 txtHeading =(TextView)findViewById(R.id.txtHeading);

I want to implement click event for textview in parent activity

Any help would be highly appreciated

Answer 1

I usually create some helper method on the parent activity

public void setHeaderOnClick(View.onClickListener clickListener){
    txtHeading =(TextView)findViewById(R.id.txtHeading);
    txtHeading.setOnClickListener(clickListener);
}

when on the fragment, you can use

((YourActivityName)getActivity()).setHeaderOnClick(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        //method here

    }
});

hope it helps

Answer 2

yes you can do it like... 1.)in your header a xml in the textView set these properties.

android:clickable="true"
android:onClick="onClick"

2.) write the direct public void onClick() in your BaseActivity Like

public void onClick(View v){
        if(v.getId() == R.id.txtHeading){

        }
    }

it will working charm yes after doing these steps don't find your text view component in BaseActivity.
