How to start a new Activity from a CustomView?

Question

Usually you would start an activity with something like the following:

private void llMenuSettings_Click() {
     this.runOnUiThread(new Runnable() {
          public void run() {
               Intent intent = new Intent(XXXXXXXX.this, View_Settings.class);
               startActivity(intent);
               XXXXXXXX.this.finish();
          }
     });
}

However I am extending a LinearLayout:

public class MenuContainer extends LinearLayout {
}

Therefore I have run into a couple of issues:

1. How would you know what XXXXXXXX is in the example as the LinearLayout can be included in multiple Layouts?
2. startActivity() does not exist in a LinearLayout class?

There are a few similar questions but none that fully answer the above scenario therefore hoping this can be answered and help others in the future?

Answer 1

Inside your LinearLayout extending class, you could create the following method:

public void launch() {

    Intent i = new Intent(getContext(), YourActivity.class);
    getContext().startActivity(i);
}

Use the getContext() method inside your customview to retrieve the Context and start a new Activity.
