How to make responsive Android application which is used in mobile and also in tablet?

Question

I have created one Android application.

When I run my application in Mobile Phone it works very well, but when I run in Tablet the layout of application is changed.

So, how to make responsive Android application which is used in Mobile and also in Tablet?

Answer 1

On Android we can use screen size selector, introduced from Android 3.2, to define which layout to use. More details available at http://android-developers.blogspot.in/2011/07/new-tools-for-managing-screen-sizes.html. Following code snippet has been extracted from the same link :

public class MyActivity extends Activity 
{
    @Override protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate();
        Configuration config = getResources().getConfiguration();
        if (config.smallestScreenWidthDp >= 600) 
        {
            setContentView(R.layout.main_activity_tablet);
        } 
        else 
        {
            setContentView(R.layout.main_activity);
        }
    }
}

Another good reference for size configuration is keeping separator. This is explain in details at : http://www.vanteon.com/downloads/Scaling_Android_Apps_White_Paper.pdf
