Question

我想在使用actionbarsherlock lib实现的Navigationdrawer中的片段中使用listview。问题是listView高度没有缩放到match_parent。它被扩展到listview的一项。我搜索了很多，尝试了类似的问题，并尝试将父布局更改为Relative_layout，Linear_layout和Frame_layout。我没有得到我做错的事。如何缩放listView以获取其余大小的布局。

这就是它在编辑器中的样子

this is how it looks in editor

这就是它在app中的样子。 listView的大小缩放为一个项目。对于更多项目，我必须滚动该空间。

我的主片段布局

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/body_background_green"
android:orientation="vertical"
android:padding="5dp" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginBottom="30dp"
    android:text="@string/farmerlist"
    android:textAppearance="?android:attr/textAppearanceLarge" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="20dp" >

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/farmercode" />

    <AutoCompleteTextView
        android:id="@+id/autoCompleteTextView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:ems="10"
        android:hint="@string/farmercode"
        android:inputType="number" >

        <requestFocus />
    </AutoCompleteTextView>
</LinearLayout>
    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/transparent"
        android:dividerHeight="2dp" >
    </ListView>

</LinearLayout>

这是项目布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

<LinearLayout

        android:layout_height="wrap_content"
        android:text="Code : " />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="code"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</LinearLayout>

<LinearLayout

</LinearLayout>

<LinearLayout

    <TextView

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

    <TextView
        android:id="@+id/textView6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="type"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</LinearLayout>

</LinearLayout>

这是我的活动布局

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:background="@color/body_background_green"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- As the main content view, the view below consumes the entire
     space available using match_parent in both dimensions. -->
<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="6dp"
    android:paddingRight="6dp"
    android:scrollbarStyle="outsideOverlay">
     <FrameLayout
    android:id="@+id/frame_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    </FrameLayout>

</ScrollView>
<!-- android:layout_gravity="left" tells DrawerLayout to treat
     this as a sliding drawer on the left side. The drawer is
     given a fixed width in dp and extends the full height of
     the container. A solid background is used for contrast
     with the content view. -->
<ListView android:id="@+id/left_drawer"
          android:layout_width="250dp"
          android:layout_height="match_parent"
          android:layout_gravity="left"
          android:background="@android:color/white"/>
</android.support.v4.widget.DrawerLayout>

这是我的Sherlockfragment

public class Startcollection extends SherlockFragment {
AutoCompleteTextView auto;
ListView lv;
Fadapter adapter;
ArrayList<String> list;
ArrayAdapter<String> autoadapter;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.startcollectionfrag,
            container, false);
            auto=(AutoCompleteTextView)rootView.findViewById(R.id.autoCompleteTextView1);
    lv=(ListView) rootView.findViewById(R.id.listView1);
    list=new ArrayList<String>();
    for(int i=0;i<Constant.vec_prod.size();i++)
    {
        list.add(Constant.vec_prod.get(i).getCode()
                +" "+Constant.vec_prod.get(i).getFirstname());
    }
    adapter=new      Fadapter(getActivity(),R.layout.listitem,Constant.vec_prod);
    auto.setThreshold(1);
    autoadapter=new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1,list);
    auto.setAdapter(autoadapter);
    lv.setAdapter(adapter);
    return rootView;
}

public class Fadapter extends ArrayAdapter<ProducerModel>
{
    Activity context;
    Vector<PModel> vecprod;
    TextView code,name,type;
    LinearLayout ll;
    public Fadapter(Activity context, int textViewResourceId, Vector<PModel> vecprod) {
        super(context, textViewResourceId,vecprod);
        this.context=context;
        this.vecprod=vecprod;
    }

    public View getView(int position, View view, final ViewGroup parent) {
        LayoutInflater inflater = context.getLayoutInflater();
        View rowView= inflater.inflate(R.layout.listitem, null);
        code=(TextView) rowView.findViewById(R.id.textView2);
        name=(TextView) rowView.findViewById(R.id.textView4);
        type=(TextView) rowView.findViewById(R.id.textView6);
        ll=(LinearLayout) rowView.findViewById(R.id.ll1);
        code.setText(vecprod.get(position).getCode()+"");
        name.setText(vecprod.get(position).getFirstname());
        type.setText(vecprod.get(position).getTypes());
        return rowView;
    }

}
}

Answer 1

对LinearLayout weight使用ListView并试一试：

<ListView
    android:id="@+id/listView1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" 
    android:background="@drawable/transparent"
    android:dividerHeight="2dp" >
</ListView>

发布Activity布局后

更新，问题很明显。这是因为您将ListView放入ScrollView。我认为您的ScrollView没有用，您可以删除它并将layout_height的{{1}}更改为frame_container并尝试一下。

请参阅以下帖子，了解为何不能将match_parent加入ListView：

Answer 2

将主布局的父级Linearlayout更改为相对布局

match_parent不适用于SherlockFragment中listView的layout_height
