如何在TextWatcher方法上下文中获取视图？

Question

我有一个处理程序是一个TextWatcher,我不知道如何获得View更改文本.

这是我的处理程序:

TextWatcher handler = new TextWatcher() {

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

    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        oldText = s.toString();
    }

    @Override
    public void afterTextChanged(Editable s) {
        //v.setText("afterTextChanged");
    }
};

请注意注释部分,这是我想要的,View从EditText触发事件的那个开始,在文本更改后更改文本.

我如何.setText()在afterTextChanged事件中达到此方法？(就像查看的onClick事件一样v)

Answer 1

public static class MyTextWatcher implements TextWatcher {

    private EditText mEditText;

    public MyTextWatcher(EditText editText) {
        mEditText = editText;
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        oldText = mEditText.toString();
    }
    ....
}

添加它:

    mFirstEditText.addTextChangedListener(new MyTextWatcher(mFirstEditText));
