小编Red*_*ne1的帖子

可能你们很多人(像我一样)都有ViewPager使用底点创建的问题,像这样:

你如何创建这样的Android ViewPager？

更新BuildTools到版本25.0.0后.

compileSdkVersion 25
buildToolsVersion "25"

我有Android布局预览的问题.现在它显示错误:

渲染期间引发异常:无法找到模式0

我试图清理和重建项目,但它不起作用.在更新之前一切都很好.

我知道我可以回到之前的版本BuildTools,但我想知道为什么它不适用于版本25.0.0？

好像这是一个问题 RecyclerView

我要创建ViewPager有Fragments,主要的问题是,每个片段的背景需要有一个削减在背景边缘.在拖动时切入应该扩大.你有什么想法怎么做吗？

看起来应该是这样的:

我正在尝试使用与Card View和Recycler View一起使用的Android教程.我想将OnClickListner附加到每张卡片上.我尝试了stackoverflow上的许多答案,但它们对我不起作用.我的部分代码.

MainActivity.java

/**
     * Adding few albums for testing

    private void prepareAlbums() {
        int[] covers = new int[]{
                R.drawable.album1,
                R.drawable.album2};

        Album a = new Album("?????", covers[0]);
        albumList.add(a);

        a = new Album("????", covers[1]);
        albumList.add(a);

        adapter.notifyDataSetChanged();
    }
