Hi, I've got a custom class being loaded up by my layout XML, and drawing to the screen. This much works perfectly.
First some background: In my main layout XML I define a tabhost, linearlayout, framelayout and tabwidget. Following on from this, each activity has its own layout XML that defines how its UI is laid out inside the parent framelayout when the activities are launched by selecting a tab. The problem comes when I try to draw a line at the bottom of the canvas in the overridden onDraw(Canvas) function in my custom view (class CompassView extends View); it is drawn underneath the tabwidget defined in the main parent XML! I fetch the size of the canvas with canvas.getHeight(). The value it returns seems to include the space underneath the tabwidget, but not the space occupied by the notification bar at the top. Note that my tabwidget is at the bottom of the screen. Here is the layout for the child view which sits inside the framelayout of the parent XML: -------------------------------- <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:id="@+id/compass" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.tjhowse.geoloc.CompassView android:layout_width="fill_parent" android:layout_height="fill_parent"/> </LinearLayout> -------------------------------- At the start of the constructor for my custom view: -------------------------------- public CompassView(Context context, AttributeSet attrs) { super(context, attrs); setLayoutParams(new LayoutParams(context, attrs)); ... -------------------------------- I would've thought the fill_parent attribute would've prevented the view, and thus the canvas, from overlapping with the tabwidget. If I replace my custom class with: -------------------------------- <Button android:id="@+id/pbTest" android:layout_width="wrap_content" android:layout_height="fill_parent" android:text="BUTAN OMG" /> -------------------------------- ...the button correctly fills the available space, and has a proper bottom edge that clearly finishes before it intersects the tabwidget. Any thoughts? Thanks, tjhowse. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
