How to call startActivityForResult in class initialed from layout : main.xml

this is the same question as "how can I retrieve data from the new one to the old one".

But in my first Activity, I called setContentView(R.layout.main);. There is a surfaceview drawing on canvas.

The only method I know is to call getContext() to get the context, then call startActivity(). But I开发者_运维问答 can't call startActivityForResult() from the context I get, it seems that it doesn't support, I need to call it only in my activity class.

Can anyone give me any opinion?

EDIT:

Here is my code :

public class gameView extends SurfaceView implements SurfaceHolder.Callback
{
    public gameView(Context context, AttributeSet attrs)
    {
        //This is how I do : 
        Intent intent = new Intent();
        intent.setClass(getContext(), inputCharactorName.class);
        getContext().startActivity(intent);
        //This what I WANT to , but I don't know how
        //Activity.startActivityForResult(null,FPS);
        //I want to start the activity here;
    }
}


If you are completely sure that getContext() is an instance of an Activity then you can do:

((Activity)getContext()).startActivityForResult(intent, 0);


Can anyone give me any opinion?

Call startActivityForResult() from your activity. Have your SurfaceView or whatever call a method on your activity that triggers the call to startActivityForResult().
