  <pre><code> &lt;LinearLayout
      android:id="@+id/linearLayout1"
      android:layout_width="match_parent"
      android:layout_height="wrap_content" &gt;
  
      &lt;Button
          android:id="@+id/button2"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="Button" /&gt;
  
      &lt;ImageView
          android:id="@+id/imageView1"
          android:layout_width="wrap_content"
          android:layout_height="match_parent"
          android:layout_weight="0.59"
          android:src="@drawable/x_title" /&gt;
  
      &lt;Button
          android:id="@+id/button3"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="Button" /&gt;
  &lt;/LinearLayout&gt;
  
  &lt;LinearLayout
      android:id="@+id/linearLayout_grouplist"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_weight="0.09"
      android:orientation="vertical"
      android:weightSum="1" &gt;
  
      &lt;ListView
          android:id="@+id/listview_grouplist"
          android:layout_width="match_parent"
          android:layout_height="0dp"
          android:layout_weight="1" &gt;
      &lt;/ListView&gt;
  
  &lt;/LinearLayout&gt;
  
  &lt;LinearLayout
      android:id="@+id/linearLayout2"
      android:layout_width="match_parent"
      android:layout_height="wrap_content" &gt;
  
      &lt;Button
          android:id="@+id/button4"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="Button" /&gt;
  
      &lt;TextView
          android:id="@+id/textView1"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_weight="0.39"
          android:text="TextView" /&gt;
  
      &lt;Button
          android:id="@+id/button5"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="Button" /&gt;
    &lt;/LinearLayout&gt;
  &lt;/LinearLayout&gt;`
  </code></pre>
  
  <p>when I try to add items to the list with array adapter, its working fine for me..but its not working for List Adapter. It is crashing. </p>
  
  <pre><code>ListAdapter adapter = new SimpleAdapter(this,
        mylist, 
        R.layout.grouplistlayout, 
        new String[] { "Group Name" }, 
        new int[] { R.id.listview_grouplist });
  
  String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
        "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
        "Linux", "OS/2" };
  
  ArrayAdapter&lt;String&gt; adapter1 = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, values);
  lst_projlist.setAdapter(adapter1);
  </code></pre>
