android aidl通讯两个APP之间的应用

一：数据提供端代码（数据提供APP）

1.java代码：Service

package com.example.remoteaidi;import com.example.remoteaidi.aidl.StudentAidl;import android.app.Service;import android.content.Intent;import android.os.IBinder;import android.os.RemoteException;public class StudentService extends Service {private String[] studentNo = {"王1","2","王3","王4","王月4","宋6"};private IBinder binder = new StudentQueryBinder();@Overridepublic IBinder onBind(Intent intent) {return binder;}class StudentQueryBinder extends StudentAidl.Stub {@Overridepublic String getStudent(int no) throws RemoteException {int l = studentNo.length;if(l<0) {no = 0;}if(no>=l) {no = l - 1;}return studentNo[no];}}}

aidl文件

package com.example.remoteaidi.aidl;interface StudentAidl {String getStudent(int no);}

二：请求端代码

package com.example.aidlclient;import com.example.remoteaidi.aidl.StudentAidl;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.View;import android.widget.EditText;import android.widget.TextView;public class MainActivity extends Activity {private ServiceConnectionImpl sci ;private StudentAidl student;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Intent intent = new Intent();intent.setAction("student.query");sci = new ServiceConnectionImpl();bindService(intent, sci, BIND_AUTO_CREATE);}public void queryOnClick(View v) {EditText et_no_text = (EditText) findViewById(R.id.et_no_text);String no = et_no_text.getText().toString();String sname;try {sname = student.getStudent(new Integer(no));TextView tv_no = (TextView) findViewById(R.id.tv_no);tv_no.setText(sname);} catch (NumberFormatException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (RemoteException e) {// TODO Auto-generated catch blocke.printStackTrace();}}class ServiceConnectionImpl implements ServiceConnection {@Overridepublic void onServiceConnected(ComponentName name, IBinder service) {student = StudentAidl.Stub.asInterface(service);}@Overridepublic void onServiceDisconnected(ComponentName name) {student = null;}}@Overrideprotected void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();if(sci != null) {unbindService(sci);}}}

aidl文件与上一个aidl文件相同

package com.example.remoteaidi.aidl;interface StudentAidl {String getStudent(int no);}
