Why dont my linear layout view gets displayed when i run my app
<p>i have already created my xml file in which 4 layouts are used. now i want a linear layout to be displayed between my 3rd and fourth layout.i have set the width of this new layout to 0dp, for which i want the width to be changed to "wrap content" when my app is launched. </p>

<p>i have tried using the following code</p>

<pre><code>LinearLayout  layout = (LinearLayout)base.findViewById(R.id.layout);    
LinearLayout.LayoutParams params = new  LinearLayout.LayoutParams( 
            LinearLayout.LayoutParams.WRAP_CONTENT,  LinearLayout.LayoutParams.WRAP_CONTENT); 
    Log.w(TAG, "layout " +layout);
    layout.setLayoutParams(params);
</code></pre>

<p>following is my layout in xml file</p>

<pre><code>   &lt;LinearLayout android:layout_width="fill_parent" android:id="@+id/layout"
android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp" android:layout_height="0dp"
    &gt;
    &lt;Button android:id="@+id/button1" android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"   android:layout_width="wrap_content"
        android:text="NO" 
        android:layout_marginLeft="50dp" 
        android:layout_marginTop="64dp"&gt;&lt;/Button&gt;
    &lt;Button android:id="@+id/button2"
        android:layout_alignParentRight="true" android:layout_height="wrap_content"
        android:layout_width="wrap_content" android:text="YES"

        android:layout_marginRight="50dp" 
        android:layout_marginTop="64dp"&gt;&lt;/Button&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>but the layout value takes here as null.. Can anyone tell me how this can be solved..???
Thanks in advance..</p>
