i have a HorizontalScrollView, and i am adding a bunch of ListView as its children. my XML file looks something like the following. for brevity, i will omit some of the attributes.
<HorizontalScrollView>
<LinearLayout>
<ListView android:id="@+id/listView1" android:layout_width="fill_parent" android:layout_height="fill_parent"/>
</LinearLayout>
</HorizontalScrollView>
in my java code, i then populate the ListView with data. If there is only 1 or 2 records, the ListView does not extend all the way to the bottom of the screen. i see what seems to be a transparent background. how do i get rid of this behavior.
i also tried using this component from http://www.matt-reid.co.uk/blog_post.php?id=62. again, i have the same problem.
any help is appreciated.
below is the XML file. i've simply copied/pasted the control code into my package as demo.fling8.HorizontalPager.
<demo.fling8.HorizontalPager
android:id="@+id/hp"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:text= "Etiam et dui volutpat purus gravida consequat. Nullam sodales velit a nunc pretium ut tempor urna molestie. Maecenas metus enim, venenatis vel volutpat non, iaculis ut justo. Nulla venenatis malesuada quam at tincidunt. Nunc at sem eros, convallis eleifend arcu. Curabitur gravida velit nec nunc condimentum feugiat. In ultrices orci sit amet purus fermentum placerat in et lacus. Praesent sit amet sodales lectus. Morbi vehicula condimentum purus eu vulputate. Morbi risus enim, rhoncus a iaculis et, porta vitae justo."
/>
<ListView android:id="@+id/lv" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"></ListView>
</demo.fling8.HorizontalPager>
in my MainActivity.java class, this is my code to populate the ListView.
List<MyObject> dataList = DataAccessService.getDummyData();
ListView listView = (ListView)findViewById(R.id.lv);
listView.setAdapter(new MyAdapter(this, R.id.textViewTitle, dataList));
if you "fling" or "swipe", you will notice that the TextView does not suffer from this effect of having a transparent background (the whole screen is black). when you fling to the ListView, if there are only a few rows, then from where the ListView ends to the bottom of the screen, there is a transparent background.
here is a link to the project file: http://www.box.net/shared/5pybcpj8mkbfhv3j3ach. please let me know if you cannot access it. if you deploy to your device you should see the effect (of a transparent background).
here is a link to another project file: http://www.box.net/shared/i9vs6yq9j2s4ysp994et. this project file uses only a HorizontalScrollView (not the component referenced above). as you will probably observe, there is the transparent background.
