警报对话框中的密码字段

Question

我创建了一个带有编辑文本的警报对话框。如何设置edittext的属性为密码？

这里是代码...

final AlertDialog.Builder alert = new AlertDialog.Builder(this);
final EditText input = new EditText(this);

input.setInputType(InputType.TYPE_CLASS_TEXT| InputType.TYPE_TEXT_VARIATION_PASSWORD);

alert.setView(input);    //edit text added to alert
alert.setTitle("Password Required");   //title setted

Answer 1

input.setTransformationMethod(PasswordTransformationMethod.getInstance());
