最近在看自定義View的一些源碼,發(fā)現(xiàn)有的項(xiàng)目中在onMeasure()中使用resolveSize(),這個方法是什么意思啊?為什么要這樣用?    @Override    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        super.onMeasure(widthMeasureSpec, heightMeasureSpec);        // 為何要調(diào)用resolveSize()方法?        int width = resolveSize(DEFAULT_VIEW_SIZE, widthMeasureSpec);        int height = resolveSize(DEFAULT_VIEW_SIZE, heightMeasureSpec);        mViewSize = Math.min(width, height);        setMeasuredDimension(width, height);    }
