关于PopWindow在底部展示时被华为虚拟键盘遮盖的问题

2017-10-18，在给领导展示自己新成果的时候又被打脸了，TMD我测试用的是小米的手机，结果领导的是华为的手机，展示底部PopWindow时最下面那一段被截掉了，废话不多说了，直接上代码：

/**
 * 获取虚拟按键的高度
 * @param context
 * @return
 */
public static Point getNavigationBarSize(Context context) {
    Point appUsableSize = getAppUsableScreenSize(context);
    Point realScreenSize = getRealScreenSize(context);
    // navigation bar on the right
    if (appUsableSize.x < realScreenSize.x) {
        return new Point(realScreenSize.x - appUsableSize.x, appUsableSize.y);
    }
    // navigation bar at the bottom
    if (appUsableSize.y < realScreenSize.y) {
        return new Point(appUsableSize.x, realScreenSize.y - appUsableSize.y);
    }
    // navigation bar is not present
    return new Point();
}

public static Point getAppUsableScreenSize(Context context) {
    WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    Display display = windowManager.getDefaultDisplay();
    Point size =new Point();
    display.getSize(size);
    return size;
}

public static Point getRealScreenSize(Context context) {
    WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    Display display = windowManager.getDefaultDisplay();
    Point size =new Point();
    if(Build.VERSION.SDK_INT>=17) {
        display.getRealSize(size);
    }else if(Build.VERSION.SDK_INT>=14) {
        try{
            size.x= (Integer) Display.class.getMethod("getRawWidth").invoke(display);
            size.y= (Integer) Display.class.getMethod("getRawHeight").invoke(display);
        }catch(IllegalAccessException e) {}catch(InvocationTargetException e) {}catch(NoSuchMethodException e) {}
    }
    return size;
}
