Question

I fetch record from database using following code.

 for (LocWiseProfileBeans cn : LocWiseProfile) {
        // get a reference for the TableLayout
        TableLayout table = (TableLayout) findViewById(R.id.locprofile_table);

        // create a new TableRow
        TableRow row = new TableRow(this);

        // count the counter up by one
        counter++;


        String log = "Loc Name: "+cn.getLocname()+" ,Lattitude: " + cn.getLattitude()+ " ,Longitude: " + cn.getLongitude()+ " , Selected Profile :"+cn.getSelectedprofile();
        TextView t = new TextView(this);
        // set the text to "text xx"
        t.setText(cn.getLocname());

        TextView t2 = new TextView(this);
        t2.setText(cn.getSelectedprofile());
        row.addView(t);
        row.addView(t2);
        table.addView(row,new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

But i need to enable this record for deletion on user request.
Means if user click on second record then this record will be delete.
I try to find the answer but not find any appropriate answer…….
Please provide me reference code or article.
Thank you in Advance!

Answer 1

You can do this by setting onClickListener to your row.
To determine which row is clicked, you can set a unique tag to that row.

row.setTag(counter);  //  use counter or index for tag, so you can get the data from LocWiseProfile later
row.setOnClickListener(new OnClickListener()  {
    @Override
    public void onClick(View v)  {
        int tag = (Integer)view.getTag();
        LocWiseProfileBeans cn = LocWiseProfile.get(tag);
        //  Perform delete action here
        //  ...
    }   
});

If you want to simply display the result from db as a list, I suggest you using ListActivity or ListView, with using adapter you can show and manage your data in more simple way.
