我不知道如何解决这个问题，请帮忙。我唯一能说的是，如果我发表评论setListAdapter(cursorAdapter);，代码就会运行，但ListView上没有任何内容。代码中可能有用的任何其他部分让我知道。谢谢你的帮助。

我加载了android 2.1源码，并且能够找到它失败的地方，但我仍然不理解它。
在bindView内的SimpleCursorAdapter类中失败。下面是bindView，它在 String text = cursor.getString（from [i]）;
中失败public void bindView(View view, Context context, Cursor cursor) {
final View[] holder = mHolders.get(view);
final ViewBinder binder = mViewBinder;
final int count = mTo.length;
final int[] from = mFrom;
for (int i = 0; i < count; i++) {
final View v = holder[i];
if (v != null) {
boolean bound = false;
if (binder != null) {
bound = binder.setViewValue(v, cursor, from[i]);
}
if (!bound) {
**String text = cursor.getString(from[i]);**
if (text == null) {
text = "";
}
if (v instanceof TextView) {
setViewText((TextView) v, text);
} else if (v instanceof ImageView) {
setViewImage((ImageView) v, text);
} else {
throw new IllegalStateException(v.getClass().getName() + " is not a " +
" view that can be bounds by this SimpleCursorAdapter");
}
}
}
}
}
答案 0 :(得分：0)
在我看来，您使用变量i来计算mTo数组的长度。你确定mTo的大小不大于[]或holder []的大小吗？因为如果你想在i上访问所有这些数组，你最好确保它们都具有相同数量的元素，否则你只是在寻找麻烦。
