Use Bitmap as source instead of URL

[adrissacf]

Is it possible to use a bitmap as the source, since i download my images from a database and get them as a byte array which i decode to a bitmap.

Edited the BaseSliderView class in the library project to the following, and then you can just use a bitmap like

DefaultSliderView defaultSliderView = new DefaultSliderView(getBaseContext()); defaultSliderView.image(bmp); sliderShow.addSlider(defaultSliderView);

Updated BaseSliderView class:

package com.daimajia.slider.library.SliderTypes;

import android.content.Context; import android.graphics.Bitmap; import android.os.Bundle; import android.view.View; import android.widget.ImageView;

import com.daimajia.slider.library.R; import com.squareup.picasso.Callback; import com.squareup.picasso.Picasso; import com.squareup.picasso.RequestCreator;

import java.io.File;

same question for me can you use it?

[meness]

Can you fork this repository and make the improvement please?

[positivelymade]

Solution above worked!

I've had this:

"Cannot resolve method 'bundle(android.io.Bundle)"

Just need to add bundle method:

public BaseSliderView bundle(Bundle bundle){ mBundle = bundle; return this; }

This is a useful solution. Thank you.
