Android: how to remove row from ListView with delete button in row

Question

I know that there are many threads with more or less than one topic, but none of them covers my situation:

I populate my ListView with a special CursorAdapter using my own rows. I have two states for a ListView: the first state consists only of texts in rows; the second state has a delete button in each row. Switching between two states is the button at the bottom of the view.

I am trying to achieve: in the first state, when I click on a line, the screen should switch to another view. In the second state, when I click the delete button, the selected row must be deleted from the database, the ListView must be populated, and nothing should happen if I click any other part of the row except the delete button.

I know how to delete an item and refill the ListView, and I know how to switch to another view when I click on a row in the first state; but I could not combine them. I use the following method to get id and line position:

protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); //Code goes in here either for deleting or switching into another view } 

I tried using some if statements to get a condition for clicking the delete button or for clicking on a line, but that didn't work.

The first question is obvious: how can I make it work?

The second question: in the second state, when any part of the line is pressed, except for the button of the "Delete" button, it switches to another view. How can I prevent this? I tried to set the .setClickable, .setPressed, .set Selected string attributes to false, but that didn't help.

Thanks for your answers in advance.

In the second state, when any part of the line is pressed, except for the button of the delete button, it switches to another view. How can I prevent this?

You just have a listener for deleteButton

  @Override public View getView(int position, View convertView, ViewGroup parent) { View row = null; LayoutInflater inflater = getLayoutInflater(); row = inflater.inflate(R.layout.one_result_details_row, parent, false); // inflate other items here : Button deleteButton = (Button) row.findViewById(R.id.Details_Button01); deleteButton.setTag(position); deleteButton.setOnClickListener( new Button.OnClickListener() { @Override public void onClick(View v) { Integer index = (Integer) view.getTag(); items.remove(index.intValue()); notifyDataSetChanged(); } } ); 

In getView () method you put ListItem in postion

 deleteButton.setTag(position); 

Convert getTag() to an integer

In OnClickListener() you will remove the item

  items.remove(index.intValue());

I think the code below is better for the second question:

 Button ic_delete = (Button) row.findViewById(R.id.ib_delete); ic_delete.setOnClickListener(new Button.OnClickListener() { @Override public void onClick(View v) { // delete row from database notifyDataSetChanged(); } });
