shimmer-android's Issues

Move raw mission statement string to string resource

The current mission statement in the main.xml layout is hardcoded. It should instead be moved over to the strings.xml file and referenced correctly in main.xml

ListView animation freezes

Every time I use the widget in a ListView with more than 3 or 4 items using the viewholder pattern, the list items after that 3rd or 4th item does not animate.

I've tried to startAnimation programatically and also tried setting the app:auto_start attribute to true in the layout's attributes.

Shimmering does not stop after calling .stopShimmer()

Hello I would like to ask why is shimmering still exist even after calling .stopShimmer() method in RecyclerView. Here's an example I am using 0.2.0 v.

        //Set the user's profile picture
        this.shimmerSUDP.startShimmer();
        GlideApp.with(context)
                .load(thumbnail)
                .placeholder(R.color.icon_not_selected)
                .diskCacheStrategy(DiskCacheStrategy.AUTOMATIC)
                .listener(new RequestListener<Drawable>() {
                    @Override
                    public boolean onLoadFailed(@Nullable GlideException e, Object model, 
                            Target<Drawable> target, boolean isFirstResource) {
                        return false;
                    }

                    @Override
                    public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> 
                      target, DataSource dataSource, boolean isFirstResource) {
                        shimmerSUDP.stopShimmer();
                        return false;
                    }
                })
                .into(mSuDP);

Clear Shimmer

I have an image view inside a shimmer frame layout, when load an image into the image view I want to clear the shimmer entirely but there is no way to do this. If I stop the shimmer there is still an overlay over my image view.

Xamarin binding

Will there be a Xamarin Android binding available?

Error inflating class com.facebook.shimmer.ShimmerFrameLayout

used jar instead of adding it as compile statement in dependencies. worked fine in demo. but not working in project. Bcause adding dependency was giving me Error:(593) Attribute “shape” already defined with incompatible format this error.

java.lang.RuntimeException: Unable to start activity ComponentInfo
android.view.InflateException: Binary XML file line #41: Binary XML file line #41: Error inflating class com.facebook.shimmer.ShimmerFrameLayout.

The shimmer is drawn at an incorrect position

To make this noticeable:

1. Don't set Xfermode on mShimmerPaint to see where mDrawRect is drawn.
2. Decrease ShimmerLayout height.
3. Increase tilt angle to 40 or more.

RTL support

is there a way to make the shimmer effect from Right To Left?

auto_start stopped working with AndroidStudio 3.0

Also, when calling startShimmerAnimation() from inside the code, the animation makes the shimmer layout transparent

app becomes jerky with shimmer

I have a gridlayout that i use as placeholder while i load some data, and I used shimmer to animate it.

If I surround the gridlayout with a ShimmerFrameLayout, then the phone becomes very jerky and stutters a lot when the anim is happening. If I enable GPU profiling you can see very long blue bars indicating heavy animation work.

Is this expected? How are other apps dealing with this?

This is how im using it:

ShimmerFrameLayout With Scrollview

Hor to use ShimmerFrameLayout with scrollview properly ?

        android:layout_gravity="center"
        android:orientation="vertical"
        shimmer:duration="1500">

        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fillViewport="true">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"

    </com.facebook.shimmer.ShimmerFrameLayout>

But My View looks like this when i scroll :

Please add my app to the list

Hey there, I'm using Facebook Shimmer in my Twitter client Spreadsheet!

Might you add it to the list, please?

Thanks!

If a View call animat to scale quality will be very low

ShimmerFrameLayout inside ShimmerFrameLayout issue

In case you have ShimmerFrameLayout (outer) inside ShimmerFrameLayout (inner), and you start shimmer for inner view - it also starts shimmer for outer view (at least animate it). Could you please check this?

Applying ShimmerFrameLayout to an elevated View in Lollipop "multiplies" the shadow

It seems that applying the Shimmer-magic to a view does draw lollipop elevation-shadow multiple times.
In the picture below I made a screenshot of a FAB with and without being nested in a ShimmerFrameLayout.
Did you ever encounter that? Any ideas to fix this?

Add customizable preset to sample app

It would be great if the sample app had the ability to tweak the various properties of the shimmer dynamically and interactively.

There should be an additional preset called "Custom" that will show a bunch of controls for each of the possible options for the shimmer object. Once a value is changed, the shimmer should be updated so you could see the new effect.

