赵雅智：service_bindService生命周期

案例演示

布局文件

<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"
    tools:context="${packageName}.${activityClass}" >

    <Button
        android:id="@+id/btn_bind"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/btn_stop"
        android:onClick="click"
        android:text="context.bindService" />

    <Button
        android:id="@+id/btn_unbind"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/btn_bind"
        android:onClick="click"
        android:text="context.unbindService" />


</RelativeLayout>

注冊service

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android_servicedemo"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.android_servicedemo.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="ServiceTese"
            android:permission="com.example.permission.servers" >
            <intent-filter>
                <action android:name="com.example.serversdemo.action" />
            </intent-filter>
        </service>
    </application>

</manifest>

主activity

package com.example.android_servicedemo;


import android.app.Activity;
import android.app.Service;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.util.Log;
import android.view.View;

public class MainActivity extends Activity {
	private Intent service;
	MyConn myConn;
	public static final String TAG = "MainActivity";

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		// 隐士意图的启动
		service = new Intent();
		service.setAction("com.example.serversdemo.action");
	}

	public void click(View v) {
		int id = v.getId();
		switch (id) {
		case R.id.btn_bind:
			// con:该參数是一个ServiceConnection对象。该对象用于监听訪问者与service之间的连接情况
			// flag:指定绑定时是否自己主动创建service(假设service还没创建)0：不自己主动创建。BIND_AUTO_CREATE自己主动创建
			myConn = new MyConn();
			this.bindService(service, myConn, Service.BIND_AUTO_CREATE);
			break;
		case R.id.btn_unbind:
			if (myConn != null) {
				this.unbindService(myConn);
			}
			break;
		default:
			break;
		}
	}

	class MyConn implements ServiceConnection {
		/**
		 * 当连接成功的时候回调此方法
		 */
		@Override
		public void onServiceConnected(ComponentName name, IBinder service) {
			// TODO Auto-generated method stub
			Log.i(TAG, "---------onServiceConnected" + name);
		}

		/**
		 * 当service所在的宿主矜持因为异常终止或因为其它原因终止，导致该service与訪问者之间断开连接的时候回调
		 */
		@Override
		public void onServiceDisconnected(ComponentName name) {
			Log.i(TAG, "---------onServiceDisconnected" + name);

		}

	}
}

执行结果

点击context.bindService--->点击context.unbindService。生命周期为

点击context.bindService--->home键--->点击context.bindService--->点击context.bindService..

.--->点击context.stopService

所以仅仅能点击一次unbind
