公共布尔的onkeydown(INT键code,KeyEvent的事件){
如果(键code == KeyEvent.KEY code_BACK和放大器;&安培; event.getRepeatCount()== 0){
//做一些事情就回来了。
返回true;
}
返回super.onKeyDown(键code,事件);
}
下面这个链接是关于如何处理返回键事件,写的Android开发自己的详细说明:
Using返回键
I am having two activities A and B. when i click the button in A that will shows B. when i click the Button in B it backs to A. i had set the overridePendingTransition method after the finish() method. it works properly. but in case the current Activity is B. on that time i click the default back button in the device. it shows the right to left transition to show the Activity A.
How i can listen that Default back key on device?
EDIT:
Log.v(TAG, "back pressed");
finish();
overridePendingTransition(R.anim.slide_top_to_bottom, R.anim.hold);
解决方案
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
// do something on back.
return true;
}
return super.onKeyDown(keyCode, event);
}
