Semi-transparent Textureviews Not Working

I cannot change the transparency of a TextureView by setAlpha method to maske it semi-transparent as it is promised by the android SDK. For example mTextureView.setAlpha(0.5f) does

Solution 1:

You need to make sure and setOpaque(false).

From the docs:

public void setOpaque (boolean opaque) Added in API level 14

Indicates whether the content of this TextureView is opaque. The content is assumed to be opaque by default.

Solution 2:

The solution I used to make it happen was to wrap the TextureView in another widget like RelativeLayout and change the transparency of the parent.
