Listview onitemclickevent crashes my app

Question

I am very new to Android development (though not to development in general). I am trying to create an app which:

Opens SMS inbox when a user taps a button and display them in listview (done)

Uri inboxURI = Uri.parse("content://sms/inbox");

// List required columns
String[] reqCols = new String[] { "_id", "address", "body" };

// Get Content Resolver object, which will deal with Content Provider
ContentResolver cr = getContentResolver();

// Fetch Inbox SMS Message from Built-in Content Provider
Cursor c = cr.query(inboxURI, reqCols, null, null, null);

// Attached Cursor with adapter and display in listview
adapter = new SimpleCursorAdapter(this, R.layout.row, c,
    new String[] { "body", "address" }, new int[] {
    R.id.lblMsg, R.id.lblNumber });
lvMsg.setAdapter(adapter);

When the user taps one message from the list, I want to get the body of the txt message (failed to do)

I am using this code in activity_main but it causes my app to close once I tap an item from the list

lvMsg.setOnItemClickListener(new OnItemClickListener() {
  @Override
  public void onItemClick(AdapterView<?> parent, View view, int position,
    long id) {

    String item = ((TextView)view).getText().toString();

    Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show();
  }
});

Logcat

        String item = ((TextView)view).getText().toString();

to

    TextView textView = (TextView) view.findViewById(R.id.lblMsg);

String item= textview.getText().toString();

oops: you have CursorAdapter. inside onItemClick.

  c.moveToPosition(position);

         String body = c.getString(c.getColumnIndexOrThrow("body"));

or

Cursor cursor = (Cursor) parent.getItemAtPosition(position);
String body = cursor.getString(cursor.getColumnIndexOrThrow("body"));

or try this How to get the item id in an onItemClick handler
