TextInputLayout error text padding

问题

I am using TextInputLayout with AppCompatEditText having a custom xml shape based background for AppCompatEditText. Whenever i set some error , the error line starts from beginning of layout. Is there any way to give padding to that error line.

回答1:

You can reference error TextView by using:

TextView textView = (TextView) inputLayout.findViewById(android.support.design.R.id
            .textinput_error);

Then you can get its layout params to work with.

<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
    android:id="@+id/tx_in_username"
    android:errorEnabled="true"
    android:layout_marginLeft="@dimen/margin_LEFT_RIGHT"
    android:layout_marginRight="@dimen/margin_LEFT_RIGHT"
android:layout_height="wrap_content">
<EditText
    android:layout_width="match_parent"
    android:layout_marginTop="10dp"
    android:layout_height="36sp"
    android:hint="Username"
    />
