无法从 int? 转换为 int 运行时出现错误
This error occurs when you are trying to call the method `makeText()` on an anonymous `Runnable` object, but the method signature does not match any of the available `makeText()` methods.
The `makeText()` method is used to display a toast message in an Android application. It takes three arguments:
1. A `Context` object
2. A string message to be displayed
3. An integer value representing the duration of the message display
To resolve this error, you need to ensure that you are calling the `makeText()` method with the correct arguments. Check that the first argument is a `Context` object and that the second argument is a string. Also, ensure that the third argument is one of the available duration constants defined in the `Toast` class.
For example, to display a short toast message in an activity, you can use the following code:
```
Toast.makeText(this, "Hello World!", Toast.LENGTH_SHORT).show();
```
Here, `this` refers to the current activity context, "Hello World!" is the message to be displayed, and `Toast.LENGTH_SHORT` is the duration constant.
