Return a global shared Resources object that provides access to only system resources (no application resources), and is not configured for the current screen (can not use dimension units, does not change based on orientation, etc).

Usage

From source file:Main.java

public static float getScreenLargestWidth() {
    DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics();

    int widthPixels = metrics.widthPixels;
    int heightPixels = metrics.heightPixels;

    float scaleFactor = metrics.density;

    float widthDp = widthPixels / scaleFactor;
    float heightDp = heightPixels / scaleFactor;

    return Math.max(widthDp, heightDp);
}

From source file:Main.java

/**
 * Convert DP to pixels using the device screen density
 *//*from   w w  w .  ja v a2  s. c  o  m*/
public static int dpToPx(int dp) {
    float density = Resources.getSystem().getDisplayMetrics().density;
    return Math.round(dp * density);
}

From source file:Main.java

public static float getScreenSmallestWidth() {
    DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics();

    int widthPixels = metrics.widthPixels;
    int heightPixels = metrics.heightPixels;

    float scaleFactor = metrics.density;

    float widthDp = widthPixels / scaleFactor;
    float heightDp = heightPixels / scaleFactor;

    return Math.min(widthDp, heightDp);
}

From source file:Main.java

    DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics();
    return new Point(metrics.widthPixels, metrics.heightPixels);
}

From source file:Main.java
