智能农业项目简介
智能农业项目总结
首先，先在build.gradle添加项目所需要的所有的数据包
compile 'com.makeramen:roundedimageview:2.2.1'
compile 'com.loopj.android:android-async-http:1.4.9'
compile 'com.google.code.gson:gson:2.8.2'
implementation 'com.squareup.okhttp3:okhttp:3.10.0'一.创建页面布局，实现界面转换（举例首页布局）

图片展示
二.Java文件（fragment,gson,util）
实现网络请求，获取信息并进行解析得到实时信息，放到页面所属位置
获取各个开关的状态，并获取沙盘的数据，可以进行控制（操作界面中各个选项，跳转到具体设施操作界面，加载界面时获取服务器中各个设施状态，判断设施状态显示界面中按钮状态）
点击按钮控制，开关图片需要变化，需要用标识位来显示，转到其他页面，也不需要重新更新数据，依然可以获取
公共类与全局变量的使用
本项目需要网络请求很多次，为减轻代码量，可以写一个公共类，在里面写方法，然后进行调用。
使用OKHttp
创建OKHttp类
public class OkHttp {
//定义静态url路径
private static final String BASE_URL = "http://"+ StartActivity.URL+":8890/type/jason/action/";
private static OkHttpClient client = new OkHttpClient();
public static final MediaType mediaType = MediaType.parse("application/json;charset=UTF-8");
public static void sendOkHttpRequest(String url, okhttp3.Callback callback) {
Request request = new Request.Builder().url(getAbsoluteUrl(url)).build();
client.newCall(request).enqueue(callback);
}
//post方法，获取JSON格式的数据
public static void postJSONByOkhttp(String url, String json,int number, Callback callback) {
try {
JSONObject jsonObject=new JSONObject();
jsonObject.put(json,number);
RequestBody requestBody = RequestBody.create(mediaType, jsonObject.toString());
Request request = new Request.Builder().url(getAbsoluteUrl(url)).post(requestBody).build();
client.newCall(request).enqueue(callback);
} catch (JSONException e) {
e.printStackTrace();
}
}
//变换的URL
private static String getAbsoluteUrl(String relativeUrl) {
return BASE_URL + relativeUrl;
}
}控制开关功能
首先设置监听，跳转到开关界面，接着进行点击图片实现控制开关，并改变图片的内容
public class AirActivity extends AppCompatActivity implements View.OnClickListener{
private ImageView openFanImg;
private ImageView openLightImg;
private ImageView openPumpImg;
private ImageView openAlertImg;
private TextView airTemp;
private TextView airWet;
private void modifierBlowerStatus() {
if (Status.Blower == 0) {
openFanImg.setImageResource(R.mipmap.dakaifengshan);
DeviceControl.Result = 0;
} else if (Status.Blower == 1) {
openFanImg.setImageResource(R.mipmap.dakaifengshan2);
DeviceControl.Result = 1;
}
}
private void modifierBuzzerStatus() {
//这时候全局变量就有作用了
if (Status.Buzzer == 0) {
openAlertImg.setImageResource(R.mipmap.dakaibaojing);
//通过状态来改变标志位，用标志位来改变以后再这个页面图片的转换
//标志位依然是全局的变量，会在实现设备开关的类进行定义
DeviceControl.alertResult = 0;
} else if (Status.Buzzer == 1) {
openAlertImg.setImageResource(R.mipmap.dakaibaojing2);
DeviceControl.alertResult = 1;
}
}
private void modifierLightStatus() {
if (Status.Roadlamp == 0) {
openLightImg.setImageResource(R.mipmap.dakaiguangzhao);
DeviceControl.lightResult = 0;
} else if (Status.Roadlamp == 1) {
openLightImg.setImageResource(R.mipmap.dakaiguangzhao2);
DeviceControl.lightResult = 1;
}
}
private void modifierPumpStatus() {
if (Status.WaterPump == 0) {
openPumpImg.setImageResource(R.mipmap.dakaishui);
DeviceControl.pumpResult = 0;
} else if (Status.WaterPump == 1) {
openPumpImg.setImageResource(R.mipmap.dakaishui2);
DeviceControl.pumpResult = 1;
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_air);
bangID();
//下面四个方法都是判断沙盘上各个控件的状态，如果有开的，就需要改变图片
modifierBlowerStatus();
modifierBuzzerStatus();
modifierLightStatus();
modifierPumpStatus();
airTemp.setText(MainActivity.airTemperature+"");
airWet.setText(MainActivity.airHumidity+"");
}
private void bangID() {
openFanImg = findViewById(R.id.air_fan_img);

//调用开报警的方法
DeviceControl.openAlert(MainActivity.basicUrl, AirActivity.this);
Toast.makeText(this, "开警报", Toast.LENGTH_SHORT).show();
} else if (DeviceControl.alertResult == 1) {
openAlertImg.setImageResource(R.mipmap.dakaibaojing);
Intent intent = getIntent();

break;
