Android對話框圖片全屏

 android 自定義對話框使對話框鋪滿全屏。邊緣無縫對接，

效果圖如下：

調用方式：

 new AdFullDialog(MainActivity.this, “”, “”, “”, “”).show();

 對話框代碼：

 /**
     * 全屏廣告
     */
    public class AdFullDialog extends Dialog {
        private Context context;

        private String mUrl;

        Bitmap bmp;

        String Target_url;


        ImageView ivAdvertising;
        TextView mtv_second;
        LinearLayout layout_skip;

        public AdFullDialog(Context context, String url, String target_url, String Deep_link, List<String> deep_link_monitor_url) {
            // 更改樣式,把背景設置爲透明的
            super(context, R.style.dialog);
            this.context = context;
            mUrl = url;
