智能农业的开发步骤
首先需要导一下数据包。
compile 'com.makeramen:roundedimageview:2.2.1'--让图片变成圆形的效果compile 'com.loopj.android:android-async-http:1.4.9'compile 'com.google.code.gson:gson:2.8.2'implementation 'com.squareup.okhttp3:okhttp:3.10.0'第一步
我们先做三个页面的滑动，用fragment和viewPager来实现。先建一个三个fragment。把HomePageFragment作为首页。fragment_help布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context="android.coolweather2.com.agriculturedemo.fragment.HelpFragment"><LinearLayout

fragment_set布局：

fragment_home_page布局：在这里面需要用到ScrollView来进行页面的滚动。我们可以把homepage里面的东西单独拿出来，放在各自的XML文件里面。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context="android.coolweather2.com.agriculturedemo.fragment.HomePageFragment"><TextView

android:layout_width="match_parent"android:layout_height="match_parent"android:layout_above="@+id/main_bottom_lin"android:layout_alignParentLeft="true"android:layout_below="@+id/home_page_top_lin"android:overScrollMode="never"android:scrollbars="none"><LinearLayout
android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"><android.support.v4.view.ViewPager android:id="@+id/home_page_vp"android:layout_width="match_parent"android:layout_height="150dp"></android.support.v4.view.ViewPager><include layout="@layout/co2" /><include layout="@layout/light" /><include layout="@layout/soil" /><include layout="@layout/air" /></LinearLayout></ScrollView></RelativeLayout>
几个布局都差不多，我这边就列出一个光照强度的布局。
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"><View
android:layout_width="match_parent"android:layout_height="1dp"android:background="#716c6c" /><RelativeLayout

