我不知道如何解决这个问题，请帮助。我唯一能说的是，如果我注释掉setListAdapter(cursorAdapter);，代码会运行，但我的ListView. 可能有用的代码的任何其他部分让我知道。谢谢您的帮助。

我加载了 android 2.1 源代码并且能够找到它失败的地方，但我仍然不明白它。
它在 bindView 内的 SimpleCursorAdapter 类中失败。下面是 bindView，它在 String text = cursor.getString(from[i]);中失败了
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");
}
}
}
}
}
