setBackgroundDrawable is not changing the LayoutBackground

I have seen several instances of this question on here and the provided solutions dont seem to work.

My goal : Update the background of my LinearLayout depending on what color i get back from a database query.

What I have so far:

if(teamc=="black"){
    drawable = this.getResources().getDrawable(R.drawable.blackbackground);
    Toast.makeText(TeamActivity.this,teamc, Toast.LENGTH_LONG).show();
    teamColor.setBackgroundDrawable(drawable);
    }

Team color is defined as

teamColor = (LinearLayout) findViewById(R.id.teamcolor);

What is happening is that the Toast is appearing just fine but the background is not changing.

Any help would be appreciated.

It is really strange if Toast is working but background is not changing.

Try using teamc.equals("black"){}

or

teamColor.setBackgroundResource(R.drawable.blackbackground);

Are you sure that that toast is showing and not other toast? Because you try to check a String if it's equal to another String by using == operator and that is wrong.

You have to use .equals() method to make a comparison between two Objects.
