  1. POUsing OnItemLongClick Listeners with a ListView
    text
    copied!<p>I have a <code>ListView</code> which contains entries given by layout file <strong>entry.xml</strong> I want to start with the <code>ImageView</code> visibility set to <code>View.GONE</code> and <code>onItemLongClick</code> change that to <code>View.VISIBLE</code>. The <code>ListView</code> entry that is long clicked would remain highlighted.</p> <p>I then want to add an <code>onClickListener</code> to the <code>ImageView</code> (whilst its visible) so that the clicked <code>ListView</code> entry can be deleted by tapping the image.</p> <p>There also needs to be a second <code>OnClickListener</code> on the <code>ListView</code> entry so that if it has been long clicked and highlighted this can be undone by (short)clicking on the entry. This would restore the <code>ImageView</code> back to <code>View.GONE</code>.</p> <p><strong>How can I achieve this?</strong></p> <hr> <p><strong>listview.xml</strong></p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" &gt; &lt;ListView android:id="@+id/list" android:layout_width="match_parent" android:layout_height="wrap_content"&gt; &lt;/ListView&gt; &lt;/LinearLayout&gt; </code></pre> <p><strong>entry.xml</strong></p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="8dp" &gt; &lt;ImageView android:id="@+id/entry_deleteicon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:adjustViewBounds="true" android:baselineAlignBottom="false" android:maxHeight="40dp" android:maxWidth="45dp" android:src="@drawable/delete" android:visibility="gone" /&gt; &lt;TextView android:id="@+id/entry_name" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="left" android:text="text" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p><strong>My Custom Adapter</strong></p> <pre><code>private class SaveAdapter extends ArrayAdapter&lt;String&gt; { private int resourceId; private SaveHolder[] holder; public SaveAdapter(Context context, int resource) { super(context, resource); this.resourceId=resource; this.holder = new SaveHolder[5]; } @Override public int getCount() { return 5; } @Override public View getView(final int position, View row, ViewGroup parent) { holder[position] = null; if(row==null){ LayoutInflater inflater = getActivity().getLayoutInflater(); row = inflater.inflate(resourceId, parent, false); holder[position] = new SaveHolder(); holder[position].textName = (TextView) row.findViewById(R.id.entry_name); holder[position].iconDelete = (ImageView) row.findViewById(R.id.entry_deleteicon); row.setTag(holder[position]); }else{ holder[position] = (SaveHolder) row.getTag(); } holder[position].textName.setText("name"); return row; } } static class SaveHolder{ TextView textName; ImageView iconDelete; } </code></pre>
