更改右侧图标样式错误 TextInputLayout

Question

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?.

Answer 1

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

Something like:

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

Answer 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);
