新建一个项目充当发送者
1.创建一个以.aidl为后缀名的文件
IMyService.aidl
package com.example.aidldemo
interface IMyService{
String getValue();
String getName();
String getPrice();
}
系统会在gen目录中自动创建一个IMyService类
2.编写一个服务 并在服务中实现IMyService接口
private IMyservice.Stub binder = new IMyservice.Stub() {
public String getValue() throws RemoteException {
// TODO Auto-generated method stub
return "Android";
}
public String getName() throws RemoteException {
// TODO Auto-generated method stub
return "hello world";
}
public float getPrice() throws RemoteException {
// TODO Auto-generated method stub
return 10.0F;
}
};
在manifase中注册MyService添加android:process=":remote"
由于需要在其他应用中使用，所以要在remote之前要添加冒号
给service添加过滤器
<intent-filter >
<action android:name="com.example.aidldemo.IMyservice"/>
</intent-filter>
另外建一个项目充当接受者
把上面的.aidl文件复制到这个项目中，报名要相同
在布局文件中放一个textview用来接受value
放三个button，第一个用来bind服务 第二个用来显示向textview赋值 第三个解绑
在mainavtivity类
package com.example.aidlkhd;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.os.RemoteException;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.example.aidldemo.IMyservice;
public class MainActivity extends Activity {
private Button button1,button2,button3;
private TextView textview;
private IMyservice iservice = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (Button) findViewById(R.id.button1);
button2 = (Button) findViewById(R.id.button2);
button3 = (Button) findViewById(R.id.button3);
textview = (TextView) findViewById(R.id.textview);
}
public void bind(View v){
Intent service = new Intent(IMyservice.class.getName());
bindService(service,connection , BIND_AUTO_CREATE);
}
public void getdata(View v){
try {
textview.setText("运行结果="+iservice.getValue());
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void unbind(View v){
unbindService(connection);
}
private ServiceConnection connection = new ServiceConnection(){
public void onServiceConnected(ComponentName arg0, IBinder arg1) {
// TODO Auto-generated method stub
//从远程service中获得AIDL实例化对象
iservice = IMyservice.Stub.asInterface(arg1);
System.out.println("Bind Success:"+iservice);
}
public void onServiceDisconnected(ComponentName arg0) {
// TODO Auto-generated method stub
iservice = null;
}
};
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
