Android: Adding multiple Views to a Linear Layout dynamically

Question

I checked the solution here:

Its given that, create a new View everytime you add it instead of changing only 1 view.

But i am doing this:

for (int i = 0; i < 10; i++) {

LayoutInflater vi = (LayoutInflater) getApplicationContext().getSystemService(
                    CommentsActivity.LAYOUT_INFLATER_SERVICE);
View cv = vi.inflate(R.layout.item, null);

TextView textView1 = (TextView) cv.findViewById(R.id.tv1);
textView1.setText("-" + i);
TextView textView2 = (TextView) cv.findViewById(R.id.tv2);
textView2.setText("--" + i);
LinearLayout insertPoint = (LinearLayout) findViewById(R.id.layout);
insertPoint.addView(cv, 0, new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
}

so its like creating a new inflater and view for every i. But i am only getting the last item.

ie.., only 1 inflatedView with tv1 as -9 and tv2 as --9

seems like everytime i go into the for loop, the old view is being replaced by the new view. How to add all the 10 views??

ThankYou

Your have to set layout parameter and add rule to it...:)

usually I use this

private void renewDetail(){
        llDetail.removeAllViews();
        for (int i = 0; i < 10; i++) {
            llDetail.addView(new ChildDetailNotePieDiagram(context, "Name", 1000, 10));
        }
    }

the logic is first I clear all view from the parent layout and then add view to the parent layout.

where llDetail is a linear layout and I create a linear layout class ChildDetailNotePieDiagram and add it to the linear layout so basically it's a different solution from what you use now but I think you can try my solution if you want :) feel free to ask any question about this in the comment

So can I use this in the for loop before adding view: ((ViewGroup)cv.getParent()).removeView(cv);??
