Android-避免破坏活动，只需在按下“后退"按钮时停止或暂停该活动 [英] Android - Avoiding an activity to destroy, just stopping or pausing it when pushing the back button

问题描述

按下返回按钮时，我想暂停或将应用程序置于后台，我不希望应用程序进入销毁状态.问题是当我重写onKeyDown并强制使用onPause暂停或停止应用程序时，唤醒锁和应用程序崩溃时会出现一些问题，但是当我按下主屏幕按钮时，我会使用onPause方法，而且我也没有例外，这很奇怪!!

I would like to pausing or putting the application on background when pressing the back button, I don't want the application to go through the destroy state. Things are when I override onKeyDown and when I force to pause or stop the application by using onPause, I have some issuees with the wakelock and application crash, but when I press home button I go through onPause method and I have no exception, it's weird!!

推荐答案

答案是

public boolean onKeyDown(int keyCode, KeyEvent event)
{

    if (keyCode == KeyEvent.KEYCODE_BACK)
    {
        moveTaskToBack(true);
        return true; // return
    }

    return false;
}
