public class MainActivity5 extends Activity { 
	ProgressBar mProgressBar;
	RelativeLayout root_RelativeLayout;
	@Override 
	public void onCreate(Bundle savedInstanceState) {   
		super.onCreate(savedInstanceState);   
		setContentView(R.layout.activity_main5);   
		root_RelativeLayout = (RelativeLayout) findViewById(R.id.root_RelativeLayout); 
		mProgressBar = new ProgressBar(this,null,android.R.attr.progressBarStyleHorizontal);
		mProgressBar.setMax(100);
		mProgressBar.setProgress(40);
		mProgressBar.setProgressDrawable(getResources().getDrawable(R.drawable.progressbar_horizontal_1)); 
		RelativeLayout.LayoutParams relLayoutParams = new RelativeLayout.LayoutParams(400,50);
		relLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
		relLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
		int top = 100;
		int left = 200;
		relLayoutParams.setMargins(left, top, 0, 0);
		root_RelativeLayout.addView(mProgressBar,relLayoutParams);
	}
}
