Android 尽管传递了项ID，但仍获取ResourceNotFoundException

我正在构建一个应用程序，用户可以通过指定的活动创建条目，并通过长时间单击条目编辑同一活动中的条目。该应用程序使用MVVM架构，并为其数据库留出空间。当我尝试编辑条目时，会出现以下错误：

Process: com.example.cryptpass_kt, PID: 13448
    java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=2, result=-1, data=Intent { (has extras) }} to activity {com.example.cryptpass_kt/com.example.cryptpass_kt.MainActivity}: android.content.res.Resources$NotFoundException: String resource ID #0x1

错误指向我的

MainActivity.kt

文件中的

->

行：

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)

        if (requestCode == ADD_ENTRY_REQUEST && resultCode == Activity.RESULT_OK) {
            Toast.makeText(this, data?.getStringExtra(AddEditEntryActivity.EXTRA_USERNAME), Toast.LENGTH_SHORT).show()
            Toast.makeText(this, data?.getStringExtra(AddEditEntryActivity.EXTRA_PASSWORD), Toast.LENGTH_SHORT).show()
            Toast.makeText(this, data?.getStringExtra(AddEditEntryActivity.EXTRA_HINT), Toast.LENGTH_SHORT).show()

            val username = Objects.requireNonNull<Intent>(data).getStringExtra(AddEditEntryActivity.EXTRA_USERNAME)
            val password = Objects.requireNonNull<Intent>(data).getStringExtra(AddEditEntryActivity.EXTRA_PASSWORD)
            val hint = Objects.requireNonNull<Intent>(data).getStringExtra(AddEditEntryActivity.EXTRA_HINT)

            val entry = Entry(username, hint, password)
            viewModel.insert(entry)

            Toast.makeText(this, "Entry added!", Toast.LENGTH_SHORT).show()

        } else if (requestCode == EDIT_ENTRY_REQUEST && resultCode == Activity.RESULT_OK) {
            val id = Objects.requireNonNull<Intent>(data).getIntExtra(AddEditEntryActivity.EXTRA_ID, -1)

            -> Toast.makeText(this, data!!.getIntExtra(AddEditEntryActivity.EXTRA_ID, -1), Toast.LENGTH_SHORT).show()
            Toast.makeText(this, data.getStringExtra(AddEditEntryActivity.EXTRA_USERNAME), Toast.LENGTH_SHORT).show()
            Toast.makeText(this, data.getStringExtra(AddEditEntryActivity.EXTRA_PASSWORD), Toast.LENGTH_SHORT).show()
            Toast.makeText(this, data.getStringExtra(AddEditEntryActivity.EXTRA_HINT), Toast.LENGTH_SHORT).show()

            if (id == -1) {
                Toast.makeText(this, "Something went wrong", Toast.LENGTH_SHORT).show()
                return
            }

            val username = Objects.requireNonNull<Intent>(data).getStringExtra(AddEditEntryActivity.EXTRA_USERNAME)
            val password = Objects.requireNonNull<Intent>(data).getStringExtra(AddEditEntryActivity.EXTRA_PASSWORD)
            val hint = Objects.requireNonNull<Intent>(data).getStringExtra(AddEditEntryActivity.EXTRA_HINT)

            val entry = Entry(username, hint, password, id)
            entry.id = id
            viewModel.update(entry)

            Toast.makeText(this, "Entry updated", Toast.LENGTH_SHORT).show()

        } else {Toast.makeText(this, "Entry not added!", Toast.LENGTH_SHORT).show()}
    }

是完整的Github回购协议。我还可以为每个请求添加更多的代码。

Toast.makeText（）

重载接受

int

参数，它希望看到一个字符串资源id，而您正在向它传递一个不是字符串资源id的

int

：

数据！！。getIntExtra（AddedEntryActivity.EXTRA_ID，-1）

您应该使用

Toast.makeText（）

重载，该重载使用

字符串

参数-将int转换为字符串：

Toast.makeText(this, data!!.getIntExtra(AddEditEntryActivity.EXTRA_ID, -1).toString(), ...

Toast.makeText(this, data!!.getIntExtra(AddEditEntryActivity.EXTRA_ID, -1).toString(), ...
