获得listview中的edittext文字

这周写应用的时候遇到一个问题，就是在listview中的edittext可以输入，但不能获得到edittext中输入的文字。解决的方法是给edittext添加TextWatcher监听事件，并在其中让edittext在输入时通过调用dispatchKeyEvent()方法一直获得焦点，最后在setOnKeyListener()中获得edittext输入的文字。

示例代码如下（代码全部写在adapter中）：

private boolean programmaticalTextChange = false;

 private KeyEvent UnknownKey = new KeyEvent(KeyEvent.ACTION_DOWN,
             KeyEvent.KEYCODE_UNKNOWN);

  holder.groupPwd.setOnKeyListener(new OnKeyListener()
  {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event)
            {
             currentPwd=((EditText) v).getText().toString();
                return false;
            }
        });
    holder.groupPwd.addTextChangedListener(new MyTextWatcher(holder.groupPwd));

    public class MyTextWatcher implements TextWatcher
    {
        private EditText editText;

        public MyTextWatcher(EditText editText)
        {
            this.editText = editText;
        }

        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub

        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before,
                int count) {
            if (!programmaticalTextChange)
                editText.dispatchKeyEvent(UnknownKey);
        }
    }
