I have a list view connected to a database, showing a all the entries. I want a menu to show up if the user long clicks a item in the listview(database entry), showing options to edit or delete the entry. how can i do this.
Till now, I have tried using a onItemLongClick listener and a toast in it showing the id of the view long clicked.
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
String res = Long.toString(id);
Toast toast = Toast.makeText(this, res, Toast.LENGTH_SHORT);
toast.show();
return true;
}
First you need to register your context menu on list view.
lv = (ListView) findViewById(R.id.list_view);
registerForContextMenu(lv);
Then, just override activity methods.
/**
* MENU
*/
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
if (v.getId()==R.id.list_view) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_list, menu);
}
}
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch(item.getItemId()) {
case R.id.add:
// add stuff here
return true;
case R.id.edit:
// edit stuff here
return true;
case R.id.delete:
// remove stuff here
return true;
default:
return super.onContextItemSelected(item);
}
}
Here is an example of menu_list.xml file (you have to put the file in the res/menu folder).
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/add"
android:icon="@android:drawable/ic_menu_add"
android:title="@string/menu_add" />
<item android:id="@+id/edit"
android:icon="@android:drawable/ic_menu_edit"
android:title="@string/menu_edit" />
<item android:id="@+id/delete"
android:icon="@android:drawable/my_icon_delete"
android:title="@string/menu_delete" />
</menu>
Hope it will help.
