这可能是一个重复的问题，但我查看了很多SO问题，但没有找到任何帮助。ActionBar 2个选项卡，每个选项卡中的列表，onClick并不总是触发
我有一个应用程序使用ActionBar有2个选项卡。每个都是一个ListFragment，我无法选择它们上的任何项目。他们会填充很好，但onListItemClick只是不会触发。如果我将setOnItemClickListener直接用于ListView，它也不会触发。但是，如果我只是扩展Fragment而不是ListFragment，如果我将onClickListener附加到每行，那么onClick将会触发。但它会允许多行可点击，这不是我想要发生的事情。任何人都可以帮我弄清楚我做错了什么吗？提前致谢。
这是我的MainActivity：
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the action bar
Drawable drawable = getResources().getDrawable(R.drawable.action_bar);
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(drawable);
bar.addTab(bar.newTab().setText("Tab 1").setTabListener(new TabHandler()));
bar.addTab(bar.newTab().setText("Tab 2").setTabListener(new TabHandler()));
bar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_USE_LOGO);
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setDisplayShowHomeEnabled(true);
bar.setDisplayHomeAsUpEnabled(true);
bar.setDisplayShowTitleEnabled(false);
}
}
这是我的TabHandler：
public class TabHandler implements ActionBar.TabListener {
public Fragment mFragment;
public TabHandler() { }
@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
switch (tab.getPosition()) {
case 0:
if(mFragment == null) {
mFragment = new ListFragmentA();
fragmentTransaction.add(android.R.id.content, mFragment, null);
}
else {
fragmentTransaction.show(mFragment); //Looking into detach and attach as well
}
break;
case 1:
if(mFragment == null) {
mFragment = new ListFragmentB();
fragmentTransaction.add(android.R.id.content, mFragment, null);
}
else {
fragmentTransaction.show(mFragment);
}
break;
default:
break;
}
}
@Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
if (mFragment != null) {
mFragment.getFragmentManager().popBackStackImmediate();
fragmentTransaction.hide(mFragment);
}
}
@Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
mFragment.getFragmentManager().popBackStackImmediate();
}
}
这是我的片段之一的一个示例：
public class ListFragmentA extends ListFragment {
MyCustomAdapter myCustomAdapter;
ListView myListView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.my_list_background,container,false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if(getActivity() != null) {
myListView = (ListView)getActivity().findViewById(android.R.id.list);
if(myListView != null) {
CrudService itemService = new CrudService<TestItem>(TestItem.class);
ArrayList<TestItem> myItems = (ArrayList<TestItem>) itemService.FindAll();
myCustomAdapter = new MyCustomAdapter(getActivity(), myItems);
myListView.setAdapter(myCustomAdapter);
myListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
myListView.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Log.i("ListFragmentA", "MyListView onItemClick");
}
});
}
}
}
//This isn't getting fired
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
Log.i("ListFragmentA", "onListItemClick at position " + position);
}
public class MyCustomAdapter extends ArrayAdapter<TestItem> {
Context mContext;
ArrayList<TestItem> mItems;
public MyCustomAdapter(Context context, ArrayList<TestItem> items) {
super(context, android.R.id.list, items);
mContext = context;
mItems = items;
}
public int getCount() {
return mItems.size();
}
public TestItem getItem(int position) {
return mItems.get(position);
}
public long getItemId(int position) {
return mItems.get(position).getId();
}
public View getView(final int position, View convertView, ViewGroup arg2) {
View rowView = convertView;
if(rowView == null) {
LayoutInflater inflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.single_item, null);
TestItemViewHolder viewHolder = new TestItemViewHolder();
viewHolder.Name = (TextView)rowView.findViewById(R.id.txt_TestItem_Name);
//I have a few more things
rowView.setTag(viewHolder);
}
TestItemListViewHolder holder = (TestItemListViewHolder)rowView.getTag();
TestItem gottenItem = getItem(position);
holder.Name.setText(gottenItem.getName());
//I have a few more things
//However, this will fire if not a ListFragment
rowView.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.i("ListFragmentA", "RowView onClick at position " + position);
}
});
return rowView;
}
}
}
下面是一个例子我的“my_list_background”xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/Tab_Layout_A"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:padding="5dp"
android:background="@color/white">

android:layout_marginRight="11dip"

<!--I have omitted the other columns-->

和我的 “single_item” XML
