使用相同的代码获取未找到资源的异常资源ID 0x0

问题描述

调用一个依次调用AlertDialog的方法时出现此错误

E/AndroidRuntime: FATAL EXCEPTION: main

这是一个谜，因为我在同一应用程序的其他活动中使用相同的代码没有问题。同样神秘的是它可以在某些设备，仿真器上运行，即它可以在API 23设备和仿真器以及API 28仿真器上运行，但是在API 27上却给我一个错误。

public void selectFile() {
    if (!databaseAccess.permission(this))
        return;
    File mPath = new File(Environment.getExternalStorageDirectory() +  "//Documents//" );
    FileDialog fileDialog = new FileDialog(this,mPath,"txt");
    // only supports one file extension

    fileDialog.addFileListener(new FileDialog.FileSelectedListener() {
        public void fileSelected(File file) {
            String full = file.getAbsolutePath();
            importfile.setText(full);
        }
    });
    fileDialog.showDialog();
}

我调用的fileDialog方法是我从中获得的 https://stackoverflow.com/a/13986063/4106573

，显然是在尝试使用显示对话框时发生的

    dialog = builder.show();
    return dialog;

我以前已经看到过，这与无效上下文有关，因此我怀疑它无法识别活动。

我认为可能是因为
“实现PopupMenu.OnMenuItemClickListener”，但对其进行修改不会改变任何内容。

以下是主题和辅助样式。

解决方法

我找到了补救办法。 在FileDialog类中，我更改了CreateFileDialog方法以在创建构建器时指定常规主题。

代替

    AlertDialog.Builder builder = new AlertDialog.Builder(activity);

我用

    AlertDialog.Builder builder = new AlertDialog.Builder(activity,R.style.LightTheme);

“黑暗主题”显然存在问题，但是我还是希望它变亮，所以我很好。

在应用程序的其他地方，我注意到我曾经使用过

    final AlertDialog.Builder builder = new AlertDialog.Builder(context,R.style.darkAlertDialog);

指定深色版本。希望对别人有帮助。
