android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</FrameLayout>
list item layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:id="@+id/info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="15sp"
android:singleLine="true"
android:ellipsize="marquee"
android:scrollHorizontally = "true"
android:maxWidth="200dp"
/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="right"

<ImageButton
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="@null"
android:paddingRight="10dp"
android:paddingLeft="10dp"
/>
</LinearLayout>
</LinearLayout>
In activity
@Override
public void onCreate(Bundle savedInstanceState) {
registerForContextMenu(getListView());
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.context_menu, menu);
}
Why I do not see context menu? What I do wrong? How to get context menu with array adapter and ListActivity. Thanks!

Custom ListView and context menu. How to get it?
回答2:
You need to set the property LongClickable for the first LinearLayout from list item layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:longClickable="true"
