1.适配注意事项收集（笔记）

1.Android View未显示时获取其高度（https://blog.csdn.net/u010886975/article/details/53007490）

public int[] unDisplayViewSize(View view) {
        int size[] = new int[2];
        int width = View.MeasureSpec.makeMeasureSpec(0,
                View.MeasureSpec.UNSPECIFIED);
        int height = View.MeasureSpec.makeMeasureSpec(0,
                View.MeasureSpec.UNSPECIFIED);
        view.measure(width, height);
        size[0] = view.getMeasuredWidth();
        size[1] = view.getMeasuredHeight();
        return size;
    }

 public boolean isNavigationBarShow(){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            Display display = getActivity().getWindowManager().getDefaultDisplay();
            Point size = new Point();
            Point realSize = new Point();
            display.getSize(size);
            display.getRealSize(realSize);
            boolean  result  = realSize.y!=size.y;
            return realSize.y!=size.y;
        }else {
            boolean menu = ViewConfiguration.get(getActivity()).hasPermanentMenuKey();
            boolean back = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK);
            if(menu || back) {
                return false;
            }else {
                return true;
            }
        }
    }
