Accessing Parent-View at many levels above

Question

I have a linearlayout, which contains my TextView I want access. In this linearlayout there is a listview, where every item is a linearlayout and contains also custom views.

Deep in there is a button with an onclickListener. After performing onClick(), I want to call a method which sets the text of my textview. At the moment I am doing it like this:

(View)this.getParent().getParent().getParent().getParent().getParent().getParent().getParent().findViewById(R......)

It works, but it looks bad. Is there any possibility to do it a better way?

Yes, its ugly, don't do that.

In your onClick(View v) get hold of TextView by asking Activity holding the layout:

@Override
public void onClick(View v) {
    TextView tv = (TextView) YourActivity.this
        .findViewById(R.id.your_text_view_id);
    tv.setText("blabla");
}

if you do it from fragment instead of activity use :

YourFragment.this.getView().findViewById(R.id.your_text_view_id) 

Or simply create a member TextView mTv, initialize it in your #OnCreate and use it everywhere as suggested in comments to your question
