下面的代码有问题。 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listview。 arrDBNumbers已满，并且经过int a -f它们被填充，但是在
hm.put("flag1", Integer.toString(balls[a]) );
public class ResLotto extends Activity {
int[][] arrDBNumbers = new int[100][8];
String[] arrDBNumbersS = new String[60];
String st0, st1, st2, st3, st4, st5, st6, st7, st8, st9, st10, st11, st12, st13, st14, st15, st16, st17, st18, st19, st20, st21, st22, st23, st24, st25, st26, st27, st28, st29;

int[] balls = new int[]{R.drawable.b1, R.drawable.b2, R.drawable.b3, R.drawable.b4, R.drawable.b5, R.drawable.b6, R.drawable.b7, R.drawable.b8, R.drawable.b9,

SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.results_row, from, to);
ListView listView = ( ListView ) findViewById(R.id.listView1);
listView.setAdapter(adapter);
}
下面的代码可以工作，并在列表视图中放入6个图像。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);
有谁知道出了什么问题？ 我试过了
hm.put("flag1", String.valueOf(balls[a]) );
hm.put("flag1", balls[a].toString() );
