Answer 1

Dont use setBackgroundDrawable but use::

@Override
   public void onClick(View v) {
    TextView txt = (TextView) findViewById(R.id.txt);
    txt.setBackgroundResource(R.drawable.textview_logo);

    Toast.makeText(getBaseContext(), "this test is ok!", Toast.LENGTH_SHORT).show();
   }
});

Make sure textview_logo are stay in drawable folder

for set background :

txt.setBackgroundColor(Color.RED);

You can set any color using this:

txt.setBackgroundColor(Color.parseColor("#BABABA")); // set any custom color as background color 

or

txt.setBackgroundColor(Color.RED); // set default RED color as background color
