[android-developers] XML Layout SERIOUSLY misbehaving
I'm trying to build the layout for my camera app. The camera preview goes on the left, and is set to the largest supported size that fits within 65% of the display width and 100% of the display height. The remaining 35% of the width is for two things: first, a TableLayout (set inside of a ScrollView) with textviews and spinners (side by side) for spinner labels and the spinners themselves. Below that is a LinearLayout (horizontal) for a TextView and the shutter release image. The left side works fine. No problem. The right side works fine on my tablet, but not on my phone (Motorold Bravo MB520). What inevitably happens with the layout on my phone is the textviews/spinners taking the full screen, and the shutter release button is nowhere to be seen. I've played around with the weights, and nothing seems to change the end result. I've tried setting the width and height of the image from Java...nothing. I've tried resizing the image and changing its density...no change. I've tried setting the width and height of the two layouts on the left (when both were LinearLayouts ... before the TableLayout), and every time I've tried to do this, I get a force close with the logcat data shown below, saying that android.widget.LinearLayout$LayoutParams cannot be cast to android.widget.FrameLayout$LayoutParams. Just one problem: NOWHERE in any my project will you find the word Frame (ignoring case for the fgrep).

Re: [android-developers] XML Layout SERIOUSLY misbehaving
By reading this: android.widget.LinearLayout$LayoutParams cannot be cast to android.widget.FrameLayout$LayoutParams I'd say you need to change this: msettingsLayout.setLayoutParams(new LinearLayout.LayoutParams(settingsw, settingsh)); into: msettingsLayout.setLayoutParams(new *FrameLayout*.LayoutParams(settingsw, settingsh)); This is most probably because your LinearLayout msettingsLayout is inside a FrameLayout, and so its layout params must be of its parent class.

LinearLayout is not a FrameLayout. I just remembered that ScrollView *is* a FrameLayout, my bad. The layout params of the ScrollView's child should be ScrollView.LayoutParams (or FrameLayout.LayoutParams.) A child must always use the layout params type declared in its parent.

Actually.you need to use LinearLayout.LayoutParams to set the layout parameters. scaleType, alpha are the ImageView parameters. Basically, anything that start with layout_ is a layout parameter.

Re: [android-developers] XML Layout SERIOUSLY misbehaving
If your ImageView has a LinearLayout parent then you would write: myImageView.setLayoutParams(new LinearLayout.LayoutParams()); If your ImageView has a FrameLayout parent, then you would write: myImageView.setLayoutParams(new FrameLayout.LayoutParams()); And so on. This is why the LayoutInflater.inflate() method takes a parent as an argument. The parent parameter is used to infer the type of LayoutParams. That might be your bug if you are not building your UI from Java code.
