1.要实现这种效果
在这里插入图片描述
2.可以使用这种方式

        View v = LayoutInflater.from(mContext).inflate(R.layout.ceshi_01, null);
        PopupWindow popupWindow = new PopupWindow(v, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, true);
        popupWindow.showAsDropDown(v);
        v.findViewById(R.id.ig).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Log.d("111333", "用户点击了关闭");
                popupWindow.dismiss();
            }
        });

3.ceshi_01的布局代码如下。布局中的图片可以换成自己的图片

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="1080dp"
    android:layout_height="1920dp"
    android:background="#00000000"
    android:orientation="vertical">

    <LinearLayout
        android:id="@+id/yyy"
        android:layout_width="900dp"
        android:layout_height="1125dp"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="375dp"
        android:background="@drawable/qd_01"
        android:orientation="vertical">

    </LinearLayout>

    <ImageView
        android:id="@+id/ig"
        android:layout_width="96dp"
        android:layout_height="96dp"
        android:layout_below="@id/yyy"
        android:layout_centerHorizontal="true"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="30dp"
        android:background="@color/blue"
        app:srcCompat="@drawable/icon" />

</LinearLayout>

4.drawable/qd_01下的文件内容如下

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">


    <item android:width="900dp" android:height="1125dp">
        <shape android:shape="rectangle">
            <stroke android:width="2dp" android:color="#ff707070" />
            <solid android:color="#fff2faff" />
            <corners android:topLeftRadius="45dp" android:topRightRadius="45dp" android:bottomLeftRadius="45dp" android:bottomRightRadius="45dp" />
        </shape>
    </item>

</selector>
