我有一个显示项目列表的对话框,我需要能够编辑/删除此列表中的项目,所以我放了一个上下文菜单,所以当用户长按一个项目时,他们可以选择他们想要做什么(编辑或删除项目)。
问题是onContextItemSelected
选择上下文菜单中的项目时永远不会被调用。
我检查了创建对话框片段的活动是否正在获取回调,但那也不是,为什么它没有被调用?你不能在对话框中做一个上下文菜单吗?
public class TypesDialogList extends DialogFragment implements LoaderManager.LoaderCallbacks<Cursor>,OnItemClickListener,OnCreateContextMenuListener{
ListView lv;
SimpleCursorAdapter mAdapter;
private int EDIT_TYPE = 1;
private int DELETE_TYPE = 2;
OnEditType mType;
public Dialog onCreateDialog(Bundle state){
final View v = getActivity().getLayoutInflater().inflate(R.layout.layer_dialog_layout, null, false);
lv = (ListView)v.findViewById(R.id.listView1);
lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
lv.setOnItemClickListener(this);
lv.setOnCreateContextMenuListener(this);
return new AlertDialog.Builder(getActivity()).setView(v).setPositiveButton("Add Type", new OnClickListener(){
public void onClick(DialogInterface dialog, int which) {
}
}).setTitle("Type's").create();
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo){
super.onCreateContextMenu(menu, v, menuInfo);
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo;
long id = info.id;
if(id > 3){
menu.setHeaderTitle("Type Menu");
menu.add(Menu.NONE, EDIT_TYPE, 1, "Edit");
menu.add(Menu.NONE, DELETE_TYPE, 2, "Delete");
}else{
Toast.makeText(getActivity(),"Cannot edit type",Toast.LENGTH_SHORT).show();
}
}
@Override
public boolean onContextItemSelected(MenuItem item) {
super.onContextItemSelected(item);
AdapterView.AdapterContextMenuInfo oMenuInfo = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
long id = oMenuInfo.id;
if(item.getItemId() == EDIT_TYPE){
}else if(item.getItemId() == DELETE_TYPE){
}
return true;
}
}
