How to add a view programmatically to RelativeLayout?

Firstly, you should give an id to your RelativeLayout let say relativeLayout1.

RelativeLayout mainLayout = (RelativeLayout) findViewById(R.id.relativeLayout1);
TextView mTextView = new TextView(context);
mTextView.setText("Dynamic TextView");
mTextView.setId(111);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
params.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
mainLayout.addView(mTextView, params);

Heres an example to get you started, fill in the rest as applicable:

TextView tv = new TextView(mContext);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
    ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
params.leftMargin = 107
...
mRelativeLayout.addView(tv, params);
