how to set layout margin programmatically in android

LinearLayout ll = new LinearLayout(this); ll.setOrientation(LinearLayout.VERTICAL); LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); layoutParams.setMargins(30, 20, 30, 0); Button okButton=new Button(this); okButton.setText("some text"); ll.addView(okButton, layoutParams);

int sizeInDP = 16; int marginInDp = (int) TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, sizeInDP, getResources() .getDisplayMetrics()); setMargins(view, sizeInDP, sizeInDP, sizeInDP, sizeInDP); void setMargins (View view, int left, int top, int right, int bottom) { if (view.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) { ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams(); p.setMargins(left, top, right, bottom); view.requestLayout(); } }

ViewGroup.LayoutParams p = this.getLayoutParams();
    if (p instanceof LinearLayout.LayoutParams) {
        LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams)p;
        if (_default) lp.setMargins(mc.oml, mc.omt, mc.omr, mc.omb);
        else lp.setMargins(mc.ml, mc.mt, mc.mr, mc.mb);
        this.setLayoutParams(lp);
    }
    else if (p instanceof RelativeLayout.LayoutParams) {
        RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams)p;
        if (_default) lp.setMargins(mc.oml, mc.omt, mc.omr, mc.omb);
        else lp.setMargins(mc.ml, mc.mt, mc.mr, mc.mb);
        this.setLayoutParams(lp);
    }
    else if (p instanceof TableRow.LayoutParams) {
        TableRow.LayoutParams lp = (TableRow.LayoutParams)p;
        if (_default) lp.setMargins(mc.oml, mc.omt, mc.omr, mc.omb);
        else lp.setMargins(mc.ml, mc.mt, mc.mr, mc.mb);
        this.setLayoutParams(lp);
    }
}
