Taking a step back here. I think if I solve the Dialog itself, the
Window background drawable may not be an issue. Saying that because
once I created the 9-patch with correct transparency and Content and
Patch settings, it looks as it should.
So, trying to get the dialog layout (view) right first.
Code:
// 1 - specify the layout (pretty simple stuff)
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://
schemas.android.com/apk/res/android"
android:id="@+id/layout_root0"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#fff80000" <!-- gives me a red bar
at the top of the dialog -->
>
<ListView
android:id="@+id/shareList"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/tenth" <!-- my 9-patch.
Correctly
displays as expected -->
>
</ListView>
</LinearLayout>
// 2 - inflate and populate the View
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.bc, null);
ListView shareList =
(ListView)textEntryView.findViewById(R.id.shareList);
shareList.setAdapter(gla);
// 3. Now, display the dialog (turn off the title
bar)
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCancelable(true)
.setView(textEntryView);
mAlert = builder.create();
mAlert.requestWindowFeature(Window.FEATURE_NO_TITLE);
mAlert.show();
This code will produce a nice alert dialog with a perfect 9-patch
surrounding the ListView (options items) and a red bar at the top of
the ListView.
**Problem** -- Still have a "border" around the LinearLayout. There is
a thin black horizontal bar at the top *and* a 1-pixel frame around
the whole thing. Its that "frame" around the dialog I want to get rid
of.
Is that a remnant of the LinearLayout that wraps the ListView? Do I
need to specify some sort of "no border" attribute to the
LinearLayout? Or is it a remnant of the Dialog? Do I need to do
something beyond the requestWindowFeature (no title) statement?
