向 RecyclerView 添加多个 ArrayList

Question

我试图在 recyclerview 中以列表格式列出文本和图像，并在每一行中显示我的代码，我知道它的错误原因它只显示一行我必须如何编辑代码。还在学习java

ArrayList<DataList> dataList = new ArrayList<DataList>();

    for (int i = 0; i < 1; i ++ ) {

        dataList.add(new DataList(

                "France",
                "Russia",
                R.drawable.lt1,
                "America",
                "Europe",
                R.drawable.lt2
        ));
    }

    ArrayList<DataList2> dataList2 = new ArrayList<DataList2>();

    for (int i = 0; i < 1; i ++ ) {

        dataList2.add(new DataList2(

                "South Africa",
                "Brazil",
                R.drawable.lt1,
                "New Zeland",
                "Pakistan",
                R.drawable.lt2
        ));
    }

Answer 1

您只是在迭代循环 1 time 。

for (int i = 0; i < 1; i ++ ) {
                    /\
                    ||
                 Iterate it more times
}

喜欢

for (int i = 0; i < n; i ++ ) {// n times or as much as you want 

}

Answer 2

您应该将它们添加到 RecyclerView 将显示的项目的一个主要 ArrayList 中。
