android - Xmlns:android Problem
<p>For Every Layout xml file contains this instruction at First Layout (xmlns:android="http://schemas.android.com/apk/res/android") once is enough or we need to put every Layout in the xml file.
Like this </p>

<pre><code> &lt;LinearLayout 
        xmlns:android="http://schemas.android.com/apk/res/android"
        ------------
        ---------&gt;
        &lt;Textview
           ---------/&gt;
         &lt;LinearLayout 
            xmlns:android="http://schemas.android.com/apk/res/android"
            ------------
            ---------&gt;  
            &lt;ListView
                --------------
                ---------------/&gt;
         &lt;/LinearLayout&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>thanks</p>
