There you will find example and tutorial about your questuion

And also you can set action bar background like this.

private void setActionBar() {
        getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        getSupportActionBar().setCustomView(R.layout.header_actionbar);
        getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.actionbar_blue)));
        TextView tvHeader = (TextView) findViewById(R.id.tv_title_header_actionbar);
        TextView tvSubheader = (TextView) findViewById(R.id.tv_subtitle_header_actionbar);
        tvSubheader.setVisibility(View.GONE);
    }

call setActionBar() in your oncreate().
