        //设置弹框窗口背景颜色透明
        this.getWindow().setBackgroundDrawableResource(R.color.transparent);
        this.getWindow().setGravity(Gravity.CENTER);
        this.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
        WindowManager.LayoutParams attributes = this.getWindow().getAttributes();
        attributes.width = WindowManager.LayoutParams.MATCH_PARENT;
        attributes.height = WindowManager.LayoutParams.MATCH_PARENT;
        this.getWindow().setAttributes(attributes);

要实现版本更新功能，弹框效果如下

update.jpg

这个时候要让弹框窗口为透明色才能实现，弹框类如下

public class UpdateDialog extends Dialog {


   public UpdateDialog(@NonNull Context context) {
       super(context);

//        mDialog = new UpdateDialog(context); //R.style.UpdateAlertDialog
       LayoutInflater inflater =
               (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
       //加载布局文件
       mLayout = inflater.inflate(R.layout.update_dialog, null, false);
       //添加布局文件到 Dialog
       this.addContentView(mLayout, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
               ViewGroup.LayoutParams.WRAP_CONTENT));

       //上边的小叉叉
       xiaochachaImg = (ImageView)mLayout.findViewById(R.id.xiaochachaId);
       //小叉叉下边的竖线
       whiteLine = (View)mLayout.findViewById(R.id.xiaochachaWhiteLineId);
       //最新版本
       zuixinbanbenTextView = (TextView)mLayout.findViewById(R.id.zuixinbanbenTextViewId);
       //新版本大小
       xinbanbendaxiaoTextView = (TextView)mLayout.findViewById(R.id.xinbanbendaxiaoId);
       //更新内容
       gengxinneirongEditext = (EditText)mLayout.findViewById(R.id.gengxinneirongId);


       //两个按钮的背景view
       btnsBackId = (LinearLayout)mLayout.findViewById(R.id.dibuanniumenId);
       //取消按钮
       cancleBtn = (RelativeLayout) mLayout.findViewById(R.id.quxiaoanniuId);
       //更新按钮和取消按钮中间的竖线
       btnCenterLine = (View)mLayout.findViewById(R.id.quxiaoCenterLineId);
       //更新按钮
       updateBtn = (RelativeLayout)mLayout.findViewById(R.id.gengxinanniuId);

       //进度条的背景view
       jindutiaoBackId = (LinearLayout)mLayout.findViewById(R.id.jindutiaoBackId);
       //进度条上面的文字
       gengxinjinduTextView = (TextView)mLayout.findViewById(R.id.gengxinjinduId);
       //进度条
       progressBar = (ProgressBar)mLayout.findViewById(R.id.jindutiaoId);


       xiaochachaImg.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               xiaochachaClickListener.onClick(v);
           }
       });

       cancleBtn.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               quxiaoClickListener.onClick(v);
           }
       });

       updateBtn.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               gengxinClickListener.onClick(v);
           }
       });

       this.setContentView(mLayout);
       this.setCancelable(true);                //用户可以点击后退键关闭 Dialog
       this.setCanceledOnTouchOutside(false);   //用户不可以点击外部来关闭 Dialog

       //设置弹框窗口背景颜色透明
       this.getWindow().setBackgroundDrawableResource(R.color.transparent);
       this.getWindow().setGravity(Gravity.CENTER);
       this.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
       WindowManager.LayoutParams attributes = this.getWindow().getAttributes();
       attributes.width = WindowManager.LayoutParams.MATCH_PARENT;
       attributes.height = WindowManager.LayoutParams.MATCH_PARENT;
       this.getWindow().setAttributes(attributes);

   }

   public UpdateDialog(@NonNull Context context, int themeResId) {
       super(context, themeResId);
   }

   protected UpdateDialog(@NonNull Context context, boolean cancelable, @Nullable OnCancelListener cancelListener) {
       super(context, cancelable, cancelListener);
   }

   private View mLayout;

   private ImageView xiaochachaImg;
