onBack pressed隐藏不破坏活动 [英] onBackPressed to hide Not destroy activity

问题描述

我知道如何取消返回键preSS，使活动/主窗口中保持可见：

i know how to cancel back keypress, so that the activity / main window stays visible:

public void onBackPressed() {
    return;             
}

我的目的不过是隐藏的活动，没有完成它，你怎么做，在onBack pressed事件？

my aim is to hide the activity, however, without finishing it, how do you do that in the onBackPressed event?

即。我想获得尽可能的onPause（），而不是唤起onBack pressed（）默认的行为，本质上调用完成（）。另一种方式把它的是，我想模仿onUserLeaveHint（）？

i.e. I would like to get as far as onPause(), but not evoke the onBackPressed() default behaviour that essentially calls finish(). another way to put it is that i would like to mimic onUserLeaveHint() ?

任何帮助AP preciated！

any help appreciated!

推荐答案

如果你想模仿的具体活动的主页按钮即可做到这一点：

If you want to mimic the "Home" button on specific Activities just do this:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        moveTaskToBack(true);
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

这将移动工作背景。当您返回，这将是因为它是。

It will move the Task to background.. when you return, it will be as it was.
