Android EditText聚焦时hint消失的简单代码

mInfo = (EditText) findViewById(R.id.fabu_info);

mInfo.setOnFocusChangeListener(new OnFocusChangeListener() {

public void onFocusChange(View v, boolean hasFocus) {

EditText _v=(EditText)v;

if (!hasFocus) {// 失去焦点

_v.setHint(_v.getTag().toString());

} else {

String hint=_v.getHint().toString();

_v.setTag(hint);

_v.setHint("");

}

}

});
