01表示倒计时完成。

private void CountDown(){new Thread(  ){@Overridepublic void run() {super.run();for (int j = 14; j >= 0 ; j--) {for (int i = 59; i >= 0; i--) {Message message = handler.obtainMessage();message.what = 0x00;message.arg1 = i;message.arg2 = j;handler.sendMessage( message );try {Thread.sleep( 1000 );} catch (InterruptedException e) {e.printStackTrace();}}}Message message = handler.obtainMessage(  );message.what = 0x01;handler.sendMessage( message );}}.start();}

 final Handler handler = new Handler(  ){@Overridepublic void handleMessage(@NonNull Message msg) {super.handleMessage( msg );switch (msg.what){case 0x00:if (msg.arg2 >= 10){SignInMinutes.setText( msg.arg2+":" );}else if (msg.arg2 < 10 && msg.arg2 > 0){SignInMinutes.setText( "0"+msg.arg2+":" );}else {SignInMinutes.setText( "00"+":" );}if (msg.arg1 >= 10){SignInSeconds.setText( msg.arg1+"" );}else if (msg.arg1 < 10 && msg.arg1 > 0){SignInSeconds.setText( "0"+msg.arg1 );}else {SignInSeconds.setText( "00" );}break;case 0x01:SignInSeconds.setText( "00" );SignInMinutes.setText( "00:" );break;}}};

一、位置签到
位置签到采用的是百度地图SDK


public class LocationCheckIn extends AppCompatActivity {private MapView BaiDuMapView;private TextView CurrentPosition,mLatitude,mLongitude,CurrentDate,SignInPosition;private Button SubmitMessage,SuccessSignIn;private ImageView LocationSignIn_Exit;private  View view = null;private PopupWindow mPopupWindow;private LocationClient client;private BaiduMap mBaiduMap;private double Latitude = 0;private double Longitude = 0;private boolean isFirstLocate = true;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate( savedInstanceState );if (Build.VERSION.SDK_INT >= 21) {View decorView = getWindow().getDecorView();decorView.setSystemUiVisibility( View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE );getWindow().setStatusBarColor( Color.TRANSPARENT );}SDKInitializer.initialize( getApplicationContext() );client = new LocationClient( getApplicationContext() );//获取全局Contextclient.registerLocationListener( new MyBaiDuMap() );//注册一个定位监听器，获取位置信息，回调此定位监听器setContentView( R.layout.activity_location_check_in );InitView();InitBaiDuMap();InitPermission();InitPopWindows();Listener();}private void InitView(){BaiDuMapView = findViewById( R.id.BaiDu_MapView );CurrentPosition = findViewById( R.id.CurrentPosition );SubmitMessage = findViewById( R.id.SubmitMessage );mLatitude = findViewById( R.id.Latitude );mLongitude = findViewById( R.id.Longitude );LocationSignIn_Exit = findViewById( R.id.LocationSignIn_Exit );}private void InitPopWindows(){view = LayoutInflater.from( LocationCheckIn.this ).inflate( R.layout.signin_success ,null,false);CurrentDate = view.findViewById( R.id.CurrentDate );SignInPosition = view.findViewById( R.id.SignInPosition );SuccessSignIn = view.findViewById( R.id.Success);mPopupWindow = new PopupWindow( view, ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT );mPopupWindow.setFocusable( true ); //获取焦点mPopupWindow.setBackgroundDrawable( new BitmapDrawable() );mPopupWindow.setOutsideTouchable( true ); //点击外面地方，取消mPopupWindow.setTouchable( true ); //允许点击mPopupWindow.setAnimationStyle( R.style.MyPopupWindow ); //设置动画Calendar calendar = Calendar.getInstance();int Hour = calendar.get( Calendar.HOUR_OF_DAY );int Minute = calendar.get( Calendar.MINUTE );String sHour,sMinute;if (Hour < 10){sHour = "0"+Hour;}else {sHour = ""+Hour;}if (Minute < 10){sMinute = "0"+Minute;}else {sMinute = ""+Minute;}CurrentDate.setText( sHour+":"+sMinute );//SignInPosition.setText( Position+"000");SuccessSignIn.setOnClickListener( new View.OnClickListener() {@Overridepublic void onClick(View v) {mPopupWindow.dismiss();}} );}private void ShowPopWindows(){mPopupWindow.showAtLocation( view, Gravity.CENTER,0,0 );}private void InitBaiDuMap(){/*百度地图初始化*/mBaiduMap = BaiDuMapView.getMap();//获取实例，可以对地图进行一系列操作，比如：缩放范围，移动地图mBaiduMap.setMyLocationEnabled(true);//允许当前设备显示在地图上}private void navigateTo(BDLocation location){if (isFirstLocate){LatLng lng = new LatLng(location.getLatitude(),location.getLongitude());//指定经纬度MapStatusUpdate update = MapStatusUpdateFactory.newLatLng(lng);mBaiduMap.animateMapStatus(update);update = MapStatusUpdateFactory.zoomTo(16f);//百度地图缩放级别限定在3-19mBaiduMap.animateMapStatus(update);isFirstLocate = false;}MyLocationData.Builder builder = new MyLocationData.Builder();builder.latitude(location.getLatitude());//纬度builder.longitude(location.getLongitude());//经度MyLocationData locationData = builder.build();mBaiduMap.setMyLocationData(locationData);}private void InitPermission(){List<String> PermissionList = new ArrayList<>();//判断权限是否授权if (ContextCompat.checkSelfPermission( LocationCheckIn.this, Manifest.permission.ACCESS_FINE_LOCATION ) != PackageManager.PERMISSION_GRANTED) {PermissionList.add( Manifest.permission.ACCESS_FINE_LOCATION );}if (ContextCompat.checkSelfPermission( LocationCheckIn.this, Manifest.permission.READ_PHONE_STATE ) != PackageManager.PERMISSION_GRANTED) {PermissionList.add( Manifest.permission.READ_PHONE_STATE );}if (ContextCompat.checkSelfPermission( LocationCheckIn.this, Manifest.permission.WRITE_EXTERNAL_STORAGE ) != PackageManager.PERMISSION_GRANTED) {PermissionList.add( Manifest.permission.WRITE_EXTERNAL_STORAGE );}if (!PermissionList.isEmpty()) {String[] Permissions = PermissionList.toArray( new String[PermissionList.size()] );//转化为数组ActivityCompat.requestPermissions( LocationCheckIn.this, Permissions, 1 );//一次性申请权限} else {/*****************如果权限都已经声明，开始配置参数*****************/requestLocation();}}//执行private void requestLocation(){initLocation();client.start();}/*******************初始化百度地图各种参数*******************/public  void initLocation() {LocationClientOption option = new LocationClientOption();option.setLocationMode(LocationClientOption.LocationMode.Hight_Accuracy);/**可选，设置定位模式，默认高精度LocationMode.Hight_Accuracy：高精度；* LocationMode.

