[android-developers] Re: VideoView inside a ListView

[rayworks]

Hi, there

Please note that VideoView is a kind of SurfaceView. As the doc mentions 
SurfaceView:

*The surface is Z ordered so that it is behind the window holding its

One of the solutions for having Video content in a scrolling view container 
could be using TextureView 
 to 
wrapper  MediaPlayer the same as VideoView does.

Hope it could help.

 Is there any way to make a Webview have a transparent background?

 Thanks.

RTM pls.

public void setBackgroundColor (int color)
Set the background color. It's white by default. Pass zero to make the
view transparent.

[android-developers] Re: Place a custom view on a relative layout programmatically

[rayworks]

         MyCustomView customView = new MyCustomView(this);
         // Settings here the margin : Doesn't works!
         MarginLayoutParams mLayoutParams = new MarginLayoutParams(338,
 338);
         mLayoutParams.setMargins(100, 100, 0, 0);
         customView.setLayoutParams(mLayoutParams);
         mainLayout.addView(customView, 0, mLayoutParams);

Replace with the following codes and you will find the custom view on
the right position:

// for testing only
MyCustomView customView = new MyCustomView(this);
RelativeLayout.LayoutParams layoutParam = new
RelativeLayout.LayoutParams(100, 100);
layoutParam.setMargins(100, 100, 0, 0);
mainLayout.addView(customView, 0, layoutParam);

BTW, for specified width and height of this custom view, you need to
check the View.onMeasure()  method.
