这段代码是一个自定义View的onMeasure方法，用于测量View的大小。它首先调用measureHeight和measureWidth方法分别计算高度和宽度，然后设置View的测量尺寸为计算出的高度和宽度。
重构后的代码如下：
```java
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int measuredHeight = measureHeight(heightMeasureSpec);
int measuredWidth = measureWidth(widthMeasureSpec);
setMeasuredDimension(measuredHeight, measuredWidth);
}
private int measureHeight(int measureSpec) {
int specMode = MeasureSpec.getMode(measureSpec);
int specSize = MeasureSpec.getSize(measureSpec);
int result = 500;
if (specMode == MeasureSpec.AT_MOST) {
result = specSize;
} else if (specMode == MeasureSpec.EXACTLY) {
result = specSize;
}
return result;
}
private int measureWidth(int measureSpec) {
int specMode = MeasureSpec.getMode(measureSpec);
int specSize = MeasureSpec.getSize(measureSpec);
int result = 500;
if (specMode == MeasureSpec.AT_MOST) {
result = specSize;
} else if (specMode == MeasureSpec.EXACTLY) {
result = specSize;
}
return result;
}
```
