my listview doesn't fill parent
提问by Tsunaze
<RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" <TextView android:id="@+id/tv_test" android:text="Test " android:layout_width="wrap_content" android:layout_height="wrap_content" /> <ListView android:id="@+id/list_test" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_below="@id/tv_test" ></ListView> </RelativeLayout>
<RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" <TextView android:id="@+id/tv_test" android:text="Test " android:layout_width="wrap_content" android:layout_height="wrap_content" /> <ListView android:id="@+id/list_test" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_below="@id/tv_test" ></ListView> </RelativeLayout>
And everything is in a ScrollView, i don't know why but the relative layout seems to set a wrap content. And it makes the ListView small and not taking the whole place.
一切都在 ScrollView 中，我不知道为什么，但相对布局似乎设置了换行内容。它使 ListView 变小而不是占据整个地方。
I don't know if it's useful but here's my java code :
我不知道它是否有用，但这是我的 Java 代码：
public class ShowView extends Activity{
ListView lv;
ArrayAdapter<String> adapter;
String[] myList = {"One", "Two", "Three", "Four", "Five", "Six", "Seven", "Height", "Nine", "Ten"};
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.show);
lv = (ListView) findViewById(R.id.list_test);
adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1, myList);
adapter.setDropDownViewResource(android.R.layout.simple_list_item_1);
lv.setAdapter(adapter);
}
}

I think you ScrollView is not filling the entire screen. Use this inside scrollView
我认为您 ScrollView 没有填满整个屏幕。在滚动视图中使用它
android:fillViewport="true"

Replace the RelativeLayoutwith a vertical LinearLayout, and set android:layout_weight="1"and android:layout_height="wrap_content"on your ListView:
将 替换RelativeLayout为垂直LinearLayout，android:layout_weight="1"并android:layout_height="wrap_content"在您的 ListView 上设置和：
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="@+id/tv_test"
android:text="Test "
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="@+id/list_test"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_below="@id/tv_test" />
</LinearLayout>

Also, I would remove the ScrollViewaltogether. ListViewmanages scrolling itself, and you will run in to all kinds of problems if you embed it inside a container which handles scrolling. If you want to scroll @is/tv_testalong with your ListViewcontent, then consider putting it inside your ListViewas a header. If you want it to remain static when the ListViewscrolls, then keep it outside the ListView.
另外，我会ScrollView完全删除。ListView管理滚动本身，如果您将其嵌入处理滚动的容器中，您将遇到各种问题。如果你想@is/tv_test随着你的ListView内容滚动，那么考虑把它放在你ListView的标题中。如果您希望它在ListView滚动时保持静态，请将其放在ListView.
