在视图寻呼机中更改当前视图的宽度和高度

Question

int width = params.width + 20;             int height = params.height + 240;             view.setLayoutParams（new ViewGroup.LayoutParams（width，height））;我基本上想在视图分页器中展开当前视图。

这是我尝试的但是这不会改变当前视图上的任何内容。

 private ViewPager.OnPageChangeListener mPageListener = new  ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {
        View view = mViewPager.findViewWithTag(position);
        if (view == null)
            return;
        view.measure(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        ViewGroup.LayoutParams params = view.getLayoutParams();
        int width = params.width + 20;
        int height = params.height + 240;
        view.setLayoutParams(new ViewGroup.LayoutParams(width, height));
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
};

使用：

view.setLayoutParams(new LayoutParams(width, height));
