遍历二维数据

方法一：

int arr[][] = { { 1 }, { 2, 3 }, { 4, 5, 6 }, { 7, 8, 9, 10 } };
        for (int x = 0; x < arr.length; x++) {
            for (int y = 0; y < arr[x].length; y++) {
                System.out.print(arr[x][y] + "、");
            }
            System.out.println("");
        }

方法二：

int arr[][] = new int[][] { { 1 }, { 1, 2 }, { 1, 2, 3 } };
  for (int i = 0; i < arr.length; i++) {
   int[] arr2 = arr[i];
   for (int c = 0; c < arr2.length; c++) {
    System.out.println(arr2[c]);
   }

方法三：

item.bind(getData(position));

public String[] getData(int position) {
    String[] a = new String[DATA[position].length];
    for (int i = 0; i < DATA[position].length; i++) {
        a[i] = DATA[position][i];
    }
    return a;
}

public void bind(String[] data) {
    mData = data;
    if (ciAdapter == null) {
        ciAdapter = new ChooseItemAdapter();
        grid.setAdapter(ciAdapter);
    } else {
        ciAdapter.notifyDataSetChanged();
    }
    text.setText(mData[0]);    　　//最后得出text
}
