How to define AlertDialog.Builder inside a newView/bindView

Question

I have a ListView and I'm using SimpleCursorAdapter to populate the content, and newView & bindView to get the View.

I want to enable that everytime the button on the row list is clicked, it loads an AlertDialog box.

Here's the code:

btn.setOnClickListener(new OnClickListener() {
 public void onClick(View view) {
    Intent intent = getIntent();
    if (intent != null) {
    Uri uri = intent.getData();
    if (uri != null) {
    Cursor cursor = managedQuery(uri, new String[] {
    BaseColumns._ID, Database.Project.C_PRICE, Database.Project.C_KEYWORD,
    Database.Project.C_SHORTCODE}, null, null, null);

if (cursor == null) {
finish();
} else {
if (cursor.moveToFirst()) {

AlertDialog.Builder alertbox = new AlertDialog.Builder(this);                                             
alertbox.setTitle("SMS");

I always get an error on this line: AlertDialog.Builder alertbox = new AlertDialog.Builder(this);

It says: The constructor AlertDialog.Builder(new View.OnClickListener(){}) is undefined

how am I able to do that?

Answer 1

You are using this to create the AlertDialog.Builder which is wrong use Activity_name.this. You are applying the button's listener's reference to create the AlertDialog.Builder rather you should have the reference of the Activity.

AlertDialog.Builder alertbox = new AlertDialog.Builder(Activity_name.this);

Answer 2

try this way

btn.setOnClickListener(new OnClickListener() {
     public void onClick(View view) {
         AlertDialog.Builder alertbox = new AlertDialog.Builder(view.getContext());
     }
}
