How To Start A New Activity When Screen Orientation Changes? Android

I am writing an application which in portrait view has a gallery at the top and when you click a picture it will inflate and fill the entire screen. This works however in landscape

Solution 1:

The right way to do it is to define two layouts, one in layout-port and one in layou-land directories. That is, you will have the following two layouts: res/layout-port/main.xml and res/layout-land/main.xml.

In your software you simply write secContentView(R.layout.main); and android will take care of applying the right layout upon device rotation.

Solution 2:

Make an extra layout xml file for landscape mode and put it into the folder "layout-land"

Solution 3:

Add this to your Activity:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    startActivity(newActivity)
}

Note that this is a bad idea. Actually, it's a really bad idea. A much better alternative would be to either force one orientation or to create a layout that looks great on both orientations.
