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。

public class MainActivity extends Activity {

private Handler mHandler01 = new Handler();

private Handler mHandler02 = new Handler();

/* 上一次User有动作的Time Stamp */

private Date lastUpdateTime;

/* 计算User有几秒没有动作的 */

private long timePeriod;

/* 静止超过N秒将自动进入屏保 */

private float mHoldStillTime = 10;

/*标识当前是否进入了屏保*/

private boolean isRunScreenSaver;

/*时间间隔*/

private long intervalScreenSaver = 1000;

private long intervalKeypadeSaver = 1000;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

/**

* 计时线程

*/

private Runnable mTask01 = new Runnable() {

@Override

public void run() {

Date timeNow = new Date(System.currentTimeMillis());

/* 计算User静止不动作的时间间距 */

/**当前的系统时间 - 上次触摸屏幕的时间 = 静止不动的时间**/

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();

}
