how to set padding or margin to linear layout?

Question

I have a linear layout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_menu"
android:layout_width="fill_parent"
android:layout_height="70px"
android:layout_alignParentBottom="true"
android:background="@drawable/footer_bar"
android:gravity="center" >
</LinearLayout>

When i set condition

if (constant.getscreenresolution() >= 800) {
    //i want to make it height * 2
}

So how to set the layout params?

For padding:

LinearLayout mLayout = (LinearLayout)findViewById(R.id.layout_menu);
mLayout.setPadding(left, top, right, bottom);

Alan, You should use RelativeLayout params instead of LinearLayout params – yeahdixon Mar 11 '15 at 20:02

You shouldn't be doing this. First you're using pixels (px) instead of device independent pixels (dp) Doing things like this create UIs that only work for specific device screen configurations. You need to learn how Android addresses the variations in screen densities so that your app is screen density independent. Start here:

Add Margin to Linear Layout :-

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
     LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

layoutParams.setMargins(30, 20, 30, 0);
