我试图了解如何使用 listfragments 和自定义适配器。所以我构建了这个小例子,我想知道在哪里可以将列表视图的分隔符设置为空。
我发现了不同的方法: - android:dividerHeight="1dip" - android:divider="@android:color/transparent" 但我没有带有 listview 的 XML 布局
我还看到了类似 listview.setDivider(null) 的东西,但是由于使用了 listfragments,我不知道在我的代码中哪里可以使用该方法。
我的代码:
listview_item_row.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<ImageView
android:id="@+id/ivCountry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher"
android:layout_weight="1"/>
<TextView
android:id="@+id/tvCountry"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:text="TextView"
android:layout_weight="4" />
</LinearLayout>
CountryList 类
public class CountryList extends ListFragment {
Country[] countries2 = new Country[]
{
new Country("Netherlands"),
new Country(R.drawable.bas,"Basque Country")
};
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
CountryAdapter adapter = new CountryAdapter(inflater.getContext(),R.layout.listview_item_row,countries2);
setListAdapter(adapter);
getListView().setDivider(null);
return super.onCreateView(inflater, container, savedInstanceState);
}
我的国家适配器
public class CountryAdapter extends ArrayAdapter<Country>{
Context context;
int layoutResourceId;
Country[] data = null;
public CountryAdapter(Context context, int layoutResourceId, Country[] data) {
super(context,layoutResourceId,data);
this.context = context;
this.layoutResourceId = layoutResourceId;
this.data = data;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View row = convertView;
CountryHolder holder = null;
if (row == null) {
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent,false);
holder = new CountryHolder();
holder.imgIcon = (ImageView) row.findViewById(R.id.ivCountry);
holder.txtTitle = (TextView)row.findViewById(R.id.tvCountry);
row.setTag(holder);
} else {
holder = (CountryHolder) row.getTag();
}
Country country = data[position];
holder.txtTitle.setText(country.getTitle());
holder.imgIcon.setImageResource(country.getIcon());
return row;
}
static class CountryHolder
{
ImageView imgIcon;
TextView txtTitle;
}