Relative width, height and a few other attributes cannot be set because they need floats but setters are typed as Ints

I can't set the relative width:

        app:relative_width="0.3"

java.lang.UnsupportedOperationException: Can't convert value at index 9 to dimension: type=0x4
   at android.content.res.TypedArray.getDimensionPixelSize(TypedArray.java:720)
  at com.facebook.shimmer.ShimmerFrameLayout.<init>(ShimmerFrameLayout.java:226)
   at com.facebook.shimmer.ShimmerFrameLayout.<init>(ShimmerFrameLayout.java:147)
                                                                                     	... 33 more

Looking at the source, this is because the setter inexplicably takes an int and casts it to float, instead of taking a float in the first place.

 public void setRelativeWidth(int relativeWidth) {
    this.mMask.relativeWidth = (float)relativeWidth;
    this.resetAll();
  }

This should be an easy fix. I'd open a PR myself if I didn't have a deadline to meet.

[Feature Request] support for delayed stopping

There should be an option/feature to stop the animation/visibility that waits a minimum time to be dismissed. It should be visible/animate for a minimum amount of time to avoid "flashes" in the UI.

Severe tearing in animations

If the shimmer effect is applied to a view that is taller than it is wide in the travel direction of the shimmer a severe tearing effect can be seen.

To visualize this you can test the following layout in portrait & landscape:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:id="@+id/shimmer_test"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

                  android:layout_height="0dp"
                  android:layout_weight="2"
                  android:orientation="horizontal">

        </com.facebook.shimmer.ShimmerFrameLayout>

            android:layout_weight="1"
            app:auto_start="true"
            app:angle="cw_90">

        </com.facebook.shimmer.ShimmerFrameLayout>
    </LinearLayout>

    <View
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>
</LinearLayout>

basically, it will look like this:

Shimmer Getting Stopped Inside RecyclerView When Scrolling

Hello,
Shimmer works like a charm in my project but there's a little problem. as i am using shimmer inside my recyclerview its getting stopped animating when i scrolled :(

A simple video of that problem -> Video_Of_Stopping Shimmer [20 Sec]

Note: I applied shimmer in nested recyclerview.
Here's my snippet(for simplicity i just added meaningful code).

Inside MyAdapter

public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
......................................
 switch (holder.getItemViewType()) {
 case ViewType.LATEST_MOVIE:
                final LatestMovieViewHolder latestMovieViewHolder = (LatestMovieViewHolder) holder;
                latestMovieViewHolder.titleMovie.setText("Latest Movie");
                latestMovieViewHolder.shimmerFrameLayout.setVisibility(View.VISIBLE);
                latestMovieViewHolder.shimmerFrameLayout.startShimmerAnimation();
                latestMovieViewHolder.sectionRecylerView.setLayoutManager(new LinearLayoutManager(context, OrientationHelper.HORIZONTAL, false));
                latestMovieViewHolder.sectionRecylerView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
                RetrofitRequestAPI retrofitRequestAPI = MyRetrofit.getRetrofitInstance().create(RetrofitRequestAPI.class);
                Call<List<Movie>> requestObject = retrofitRequestAPI.getMoviesInTheater();
                requestObject.enqueue(new Callback<List<Movie>>() {
                    @Override
                    public void onResponse(Call<List<Movie>> call, Response<List<Movie>> response) {
                        if (response.body() != null) {
                            latestMovieViewHolder.shimmerFrameLayout.stopShimmerAnimation();
                            latestMovieViewHolder.sectionRecylerView.setVisibility(View.VISIBLE);
                            latestMovieViewHolder.shimmerFrameLayout.setVisibility(View.GONE);
                            latestMovieViewHolder.sectionRecylerView.setAdapter(new SectionAdapter(context, response.body()));
                        }
                    }

                    @Override
                    public void onFailure(Call<List<Movie>> call, Throwable t) {
                        Toast.makeText(context, t.getMessage(), Toast.LENGTH_LONG).show();
                    }
                });
                break;
............................`


**And here XML** 

`
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    <!--------------------other staff>

