ButterKnife 加载控件 + xUtils 获取数据+ Fresco 显示图片 + 通过事件分发控制移动 + 通过AIDL获取数据

一, 导入jar包

      xUtils.jar  +  gson.jar

二, 添加依赖

compile 'com.jakewharton:butterknife:8.8.1'
compile 'com.jakewharton:butterknife-compiler:8.8.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.facebook.fresco:fresco:1.5.0'

三, MyApp.java

public class MyApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        //初始化Fresco
        Fresco.initialize(this);

        //初始化xUtils
        x.Ext.init(this);
        x.Ext.setDebug(true);
    }
}

   四, 清单文件

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="bw.com.week2_test">

        <uses-permission android:name="android.permission.INTERNET"/>

    private MyAidl myAidl;
    private ServiceConnection connection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            myAidl = MyAidl.Stub.asInterface(service);
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {
        }
    };

        bindService(intent,connection,BIND_AUTO_CREATE);

    //TODO 解绑服务
    @Override
    protected void onStop() {
        super.onStop();
        unbindService(connection);
    }



}

七, MyAdapter.java

public class MyAdapter extends BaseAdapter{
    private List<Qubaobei.DataBean> data;
    private Context context;

    public MyAdapter(Context context,List<Qubaobei.DataBean> data)
    {
        this.data = data;
        this.context = context;
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        return data.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder viewHolder;

        if(convertView==null)
        {
            convertView = LayoutInflater.from(context).inflate(R.layout.item_rv,parent,false);
            viewHolder = new ViewHolder(convertView);
            convertView.setTag(viewHolder);
        }else
        {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        //TODO Fresco 获取图片
        Uri uri = Uri.parse(data.get(position).getPic());
        viewHolder.sdv.setImageURI(uri);

        viewHolder.titleTv.setText(data.get(position).getTitle());

        return convertView;
    }

    class ViewHolder
    {
        @BindView(value = R.id.sdv_id)
        SimpleDraweeView sdv;

        @BindView(value = R.id.title_id)
        TextView titleTv;

        public ViewHolder(View itemView) {
            //TODO 绑定ButterKnife
            ButterKnife.bind(this,itemView);
        }
    }
}

八, Qubaobei.java   - - GsonFormant 生成的实体类

九, 复制服务端的src/main 目录中的aidl文件夹  -- 然后编译

十, 服务器端

        1, 在src /main 目录下创建 aidl 文件 

        MyAidl.aidl

package bw.com.server;

interface MyAidl {

    String getInfo();
}

       

  2,  编译生成同名的的.java 文件  -- MyAidl.java

 3,  定义 MyService.java 类

        

public class MyService extends Service {

    private MyAidl.Stub stub = new MyAidl.Stub() {
        @Override
        public String getInfo() throws RemoteException {
            return "AIDL 返回的数据";
        }
    };

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return stub;
    }
}

4,在服务器的清单文件夹中, 注册Service

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="bw.com.server">

    <application android:allowBackup="true" android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true" android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <!--注册Service-->
        <service android:name=".MyService">
            <intent-filter>
                <action android:name="com.bw.aidl"/>
            </intent-filter>
        </service>
    </application>

</manifest>

十一,  运行的时候, 先运行Service ,  然后在运行App
