I am developing an app in which i am using custom list tab,By using this custom list tab i am rendering some child activities, and some of the child activities are having some soft key pad functionality now the problem is when i click on the back hard key(when the soft key pad is on) it is simply killing the activity with out firing OnkeyDown() and onBackpress() events and it is firing onDestroy() event method and this issue is specially occurring in HTC Devices. And the other devices(samsung) are working as exppect i.e. hiding the soft key pas on pressing hard back key. how to this issue?

谢谢，

推荐答案

您可以尝试重写onKeyDown和的onkeyup这样的：

You can try overriding onKeyDown and onKeyUp like this:

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

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

我记得读这是Android的版本比2.1更早问题

I remember reading this to be a problem in Android versions earlier than 2.1
