Change style of the right icon error TextInputLayout

问题

I want to change the style of the right icon error (the image with ! sign) in a TextInputLayout but I don't find how.

It is possible?.

回答1:

With the Material Component Library just use the app:errorIconDrawable attribute.

Something like:

<com.google.android.material.textfield.TextInputLayout
    app:errorIconDrawable="@drawable/..."
    ../>

回答2:

To do this in your Java class, you can do something like this:

// initialize your drawable object
Drawable myErrorDrawable = getResources().getDrawable(R.drawable.my_error_drawable);

// set the dimension/bounds
myErrorDrawable.setBounds(0, 0, myErrorDrawable.getIntrinsicWidth(), myErrorDrawable.getIntrinsicHeight());

// attach the drawable to your EditText.
editText.setError("An error occured", myErrorDrawable);