android:layout_width="match_parent"android:layout_height="1dp"android:background="#716c6c" /></LinearLayout>
接着在MainActivity里面填充fragment数据，然后用viewpager来滑动。最后来绑定适配器。
private static final String TAG = "MainActivity";List<Fragment> fragmentList = new ArrayList<>();private ViewPager agricultureVp;private LinearLayout homeLin;private LinearLayout setLin;private LinearLayout helpLin;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);bangID();HomePageFragment homePageFragment = new HomePageFragment();SetFragment setFragment = new SetFragment();HelpFragment helpFragment = new HelpFragment();fragmentList.add(homePageFragment);fragmentList.add(setFragment);fragmentList.add(helpFragment);MyPageAdapter adapter = new MyPageAdapter(getSupportFragmentManager(), fragmentList);agricultureVp.setAdapter(adapter);}private void bangID() {agricultureVp = findViewById(R.id.main_vp);homeLin = findViewById(R.id.home_page_lin);setLin = findViewById(R.id.set_lin);helpLin = findViewById(R.id.help_lin);homeLin.setOnClickListener(this);setLin.setOnClickListener(this);helpLin.setOnClickListener(this);}@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.home_page_lin:agricultureVp.setCurrentItem(0);break;case R.id.set_lin:agricultureVp.setCurrentItem(1);break;case R.id.help_lin:agricultureVp.setCurrentItem(2);break;default:}}
}
MyPageAdapter适配器布局：
//创建fragmentList集合private List<Fragment> fragmentList;//构造方法实现传值public MyPageAdapter(FragmentManager fm, List<Fragment> fragmentList) {super(fm);this.fragmentList = fragmentList;}//返回fragmentList对象@Overridepublic Fragment getItem(int position) {return fragmentList.get(position);}//返回fragmentList对象个数@Overridepublic int getCount() {return fragmentList.size();}布局做好了，我们需要做一个自定义的对话框，需要用到alertdialog的知识。首先我们还是要先写一个一个alertdialog的布局。
<View
android:layout_width="match_parent"android:layout_height="1dp"android:background="#716c6c" /><RelativeLayout
android:layout_width="match_parent"android:layout_height="wrap_content"><com.makeramen.roundedimageview.RoundedImageView
android:id="@+id/light_img"android:layout_width="120dp"android:layout_height="120dp"android:src="@mipmap/guangzhao"app:riv_oval="true" /><TextView
android:id="@+id/light_intension_tv"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_alignTop="@+id/light_img"android:layout_margin="5dp"android:layout_toLeftOf="@+id/light_warn_img"android:layout_toRightOf="@+id/light_img"android:text="光照强度"android:textColor="#000000"android:textSize="20sp" /><RelativeLayout
android:id="@+id/light_relative"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_below="@+id/light_intension_tv"android:layout_margin="5dp"android:layout_toLeftOf="@+id/light_right_img"android:layout_toRightOf="@+id/light_img"><TextView
android:id="@+id/light_light_tv"android:layout_width="wrap_content"android:layout_height="wrap_content"android:gravity="center_vertical"android:text="光照"android:textColor="#100909"android:textSize="20sp" /><TextView
android:id="@+id/light_values_tv"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginLeft="15dp"android:layout_toRightOf="@+id/light_light_tv"android:gravity="center_vertical"android:text="200"android:textColor="#e80c0c"android:textSize="20sp" /></RelativeLayout><RelativeLayout
android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_alignBottom="@+id/light_img"android:layout_below="@+id/light_relative"android:layout_margin="5dp"android:layout_toLeftOf="@+id/light_right_img"android:layout_toRightOf="@+id/light_img"><TextView
android:id="@+id/light_set_tv"android:layout_width="wrap_content"android:layout_height="wrap_content"android:gravity="center_vertical"android:text="设定值:"android:textColor="#1fa433"android:textSize="15sp" /><TextView
android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginLeft="15dp"android:layout_toRightOf="@+id/light_set_tv"android:gravity="center_vertical"android:text="200"android:textColor="#605858"android:textSize="15sp" /></RelativeLayout><ImageView
android:id="@+id/light_right_img"android:layout_width="20dp"android:layout_height="60dp"android:layout_alignParentRight="true"android:layout_centerVertical="true"android:src="@mipmap/right" /><ImageView
android:id="@+id/light_warn_img"android:layout_width="50dp"android:layout_height="20dp"android:layout_alignParentRight="true"android:layout_alignParentTop="true"android:src="@mipmap/p2" /></RelativeLayout><View
android:layout_width="match_parent"android:layout_height="1dp"android:background="#716c6c" />
然后在ImgActivity里面定义一个按钮，IP，一个输入框，需要在里面使用handler来启动子线程。
private final long SPLASH_LENGTH = 2000;Handler handler = new Handler();private Button button;private String IP;private EditText editText;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_img);handler.postDelayed(new Runnable() { //使用handler的postDelayed实现延时跳转public void run() {AlertDialog.Builder builder = new AlertDialog.Builder(ImgActivity.this);View view = View.inflate(ImgActivity.this,R.layout.alert_dialog,null);builder.setView(view);builder.setCancelable(true);editText = view.findViewById(R.id.dialog_et);button = view.findViewById(R.id.dialog_btn);AlertDialog dialog = builder.create();dialog.show();button.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent intent = new Intent(ImgActivity.this, MainActivity.class);IP = editText.getText().toString();intent.putExtra("IP",IP);startActivity(intent);finish();}});}}, SPLASH_LENGTH);//2秒后跳转至应用主界面MainActivity}
首页上面的图片，也要实现手动滑动，同样的都是用fragment和viewpager的知识来实现。
View view =inflater.inflate(R.layout.fragment_home_page, container, false);bangID(view);ImgAFragment imgAFragment = new ImgAFragment();ImgBFragment imgBFragment = new ImgBFragment();fragmentImgList.add(imgAFragment);fragmentImgList.add(imgBFragment);MyImgPageAdapter adapter1 = new MyImgPageAdapter(getChildFragmentManager(), fragmentImgList);ImgVp.setAdapter(adapter1);最后也是用myimgadapter来绑定。
public class MyImgPageAdapter extends FragmentPagerAdapter {//创建fragmentList集合private List<Fragment> fragmentImgList;//构造方法实现传值public MyImgPageAdapter(FragmentManager fm, List<Fragment> fragmentImgList) {super(fm);this.fragmentImgList = fragmentImgList;}//返回fragmentList对象@Overridepublic Fragment getItem(int position) {return fragmentImgList.get(position);}//返回fragmentList对象个数@Overridepublic int getCount() {return fragmentImgList.size();}
}
公共类状态的标志位：
public class Status {public static int WaterPump = 0;public static int Blower = 0;public static int Roadlamp = 0;public static int Buzzer = 0;public static String resultStr;public static String TAG = "Status";}获取传感器的类：
public class App {private int airHumidity;private int PM25;private int airTemperature;private int soilTemperature;private int co2;private int soilHumidity;private int light;public int getAirHumidity() {return airHumidity;}public void setAirHumidity(int airHumidity) {this.airHumidity = airHumidity;}public int getPM25() {return PM25;}public void setPM25(int PM25) {this.PM25 = PM25;}public int getAirTemperature() {return airTemperature;}public void setAirTemperature(int airTemperature) {this.airTemperature = airTemperature;}public int getSoilTemperature() {return soilTemperature;}public void setSoilTemperature(int soilTemperature) {this.soilTemperature = soilTemperature;}public int getCo2() {return co2;}public void setCo2(int co2) {this.co2 = co2;}public int getSoilHumidity() {return soilHumidity;}public void setSoilHumidity(int soilHumidity) {this.soilHumidity = soilHumidity;}public int getLight() {return light;}public void setLight(int light) {this.light = light;}
}控制的类：
public class AppStatus {private int WaterPump;private int Blower;private int Roadlamp;private int Buzzer;private String result;public int getWaterPump() {return WaterPump;}public void setWaterPump(int waterPump) {WaterPump = waterPump;}public int getBlower() {return Blower;}public void setBlower(int blower) {Blower = blower;}public int getRoadlamp() {return Roadlamp;}public void setRoadlamp(int roadlamp) {Roadlamp = roadlamp;}public int getBuzzer() {return Buzzer;}public void setBuzzer(int buzzer) {Buzzer = buzzer;}public String getResult() {return result;}public void setResult(String result) {this.result = result;}
}
接下来我们就是需要打开农业接口的文件，我们通过获取传感器来获取数据。所以这个时候我们可以定义一个公共的类，和一个公共的方法，在这里我们可以不用AsyncHttpClient，可以用OkHttpClient，这样的话速度更快一点。记得要postJsonByOkHttp来封装东西。
private static OkHttpClient client = new OkHttpClient();public static void sendOkHttpRequest(String address,okhttp3.Callback callback){Request request = new Request.Builder().url(address).build();client.newCall(request).enqueue(callback);}public static void postJsonByOkHttp(String url, JSONObject jsonObject,okhttp3.Callback callback){MediaType mediaType = MediaType.parse("application/json;Charset=UTF-8");RequestBody requestBody = RequestBody.create(mediaType,jsonObject.toString());Request request = new Request.Builder().url(url).post(requestBody).build();client.newCall(request).enqueue(callback);}
我们在devicecontrol的类里面写八个公共的方法，来控制开关的状态。

接着在homepagefragment里面写一个获取数据和控制的方法接下来。可以在添加一个progressdialog的进度条，感受一下OKHTTPclient的速度。

然后在四个页面来判断打开开关的状态，和实现改变图片的功能。这时候我们 可以用到devicecontrol了。用status里面e 标志位来判断它们的状态
