Android 如何让Dialog实现背景透明

View inflate = LayoutInflater.from(context).inflate(R.layout.qrcode, null);ImageView qrcode = (ImageView) inflate.findViewById(R.id.iv_qrcode);ImageView guanbi = (ImageView) inflate.findViewById(R.id.iv_guanbi);final Dialog dialog = new AlertDialog        .Builder(context)        .setView(inflate)        .show();dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);Glide.with(context).load(list.get(position).getDwhat()).into(qrcode);Animation animation = AnimationUtils.loadAnimation(context, R.anim.scale);inflate.setAnimation(animation);animation.start();

最关键的一行代码

布局文件

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <ImageView        android:id="@+id/iv_qrcode"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:src="@mipmap/ic_launcher" />    <View        android:layout_width="match_parent"        android:layout_height="80dp"        android:background="#00000000" />    <ImageView        android:id="@+id/iv_guanbi"        android:layout_width="40dp"        android:layout_height="40dp"        android:background="@android:color/transparent"        android:layout_gravity="center"        android:src="@drawable/guanbi" />LinearLayout>
