Set View Width Programmatically

Question

I am trying to set the width and height of a view in code to show an ad for a free app I am working on  All of the UI is done in XML with the exception of this ad  Here is the code that displays the ad  It is in onCreate   AdView adView   new AdView this  ad url   my ad key  true true   LinearLayout layout    LinearLayout  findViewById R id testing   adView setAdListener this   layout addView adView     This results in the ad being displayed like this  As you can see the width doesn t quite fill the whole page     Now when I change the code to this to attempt to set the size   AdView adView   new AdView this  ad url   my ad key  true true   LinearLayout layout    LinearLayout  findViewById R id testing   adView setLayoutParams new LinearLayout LayoutParams LayoutParams WRAP CONTENT                          LayoutParams WRAP CONTENT    adView setAdListener this   layout addView adView     I get this     I have tried all different combinations of FILL PARENT and WRAP CONTENT all with the same result  Is there something I am missing  Or another way I can have the ad fill the width of the device without filling the height  Any suggestions and help is greatly appreciated   EDIT when I try to put it in XML I get an exception    lt LinearLayout xmlns android  http   schemas android com apk res android  android layout width  fill parent  android layout height

yourView setLayoutParams new LinearLayout LayoutParams width  height

This code let you fill the banner to the maximum width and keep the ratio  This will only work in portrait  You must recreate the ad when you rotate the device  In landscape you should just leave the ad as is because it will be quite big an blurred   Display display   getWindowManager   getDefaultDisplay    int width   display getWidth    double ratio     float   width   300 0  int height    int  ratio 50    AdView adView   new AdView this  ad url   my ad key  true true   LinearLayout layout    LinearLayout  findViewById R id testing   mAdView setLayoutParams new FrameLayout LayoutParams LayoutParams FILL PARENT height    adView setAdListener this   layout addView adView

The first parameter to LayoutParams is the width and the second is the height  So if you want the width to be FILL PARENT  but the width to be  say  20px  then use something new LayoutParams FILL PARENT  20   Of course you should never use actual pixels in your code  you ll need to conver that to density-independent pixels  but you get the idea  Also  you need to make sure your parent LinearLayout has the right width and height that you re looking for  Seems to be you want the LinearLayout to fill the parent width-wise and then have the adview fill that linearlayout witdh-wise as well  so you probably need to specify android layout width  fill parent  and android layout height  wrap content  in your linear layout s xml
