Question

我正在使用EditText的植被,我正在用EditText的<代码>setError()方法验证该植被,并且正确验证。

But I have an button in the same screen that redirects to another activity. And when I press back button and come back to the screen the validation still appears.

So on the activity OnPause event I want to remove the validation of the EditText. How is it possible.

Answer 1

protected void onPause () {
    TextView textView = ...; // fetch it as appropriate
    textView.setError(null);
}

由于文件提到:

如果错误无效,错误信息和icon将被清除。

Answer 2

In Kotlin:

editText.error = null

Kotlin Extension Function:

为了使之更易读,你可以增加这一延期职能。

fun EditText.clearError() {
    error = null
}

In Java:

editText.setError(null);

Answer 3

You can also do it using following :

protected void onPause () {    
    mEditText.setError(null);//removes error
    mEditText.clearFocus();    //clear focus from edittext
}

Answer 4

仅带.setError(null),到EditText末。

mEditText.setError(null);

Answer 5

}
