Creating a custom OnClickListener

Question

I have an ArrayList of Buttons where my OCL needs to know which index I has been pressed. The plan is something like this:

MyOnClickListener onClickListener = new MyOnClickListener() {

        @Override
        public void onClick(View v) {
            
            Intent returnIntent = new Intent();
            returnIntent.putExtra("deleteAtIndex",idx);
            setResult(RESULT_OK, returnIntent);
            finish();

        }
    };
    for (int i =0;i<buttonList.size();i++) {
        buttonList.get(i).setText("Remove");
        buttonList.get(i).setOnClickListener(onClickListener);
    }

How does my implementation of the OCL need to look like ?

Currently I have this:

    public class MyOnClickListener implements OnClickListener{
    
    int index;
    
    public MyOnClickListener(int index)
    {
        this.index = index;
    }

    @Override
    public void onClick(View arg0) {
        
        
    }
}

However, I am unsure of what I need to do within the constructor of my OCL, aswell as the overriden onClick function.

Answer 1

set setOnClickListener to Button as :

buttonList.get(i).setOnClickListener(new MyOnClickListener(i));

EDIT :

I need to finish an activity in myOCL, how would I do that?

for finishing Activity on Button Click from non Activity class you will need to pass Activity Context to your custom OnClickListener as :

buttonList.get(i).setOnClickListener(new MyOnClickListener(i, Your_Current_Activity.this));

and change the Constructor of your custom OnClickListener class to :

int index;
Context context; 
public MyOnClickListener(int index,Context context)
{
    this.index = index;
    this.context=context;
}

@Override
public void onClick(View arg0) {

    // now finish Activity as\
    context.finish();
      //  OR
        // ((Activity)context).finish();
}
