Question

I’m using the afreechart library to display some charts in my app. The problem is the class extends DemoView class, and getIntent() is from Activity class. I have to pass some extras in the chart app to make chart treatement. What can i do? Any proposals please?
Thank you very much.

Answer 1

Inside your View you can cast getContext() to the Activity which contains your View and thus you can access anything from that Activity.

class MyActivity {
...

private MyView mMyView;

public void onCreate(Bundle savedState) {
     mMyView = (MyView)findViewById(R.id.myid);
}

public int getImportantInt() { return 0; }

}

class MyView extends View {

....

private doSomethingWithImportantInt() {

    MyActivity parent = (MyActivity)getContext(); // I meant this line

    int myImportantInt = parent.getImportantInt();

....

}
}
