Question

I am new to Android, Eclipse and partly Java (decade ago I read a Java book and never used it.) I am following this tutorial: http://ofps.oreilly.com/titles/9781449390501/Android_User_Interface.html

I have this code:

public class Status extends Activity implements OnClickListener, TextWatcher {
  // ...
  class PostToTwitter extends AsyncTask<String, Integer, String> {
    // ...
    protected void onPostExecute(String result) { 
      Toast.makeText(Status.this, result, Toast.LENGTH_LONG).show();
    }
  }
}

I get these errors next to the Toast.makeText line:

• The method makeText(Context, CharSequence, int) in the type Toast is not applicable for the arguments (AsyncTask.Status, String, int)
• No enclosing instance of the type AsyncTask.Status is accessible in scope

1. I am not sure why I get an error?
2. Why is it mentioning AsyncTask when I am passing the Status activity context?

I guess I am going to slap myself and say Doh! later, but I have starred myself blind at it now 🙂

Answer 1

You problem is that Status is a public enum of AsyncTask. So java takes not your activity as a context. Try to hold a instance of your context in your AsyncTask.

Try this code here:

public class Status extends Activity implements OnClickListener, TextWatcher {
  private Context context;
  public void onCreate(...) {
    context=this;
    //...
  }

  // ...
  class PostToTwitter extends AsyncTask<String, Integer, String> {
    // ...
    protected void onPostExecute(String result) { 
        Toast.makeText(context, result, Toast.LENGTH_LONG).show();
    }
  }
}
