android - 最小化键盘按钮不被识别为后退按钮

Question

使用log.d和函数作为：

@Override
public void onBackPressed(){
    Log.d("back","back");
    }
}

看来，最小化键盘的按钮未被识别为后退按钮。是否有一种解决方法可以找到此按钮的 keyID，或者它是否确实存在并且我做错了什么？

Answer 1

Use this method

protected boolean onKeyDown(int keyCode, KeyEvent event) {
     if (keyCode == KeyEvent.KEYCODE_BACK) {
        // do whatever you want to do
        return true;
     }
     return false;
 }

Refer Back and other keys. But if onBackPressed is not working, also try to implement onKeyDown method where you handle keycode for back.
