TextInputLayout Error right align
So thanks to Mike's answer I was able to figure out the solution.
I created a custom class:
public class CustomTextInputLayout extends TextInputLayout {
public CustomTextInputLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public void setErrorEnabled(boolean enabled) {
super.setErrorEnabled(enabled);
if (!enabled) {
return;
}
try {
Field errorViewField = TextInputLayout.class.getDeclaredField("mErrorView");
errorViewField.setAccessible(true);
TextView errorView = (TextView) errorViewField.get(this);
if (errorView != null) {
errorView.setGravity(Gravity.RIGHT);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.END;
errorView.setLayoutParams(params);
}
}
catch (Exception e) {
// At least log what went wrong
e.printStackTrace();
}
}
}
Now I simply replaced my TextInputLayout with the CustomTextInputLayout. Works like a charm. Thanks a lot Mike. I wish I could credit you more for this answer.
Here's a hack in Kotlin that doesn't depend on view hierarchy:
class CustomTextInputLayout @JvmOverloads constructor(
context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : TextInputLayout(context, attrs, defStyleAttr) {
override fun setError(errorText: CharSequence?) {
super.setError(errorText)
with(findViewById<TextView>(R.id.textinput_error)) {
// this will work as long as errorView's layout width is
// MATCH_PARENT -- it is, at least now in material:1.2.0-alpha06
textAlignment = TextView.TEXT_ALIGNMENT_VIEW_END
}
}
}
