Three kinds: Dialog, Dialog theme activities, Toast

Dialog(Alert)

Dialog d =NewDialog (myactivity. This); //use a new window to colorize the window it obscures and blur itwindow window =D.getwindow ();                Window.setflags (WindowManager.LayoutParams.FLAG_BLUR_BEHIND, WindowManager.LayoutParams.FLAG_BLUR_BEHIND); //Set TitleD.settitle ("Dialog Title"); //Expand LayoutsD.setcontentview (R.layout.dialog_view); //find the TextView used in the layout and set its text valueTextView Text =(TextView) D.findviewbyid (R.id.dialogtextview); Text.settext ("This was the text in my dialog");
D.show ();

Alertdialog.builder AD =NewAlertdialog.builder (context); Ad.settitle ("Title"); Ad.setmessage ("Message"); Ad.setpositivebutton ("Button1",NewOnclicklistener () {@Override Public voidOnClick (Dialoginterface Dialog,intwhich)        {                            }        }); Ad.setnegativebutton ("Button2",NewOnclicklistener () {@Override Public voidOnClick (Dialoginterface Dialog,intwhich)        {                            }        }); Ad.setcancelable (true); Ad.setoncancellistener (NewOncancellistener () {@Override Public voidonCancel (Dialoginterface dialog) {}}) ; Ad.show ();

Dialog Themed Events

<activity android:name= "mydialogactivity" Android:theme= "@android: Style/theme.dialog" ></activity>

Toast

Toast.maketext (This, String.Format ("name%s, gender%s, age%d", Data.getusername (), Data.getsex (), Data.getage ()), Toast.length_short). Show ();

Management of dialog boxes

The Oncreatedialog and Onpreparedialog event handlers in the activity can save and manage dialog boxes. After you create a dialog box for the first time in Oncreatedialog, each call to ShowDialog triggers Onpreparedialog, where you can modify the value you want to display

    Static Final Private intTime_dialog = 1; @OverrideprotectedDialog Oncreatedialog (intID) {Switch(ID) { Case(time_dialog): Alertdialog.builder timedialog=NewAlertdialog.builder ( This); Timedialog.settitle ("Titile"); Timedialog.setmessage ("Message"); returntimedialog.create (); }        return NULL; } @Overrideprotected voidOnpreparedialog (intID, Dialog Dialog) {        Switch(ID) { Case(time_dialog): Alertdialog timedialog=(alertdialog) dialog; Timedialog.setmessage ("New Message");  Break; }} showDialog (Time_dialog);
