How to make the text fade for seconds

Question

How to make the text fade for only 20 seconds and then disappear when you click the button

This is the code

 public void scoreOpenB(View v) {

        findViewById(R.id.main_mess).setVisibility(View.GONE);

     ((TextView)findViewById(R.id.main_mess)).setText(R.string.btn_closs);
        findViewById(R.id.main_mess).setVisibility(View.VISIBLE );
    }
}

It is not clear from your post what the issue you are having is or perhaps if this is a solution? Please can you you review this? — Innocent Anigbo, Aug 13 '17 at 22:14

You can use AsyncTask to update UI after delay. Try this ;)

    public void scoreOpenB(View v) {

        View updateMe = findViewById(R.id.main_mess);
        updateMe.setVisibility(View.GONE);

        new UpdateUI().execute(updateMe);
    }
}


private class updateUI extends AsyncTask<View, Integer, Long> {
    View toUpdate;

    protected void doInBackground(View view) {
        toUpdate = view;
        try {
            Thread.sleep(20000);
        } catch (InterruptedException ex) {
            Thread.currentThread().interrupt();
        }
    }

    protected void onProgressUpdate(Integer... progress) {
    }

    protected void onPostExecute(Long result) {
        (toUpdate(TextView)).setText(R.string.btn_closs);
        toUpdate.setVisibility(View.VISIBLE);

    }
}