}

成绩查询界面
采用的是MD的CardStackView，需要实现一个Adapter适配器，此适配器与RecyclerView适配器构建类似
一、创建StackAdapter 适配器

package com.franzliszt.Student.QueryScore;
public class StackAdapter extends com.loopeer.cardstack.StackAdapter<Integer> {public StackAdapter(Context context) {super(context);}@Overridepublic void bindView(Integer data, int position, CardStackView.ViewHolder holder) {if (holder instanceof ColorItemLargeHeaderViewHolder) {ColorItemLargeHeaderViewHolder h = (ColorItemLargeHeaderViewHolder) holder;h.onBind(data, position);}if (holder instanceof ColorItemWithNoHeaderViewHolder) {ColorItemWithNoHeaderViewHolder h = (ColorItemWithNoHeaderViewHolder) holder;h.onBind(data, position);}if (holder instanceof ColorItemViewHolder) {ColorItemViewHolder h = (ColorItemViewHolder) holder;h.onBind(data, position);}}@Overrideprotected CardStackView.ViewHolder onCreateView(ViewGroup parent, int viewType) {View view;switch (viewType) {case R.layout.list_card_item_larger_header:view = getLayoutInflater().inflate(R.layout.list_card_item_larger_header, parent, false);return new ColorItemLargeHeaderViewHolder(view);case R.layout.list_card_item_with_no_header:view = getLayoutInflater().inflate(R.layout.list_card_item_with_no_header, parent, false);return new ColorItemWithNoHeaderViewHolder(view);case R.layout.other_item:view = getLayoutInflater().inflate(R.layout.other_item, parent, false);return new ColorItemViewHolder(view);case R.layout.other_item_thank:view = getLayoutInflater().inflate(R.layout.other_item_thank, parent, false);return new ColorItemViewHolder(view);case R.layout.other_item_note_1:view = getLayoutInflater().inflate(R.layout.other_item_note_1, parent, false);return new ColorItemViewHolder(view);case R.layout.other_item_note_2:view = getLayoutInflater().inflate(R.layout.other_item_note_2, parent, false);return new ColorItemViewHolder(view);default:view = getLayoutInflater().inflate(R.layout.first_semester, parent, false);return new ColorItemViewHolder(view);}}@Overridepublic int getItemViewType(int position) {if (position == 6 ){//TODO TEST LARGER ITEMreturn R.layout.other_item;} else if (position == 7){return R.layout.other_item_thank;}else if (position == 8){return R.layout.other_item_note_1;}else if (position == 9){return R.layout.other_item_note_2;} else {return R.layout.first_semester;}}static class ColorItemViewHolder extends CardStackView.ViewHolder {View mLayout;View mContainerContent;TextView mTextTitle;TextView ClassName1,ClassStatus1,ClassMethod1,ClassFlag1,Credit1,GradePoint1;TextView ClassName2,ClassStatus2,ClassMethod2,ClassFlag2,Credit2,GradePoint2;TextView ClassName3,ClassStatus3,ClassMethod3,ClassFlag3,Credit3,GradePoint3;TextView ClassName4,ClassStatus4,ClassMethod4,ClassFlag4,Credit4,GradePoint4;TextView TitleContent,MoreInfo;public ColorItemViewHolder(View view) {super(view);mLayout = view.findViewById(R.id.frame_list_card_item);mContainerContent = view.findViewById(R.id.container_list_content);mTextTitle =  view.findViewById(R.id.text_list_card_title);TitleContent = view.findViewById( R.id.TitleContent );MoreInfo = view.findViewById( R.id.MoreInfo );ClassName1 =  view.findViewById(R.id.ClassName1);ClassStatus1 =  view.findViewById(R.id.ClassStatus1);ClassMethod1 =  view.findViewById(R.id.ClassMethod1);ClassFlag1 =  view.findViewById(R.id.ClassFlag1);Credit1 =  view.findViewById(R.id.Credit1);GradePoint1=  view.findViewById(R.id.GradePoint1);ClassName2 =  view.findViewById(R.id.ClassName2);ClassStatus2 =  view.findViewById(R.id.ClassStatus2);ClassMethod2 =  view.findViewById(R.id.ClassMethod2);ClassFlag2 =  view.findViewById(R.id.ClassFlag2);Credit2 =  view.findViewById(R.id.Credit2);GradePoint2=  view.findViewById(R.id.GradePoint2);ClassName3 =  view.findViewById(R.id.ClassName3);ClassStatus3 =  view.findViewById(R.id.ClassStatus3);ClassMethod3 =  view.findViewById(R.id.ClassMethod3);ClassFlag3 =  view.findViewById(R.id.ClassFlag3);Credit3 =  view.findViewById(R.id.Credit3);GradePoint3=  view.findViewById(R.id.GradePoint3);ClassName4 =  view.findViewById(R.id.ClassName4);ClassStatus4 =  view.findViewById(R.id.ClassStatus4);ClassMethod4 =  view.findViewById(R.id.ClassMethod4);ClassFlag4 =  view.findViewById(R.id.ClassFlag4);Credit4 =  view.findViewById(R.id.Credit4);GradePoint4 = view.findViewById(R.id.GradePoint4);}@Overridepublic void onItemExpand(boolean b) {mContainerContent.setVisibility(b ?

二、绑定适配器

 QueryScoreCardStackView.setItemExpendListener( this );adapter = new StackAdapter( this );QueryScoreCardStackView.setAdapter( adapter );

三、为每一个子项添加背景色

    public static Integer[] COLOR_DATAS = new Integer[]{R.color.color_1,R.color.color_2,R.color.color_3,R.color.color_4,R.color.color_5,R.color.color_6,R.color.color_7,R.color.color_8,R.color.color_9,R.color.color_10,};

 new Handler(  ).postDelayed( new Runnable() {@Overridepublic void run() {adapter.updateData( Arrays.asList( COLOR_DATAS ) );}} ,200);
