下面这段代码有问题。它应该做的是获取 arrDBNumbers 中的数字并使用这些数字用 6 个不同的图像填充列表视图。arrDBNumbers 已满，并通过 int a - f 他们被填满，但在
hm.put("flag1", Integer.toString(balls[a]) );
一切都挂了？？？它不会超过这个，我得到一个 Array Index Out Of Bounds 异常

下面的代码可以工作，并将 6 个图像放在一个列表视图中。但他们所有相同的图像 1 - 6 重复。
List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();
for(int i = 0; i < 50; i++){
HashMap<String, String> hm = new HashMap<String,String>();
hm.put("flag1", Integer.toString(balls[1]) );
hm.put("flag2", Integer.toString(balls[2]) );
hm.put("flag3", Integer.toString(balls[3]) );
hm.put("flag4", Integer.toString(balls[4]) );
hm.put("flag5", Integer.toString(balls[5]) );
hm.put("flag6", Integer.toString(balls[6]) );
aList.add(hm);
}
String[] from = { "flag1","flag2","flag3","flag4","flag5","flag6" };
int[] to = { R.id.ivB1,R.id.ivB2,R.id.ivB3,R.id.ivB4,R.id.ivB5,R.id.ivB6};
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.results_row, from, to);
ListView listView = ( ListView ) findViewById(R.id.listView1);
listView.setAdapter(adapter);
有人知道出了什么问题吗？我试过了
hm.put("flag1", String.valueOf(balls[a]) );
hm.put("flag1", balls[a].toString() );
