有没有办法只选择 ImageView 和 Textview 的内容并将它们下载为图像文件以保存在设备存储中？

Question

I want to create a download button so that users can download the contents of the ImageView and TextViews (which is on top of the ImageView) as an image file and save it in the device storage.

Here is the code block:

    <ImageButton
    android:id="@+id/back_btn"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:background="@mipmap/ic_back"
    android:layout_marginTop="20dp"/>

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/quotes_background"
        android:layout_centerInParent="true"/>

    <TextView
        android:id="@+id/quoteBody"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:textSize="20sp"
        android:typeface="monospace"
        android:textColor="@color/white"
        android:gravity="center"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"/>

    <TextView
        android:id="@+id/author"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:textSize="25sp"
        android:layout_below="@id/quoteBody"
        android:textColor="@color/white"
        android:layout_marginTop="20px"
        android:gravity="center"/>

I just want to select the ImageView and the two TextViews and download them as an image (PNG). Any help will be appreciated.

Thank You.

What you probably want is to save a Bitmap of what you see on the screen. See this answer .
