Method 1
public static boolean isTablet(Context context) {
return (context.getResources().getConfiguration().screenLayout
& Configuration.SCREENLAYOUT_SIZE_MASK)
>= Configuration.SCREENLAYOUT_SIZE_LARGE;
}
Method 2
Determine whether it is a phone or a tablet by calculating the size of the device:
/**
* Determine whether it is a flat plate
*
* @return
*/
private boolean isPad() {
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
// The width of the screen
float screenWidth = display.getWidth();
// The screen height
float screenHeight = display.getHeight();
DisplayMetrics dm = new DisplayMetrics();
display.getMetrics(dm);
double x = Math.pow(dm.widthPixels / dm.xdpi, 2);
double y = Math.pow(dm.heightPixels / dm.ydpi, 2);
// The screen size
double screenInches = Math.sqrt(x + y);
// Is greater than 6 Size is Pad
if (screenInches >= 6.0) {
return true;
}
return false;
}
