当ListView的Adapter没有数据时,我们可以让它显示一个“暂无数据”的View,这个View可以是TextView或者其他...
例如:
具体代码:
xml代码:
<ListView android:id="@+id/lv_faq" android:layout_width="match_parent" android:layout_height="match_parent" /> <TextView android:id="@+id/tv_listview_empty" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="center_horizontal" android:drawableLeft="@drawable/listitem_empty" android:drawableStart="@drawable/listitem_empty" android:gravity="center" android:text="@string/listitem_empty" android:textColor="@color/listitem_little_gray" android:textSize="@dimen/text_size_15" android:textStyle="bold" />
java代码:
mFAQListView = (ListView)mFaqView.findViewById(R.id.lv_faq); TextView emptyView = (TextView)mFaqView.findViewById(R.id.tv_listview_empty); mFaqList = getData(); mAdapter = new ListViewFaqAdapter(getActivity(), mFaqList); mFAQListView.setAdapter(mAdapter); mFAQListView.setEmptyView(emptyView);
