本文主要是介绍Android中BindService方式使用的例子，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
MainActivity.java如下package com.example.bindservice;
import com.example.bindservice.BindService.MyBinder;
import android.os.Bundle;
import android.os.IBinder;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
private Button startBtn;
private Button stopBtn;
private boolean flag;
private static final String TAG = "BindService";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
flag = false;
startBtn = (Button)this.findViewById(R.id.startBtn);
stopBtn = (Button)this.findViewById(R.id.stopBtn);
startBtn.setOnClickListener(listener);
stopBtn.setOnClickListener(listener);
}
private OnClickListener listener = new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.startBtn:
bindService();
break;
case R.id.stopBtn:
unBind();
break;
default:
break;
}
}
};
private void bindService(){
Intent intent = new Intent(MainActivity.this,BindService.class);
bindService(intent, conn, Context.BIND_AUTO_CREATE);
}
private void unBind(){
if(flag == true){
Log.i(TAG, "BindService-->unBind()");
unbindService(conn);
flag = false;
}
}
private ServiceConnection conn = new ServiceConnection() {
@Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
}
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
// TODO Auto-generated method stub
MyBinder binder = (MyBinder)service;
BindService bindService = binder.getService();
bindService.MyMethod();
flag = true;
}
};
@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;
}
}
BindService.java如下
package com.example.bindservice;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.util.Log;
public class BindService extends Service {
private static final String TAG = "BindService";
public void MyMethod(){
for(int i = 0; i < 100; i++)
{
Log.i(TAG, "BindService-->MyMethod()");
}
}
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return myBinder;
}
public class MyBinder extends Binder{
public BindService getService(){
return BindService.this;
}
}
private MyBinder myBinder = new MyBinder();
}
strings.xml如下
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">BindService</string>
<string name="action_settings">Settings</string>
<string name="hello_world">Hello world!</string>
<string name="stopBtn">stopBtn</string>
<string name="startBtn">startBtn</string>
</resources>
main.xml如下
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<Button
android:id="@+id/startBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView1"
android:layout_below="@+id/textView1"
android:layout_marginTop="18dp"
android:text="@string/startBtn" />
<Button
android:id="@+id/stopBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="@+id/startBtn"
android:layout_below="@+id/startBtn"
android:layout_marginTop="29dp"
android:text="@string/stopBtn" />
</RelativeLayout>
AndroidManifest.xml如下
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bindservice"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.bindservice.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="com.example.bindservice.BindService"></service>
</application>
</manifest>
