Android 程式定時自啟動

最近，看了api中例子程式定時自啟動，整理了一下共分享給大家；

首先，建立AutouStartActivity類

package com.start.app;import android.app.Activity;import android.app.AlarmManager;import android.app.PendingIntent;import android.content.Context;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class AutouStartActivity extends Activity { final String MYACTION = "android.intent.action.STARTMYAP";   AlarmManager am = null;      Intent intent = null;         /** Called when the activity is first created. */      @Override      public void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.main);                    Button btn = (Button)this.findViewById(R.id.start);          btn.setOnClickListener(new OnClickListener(){                @Override              public void onClick(View v) {                              AutouStartActivity.this.finish();              }          });         am=(AlarmManager)this.getSystemService(Context.ALARM_SERVICE);       intent=new Intent(MYACTION);    }          @Override    protected void onDestroy() {               PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent, 1);           am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+5000, pi);//15秒鐘以後啟動      super.onDestroy();    }}

然後建立接收器

package com.start.app;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;public class AppReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent in) {if(in!=null){if(in.getAction().equals("android.intent.action.STARTMYAP")){Intent i=new Intent(context, AutouStartActivity.class);i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);context.startActivity(i);}}}}

最後，別忘了註冊接收器；

<receiver android:name=".AppReceiver">                 <intent-filter>                   <action android:name="android.intent.action.STARTMYAP"/>               </intent-filter>          </receiver>  

ok,搞定！
