Why does my android border not display? -



Why does my android border not display? -

border.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" > <solid android:color="#ffffff" /> <stroke android:width="1dip" android:color="#cbcbcb" /> <corners android:radius="7dp" /> </shape>

set background of linearlayout:

<?xml version="1.0" encoding="utf-8"?> <linearlayout android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/border" android:orientation="vertical" > //child command </linearlayout>

if linearlayout has kid control: border display ok. if linearlayout have much kid controls, border can't display. why border not display? how set border in case?

because of line :

android:layout_height="wrap_content"

when linearlayout doesn't have kid wrap_content in android:layout_height cause linearlayout height 0dp , nil gonna show.set size layout , border show up.
