  1. POAndroid ListActivity Scrollview How to get a list to scroll
    text
    copied!<p>I was going through a tutorial on <a href="http://www.vogella.de/articles/AndroidListView/article.html" rel="nofollow">http://www.vogella.de/articles/AndroidListView/article.html</a> 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. </p> <p>The code is below:</p> <pre><code>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&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(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(); } } </code></pre> <p>//The xml file: </p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" &gt; &lt;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" &gt; &lt;/ImageView&gt; &lt;TextView android:id="@+id/label" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@+id/label" android:textSize="20px" &gt; &lt;/TextView&gt; &lt;/LinearLayout&gt; </code></pre> <p>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.</p> <p>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? </p> <p>I'd appreciate any input. Thanks</p>
