getSize() giving me errors

Question

When I implement

WindowManager wm = ((WindowManager)context.getSystemService(context.WINDOW_SERVICE));
Display display = wm.getDefaultDisplay();
m_nDisplayWi         


        

Answer 1

Try this, it works for me.

getWindowManager().getDefaultDisplay().getWidth();

Answer 2

Here is the utility method, you could utilize:

public static int getWidth(Context context) {
    WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    Display display = windowManager.getDefaultDisplay();
    Point size = new Point();
    int width;
    if (Build.VERSION.SDK_INT >= 13) {
        display.getSize(size);
        width = size.x;
    } else {
        width = display.getWidth();
    }
    return width;
}

Answer 3

This supports both older and newer devices:

private static Point getDisplaySize(final Display display) {
    final Point point = new Point();
    try {
        display.getSize(point);
    } catch (java.lang.NoSuchMethodError ignore) { // Older device
        point.x = display.getWidth();
        point.y = display.getHeight();
    }
    return point;
}

Answer 4

Sorry that I'm late to the party, but make sure you're using android sdk 13 or above.

Answer 5

This version works for API < 4, too:

@SuppressWarnings("deprecation")
@TargetApi(VERSION_CODES.HONEYCOMB_MR2)
public static Point getSize(Display display) {
    Point point = new Point();
    if (sdkInt() >= VERSION_CODES.HONEYCOMB_MR2) {
        display.getSize(point);
    } else {
        point.set(display.getWidth(), display.getHeight());
    }
    return point;
}

@SuppressWarnings("deprecation")
public static int sdkInt() {
    return Integer.parseInt(VERSION.SDK);
}

Answer 6

Try to use that instead :

Display display = getWindowManager().getDefaultDisplay();

Without that, i don't see any problem in this code ...
