How to create dialog box inside onClick() ListView?

Question

Java

Good day.
Faced a problem: it is not possible to create a dialog box inside the ListView event handler.
Tried to copy this , but the result ended with an error

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

.
I don't understand what to do?
Here is the code:

private void setHandler(ListView listView) {
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(getApplicationContext(), map.size() + " size of database ", Toast.LENGTH_SHORT).show();
                AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
                builder.setTitle("Title");

// Set up the input
                final EditText input = new EditText(getApplicationContext());
// Specify the type of input expected; this, for example, sets the input as a password, and will mask the text
                input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                builder.setView(input);

// Set up the buttons
                builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        m_Text = input.getText().toString();
                    }
                });
                builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.cancel();
                    }
                });

                builder.show();
                displayToastInfo();
            }
        });
    }
