Android: Allow user to edit/input text from an alert dialog

This little snippet is a simple one, but it makes the user experience a whole lot better.

Instead of implementing a new Activity/screen to enter in some text, just make it an AlertDialog() with an EditText view.

01.final EditText txtUrl = new EditText(this);

02. 

03.// Set the default text to a link of the Queen

04.txtUrl.setHint("http://www.librarising.com/astrology/celebs/images2/QR/queenelizabethii.jpg");

05. 

06.new AlertDialog.Builder(this)

07.  .setTitle("Moustachify Link")

08.  .setMessage("Paste in the link of an image to moustachify!")

09.  .setView(txtUrl)

10.  .setPositiveButton("Moustachify", new DialogInterface.OnClickListener() {

11.    public void onClick(DialogInterface dialog, int whichButton) {

12.      String url = txtUrl.getText().toString();

13.      moustachify(null, url);

14.    }

15.  })

16.  .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

17.    public void onClick(DialogInterface dialog, int whichButton) {

18.    }

19.  })

20.  .show();

This does all the magic. The example shows you how to:

• Create the edit textfield and assign some properties
• Build the dialog
• Set the title/message for the dialog
• Embed the text field
• Do something after the user clicks OK or Cancel

Obviously you're gonna have to fill the positive button action with your own intentions.

Have fun!
