CodeBase（五）工具类积累

一、CustomDialog

(1)xml举例

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="match_parent" android:layout_height="match_parent"android:orientation="vertical"xmlns:android="http://schemas.android.com/apk/res/android"><Viewandroid:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="3"></View><LinearLayoutandroid:layout_width="fill_parent"android:layout_height="0dp"android:layout_gravity="center"android:layout_weight="2"android:background="#ffffff"android:orientation="vertical"><TextViewandroid:id="@+id/title"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="4"android:background="#ff7200"android:gravity="center"android:text="@string/tv_title"android:textColor="#ffffff"android:textSize="25sp" /><LinearLayoutandroid:layout_width="match_parent"android:layout_height="0dp"android:layout_gravity="bottom"android:layout_weight="2"android:background="#ffffff"android:gravity="center"android:orientation="horizontal"><TextViewandroid:id="@+id/tv_cancel"android:layout_width="0dp"android:layout_height="match_parent"android:layout_weight="1"android:background="@drawable/rectangle_shape"android:gravity="center"android:text="@string/tv_cancel"android:textColor="#b8b8b8"android:textSize="25sp" /><TextViewandroid:id="@+id/tv_confirm"android:layout_width="0dp"android:layout_height="match_parent"android:layout_weight="1"android:background="@drawable/rectangle_shape"android:gravity="center"android:text="@string/tv_submit"android:textColor="#ff9138"android:textSize="25sp" /></LinearLayout></LinearLayout><Viewandroid:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="2"></View>
</LinearLayout>

（2）utils

public class CustomDialog extends Dialog {public CustomDialog(Context context) {super(context);}public CustomDialog(Context context, int state) {super(context, state);}public static class Builder {private Context context;private View contentView;private int state;private   View layout = null;private DialogInterface.OnClickListener cancelButtonClickListener;private DialogInterface.OnClickListener confirmButtonClickListener;public Builder(Context context, int state) {this.context = context;this.state = state;}public Builder setContentView(View v) {this.contentView = v;return this;}public Builder setCancelButton(DialogInterface.OnClickListener listener) {this.cancelButtonClickListener = listener;return this;}public Builder setConfirmButton(DialogInterface.OnClickListener listener) {this.confirmButtonClickListener = listener;return this;}public CustomDialog create() {LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);// instantiate the dialog with the custom Themefinal CustomDialog dialog = new CustomDialog(context, R.style.Dialog);switch (state){case 0:layout = inflater.inflate(R.layout.layout_anser_dialog, null);break;case 1:layout = inflater.inflate(R.layout.layout_return_dialog1, null);break;case 2:layout = inflater.inflate(R.layout.layout_return_dialog2, null);break;case 3:layout = inflater.inflate(R.layout.layout_return_dialog3, null);break;case 4:layout = inflater.inflate(R.layout.layout_return_dialog4, null);break;default:break;}dialog.addContentView(layout, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));if (cancelButtonClickListener != null) {((TextView) layout.findViewById(R.id.tv_cancel)).setOnClickListener(new View.OnClickListener() {public void onClick(View v) {cancelButtonClickListener.onClick(dialog,DialogInterface.BUTTON_POSITIVE);}});}if (confirmButtonClickListener != null) {((TextView) layout.findViewById(R.id.tv_confirm)).setOnClickListener(new View.OnClickListener() {public void onClick(View v) {confirmButtonClickListener.onClick(dialog,DialogInterface.BUTTON_NEGATIVE);}});}dialog.setContentView(layout);return dialog;}}}

（3）引用

 @Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) {if (keyCode==KeyEvent.KEYCODE_BACK){CustomDialog.Builder builder = new CustomDialog.Builder(BreakActivity.this,1);builder.setCancelButton( new android.content.DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {dialog.dismiss();}});builder.setConfirmButton(new android.content.DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {dialog.dismiss();finish();}});builder.create().show();return true;}return super.onKeyDown(keyCode, event);}

二、GetdataUtil本地文件读取

public class GetdataUtil  {private  static Context context;public GetdataUtil(Context context) {this.context = context;}public static List<String> GetrobotName(){List<String> stringList = new ArrayList<>();InputStream is = context.getClass().getClassLoader().getResourceAsStream("assets/"+"robotName");InputStreamReader streamReader = new InputStreamReader(is);BufferedReader reader = null;StringBuffer sbf = new StringBuffer();try {reader  = new BufferedReader(streamReader);String tempStr;while ((tempStr = reader.readLine()) != null) {stringList.add(tempStr);sbf.append(tempStr);}reader.close();} catch (IOException e) {e.printStackTrace();} finally {if (reader != null) {try {reader.close();} catch (IOException e1) {e1.printStackTrace();}}}return stringList;}
}

三、RegisterPopWin


public class RegisterPopWin extends PopupWindow {private Context mContext;private View view;private EditText et_name, et_phone, et_pass;private Button bt_login,bt_test,bt_login2,bt_test2;private TextView tv_iknow;private ImageView imageView;public RegisterPopWin(Context mContext, View.OnClickListener itemsOnClick,int i) {this.view = LayoutInflater.from(mContext).inflate(R.layout.lay_forget, null);bt_login2 = view.findViewById(R.id.bt_login2);bt_test2 = view.findViewById(R.id.bt_test2);// 取消按钮
//        btn_cancel.setOnClickListener(new View.OnClickListener() {
//
//            public void onClick(View v) {
//                // 销毁弹出框
//                dismiss();
//            }
//        });// 设置按钮监听bt_test2.setOnClickListener(itemsOnClick);bt_login2.setOnClickListener(itemsOnClick);// 设置外部可点击this.setOutsideTouchable(true);// mMenuView添加OnTouchListener监听判断获取触屏位置如果在选择框外面则销毁弹出框this.view.setOnTouchListener(new View.OnTouchListener() {public boolean onTouch(View v, MotionEvent event) {int height = view.findViewById(R.id.pop_layout).getTop();int y = (int) event.getY();if (event.getAction() == MotionEvent.ACTION_UP) {if (y < height) {dismiss();}}return true;}});/* 设置弹出窗口特征 */// 设置视图this.setContentView(this.view);// 设置弹出窗体的宽和高this.setHeight(RelativeLayout.LayoutParams.MATCH_PARENT);this.setWidth(RelativeLayout.LayoutParams.MATCH_PARENT);// 设置弹出窗体可点击this.setFocusable(true);// 实例化一个ColorDrawable颜色为半透明//  ColorDrawable dw = new ColorDrawable(0xb0000000);// 设置弹出窗体的背景// this.setBackgroundDrawable(dw);// 设置弹出窗体显示时的动画，从底部向上弹出this.setAnimationStyle(R.style.popwin_register);}}public View getView() {return view;}public void setView(View view) {this.view = view;}
}

四、StatusBarUtils

 /*** 说明：* 1. SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN：Activity全屏显示，但状态栏不会被隐藏覆盖。* 2. SYSTEM_UI_FLAG_LIGHT_STATUS_BAR：设置状态栏图标为黑色或者白色* 3.
