Question

public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
    View v = null;
    if( convertView != null )
        v = convertView;
    else
        v = inflater.inflate(R.layout.child_row, parent, false); 
    Color c = (Color)getChild( groupPosition, childPosition );
    TextView color = (TextView)v.findViewById( R.id.childname );
    if( color != null )
        color.setText( c.getColor() );
    TextView rgb = (TextView)v.findViewById( R.id.rgb );
    if( rgb != null )
        rgb.setText( c.getRgb() );
    //  CheckBox cb = (CheckBox)v.findViewById( R.id.check1 );
    //  cb.setChecked( c.getState() );
    Button btnPlay=(Button)v.findViewById(R.id.Play);
    Button btnDelete=(Button)v.findViewById(R.id.Delete);
    Button btnEmail=(Button)v.findViewById(R.id.Email);
    btnPlay.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            Log.i("TEST ", "play btn cliked");

            Intent i=new Intent(this,FindFilesByType.class);//THIS IS NOT ALLOWED IN MY CODE

        }
    });

    return v;
}

In the code above, I’ve written my adapterclass.
There are 3 buttons in my explandable list as a child.
I want to call another Java class on button’s click event,
so, when I am using:

Intent i=new Intent(this,FindFilesByType.class);

I am getting this:

The constructor Intent(new View.OnClickListener(){}, Class<FindFilesByType>) is undefined
Remove arguments to match 'Intent'

What is wrong with what I am doing?

public View getChildView(int groupPosition, int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent) {
    View v = null;
    if (convertView != null)
        v = convertView;
    else
        v = inflater.inflate(R.layout.child_row, parent, false);
    Rington c = (Rington) getChild(groupPosition, childPosition);
    TextView color = (TextView) v.findViewById(R.id.childname);
    if (color != null)
        color.setText(c.getColor());
    TextView rgb = (TextView) v.findViewById(R.id.rgb);
    if (rgb != null)
        rgb.setText(c.getRgb());

    Button btnPlay = (Button) v.findViewById(R.id.Play);
    Button btnDelete = (Button) v.findViewById(R.id.Delete);
    Button btnEmail = (Button) v.findViewById(R.id.Email);
    btnPlay.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            //code

        }
    });
    btnDelete.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            //code

        }
    });
    btnEmail.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            //code
        }
    });

    return v;
}

this above methos into the adapter class this is fully working code for me 🙂
