copied!<p>I was also trying out this script, as I'm new to Android programming and I was looking for some good examples to learn from.</p> <p>My app force closes when I add the layout to the main.xml.</p> <p>When I add the layout for the ExpendablePanel, the graphical layout becomes grayed out and I can't edit it:</p> <pre><code><?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:cl="http://schemas.android.com/apk/lib/com.martin.myapp.widgets" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <com.martin.myapp.widgets.ExpandablePanel android:orientation="vertical" android:layout_height="wrap_content" android:layout_width="fill_parent" cl:handle="@+id/expand" cl:content="@+id/value" cl:collapsedHeight="50dip"> <TextView android:id="@id/value" android:layout_width="fill_parent" android:layout_height="wrap_content" android:maxHeight="50dip" /> <Button android:id="@id/expand" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="More" /> </com.martin.myapp.widgets.ExpandablePanel> </code></pre> <p>So this is essentially an empty app without the custom widget.</p> <p>I made a ExpandablePanel.java and copied the script that extends LinearLayout in there, gives me no errors. My attrs.xml is also error free.</p> <p>Eclipse gives me no errors when running. It runs and sends it to my phone fine. That's where it force closes. When I remove the ExpandablePanel layout in main.xml it runs and is an empty app.</p> <p>I really can't figure it out.</p>
