我在EditText上应用OnKeyListener()并且它不在三星Galaxy S3上工作但是在所有其他手机上工作......不知道我做错了什么...

  et = (EditText) findViewById(R.id.editText1); 
  et.setOnKeyListener(new OnKeyListener() {

        @Override
        public boolean onKey(View arg0, int keyCode, KeyEvent arg2) {
            // TODO Auto-generated method stub
            // You can identify which key pressed buy checking keyCode value
            // with KeyEvent.KEYCODE_
            if (keyCode == KeyEvent.KEYCODE_DEL) {
                // this is for backspace
                Log.d("Button Event", "BackSpace Pressed");
                if (et.getSelectionStart() < length + 1) {
                    return true;
                } else {
                    return false;
                }
            }
            return false;
        }

    });

我正在尝试将一个加密的旧脚本恢复生命,但我不是最好的PHP,但是练习使得完美.

我刚解码它并经历安装过程,我得到PHP Notices Undefined变量.
