Android EditText得到和失去焦点、内容变化的监听

EditText editText= (EditText) findViewById(R.id.editText);
    //得到和失去焦点的监听
    editText.setOnFocusChangeListener(new android.view.View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    // 此处为得到焦点时的处理内容
                } else {
                    // 此处为失去焦点时的处理内容
                }
            }
        });
     //内容变化的监听
    editText.addTextChangedListener(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) {
        // TODO Auto-generated method stub

    }

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

    }
});
