Description softlion 2013-02-23 13:01:20 UTC
With the following code which sets the background of an ImageButton view to a drawable, the designer never display the correct UI. It completely ignores the background. It works perfectly in the simulator and on the device though.

                android:layout_alignParentBottom="true" />

with a drawable shape in bottomTab_inactiveBtn.xml in the Drawable resource folder:

<?xml version="1.0" encoding="utf-8"?>
<!-- http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

        <solid android:color="#CCCCCC" />
        <corners android:radius="1dp" android:topLeftRadius="10dp" android:topRightRadius="10dp" android:bottomLeftRadius="0dp" android:bottomRightRadius="0dp"  />
        <padding android:left="6dp" android:top="6dp" android:right="6dp" android:bottom="6dp" />

Had same issue with an ImageView widgets. It doesn't display pictures in the designer window, but it works ok on the emulator and the real device.

Comment 3 Lluis Sanchez 2014-05-08 13:05:50 UTC
The problem seems to be caused by the "<?xml version="1.0" encoding="utf-8"?>" directive. If you remove that line, the background is properly renderer. This is a problem in the Android SDK. We'll try to find a workaround.

Test case

Updating with a zipped-up test case and some more verbose details since I wrote them up before I found this report.

## Steps to reproduce

1. Open the attached test case in Xamarin Studio.

2. Double-click "Resources/layout/Main.axml" in the solution pad to open the layout in the Android designer.

`Main.axml` includes an attribute `android:background="@drawable/shape_one"` to set the background to the `shape_one.xml` drawable resource.

## Results

The designer renders the Main layout with a black background rather than the cyan background from the "shape_one" resource.

### Error from `Ide.log` file

I think the corresponding error in `~/Library/Logs/XamarinStudio-5.0/Ide.log` is this:

## Expected results / "workarounds"

- The same combination of `shape_one.xml` and `Main.axml` is rendered correctly by the Android designer in Eclipse.

- Running the test case on device or emulator produces the correct result: the background is cyan rather than black. (as mentioned in comment 1)

- Removing the `<?xml version="1.0" encoding="utf-8"?>` line from `shape_one.xml` stops the problem. (as mentioned in comment 3)

Closing as using Android Studio designer with XamarIdea is much much faster and works fine
