Android自定义布局包装内容

我正在实现自定义布局。 我将ImageView放到布局中，并在onMeasure方法中调用all children.measurew，h

一切正常，而不是包装内容行为。 视图的行为类似于匹配父视图，是全屏大小，而不是包装内容

当我想让视图成为包装内容时，请执行此操作

if (boxSize == MyBox.RATIO_MEASURE) {
                spec = MeasureSpec.AT_MOST;
                size = containerSize;

代码：

人力资源管理。。。。这看起来很棘手，因为您是从Java内部完成的

我想你想要的魔法课是LayoutParams

我不关心视图的布局参数，我想根据我的自定义lobic box类来测量它。布局参数用于确定视图的大小。实际上，视图已经在xml中设置了wrap_内容。LayoutParams用于布局。BoxLayout是布局，它不依赖于LayoutParams

@Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        for (int i = 0; i < getChildCount(); i++) {

            View v = getChildAt(i);
                    // custom layout logic
            MyBox box = getBox(v);

            int width = getMeasuredSpec(box.getWidth(), widthMeasureSpec);
            int height = getMeasuredSpec(box.getHeight(), heightMeasureSpec);

            v.measure(width, height);
        }
    }

    private int getMeasuredSpec(float boxSize, int containerSpec) {

        int containerSize = MeasureSpec.getSize(containerSpec);

        int spec;
        int size;

        if (boxSize == MyBox.RATIO_MEASURE) {
            spec = MeasureSpec.AT_MOST;
            size = containerSize;
        } else if (boxSize == 1) {
            spec = MeasureSpec.AT_MOST;
            size = containerSize;
        } else {
            spec = MeasureSpec.EXACTLY;
            size = (int) (MyBox.isScreenDependent(boxSize)
                    ? containerSize * boxSize
                    : boxSize);

        }

        return MeasureSpec.makeMeasureSpec(size, spec);
    }

    int WRAP_CONTENT= -2;
    LayoutParams params= new ViewGroup.LayoutParams(WRAP_CONTENT, WRAP_CONTENT);
    ImageView bNext_Word = (ImageView) rootView.findViewById(R.id.myimage);
mImage.setLayoutParams( params);
