getNavBarHeight(Context context) bug

[lanyan520]

I found on the HUAWEI phone test, NavBar transparent, get to the NavaBarHeight=0(android 5.1), which is not right, it should be used to obtain the following program NavBarHeight:

`
public int getNavBarHeight(Context context) {
int navigationBarHeight = 0;
Resources rs = context.getResources();
int id = rs.getIdentifier("navigation_bar_height", "dimen", "android");
if (id > 0 && checkDeviceHasNavigationBar(context)) {
navigationBarHeight = rs.getDimensionPixelSize(id);
}

    return navigationBarHeight;
}

private boolean checkDeviceHasNavigationBar(Context context) {
    boolean hasNavigationBar = false;
    Resources rs = context.getResources();
    int id = rs.getIdentifier("config_showNavigationBar", "bool", "android");
    if (id > 0) {
        hasNavigationBar = rs.getBoolean(id);
    }
    try {
        Class systemPropertiesClass = Class.forName("android.os.SystemProperties");
        Method m = systemPropertiesClass.getMethod("get", String.class);
        String navBarOverride = (String) m.invoke(systemPropertiesClass, "qemu.hw.mainkeys");
        if ("1".equals(navBarOverride)) {
            hasNavigationBar = false;
        } else if ("0".equals(navBarOverride)) {
            hasNavigationBar = true;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return hasNavigationBar;

}`
