Android自定義Dialog(美化界面)

前言:在做項目的時候,發現dialog界面太醜陋,從csdn上下載下傳了一份自定義dialog的源碼,在他的基礎上對界面進行美化...有需要的朋友可以直接拿走

效果圖如下：

主要代碼:

/**

public class customdialog extends dialog {  

    public customdialog(context context) {  

        super(context);

        super(context, theme);  

    public static class builder {  

        private context context;  

        private string title;  

        private string message;  

        private string positivebuttontext;  

        private string negativebuttontext;

        public builder setnegativebutton(string negativebuttontext,  

            this.negativebuttontext = negativebuttontext;  

        //建立dialog對象   主要就是這個方法,加載自定義布局檔案  

        public customdialog create() {  

            layoutinflater inflater = (layoutinflater) context  

                    .getsystemservice(context.layout_inflater_service);  

            // instantiate the dialog with the custom theme  

            final customdialog dialog = new customdialog(context,  

                    r.style.dialog);  

            view layout = inflater.inflate(r.layout.dialog_normal_layout, null);  

            dialog.addcontentview(layout, new layoutparams(  

                    layoutparams.fill_parent, layoutparams.wrap_content));  

            // set the dialog title  

            ((textview) layout.findviewbyid(r.id.title)).settext(title);  

            // set the confirm button  

            if (positivebuttontext != null) {  

                ((button) layout.findviewbyid(r.id.positivebutton))  

                        .settext(positivebuttontext);  

                if (positivebuttonclicklistener != null) {  

                    ((button) layout.findviewbyid(r.id.positivebutton))  

                            .setonclicklistener(new view.onclicklistener() {  

                                public void onclick(view v) {  

                                    positivebuttonclicklistener.onclick(dialog,  

                                            dialoginterface.button_positive);  

                                }  

                            });  

                }  

            } else {  

                // if no confirm button just set the visibility to gone  

                layout.findviewbyid(r.id.positivebutton).setvisibility(  

                        view.gone);  

            }  

            // set the cancel button  

            if (negativebuttontext != null) {  

                ((button) layout.findviewbyid(r.id.negativebutton))  

                        .settext(negativebuttontext);  

                if (negativebuttonclicklistener != null) {  

                    ((button) layout.findviewbyid(r.id.negativebutton))  

                                    negativebuttonclicklistener.onclick(dialog,  

                                            dialoginterface.button_negative);  

                layout.findviewbyid(r.id.negativebutton).setvisibility(  

            // set the content message  

            if (message != null) {  

                ((textview) layout.findviewbyid(r.id.message)).settext(message);  

            } else if (contentview != null) {  

                ((linearlayout) layout.findviewbyid(r.id.content))  

                        .removeallviews();  

                ((linearlayout) layout.findviewbyid(r.id.content)).addview(  

                        contentview, new layoutparams(layoutparams.fill_parent,  

                                layoutparams.fill_parent));  

            dialog.setcontentview(layout);  

            return dialog;  

}  

4.activity中如何調用:

customdialog.builder builder = new customdialog.builder(this);  

builder.setmessage("這個就是自定義的提示框");  

builder.settitle("提示");  

builder.setpositivebutton("确定", new dialoginterface.onclicklistener() {  

    public void onclick(dialoginterface dialog, int which) {  

        dialog.dismiss();  

        //設定你的操作事項  

});  

builder.setnegativebutton("取消",  

        new android.content.dialoginterface.onclicklistener() {  

            public void onclick(dialoginterface dialog, int which) {  

                dialog.dismiss();  

        });  

builder.create().show();
