任何人都可以帮我解决这个问题吗？它非常沮丧，因为我看不出哪里会出错。该应用程序的重点是将心电图信号获取到应用程序，绘制并存储它 ***编辑:添加appEntryAdapter

public static class AppEntryAdapter extends BaseAdapter {
        private LayoutInflater mInflater;
        private Context mContext;
        private ArrayList<AppEntry> mAppEntries;

        public AppEntryAdapter(Context context, ArrayList<AppEntry> entries) {
            mContext = context;
            mAppEntries = entries;
            mInflater = LayoutInflater.from(context);
}

这是 mainActivity 中的第 137 行和第 138 行

final AppEntry entry = mAppEntries.get(arg0);
appButton.setText(mContext.getString(entry.displayNameResID()));

我找到了解决方案。因为有 2 个 STRING.XML 文件(出于某种我不知道的原因)，它们被 IDE 混淆了。当我删除 1 时，它就起作用了非常感谢大家帮助我:)

从日志中可以清楚地看出问题:您正在尝试检索不可用的字符串资源。最有可能的是，您使用了拼写错误的 ID。首先查看 MainActivity.java:138 并查看您想要获取的字符串 ID。

还要检查布局 XML - 可能您已经为正在加载的 View 定义了一些文本，但该文本的字符串在您的资源中不存在。
