Android Custom Dialog Simple instance

In Android applications, the most missing is the custom dialog, for the system provided by default dialog style, generally do not compound the style we apply.
Custom dialog requires 3 steps:
1, the main rewrite dialog Java class
2, clear dialog Theme, in the Style.xml file add one can
3. How to use

First, create the Custompopdialog2.java class

 PackageCom.lenovocw.music.app.widget;ImportCOM.LENOVOCW.ZHUHAIZXT.R;ImportAndroid.app.Dialog;ImportAndroid.content.Context;ImportAndroid.graphics.Bitmap;ImportAndroid.view.LayoutInflater;ImportAndroid.view.View;ImportAndroid.view.WindowManager.LayoutParams;ImportAndroid.widget.ImageView;/** * This custom dialog app in: Share pop-up box to view QR code * * @author shanhy ([email protected]) * @date December 4, 2015 */ Public  class CustomPopDialog2 extends Dialog {     Public CustomPopDialog2(Context context) {Super(context); } Public CustomPopDialog2(Context context,intTheme) {Super(context, theme); } Public Static  class Builder {        PrivateContext context;PrivateBitmap image; Public Builder(Context context) { This. Context = Context; } PublicBitmapGetImage() {returnImage } Public void setimage(Bitmap image) { This. image = Image; } PublicCustomPopDialog2Create() {Layoutinflater inflater = (layoutinflater) context. Getsystemservice (Context.layout_inf Later_service);FinalCUSTOMPOPDIALOG2 dialog =NewCUSTOMPOPDIALOG2 (Context,r.style.dialog); View layout = Inflater.inflate (R.layout.dialog_share_qrcode,NULL); Dialog.addcontentview (Layout,NewLayoutparams (Android.view.ViewGroup.LayoutParams.WRAP_CONTENT, Android.view.ViewGr Oup.            Layoutparams.wrap_content));            Dialog.setcontentview (layout);            ImageView img = (ImageView) Layout.findviewbyid (R.id.img_qrcode); Img.setimagebitmap (GetImage ());returnDialog }    }}

Here's a simple explanation, our custom dialog needs to prepare a view layout file, focusing on the Create () method, which in this case shows a picture directly.

Second, add theme in Style.xml, we call R.style.dialog in the Create method

<stylename="Dialog"Parent="Android:style/theme.dialog"> <Item name="Android:background">#00000000 </item><Item name="Android:windowbackground"> @android: color/transparent</Item> <Item name="Android:windownotitle">true</Item> <Item name="Android:windowisfloating">true</Item> </style>

Iii. using a custom dialog

        Bitmap bitmap = xxxxx;// 这里是获取图片Bitmap，也可以传入其他参数到Dialog中        CustomPopDialog2.Builder dialogBuild = new CustomPopDialog2.Builder(context);        dialogBuild.setImage(bitmap);        CustomPopDialog2 dialog = dialogBuild.create();        dialog.setCanceledOnTouchOutside(true);// 点击外部区域关闭        dialog.show();
