Question

这是我的代码

public class LogoutService extends Service {
    public static CountDownTimer timer;

    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        super.onCreate();
        timer = new CountDownTimer(1 * 60 * 1000, 1000) {
            public void onTick(long millisUntilFinished) {
                //Some code
                Log.v("Timer::", "Service Started");
            }

            public void onFinish() {
                Log.v("Timer::", "Call Logout by Service");
                // Code for Logout
                stopSelf();
            }
        };
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }
}

Answer 1

您可以使用默认方法找到用户互动：

@Override public void onUserInteraction() {
 super.onUserInteraction(); 
}

使用此方法检查用户交互，如果在时间限制后未找到任何交互，请调用注销方法。

创建一个需要由所有活动扩展的BaseActivity类。

public class MyBaseActivity extends Activity {

    public static final long DISCONNECT_TIMEOUT = 900000; // 15 min = 15 * 60 * 1000 ms

    private Handler disconnectHandler = new Handler(){
        public void handleMessage(Message msg) {
        }
    };

    private Runnable disconnectCallback = new Runnable() {
        @Override
        public void run() {
            // Perform any required operation on disconnect  

           // Logout from app
        }
    };

    public void resetDisconnectTimer(){
        disconnectHandler.removeCallbacks(disconnectCallback);
        disconnectHandler.postDelayed(disconnectCallback, DISCONNECT_TIMEOUT);
    }

    public void stopDisconnectTimer(){
        disconnectHandler.removeCallbacks(disconnectCallback);
    }

    @Override
    public void onUserInteraction(){
        resetDisconnectTimer();
    }

    @Override
    public void onResume() {
        super.onResume();
        resetDisconnectTimer();
    }

    @Override
    public void onStop() {
        super.onStop();
        stopDisconnectTimer();
    }
}

在其他方面，这也可行。

public class MyBaseActivity extends Activity {

   public static final int IDLE_DELAY_MINUTES = 15; // 15 min 
        @Override
    public void onUserInteraction() {
        super.onUserInteraction();
        delayedIdle(IDLE_DELAY_MINUTES);
    }

    Handler _idleHandler = new Handler();
    Runnable _idleRunnable = new Runnable() {
        @Override
        public void run() {
            //handle your IDLE state

      // Logout from app
        }
    };

    private void delayedIdle(int delayMinutes) {
        _idleHandler.removeCallbacks(_idleRunnable);
        _idleHandler.postDelayed(_idleRunnable, (delayMinutes * 1000 * 60));
    }

        }

Answer 3

您应该使用Handler。像

一样使用它

 android.os.Handler handler = new android.os.Handler(); //declear them globly
        Runnable runnable=null;

在Runnable内初始化onCreate()，如

runnable = new Runnable() {
            @Override
            public void run() {
            finish();
            }
        };

在代码中复制这两种方法

void start() {
    handler.postDelayed(runnable, TimeUnit.MINUTES.toMillis(15));
}
void stop(){
    handler.removeCallbacks(runnable);
}

覆盖onUserInteraction()的{{1}}方法并致电Activity和start()

stop()

在可运行的初始化之后，不要忘记从@Override public void onUserInteraction() { super.onUserInteraction(); stop(); start(); }调用start（）方法。它的onCreate()方法会在用户处于非活动状态后15分钟后调用，在那里执行您的任务（您希望完成run()或其他内容）

将此Activity粘贴到您的代码中

BaseActivity

现在扩展import android.os.Bundle; import android.os.Handler; import android.support.annotation.Nullable; import android.support.v7.app.AppCompatActivity; import android.util.Log; import java.util.concurrent.TimeUnit; public class BaseActivity extends AppCompatActivity { private static android.os.Handler handler = new android.os.Handler(); private static Runnable runnable = null; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (handler == null) { handler = new Handler(); } else { handler.removeCallbacks(runnable); } if (runnable == null) runnable = new Runnable() { @Override public void run() { //do your task here } }; start(); } @Override public void onUserInteraction() { super.onUserInteraction(); stop(); start(); } void start() { handler.postDelayed(runnable, TimeUnit.MINUTES.toMillis(15)); } void stop() { handler.removeCallbacks(runnable); } }除BaseActivity之外的所有Activity，或者像这样。

AppCompatActivity

您是否在public class HomeActivity extends BaseActivity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_home); } }方法内执行任务，我建议您从run()方法启动另一个Activity并清除活动堆栈，因为run()仅适用于1 { {1}}。

由于用户的InActive，如何在15分钟后获得自动退出表单活动？
