Question

我知道这些帖子中有几十个，但即使经过数小时的搜索和尝试不同的解决方案，我也无法使我的列表视图发挥作用。

ListView位于一个片段中，该片段也包含TextView，这也是它不是ListFragment的原因。此片段位于包含Fragment作为Framelayout和Button的Activity中。

ListView正在填充数据，但点击其中一个项目没有任何反应。

活动

public class TurnOnHeadbandActivity extends AppCompatActivity {

    private MuseManagerAndroid manager = null;
    private final Handler handler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.turn_on_headband_activity);

        // XX this must come before other libmuse API calls; it loads the
        // library.
        manager = MuseManagerAndroid.getInstance();
        manager.setContext(this);
        manager.startListening();

        handler.post(tickUi);
    }

    private final Runnable tickUi = new Runnable() {
        @Override
        public void run() {
            List<Muse> pairedMuses = manager.getMuses();
            if (pairedMuses.size() >= 1) {
                Fragment connectedFragment = new TurnOnHeadbandConnectedFragment();
                PairedMuses pairedMusesObject = new PairedMuses(pairedMuses);
                Bundle args = new Bundle();
                args.putSerializable("pairedMuses", pairedMusesObject);
                connectedFragment.setArguments(args);
                FragmentManager fragmentManager = getSupportFragmentManager();
                FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                fragmentTransaction.replace(R.id.turnOnFragment, connectedFragment);
                fragmentTransaction.commit();
            }
            handler.postDelayed(tickUi, 1000 / 60);
        }
    };
}

XML for Activity

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/nightsky">
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="2">
    </LinearLayout>
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="2"
        android:id="@+id/turnOnFragment"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="3">
    </LinearLayout>
    <Button
        android:layout_width="match_parent"

        android:background="@drawable/faqbutton"
        android:layout_margin="10dp"
        android:textColor="@color/textColor"
        android:text="FAQ"/>
</LinearLayout>

片段

public class TurnOnHeadbandConnectedFragment extends Fragment implements OnItemClickListener {

    private ListView museListView;

    public TurnOnHeadbandConnectedFragment() {
        // Required empty public constructor
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View rootView = inflater.inflate(R.layout.turn_on_headband_connected_fragment, container, false);

        Bundle bundle = getArguments();
        PairedMuses pairedMuses = (PairedMuses)bundle.getSerializable("pairedMuses");

         // Fetch the names and MacAddresses of connected muses and store them in string array
         int musesAmount = pairedMuses.getPairedMuses().size();
         String[] musesMacAddresses = new String[musesAmount];
         for (int i = 0; i < musesAmount; i++) {
             musesMacAddresses[i] = String.valueOf(pairedMuses.getPairedMuses().get(i).getName().concat(pairedMuses.getPairedMuses().get(i).getMacAddress()));
         }

         museListView = (ListView) rootView.findViewById(R.id.museListView);
         ArrayAdapter<String> listViewAdapter = new ArrayAdapter<>(getActivity(), R.layout.listview_item, musesMacAddresses);
         museListView.setAdapter(listViewAdapter);
         museListView.setOnItemClickListener(this);

         return rootView;
     }

     @Override
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
         Intent intent = new Intent(getActivity(), Activity.class);
         intent.putExtra("id", id);
         startActivity(intent);
     }
 }

片段的XML

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:layout_margin="10dp"
    tools:context="com.musesleep.musesleep.TurnOnHeadbandConnectedFragment"
    android:descendantFocusability="blocksDescendants">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textStyle="bold"
        android:gravity="center"
        android:textColor="@color/textColor"
        android:text="Select your headband from the list:"/>
    <ListView
        android:id="@+id/museListView"
        android:layout_marginTop="5dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:focusable="false"
        android:focusableInTouchMode="false"/>
</LinearLayout>

自定义ListView项目的XML

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:padding="5dp"
    android:background="#40D3D3D3"
    android:gravity="center_vertical"
    android:textColor="@color/textColor"/>

ListView onItemClickListener在片段内不起作用
