我创建了一个扩展BaseAdapter的自定义适配器。使用这个自定义适配器我想填充我的listview。当我执行代码时,我的适配器的getView方法不会被调用。我已经看过很多帖子,但没有一个帮助过。我的适配器看起来像这样:

public class EditableLayersAdapter extends BaseAdapter {

private List<EditLayerModel> editLayersList;
private BaseActivity baseActivity;

public EditableLayersAdapter(BaseActivity baseActivity) {
    this.baseActivity = baseActivity;
    this.editLayersList = ((HomeActivity) baseActivity).getEditGraphicsLayers();


}

@Override
public int getCount() {

    return editLayersList.size();
}

@Override
public Object getItem(int position) {

    return editLayersList.get(position);
}

@Override
public long getItemId(int position) {

    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if(convertView==null){
        convertView = baseActivity.getLayoutInflater().inflate(R.layout.edit_mode_editable_layers_list_item, null); 
    }


    return convertView;
}

}

我在列表视图中想要的自定义列表项如下所示:

<?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="horizontal" >

    <RadioButton
        android:id="@+id/edit_mode_list_item_radio_button"
         android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

</LinearLayout>

我在main.xml中添加了listview,如下所示:

 <ListView
        android:id="@+id/home_activity_left_toolbar_editable_layers_listView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/home_activity_left_toolbar_editable_layers_caption" >
    </ListView>

我已经将适配器设置为listview,如下所示:

  editLayersListView = (ListView)editModeLeftToolbarView.findViewById(R.id.home_activity_left_toolbar_editable_layers_listView);

    editLayersListView.setAdapter(new EditableLayersAdapter(baseActivity));

请告诉我,由于getCount被调用而不是getView方法,我做错了什么。
