为什么我的listView不可见？

Question

我有我的片段和我自己的适配器创建一个ListView创建自己的布局，对于ListView但它不显示任何

的XML为我的ListView布局：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/LinearLayout1" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:gravity="fill|right" > 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" > 

     <TextView 
      android:id="@+id/textView_listViewText" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="Medium Text" 
      android:textAppearance="?android:attr/textAppearanceMedium" /> 
    </LinearLayout> 

    <LinearLayout 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" > 

     <ImageView 
      android:id="@+id/imageView_adressList1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:src="@drawable/bronze_pin_level" /> 

     <ImageView 
      android:id="@+id/imageView_adressList2" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:src="@drawable/bronze_pin_level" /> 

     <ImageView 
      android:id="@+id/imageView_adressList3" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:src="@drawable/bronze_pin_level" /> 

    </LinearLayout> 

</LinearLayout> 

的XML为我的ListView

<?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:orientation="vertical" > 

<ListView 
    android:id="@+id/listView_adressList" 
    android:layout_width="match_parent" 
    android:layout_height="0dp" 
    android:layout_weight="2.25" > 
</ListView> 

<ImageView 
    android:id="@+id/imageView_adressList1" 
    android:layout_width="match_parent" 
    android:layout_height="43dp" 
    android:src="@drawable/bottom_me" /> 

片段代码：

public class FragList extends Fragment { 

ListView listView; 
View myFragmentView; 
List<String> adressList; 

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

    myFragmentView = inflater.inflate(R.layout.frag_list, container, false); 

    listView = (ListView) myFragmentView 
      .findViewById(R.id.listView_adressList); 


    adressList = new ArrayList<String>(); 

    adressList.add("Marvin"); 
    adressList.add("Markus"); 
    adressList.add("Bob"); 


    ArrayAdapter<String> adapter = new MyAdapter(getActivity(), 
      R.layout.adress_list_layout, adressList); 

    listView.setAdapter(adapter); 
    return myFragmentView; 

} 

public class MyAdapter extends ArrayAdapter<String>{ 

    private List<String> values; 
    ImageView btn1, btn2, btn3; 
    Context cont; 
    int layoutID; 

    public MyAdapter(Context context, int resource, List<String> values) { 
     super(context, resource); 
     this.values = values; 
     this.cont = context; 
     this.layoutID = resource; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     LayoutInflater inflater = (LayoutInflater) this.cont 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     View rowView = inflater.inflate(this.layoutID, 
       parent, false); 

     TextView tv1 = (TextView) rowView 
       .findViewById(R.id.textView_listViewText); 
     tv1.setText(values.get(position)); 

     btn1 = (ImageView) rowView 
       .findViewById(R.id.imageView_adressList1); 

     btn2 = (ImageView) rowView 
       .findViewById(R.id.imageView_adressList2); 

     btn3 = (ImageView) rowView 
       .findViewById(R.id.imageView_adressList3); 

     return rowView; 

    } 

    } 
} 

的问题是，列表视图未显示在屏幕上。这只是一个白色的屏幕。 显然我做的事情很错，但我不知道是什么。

Answer 1

尝试用

视图= View.inflate（续，R.layout.name_of_your_listView_layout，NULL）;

，而不是

View rowView = inflater.inflate(this.layoutID, 
      parent, false); 

Answer 2

变化的高度值，然后再试一次......
