How to set the width of a layout in Android?

Question

Is there Any way to set the width of the Layout.

Because most of the time it doesn't work?

Answer 1

<WhateverLayout ... android:layout_width='xxxdip' />

Answer 2

Try adding the layout_width or width attributes to your layout. Example:

<LinearLayout android:layout_width="100dip" android:layout_height="100dip" />

Answer 3

If you're doing it the XML way you'd use the layout_width attribute:

<LinearLayout
    android:layout_width ="100dp"
    android:layout_height="wrap_content" />

If you're doing it programatically you'd use the LayoutParams:

LinearLayour ll = new LinearLayout(this);
parentView.addView(ll, new LinearLayout.LayoutParams(100, LayoutParams.WRAP_CONTENT));
