Question

我正在开发一个安卓应用程序。如果应用程序处于非 Activity 状态或未使用 5 分钟，它应该导航到另一个 Activity 。我对此一无所知。请帮忙。提前致谢。

尝试在您的 Activity 中添加以下代码..

代码

public static final long DISCONNECT_TIMEOUT = 300000; 
// 5 min = 5 * 60 * 1000 ms=300000

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         

        Intent i=new Intent(this,newActivity.class);
            startActivity(i);
    }
};

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();
}