    <com.facebook.shimmer.ShimmerFrameLayout
        android:id="@+id/shimmerView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="gone">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
            <include layout="@layout/recyler_view_shimmer" />
            <include layout="@layout/recyler_view_shimmer" />
            <include layout="@layout/recyler_view_shimmer" />
        </LinearLayout>
    </com.facebook.shimmer.ShimmerFrameLayout>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/singleSectionRecylerView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

```

Migration to AndroidX

With Google introducing AndroidX, is migration to AndroidX on the roadmap for this project?

Memory leak

I am seeing the following with LeakCanary - I think it is because I am exiting the activity while there is some animation thread running. What is the possible solution for this?

Latest gradle version

Looks like the latest commit reduce the min-sdk requirement. Awesome. When will it get pushed to maven?

Translate shader instead of drawing a rect

We can remove a draw call if we just translate the shader used to compose the view instead of drawing a shaded rect.

remove mask after animation ends

maybe you should add autoStop property to shimmer
when repeat count reached, it will remove the mask.

Add CONTRIBUTING file

Add contributing file to detail how to work on the project (first time setup, etc).

Out of memory!!!

Is there any configuration to handle out of memory? This issue not belong to size of image that containing by container...

Smart quotes in code example

I'll admit this is a pretty dumb ticket, but it's worth pointing out that the code examples on the webpage can't be copy-pasted due to smart quotes used in the code examples:

https://github.com/facebook/shimmer-android/blob/gh-pages/index.html#L95

Pasting this into Android Studio makes the IDE think the wrong closing tags are used, attributes aren't defined, and other totally non-useful errors ;)

Seems like an easy fixed. I'd send over a PR but I think my contract may prevent me from doing so

Shimmer not working for certain tablets

The Shimmer implementation seems not to work for certain devices (like HUAWEI MediaPad M3 Lite 10). I am using the ShimmerFrameLayout (auto_start = false) and start the shimmer using .startShimmer()

how can i change the colour of the shimmer light

i want to create a view which has a bright-white light over the whole view , but when i used this library , the color of the shimmer light always depends on the color of the view's background ,for example , when a view'background is yellow ,the shimmer light is yellow too , but what i want is that the colour of the shimmer light is brght white. how can i make this?

Not working in MIUI

I am using this library: https://github.com/sharish/ShimmerRecyclerView which depends on facebook shimmer library.
The adapter part is working fine but shimmer (by facebook is not woking at all).
Please fix.
BTW, perfectly working on stock android (My Moto E 2nd Gen Android API 21)

Problem on: MIUI Redmi 3S Prime Android API 23 MIUI Version Global 8.1 (8.1.1.0 MALMIDI)

Error:(471) Attribute "shape" already defined with incompatible format.

I am trying to include the gradle dependency into my app. After adding the dependency and rebuilding the app it is giving the above mentioned issue. Please let me know how to fix this issue.

Crashing with NPE in Espresso tests.

App is crashing consistently while running espresso tests.

Publish a new version

Shimmer animation is not working properly in version 0.1.0. I cloned the repository and the bug was fixed when I tried it.
Could you release version 0.2.0?

How to exclude some views

Hi,

Looking at the documentation I didn't found a way to exclude some views from the animation. Is there a way to achieve this without having multiple shimmers ?

Here is what I'd like to have with Separator and TextView not animated :

<ShimmerL>
<ConstraintL>
<View>
<View>
<Separator>
<TextView>
<View>
<View>
</ConstL>
</Shimmer>

The thing is with a complex layout it's nice to flatten it with constraint layout. Having (multiple) ShimmerLayout inside my constraint layout remove the ability to setup constraint within childs views.

SDK level requirement 16 because of the included example project.

The library itself requires sdk level 11 as minimum but, the included sample project sets the minimum sdk to 16. This causes including the library to set the minimum level to 16, when it can be done in api level 11.

In the new android studio 3.0. I am getting this exception with the shimmerlayout

i did follow the commit of removing the shimmer:animation and trying to take off the constraint layout as well . Stil its same . please help . The error is not resolved for me . i did see the issue #20 closed . But whats the solution to this ?

startShimmer() and stopShimmer() are not starting or stopping the animation view

I have implemented the library, but this two scenarios are happening;
First, when the view comes up the shimmer animation starts automatically, but when I call mShimmerFrameLayout.stopShimmer() it does not stop it.
Secondly, when autoStart is disabled in the layout attribute and the view comes up, if I call mShimmerFrameLayout.startShimmer(), it does not start the animation.

Please a solution is needed.
