Here's how you can do that:
您可以这样做：
// Get the parent layout
RelativeLayout parent = (RelativeLayout) findViewById(R.id.parent);
// Create your custom layout
RelativeLayout relativeLayout = new RelativeLayout(this);
// Create LayoutParams for it // Note 200 200 is width, height in pixels
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(200, 200);
// Align bottom-right, and add bottom-margin
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
params.bottomMargin = 100;
relativeLayout.setLayoutParams(params);
relativeLayout.setBackgroundColor(Color.BLUE);
// Add the custom layout to your parent layout
parent.addView(relativeLayout);

you can try this it work in my case:
你可以试试这个它在我的情况下工作：
RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) view.getLayoutParams();
// position on right bottom
rlp.addRule(RelativeLayout.ALIGN_PARENT_LEFT, 0);
rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP,0);
rlp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
