Android的ListActivity滚动型如何获得一个列表中滚动 [英] Android ListActivity Scrollview How to get a list to scroll
问题描述
我正在经历一个教程 http://www.vogella.de/articles /AndroidListView/article.html
学习如何做使用ListActivity。我试图让在列表中滚动,但来到意识到,你不能使用滚动视图在布局文件来做到这一点。围绕谷歌搜索后,我意识到,android的不允许,但我一直没能找到,这似乎解释了如何使滚动发生一个答案。
I was going through a tutorial on http://www.vogella.de/articles/AndroidListView/article.html learning how to do use ListActivity. I am trying to get the list to scroll, but came to realize that you can't use scrollview in the layout file to make this happen. After googling around, I realized that android doesn't allow this, but I haven't been able to find an answer that seems to explain how to make the scrolling happen.
在code是如下:
public class MyListActivityActivity extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
"Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
"Linux", "OS/2", "iPhone", "WindowsMobile",
"Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
"Linux", "OS/2" , "iPhone", "WindowsMobile",
"Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
"Linux", "OS/2" };
/*LayoutInflater factory = getLayoutInflater();
LinearLayout footer =
(LinearLayout) factory.inflate(R.layout.main, null);
getListView().addFooterView(footer); */
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.rowlayout, R.id.label, values);
setListAdapter(adapter);
}
protected void onListItemClick(ListView l, View v, int position, long id) {
String item = (String) getListAdapter().getItem(position);
Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
}
}
//的XML文件:
//The xml file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:id="@+id/icon"
android:layout_width="22px"
android:layout_height="22px"
android:layout_marginLeft="4px"
android:layout_marginRight="10px"
android:layout_marginTop="4px"
android:src="@drawable/ic_launcher" >
</ImageView>
<TextView
android:id="@+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/label"
android:textSize="20px" >
</TextView>
</LinearLayout>
目前,您放入数组的多个值,较小的列表成为以确保它适合在屏幕上。我希望文本保持相同的大小,让它成为一个长长的清单,我可以滚动查看。
Currently, the more values you put into the array, the smaller the list becomes to make sure that it fits on the screen. I want the text to stay the same size and let it be a long list that I could scroll through.
我在什么地方的addHeader左右和addFooter那将会使滚动发生读取。但是,任何人都可以向我解释或使我有关于如何实现这一信息的来源?
I've read somewhere about addHeader and addFooter that'd enable the scrolling to happen. But can anyone explain to me or lead me to a source that has more information about how to implement this?
我倒是AP preciate任何输入。谢谢
I'd appreciate any input. Thanks
推荐答案
的的ListView
本身就是一个滚动窗口小部件,所以它不能的内部使用滚动型
the ListView
is itself a scrolling widget, so it can't be used inside of a ScrollView
