AlertDialog

public class AlertDialog
extends Dialog implements DialogInterface

java.lang.Object
↳	android.app.Dialog
	↳	android.app.AlertDialog

Known direct subclasses

DatePickerDialog, ProgressDialog, TimePickerDialog

DatePickerDialog	A simple dialog containing an `DatePicker`.
ProgressDialog	This class is deprecated. `ProgressDialog` is a modal dialog, which prevents the user from interacting with the app. Instead of using this class, you should use a progress indicator like `ProgressBar`, which can be embedded in your app's UI. Alternatively, you can use a notification to inform the user of the task's progress.
TimePickerDialog	A dialog that prompts the user for the time of day using a `TimePicker`.

A subclass of Dialog that can display one, two or three buttons. If you only want to display a String in this dialog box, use the setMessage() method. If you want to display a more complex view, look up the FrameLayout called "custom" and add your view to it:

 FrameLayout fl = findViewById(android.R.id.custom);
 fl.addView(myView, new LayoutParams(MATCH_PARENT, WRAP_CONTENT));

The AlertDialog class takes care of automatically setting WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM for you based on whether any views in the dialog return true from View.onCheckIsTextEditor(). Generally you want this set for a Dialog without text editors, so that it will be placed on top of the current input method UI. You can modify this behavior by forcing the flag to your desired mode after calling onCreate(Bundle).

Protected constructors

AlertDialog

protected AlertDialog (Context context)

Creates an alert dialog that uses the default alert dialog theme.

The default alert dialog theme is defined by R.attr.alertDialogTheme within the parent context's theme.

Parameters
`context`	`Context`: the parent context

See also:

R.styleable.Theme_alertDialogTheme

AlertDialog

protected AlertDialog (Context context, 
                boolean cancelable, 
                DialogInterface.OnCancelListener cancelListener)

Creates an alert dialog that uses the default alert dialog theme and a custom cancel listener.

This is functionally identical to:

     AlertDialog dialog = new AlertDialog(context);
     alertDialog.setCancelable(cancelable);
     alertDialog.setOnCancelListener(cancelListener);

The default alert dialog theme is defined by R.attr.alertDialogTheme within the parent context's theme.

Parameters
`context`	`Context`: the parent context
`cancelable`	`boolean`
`cancelListener`	`DialogInterface.OnCancelListener`

See also:

R.styleable.Theme_alertDialogTheme

AlertDialog

protected AlertDialog (Context context, 
                int themeResId)

Creates an alert dialog that uses an explicit theme resource.

The specified theme resource (themeResId) is applied on top of the parent context's theme. It may be specified as a style resource containing a fully-populated theme, such as R.style.Theme_Material_Dialog, to replace all attributes in the parent context's theme including primary and accent colors.

To preserve attributes such as primary and accent colors, the themeResId may instead be specified as an overlay theme such as R.style.ThemeOverlay_Material_Dialog. This will override only the window attributes necessary to style the alert window as a dialog.

Alternatively, the themeResId may be specified as 0 to use the parent context's resolved value for R.attr.alertDialogTheme.

Parameters
`context`	`Context`: the parent context
`themeResId`	`int`: the resource ID of the theme against which to inflate this dialog, or `0` to use the parent `context`'s default alert dialog theme

See also:

R.styleable.Theme_alertDialogTheme
