如何设置使用默认 Android 图像查看器查看 Bitmap 的意图？

Question

What I am trying to do is to download image from web and show it on screen with zoom/pan capability. I've successfully downloaded image into Bitmap instance, but ImageView doesnt have zooming feature. So instead I'm willing to present it with default viewer which has zoom/pan features.

How do I set up Intent to view Bitmap with default Android image viewer? I know Intents action should be View:

    intent.setAction(Intent.ACTION_VIEW);

But how to provide data for Intent when image is in Bitmap instance myBitmap ?

If you want to use Android default image viewer use below code

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("string Uri")));

or if you want to show Imageview with zoom In/Out functionality refer below question Android Multi touch zooming
