setEmptyView上的ListView不显示在一个Android应用程序视图
问题描述:
您好有从一个ListView所述setEmptyView方法的一个问题。
Hi have a problem with the setEmptyView method from a ListView.
下面是我的Java code:
Here is my Java code:
ListView view = (ListView)findViewById(R.id.listView1);
view.setEmptyView(findViewById(R.layout.empty_list_item));
ArrayAdapter<Session> adapter1 = new ArrayAdapter<Session>(this, android.R.layout.simple_list_item_1,
android.R.id.text1, MainController.getInstanz().getItems());
view.setAdapter(adapter1);
empty_list_item:
empty_list_item:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/emptyList" >
</TextView>
列表视图:
<ListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
什么是错我的code?
当我有项目我看到他们在列表中。但是,当列表为空我没有看到的TextView
。
What is wrong with my code?
When I have items I see them in the list. But when the list is empty I don't see the TextView
.
答
问题是,我必须做一个addContentView:
the problem is, i have to do a addContentView:
View empty = getLayoutInflater().inflate(R.layout.empty_list_item, null, false);
addContentView(empty, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
view.setEmptyView(empty);
现在其优良
