Android Customization dialog box

Android Customization dialog box

Sometimes Android built-in dialog box does not meet our needs, perhaps the function is not complete or not in line with our interface design requirements, this time we need to get a set of our own dialog box, below I will tell you a very simple way to create their own dialog box.

Create a style first: <style name= "You name Yourself" parent= "@android: Theme.dialog" >.......</style> This I believe everyone knows.

Then create your own dialog box layout: What you want to design yourself

Create your own dialog class to inherit the dialog, namely:

Public Mydialog extends dialog{

This class contains this construction method.

Public Mydialog (context context, int theme) {
Super (context, theme);
This.context = context;

}

And then create this method, which is actually similar to the activity

protected void OnCreate (Bundle savedinstancestate) {
Super.oncreate (savedinstancestate);
This.setcontentview (r.layout. Dialog layout you created);

}

}

It is important to note that if you have a dialog box with the event you want to handle, such as the best implementation Onclicklistener interface for exiting a dialog or clicking a button

And then you use your own dialog in the activity.

Dialog Dialog = new Mydialog (Applicationcaractivity.this,
R.style.mydialog); Note R.style.mydialog This is the style you created.

Below I put the code of the process I have done below:

The style created first:

<name= "Mydialog"  parent= "@android: Theme.dialog">          <item name= "Android:windowframe" > @null </item>        <item name= "Android:windownotitle ">true</item>         <item name=" Android:windowbackground "> @drawable/ic_launcher</item>        <item name= "android:windowisfloating" >true</item>        <item name= "Android: Windowcontentoverlay "> @null </item>           </style>

I'm not going to explain what's inside.

And then there's my dialog layout: layout whatever it is, everybody just look at it.

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"Android:background= "#ffffff"android:orientation= "vertical" >        <LinearLayoutAndroid:layout_width= "Fill_parent"Android:layout_height= "Wrap_content"android:orientation= "Horizontal">        <DatePickerAndroid:id= "@+id/date_picker1"Android:calendarviewshown= "false"Android:layout_width= "Wrap_content"Android:layout_height= "150DP"style= "@style/apptheme"/>    <TimepickerAndroid:id= "@+id/time_picker1"Android:layout_width= "Wrap_content"Android:layout_height= "150DP"/>    </LinearLayout>    <LinearLayoutAndroid:layout_width= "Fill_parent"Android:layout_height= "Wrap_content"android:orientation= "Horizontal"android:gravity= "Center">        <ButtonAndroid:id= "@+id/butn_sure"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:text= "OK"/>      <ButtonAndroid:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:background= "#ffffff"Android:text="          "/>        <ButtonAndroid:id= "@+id/butn_no"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:text= "Cancel"/>    </LinearLayout></LinearLayout>

This is a custom dialog.

Class Mydialog extends Dialog implements Android.view.View.OnClickListener {private context context;        Private Button butn;        Private Timepicker Timepicker;        Private DatePicker DatePicker;        Public Mydialog (Context context) {//super (context);            //TODO auto-generated constructor stub//} public Mydialog (context context, int theme) {            Super (context, theme);            This.context = context;  TODO auto-generated constructor stub} protected void OnCreate (Bundle savedinstancestate) {//        TODO auto-generated Method Stub super.oncreate (savedinstancestate); SetTheme (Android.            R.style.theme_devicedefault_light_noactionbar_fullscreen);            This.setcontentview (r.layout.dialog_test);            DatePicker = (datePicker) Findviewbyid (r.id.date_picker1);            Timepicker = (timepicker) Findviewbyid (r.id.time_picker1); Resizepikcer (DatePicker);            Butn = (Button) Findviewbyid (r.id.butn_sure);            EDT = (EditText) Findviewbyid (R.id.number);        Butn.setonclicklistener (this);  } @Override public void OnClick (View arg0) {//TODO auto-generated method stub switch (Arg0.getid ())                {Case R.id.butn_sure://String str = Edt.gettext (). toString ();                Edt1.settext (str);                StringBuffer sb = new StringBuffer ();                        Sb.append (String.Format ("%d-%02d-%02d%02d:%02d", Datepicker.getyear (), Datepicker.getmonth () + 1,                        Datepicker.getdayofmonth (), Timepicker.getcurrenthour (),                Timepicker.getcurrentminute ()));                if (i = = 1) {edt5.settext (SB);                } else if (i = = 2) {edt6.settext (SB);                } This.dismiss (); Break; }        }    }    

Finally, in the use of activity, I write in a method:

private void Mydialog () {        Dialog Dialog = new Mydialog (applicationcaractivity.this,                r.style.mydialog);        window window = Dialog.getwindow ();//Builder.getwindow ();        Window.setgravity (Gravity.bottom); Here you can set the location of the dialog display        window.setwindowanimations (r.style.mystyle);        Dialog.settitle ("Please set the time");        Dialog.show ();                Dialog.getwindow (). setlayout (620, 414);                 /         * * Set the size of the dialog box as a percentage of the screen size         *        /WindowManager m = Getwindowmanager ();        Display d = m.getdefaultdisplay (); Get screen width, high with        windowmanager.layoutparams p = window.getattributes ();//Get dialog box current parameter value        p.height = (int) ( D.getheight () *0.4); The height is set to the screen of 0.6        p.width = (int) (D.getwidth ());//width is set to the 0.65        Window.setattributes (p) of the screen;                                    }

We refer to each other to learn, small caught dead. Thank you for coming to our humble abode!
