I have a custom Button view. Where I want to get the current text from attributes, modify it and show it.

public class GreenRoundedButton extends AppCompatButton {

public GreenRoundedButton(Context context, AttributeSet attrs) {
    super(context, attrs);

    TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.GreenRoundedButton);
    CharSequence t = a.getText(R.styleable.GreenRoundedButton_android_text);
    a.recycle();

    this.setText("something  else");
}

Currently, I'm able to get the android:text attribute (SO answer) but I cannot reassign to any other value.

Is there a different way to do this than setText()?

I am not exactly sure of what you're trying to achieve here. Do you want to modify the text in the attributes? Or do you want to assign it as the text of your button? – papafe Feb 20 '18 at 14:38

and whats wrong with `TextView#setText()` method? – pskink Feb 20 '18 at 14:43
@pskink it does not work – kike Feb 20 '18 at 14:44
@markusian any of them would work for me – kike Feb 20 '18 at 14:46
@kike So, `setText(t)` does not work? What do you get? – papafe Feb 20 '18 at 14:47
It does nothing. The Button keeps the android:text attribute – kike Feb 20 '18 at 14:50
My apologies. The error was in another part of the code, TextView#setText() works perfect. – kike Feb 20 '18 at 14:54
