Can I set default button is clicked or selected in android?

Question

I want to do something like when I start the activity, "button A" is clicked ( or selected) as default , a String will be shown immediately in the textview. And there is another Button, "button B". When I click on it, "button A" isSelected set to be false and "button B" isSelected set to be true, show required "button b" text.

I am already done the button change text when isSelected(), I just cannot set one of it as default "clicked" or "selected", can anyone help?

Have you tried with `myButton.performClick`? – zozelfelfo Sep 08 '15 at 09:13 — zozelfelfo, Sep 08 '15 at 09:13

ya, I have set one of the button as true and the others as false when I " click" it. I want to do is set one of it is true as default before i clicked it or when i enter the activity. – kris ho Sep 08 '15 at 09:32
Then you could put 'mButton.setSelected(true)' in your 'onCreate()' where your activity is created. – Joel Min Sep 08 '15 at 09:44

Have you tried [ColorStateList](http://developer.android.com/guide/topics/resources/color-list-resource.html) and checked state? – Andrey Arzhannikov Sep 08 '15 at 09:38
Yes, I can change the text and color when I clicked it, but not default selected. – kris ho Sep 08 '15 at 09:44

You can create a OnClick function of that button, and call it in onCreate().
