Android setError("error") not working in Textview

Question

We can set error in Edittext successfully but failed to set in textview. is there any problem?? i tried

((TextView) findViewById(R.id.df)).requestFocus();
((TextView) findViewById(R.id.df)).setSelected(true);
((TextView) findViewById(R.id.df)).setError("akjshbd");

but i am not getting popup for error.

Textview Error

@Anis, this is written in http://developer.android.com/reference/android/widget/TextView.html, that setError(CharSequence error): Sets the right-hand compound drawable of the TextView to the "error" icon and sets an error message that will be displayed in a popup when the TextView has focus. — MysticMagicϡ, Nov 22 '12 at 08:56

Default TextView is NOT focusable. So, you need to set android:focusable="true" and android:focusableInTouchMode="true".

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:text="@string/hello_world" />

And no need to set setSelected(true).

((TextView) findViewById(R.id.df)).requestFocus();
((TextView) findViewById(R.id.df)).setError("akjshbd");

I prefer this solution. Setting the style to @android:style/Widget.EditText is overkill and makes the TextView look like an EditText. – starkej2 Apr 24 '14 at 20:54

This solution is much cleaner than the accepted answer. – Ridcully Apr 13 '15 at 10:51

Actually , you can use the setError for the textView and show its popup .

You just need to use the same style as of the EditText .

Simply add the next attribute for the textView in the xml :

style="@android:style/Widget.EditText"

@AdeelTurk glad you did but could you share how you did so? It could help the community and people here could make it bug-free if there is an issue at all. :) – Sufian Feb 25 '19 at 08:51

hey everyone i was in a rush at that time so couldnt find time to explain , i adopted the same solution given above but whenever you tao on field to look at the error message it activates the keyboard so for me putting android:focusableInTouchMode="true" android:focusable="true" in textview worked like a charm . – Adeel Turk Feb 25 '19 at 09:22
@androiddeveloper and Sufiyan pardon me for the delay #PEACE ;) – Adeel Turk Feb 25 '19 at 09:23
@AdeelTurk Shouldn't it be the opposite? Meaning not focusable? – android developer Feb 25 '19 at 10:42
well! i want to show error when user tap on textview – Adeel Turk Feb 25 '19 at 10:43
yeah kind of!! thats why i said i sorted out my problem :) – Adeel Turk Feb 26 '19 at 05:48

This is the only you need to get expected setError behaviour on the TextView

android:focusable="true"
android:clickable="true"
android:focusableInTouchMode="true"

Snippet: you have to requestFocus(); a view to show the error.

    // Check for a valid email address.
if (TextUtils.isEmpty(mEmail)) {
    mEmailView.setError(getString(R.string.error_field_required));
    focusView = mEmailView;
    cancel = true;
} else if (!mEmail.contains("@")) {
    mEmailView.setError(getString(R.string.error_invalid_email));
    focusView = mEmailView;
    cancel = true;
}

if (cancel) {
    // There was an error; don't attempt login and focus the first
    // form field with an error.
    focusView.requestFocus();
} else {
    // Show a progress spinner, and kick off a background task to
    // perform the user login attempt.
    // showProgress(true);
    // mAuthTask = new UserLoginTask();
    // mAuthTask.execute((Void) null);
    ParseUser.logInInBackground(mEmail, mPassword, new LogInCallback() {

    @Override
    public void done(ParseUser user, ParseException e) {
        finishAndStartCardActivity();
    }
    });
}
