Try the below xml

custom_dialog_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:id="@+id/rl_dialog_container"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:padding="16dp">

<View
    android:id="@+id/imagePadding"
    android:layout_width="match_parent"
    android:layout_height="70dp" />

<LinearLayout
    android:id="@+id/round_dialog_container"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/imagePadding"
    android:background="#ffffff"
    android:gravity="bottom"
    android:orientation="vertical">

    <View
        android:id="@+id/imagePadding2"
        android:layout_width="match_parent"
        android:layout_height="70dp" />

</LinearLayout>

<ImageView
    android:id="@+id/dialog_image"
    android:layout_width="140dp"
    android:layout_height="140dp"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:src="@mipmap/ic_launcher" />

</RelativeLayout>

And when you are displaying your dialog, follow the code below:

     Dialog dialog = new Dialog(MainActivity.this);
            dialog.setContentView(R.layout.custom_dialog_layout);
            //The line below is important
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
            dialog.show();

This will definitely help you try this.

<RelativeLayout
    android:layout_width="300dp"
    android:layout_height="300dp"
    android:layout_centerInParent="true">
    <View
        android:layout_width="match_parent"
        android:id="@+id/li1"
        android:background="@android:color/transparent"
        android:layout_height="50dp"
        android:orientation="horizontal">
    </View>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_below="@+id/li1"
        android:background="#ff0000"
        android:layout_height="match_parent">

    </LinearLayout>
    <ImageView
        android:layout_width="100dp"
        android:layout_centerHorizontal="true"
        android:background="#ffd500"
        android:layout_height="100dp" />

</RelativeLayout>

use this code inside Relative layout
