ImageView displaying in layout but not on actual device

Question

I have an ImageView that I want to display matching the full width of the device, I realized that like this:

Answer 1

I had a problem with a samsung phone not displaying my drawable but it worked fine on another phone. The picture was not in any large dimensions or otherwise abnormal.

To solve this I simply put my picture asset into a drawable subfolder instead of having it in the main drawable folder. E.g from res/drawable to res/drawable-mdpi worked for me. If you have a picture to use for everything not having a specific dpi, put it into res/drawable-nodpi. Here's a bit more about the dpi folders.

Answer 2

I had the same issue and was able to solve it using following.

My problem was that the direction of the drawable archive was wrote in the second scrCompact box.

I copy-pasted in the up box and the issue solved.

Answer 3

Alright I've tried changing the resolution of the image (cutting it in half making it 1000x130), and somehow that fixed the problem. I think Android can't render large images like that directly? I don't know, if you know more about the subject please don't hesitate to reply! Anyway, scaling down the image worked.

Answer 4

For my case, I change the scale type of the image

android:scaleType="fitXY"

Answer 5

None of the above did the trick, it was a really big image, found this solution: In your manifest file

<application
        //this solve it for me.
        android:hardwareAccelerated="false"
        // Add this if the previuos line didn't solve tge problem
        android:largeHeap="true"
        android:theme="@style/AppTheme">

Solve it for me.

Hope it helps someone.

Answer 6

For me, the problem was that I was using

tools:src=...

rather than

android:src=...

It got auto-generated trying to use an already existing template image.
