    text
    copied!<p>I have a two layouts files in my app. Also I have Activity extends ListActivity. Every item of this activity looks consider item.xml layout file. I am trying to get context menu when make long presss on item, but I don't see it.</p> <p>In my activity I trying to registerForContextMenu(getListView()) and override two methods</p> <pre><code> @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Bundle bundle = this.getIntent().getExtras(); registerForContextMenu(getListView()); new PopulateAdapterTask().execute(ACTION_SELECT); } @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.context_menu, menu); } @Override public boolean onContextItemSelected(MenuItem item) { AdapterView.AdapterContextMenuInfo info; try { info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo(); } catch (ClassCastException e) { return false; } long id = getListAdapter().getItemId(info.position); Log.d(TAG, "id = " + id); return true; } </code></pre> <p>Main.xml</p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"&gt; &lt;TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/&gt; &lt;FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"&gt; &lt;ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" /&gt; &lt;/FrameLayout&gt; &lt;/LinearLayout&gt; &lt;/TabHost&gt; </code></pre> <p>Item.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" &gt; &lt;ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt; &lt;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" /&gt; &lt;LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="right" &gt; &lt;ImageButton android:id="@+id/button" android:layout_width="wrap_content" android:layout_height="fill_parent" android:background="@null" android:paddingRight="10dp" android:paddingLeft="10dp" /&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; </code></pre> <p>All this doesn't work. Maybe the reason is in LinearLayout? I also find similar topic <a href="https://stackoverflow.com/questions/2890529/android-context-menu-doesnt-show-up-for-listview-with-members-defined-by-linear">Android: Context menu doesn&#39;t show up for ListView with members defined by LinearLayout?</a> but I have more complicated list item.</p> <p>How to get context menu in my case? </p> <p>Also in my activity I have inner class extends ArrayAdapter. In this class in getView method I can set OnCreateContextMenuListener on every View, after that context menu is appears, but I don't know how to handle items clicks. If I am trying to do this in method onContextItemSelected, item.getMenuInfo() object always is null and i can't to get some information from it.</p> <pre><code>private class ChannelAdapter extends ArrayAdapter&lt;Channel&gt; { private List&lt;Channel&gt; channels; public ChannelAdapter(Context context, int textViewResourceId, List&lt;Channel&gt; objects) { super(context, textViewResourceId, objects); this.channels = objects; } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.station_item, null); } v.setOnCreateContextMenuListener(new View.OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.context_menu, menu); } }); </code></pre> <p>Thanks. Hope for your help.</p>
