Delete a LinearLayout on long press event

I am creating a LinearLayout dynamically. I need to delete the LinearLayout on LongPress event.

My code : 

public void addTileView(View v) {         
      _parentLayout = (LinearLayout) findViewById(R.id.gridCont); 

    View child = getLayoutInflater().inflate(R.layout.customtileview,null);
     ((TextView)child.findViewById(R.id.tileText)).setText("Tile View :"+_tileViewCount++);       
    _parentLayout.addView(child);       
    _parentLayout.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            Toast.makeText(getApplicationContext(), "Delete", Toast.LENGTH_SHORT).show();

            return true;
        }
    });

}

How to do this ?

This works for me.

public void addTileView(View v) {

      _parentLayout = (LinearLayout) findViewById(R.id.gridCont);

      child = getLayoutInflater().inflate(R.layout.customtileview,null);
     ((TextView)child.findViewById(R.id.tileText)).setText("Tile View :"+_tileViewCount++);



    _parentLayout.addView(child);

    child.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            Toast.makeText(getApplicationContext(), "Delete", Toast.LENGTH_SHORT).show();
            _parentLayout.removeView(v);
            return true;
        }
    });



}

Thanks

Its better to remove the view which you added in the parent . Say Parent layout is the main layout and child layout is the one which you want to remove. You should try parent_layout.removeView(child_layout);

removeAllViews() - will remove all the views inside the view , but not the main view .

Please refer to ViewGroup ViewGroup vg = (ViewGroup)(myView.getParent()); vg.removeView(myView);

Alternatively , You can make the visibility of your view to Visible.GONE , and then make it visible when required.

try this,

_parentLayout.setOnLongClickListener(new OnLongClickListener() { 
    @Override
    public boolean onLongClick(View v) {
        // TODO Auto-generated method stub
        Toast.makeText(getApplicationContext(), "Delete", Toast.LENGTH_SHORT).show();

           parentLayout.removeAllViews();
        return true;
    }
});
