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.
final EditText txtUrl = new EditText(this);
// Set the default text to a link of the Queen
txtUrl.setHint("http://www.librarising.com/astrology/celebs/images2/QR/queenelizabethii.jpg");
new AlertDialog.Builder(this)
.setTitle("Moustachify Link")
.setMessage("Paste in the link of an image to moustachify!")
.setView(txtUrl)
.setPositiveButton("Moustachify", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String url = txtUrl.getText().toString();
moustachify(null, url);
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
})
.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!
