赵雅智：service_startService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_start"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:onClick="click"
        android:text="context.startService" />

    <Button
        android:id="@+id/btn_stop"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/btn_start"
        android:onClick="click"
        android:text="context.strpService" />

</RelativeLayout>

注册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) {
		/*
		 * 启动服务
		 */
		case R.id.btn_start:
			this.startService(service);
			break;
		/*
		 * 停止服务
		 */
		case R.id.btn_stop:
			this.stopService(service);
			break;
		default:
			break;
		}
	}

}

运行结果

点击context.startService--->点击context.stopService。生命周期为



点击context.startService--->home键--->点击context.startService--->点击context.startService...--->点击context.stopService
