自定义android程序一段时间无操作后的功能

项目中遇见一个这样的需求，就是当软件在一定时间没有操作时候需要弹出广告页面，当点击广告页面时又进行软件操作，也就是广告要在软件打开并且处于未操作状态才会出来。

方法一：用handler+onTouchEvent实现延时发送请求

这个操作最好放到BaseActivity里进行。

[代码]java代码：

private Handler handler = new Handler();
private long time=1000*60*5;
@Override
public boolean onTouchEvent(MotionEvent event) {
    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
            handler.removeCallbacks(runnable);
            break;
        case MotionEvent.ACTION_UP:
            startAD();
            break;
    }
    return super.onTouchEvent(event);
}
private Runnable runnable = new Runnable() {
    @Override
    public void run() {
       跳转到广告页面
    }
};
public void startAD() {
    handler.removeCallbacks(runnable);
    handler.postDelayed(runnable, time);
}

方法二：通过PowerManager.WakeLock实现

判断屏幕是否变暗的这个思路去实现。

方法三：使用双线程来实现 (时间超时或者在接收到锁屏广播的时候显示)

可以在application或者activity的oncreated方法里面启动监听。

下面是启动一个服务，当用户按锁屏键锁屏的时候会发送一个广播，我们在服务中接受到广播后可以屏蔽系统的锁屏，显示我们自己的锁屏：

[代码]java代码：

public class ScreenService extends Service {  
    KeyguardManager mKeyguardManager = null;     
    private KeyguardLock mKeyguardLock = null;    
    BroadcastReceiver mMasterResetReciever;  
    @Override 
    public IBinder onBind(Intent intent) {  
        // TODO Auto-generated method stub  
        return null;  
    }  
     @Override    
        public void onCreate() {   
             //Log.e("ScreenService","onCreate()");  
            // TODO Auto-generated method stub   
            startScreenService();  
            super.onCreate();     
          }     
           
     @Override    
     public void onStart(Intent intent, int startId) {    
        // Log.e("ScreenService","onStart");  
        // TODO Auto-generated method stub     
         startScreenService();  
      }  
            
     private void startScreenService(){  
         mKeyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);     
         mKeyguardLock = mKeyguardManager.newKeyguardLock("");  
            
            
         mKeyguardLock.disableKeyguard();     
            
         //Intent.ACTION_SCREEN_OFF  
         mMasterResetReciever = new BroadcastReceiver() {     
             @Override 
                public void onReceive(Context context, Intent intent) {     
                 try {   
                         Intent i = new Intent();     
                         i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);   
                         i.setClass(context, ScreenSaverActivity.class);                          
                         context.startActivity(i);   
                 } catch (Exception e) {                          
                     Log.i("mMasterResetReciever:", e.toString());     
                 }     
             }     
         };             
       registerReceiver(mMasterResetReciever, new IntentFilter(Intent.ACTION_SCREEN_OFF));     
     }  
        
     @Override 
    public void onDestroy() {  
        //Log.e("ScreenService","onDestroy()");  
        super.onDestroy();  
        unregisterReceiver(mMasterResetReciever);    
         ScreenService.this.stopSelf();  
     }  
}
