Question

Can someone tell me if this is a bug in the SDK/IDE:

Any custom or extended layout I add to my layout XML causes the IDE to ignore the fact that there are any child views of that layout (they just disappear from the outline view/window), thus making them uneditable via the properties view/window. (I need to extend a layout to make onSetAlpha() public)

FYI: I’m developing for Android 1.5 and up, using all the latest plug-ins/updates in Eclipse

Here is a simple example of a layout XML and the extended Layout that causes this error.

[Extended Layout]

package com.test;
public class CustomLinearLayout extends LinearLayout
{

    public CustomLinearLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomLinearLayout(Context context) {
        super(context);
    }
}

[Simple layout XML]

<?xml version="1.0" encoding="utf-8"?>
<com.test.CustomLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
  <ImageView android:id="@+id/ImageView01"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"></ImageView>
</com.test.CustomLinearLayout>

ImageView01 is not visible or editable in the properties or outline views/windows.

Thanks.

When you want to edit the properties of view just replace your com.test.CustomLinearLayout
with LinearLayout.
Then you can see the view in properties and can edit the properties. After you finish editing then revert the tag to original one that is from LinearLayout to com.test.CustomLinearLayout
