Try this.

    super.onConfigurationChanged(newConfig);
    ImageView imageView = (ImageView)findViewById(R.id.imageView);
    if(getResources().getConfiguration().orientation == 2) {
        imageView.setImageDrawable(R.drawable.landscapeimage);
    } else if(getResources().getConfiguration().orientation == 1){

Answer 2

you can create Layout-land and from that you can copy paste your code from the layout folder , and change the imageview to whatever you like. now when the user change orientation it will go to the layout-land. hope that help you.

Answer 3

write this in onStart()

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();
int height = display.getHeight();

if(width<height){
   //in portrait mode

}
else{
   //in landscape mode.
}

Answer 4

you have to create new layout and put it to its designated folder such like:

- layout layout-800x400 
- layout-land 
- layout-land-800x400 
- layout-port
- layout-port-1232x800

etc.

in each folder are adjusted layout depends on what design would you want it to be like. Now, if its not working, you have to identify the dimension or resolution of your device and add it as your layout folder like sample above,coz maybe the device was unable to find the layout folder for it.
