android - 获取资源编号 0x00000000 错误的值时没有包标识符

Question

我创建了一个 fragment ，用户可以在其中编辑他们的信息，但是每当我在 android studio 中运行该应用程序时，它总是给我这个错误:在获取资源编号 0x00000000 的值时没有包标识符。我也无法从抽屉导航中打开此网页。

Answer 1

        editText2.setText((int) infoDataSource.getFirst().getIncome());
        editText3.setText((int) infoDataSource.getFirst().getGoal());

您不小心使用了 setText(int resId) 的重载版本而不是 setText(String text) 并且在这种情况下找不到标识符为 0 的字符串资源.
