Custom Subsampling Scale Image View about bigimageviewer

Checkout v1.3.1

Why do we need this?

[HR]

I need to override SubsamplingScaleImageView's protected void onSizeChanged(int w, int h, int oldw, int oldh) method in order to change its default device orientation behaviour (which is flawed)

[Piasy]

I think we can add a setSSIV method to BigImageView, which will add the provided SSIV as its first child, then we can add a useExternalSSIV attribute(boolean), which means it should not create a SSIV itself. Waiting for your PR :)

[HR]

OK but what about the AttributeSet (i.e. attr at init) required by the custom Subsampling Scale Image View to initialise since its constructor is SubsamplingScaleImageView(Context context, AttributeSet attr)?
You can not cast the BigImageView XML view into a CustomSubsamplingScaleImageView

[Piasy]

Oh I got it, as BigImageView is a FrameLayout, maybe we could just declare a custom SSIV in layout xml file, then we only need useExternalSSIV attribute(maybe name it useXmlSSIV is better), please try that.

[HR]

I'm not sure how that would solve the problem since I need to instantiate a CustomSubsamplingScaleImageView class not resource.

[Piasy]

Declare it in layout xml file, use it as SSIV instance needed by BIV.

[HR]

So use it like

CustomSSIV customSSIV = (CustomSSIV) findViewById(R.id.CustomSSIView);
BigImageView bigImageView = new BigImageView();
bigImageView.setSSIV(customSSIV);
bigImageView.showImage(Uri.parse(url));

[Piasy]

No, findViewById call should happen in BIV constructor, and also we don't need an extra boolean attribute. If we find a SSIV, then use it, else we new a SSIV.

[HR]

Then how would you pass your custom SSIV class to BigImageView ?

[Piasy]

With my last comment, we've already done.

[HR]

I'm still not sure how you would specify a custom SSIV class since what you seem to be talking about is a custom SSIV layout

Can you please provide examples to clarify things?

[Piasy]

See this commit :)

[HR]

Awesome! It works. Can you please merge and release ASAP?

[Piasy]

Sure :)
