智能农业项目小结
项目的实现原理
通过编写一个手机APP，然后通过它来获取农业基地的信息，然后根据信息反馈，来通过控制基地里面的设施来调节。这里只介绍手机APP的实现。首先呢，先编写好编写好APP的布局，以及点击事件的监听，其次，通过对局域网的访问来获取基地的数据信息，最后通过对服务端发送命令来打开设备。
项目实现
这里呢就不把项目全列出来了，就只介绍一下项目的核心内容。
1.编写好编写好APP的布局，以及点击事件的监听。
这里就只给个布局吧，功能接下来会写的
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.zhang.zhinenglongye.Kongqixiangqing">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="60dp">
<TextView
android:layout_width="match_parent"
android:layout_height="60dp"
android:gravity="center"
android:text="空气详情"
android:textColor="#7BCE44"
android:textSize="30sp" />
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_marginTop="10dp"
android:src="@mipmap/fanhuianniu" />
RelativeLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="150dp"
android:background="@mipmap/co2beijng"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="75dp"
android:gravity="center"
android:text="当前CO2浓度"
android:textColor="#FFE29D02"
android:textSize="20sp" />
<TextView
android:layout_width="match_parent"
android:layout_height="75dp"
android:gravity="center"
android:text="CO2设定的范围"
android:textColor="#FFE29D02"
android:textSize="20sp" />
LinearLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/pic1"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_marginLeft="30dp"
android:src="@mipmap/dakaifengshan" />
<ImageView
android:id="@+id/pic2"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_marginLeft="20dp"
android:layout_toRightOf="@+id/pic1"
android:src="@mipmap/dakaiguangzhao" />
<ImageView
android:id="@+id/pic3"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_below="@+id/pic1"
android:layout_marginLeft="30dp"
android:src="@mipmap/dakaishui" />
<ImageView
android:id="@+id/pic4"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_below="@+id/pic2"
android:layout_marginLeft="20dp"
android:layout_toRightOf="@+id/pic3"
android:src="@mipmap/dakaibaojing" />
RelativeLayout>
LinearLayout>
RelativeLayout>
布局上主要是给出了四个按钮，分别实现服务端的风扇，水泵，蜂鸣，光照的功能。
2.通过对局域网的访问来获取基地的数据信息
String di="http://"+Izhi.id+":8890/type/jason/action/getSensor?username=admin";
Httpurl.getByOkHttp(di, new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
String as=response.body().string();
try {
JSONObject object = new JSONObject(as);
final int a1 = object.getInt("co2");//获取农业基地的数据信息
final int a2 = object.getInt("light");
final int a3 = object.getInt("soilTemperature");
final int a4 = object.getInt("soilHumidity");
final int a5 = object.getInt("airTemperature");
final int a6 = object.getInt("airHumidity");
getActivity().runOnUiThread(new Runnable() {
@Override//OkHttp不能进行UI操作.所以要单独建线程
public void run() {//将获取的信息显示给用户。这里的布局页面没有写
q1.setText(a1 + "");
q2.setText(a2 + "");
q3.setText(a3 + "");
q4.setText(a4 + "");
q5.setText(a5 + "");
q6.setText(a6 + "");
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
});写一个OkHttp的公共类
public class Httpurl {
private static final String BASE="http://"+Izhi.id+":8890/type/jason/action/";
private static OkHttpClient okHttpClient=new OkHttpClient();
//用来获取数据信息
public static void getByOkHttp(String url, Callback callback){
Request request=new Request.Builder().url(getAbsoluteUrl(url)).build();
okHttpClient.newCall(request).enqueue(callback);
}
//用来发送JSON控制信息
public static void postJsonOkHttp(String url, JSONObject jsonObject, Callback callback){
MediaType mediaType=MediaType.parse("application/json;charset=utf-8");
RequestBody requestBody=RequestBody.create(mediaType,jsonObject.toString());
Request request=new Request.Builder().url(getAbsoluteUrl(url)).post(requestBody).build();
okHttpClient.newCall(request).enqueue(callback);
}
private static String getAbsoluteUrl(String url){
return BASE+url;
}3.通过对服务端发送命令来打开设备
public class Kongqixiangqing extends AppCompatActivity {
private ImageView pic1;
private ImageView pic2;
private ImageView pic3;
private ImageView pic4;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_kongqixiangqing);
pic1=findViewById(R.id.pic1);
pic2=findViewById(R.id.pic2);
pic3=findViewById(R.id.pic3);
pic4=findViewById(R.id.pic4);
//这里用来判断进入时按钮的状态
if(Izhi.shui==1){
pic3.setImageResource(R.mipmap.dakaishui2);
}else if(Izhi.shui==0){
pic3.setImageResource(R.mipmap.dakaishui);
