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.

Answer 1

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");
