11 | 12 | 因为经常用到Relative,所以先重写 RelativeLayout 13 | 14 | 后来因为Material Design的水波效果又加上了FrameLayout 15 | 16 | 使用方法： 17 | ```xml 18 | 25 | ``` 26 | 首先呢，你需要，自己确定高或者宽的具体尺寸 27 | 然后呢app:by 这个填入之前确定尺寸的是高还是宽 28 | app:h 29 | app:h 30 | 这两个呢，就是宽高比了，直接填入IOS的尺寸也是可以的呀:) 31 | 32 | 要有别的？ 33 | 构造方法填入 34 | ```java 35 | TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.RatioLayout, defStyleAttr, 0); 36 | //获取参考边 37 | reference = typedArray.getInt(R.styleable.RatioLayout_by, 0) == 0 ?

42 | typedArray.recycle(); 43 | ``` 44 | 外面填入 45 | ```java 46 | //获取基准边的尺寸 47 | int childSpec = reference == ReferenceType.WIDTH ? getMeasuredWidth() : getMeasuredHeight(); 48 | 49 | 50 | // 如果以宽为基准边则宽不变，高按比例得出具体数值，反之亦然 51 | setMeasuredDimension( 52 | (int) (reference == ReferenceType.WIDTH ? childSpec : childSpec * ratioWidth / ratioHeight), 53 | (int) (reference == ReferenceType.HEIGHT ? childSpec : childSpec * ratioHeight / ratioWidth) 54 | );
