I have created a roundbutton. I want to display this roundbutton for the number in the count. The count represents the number of button presses. For example if the count equals 2 then 2 roundbutton must appear on the screen. Instead of me having to put each button on the screen and making it invisible at first then visible depending on the count.

roundbutton

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#FF2A2A" />
<corners android:bottomRightRadius="10dp"
    android:bottomLeftRadius="10dp"
    android:topRightRadius="10dp"
    android:topLeftRadius="10dp"/>
</shape>

Make timer and change your image each second, but because that will be a timer...you need to change your image in runnable method, which will be behaving like UI thread.

  • Timer T=new Timer(); T.scheduleAtFixedRate(new TimerTask() { @Override public void run() { myTextView.setText("count="+count); count++; } }, 1000, 1000); – Jevgenij Kononov Jun 19 '18 at 11:33

In your code, after count change you might change back by:

btnBack.setImageResource(R.drawable.ic_camera);

also for change visibility you can use:

View.setVisibility(View.GONE / View.VISIBLE / View.INVISIBLE)
