Hi Flavien,

Thanks for sharing your code. I try to use it with a webview but facing a problem. There is no header view in a webview ;) I tried to add a padding but padding does not work on webviews. I tried to play with margins but i need to requestLayout and it's a bit laggy.

Any idea ? Thanks

I would like to ask how should I make the images on the header to scroll together with the listView, so that both the bottom and the top of the view will get truncated, and not just the top (as the normal scrolling does).

for example, if the image is: 11 22 33 44 55 then when you scroll, I'd like to get: 22 33 44 instead of: 33 44 55

I've tried to use ParallaxImageView instead of simple ImageViews , but it didn't help.

Also, I've found a tiny bug: you've created a function called "clamp" but its parameters don't match the operations being done there. the minimal value is 1 instead of 0, and the maximal value is 0 instead of 1 : code before:

public static float clamp(float value, float max, float min) {
    return Math.max(Math.min(value, min), max);
    }

code that should be: public static float clamp(final float value, final float min, final float max) { return Math.min(Math.max(value, min), max); }

I've also changed the order of the parameter, since it's more common to put the min value before the max value.

you have to pick the maximum value between "min" and the minimum between "max" and "value"

Hi!

I must say this is an excellent library. There is however one issue, I notice that even though the screen is turned off, the image-swapping still occurs. I was wondering how one could pause the animations without accessing the pause() / resume() animation that were newly added in a recent-ish API? (if I remember correctly? sorry for being so vague, rookie android-dev here :-) )

I tried calling the onAttachWindow() and onDetachWindow() in the main-activity through onResume() and onPause() respectively, by making the classes public instead of protected in your KenBurnsView.java, but alas... no success.

in NoBoringActionBarActivity.Java

mListView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            Toast.makeText(getApplicationContext(), "position" + position,
                    1000).show();

        }
    });

Hi,

As for now the library can swap 2 images. I wanna add support for more than 2 images because I wanna show lots of images. I tried adding it myself but then too it shows only 2 images from the list of tons of images. I guess this is due to array of image views

Hi,

Thanks for this excellent library. I liked this library very much & I have made it much better but now I wanna stop the image from moving but I don't wanna stop from changing the image automatically.

Hi

Thanks for this excellent library. Is there any provision in this library to change the header image dynamically ? For now I've to provide the image ids before only.

Thanks in advance.

• the order of the parameters "max" and "min" is inverted (based on how they are used)
• the method is wrong. it doesn't set the right bounds

ps: sorry its very stupid, but I wanted to fix it!

Hi, I was able to migrate this lib to appcompat and use nineoldandroids to make the needed changes in the scale/transalations animanations, could you add support to it in the original project?

I could open a pull request, but I use eclipse and my code formatting is very different from yours. Anyway, checkout my NotBoringActionBar fork is you want to see what I did. Thanks for this great work!

I took only the kenBurnsView from this project and i implemented it in mine, I this logcat when running it on kitkat devices (on other devices it work perfectly):

hi sir, I've read your blog and code , and it's great. But I got a little problem still bothering me.

public int getScrollY() { View c = mListView.getChildAt(0); if (c == null) { return 0; }

int firstVisiblePosition = mListView.getFirstVisiblePosition();
int top = c.getTop();

int headerHeight = 0;
if (firstVisiblePosition >= 1) {
  headerHeight = mPlaceHolderView.getHeight();
}
return -top + firstVisiblePosition * c.getHeight() + headerHeight;

}

I tried to remove the "firstVisiblePosition * c.getHeight()" and it still work well. So I am still confused about the meaning of this statement.

Thanks for sharing your code. I try to use it with a ActionBarActivity instead of Activity
(NonBoringActivity extends ActionBarActivity) and findViewById(android.R.id.home ) is null findViewById(android.support.v7.appcompat.R.id.home) is null

do you have any idea??
