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

package="bw.com.week2_test">

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

六, MainActivity.java

    

/**

* 3, 通过事件分发, 左侧控制左侧的移动, 右侧控制右侧的移动, 中间控制一起的移
* 4, 点击 每个条目, 通过aidl 获取服务端返回的数据  -- 两个app , Servier -- App
*/
public class MainActivity extends AppCompatActivity {

//TODO 初始化控件

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.aidlpackage 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
