Android Listview不滚动仍然无法正常工作

Question

Good day!

I have tried a lot of other posts on stackoverflow but it didn't work for me, maybe its because I'm new to Android Development.

My problem is as follow:

XML Layout:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/item_detail_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:gravity="center_horizontal"
tools:context=".ItemDetailActivity"
tools:ignore="MergeRootFrame" >

<TextView
    android:layout_width="match_parent"
    android:layout_height="89dp"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:text="Medium Text"
    android:id="@+id/txtDetails"
    android:layout_gravity="center_horizontal|top"
    android:padding="5dp" />

<ListView
    android:id="@+id/list"
    android:layout_width="match_parent"
    android:layout_height="369dp"
    android:layout_gravity="center_horizontal|bottom" />

</FrameLayout>

Preview in Android Studio :

inside the onCreateView:

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) { }

Binding the listview:

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
 final View rootView = inflater.inflate(R.layout.fragment_item_detail,     container, false);


  List<Events> list = Events.getEvents();
  int max = list.size();
  String[] Values = new String[max];
  for (int i = 0; i < max; i++) {

      Events e = list.get(i);
      Values[i] = e.getNaam();
  }

  ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
                                    rootView.getContext(),
                                    android.R.layout.simple_list_item_1, Values);

 listView.setAdapter(arrayAdapter);

 return rootview;

 }

Another point is i can't click a list item wich is strange !

Any ideas or tips? what do i wrong?

Kind Regards, Stefan

Try something like the following.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/item_detail_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center_horizontal"
    tools:context=".ItemDetailActivity"
    tools:ignore="MergeRootFrame" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:id="@+id/linearLayout">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:text="Medium Text"
            android:id="@+id/txtDetails"
            android:layout_gravity="center_horizontal|top"
            android:paddingLeft="5dp"
            android:paddingRight="5dp"
            android:paddingTop="10dp"
            android:paddingBottom="10dp" />

        <ListView
            android:id="@+id/list"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1" />
    </LinearLayout>

</FrameLayout>

<LinearLayout>    
    <ScrollView>
         <ListView ...>

         </listView>
    </ScrollView>
</LinearLayout>

You need to add a LinearLayout around the scrollview, that way the scrollview knows inside what it should scroll. If this doesn't work, replace the ListView with another LinearLayout and add your items to the LinearLayout. I'm not sure if a View is capable of scrolling at all. Try first option first, otherwise try the latter. I know the latter will work for sure since I used the exact same design myself in an app I'm developing.

Answer 4

As already mentioned in the comment, you have to add a ScrollView around your ListView, eg:

<ScrollView>
     <ListView ....>
     </ListView>
</ScrollView>
