500px / 500px-android-blur Goto Github PK

I am using blur view in a fragment.

For example in the fragment layout,

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
....
tools:context="fragments.FeedFragment">

<android.support.v4.widget.SwipeRefreshLayout
 ...>

    <com.github.yasevich.endlessrecyclerview.EndlessRecyclerView
        android:id="@+id/feedList"
  ..../>

</android.support.v4.widget.SwipeRefreshLayout>

<FrameLayout android:id="@+id/emptyState"
      .../>

</FrameLayout>

<!-- Here, we customize the blurring view with values different from the defaults. -->
<com.fivehundredpx.android.blur.BlurringView
    android:id="@+id/blurring_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:blurRadius="11"
    app:downsampleFactor="7"
    app:overlayColor="#99FFFFFF"/>

And in the Fragment,

I do in the onActivityCreated, I use

        mBlurringView.setBlurredView(getView().findViewById(R.id.feedList));

I also call this in the onResume just to make sure, its setting the view.

But the issue is that sometimes I see the blur, sometimes, I dont see anything ? Am I missing anything ?
Ofcourse I am also calling mBlurringView.invalidate();

I am using the fragment in a view pager

I really really want to thank you for this. This is exactly what I needed however I can't seem to animate alpha from 0 to 1.

This code can fit directly into your sample to show you the problem.

public void shuffle(View view) {
final AlphaAnimation animation1 = new AlphaAnimation(0.1f, 1.0f);
animation1.setDuration(1000);
animation1.setStartOffset(1000);

    animation1.setAnimationListener(new Animation.AnimationListener() {

        @Override
        public void onAnimationEnd(Animation arg0) {
            blurrHolder.invalidate();
            blurrHolder.setAlpha((float) 1);
        }

        @Override
        public void onAnimationRepeat(Animation arg0) {
            blurrHolder.invalidate();
        }

        @Override
        public void onAnimationStart(Animation arg0) {
            blurrHolder.invalidate();
        }
    });

    mBlurringView.startAnimation(animation1);
}

is it because render script was deprecated?

did I do something wrong ? My API is 21-23

When I use proguard with minifyEnabled option I get this fatal crash on launch:

java.lang.RuntimeException: Unable to start activity ComponentInfo{...}: android.view.InflateException: Binary XML file line #67: Error inflating class com.fivehundredpx.android.blur.BlurringView

But with minifyEnabled turned off, it works fine.

Are there any proguard rules I need to add?

I want use on a MediaPlayer,but it is a Surface.

and i can't linsten the frame changed.

I tried this library and it's looking promising, but it doesn't work with ArcGIS maps, which I would like to blur. Could you have a look and/or give advise? I have modified your example to ilustrate problem.

I have already add the
"renderscriptTargetApi 20"
"renderscriptSupportModeEnabled true"
in my gradle file . but i still got that error ，why?

https://stackoverflow.com/questions/59376376/how-i-can-use-blur-with-webview

hi, i user the bluring_view on the imageview, first time open the layout, the blurview show white[no half transparent]; the second time open the layout, it show normal [half transparent]

can you show me what happen to it

I put:

dependencies {
    compile 'com.fivehundredpx:blurringview:1.0.0'
}

in the gradle file but it says "Failed to resolve: com.fivehundredpx:blurringview:1.0.0"

Am I doing something wrong?

why?

The library works perfectly but when I apply a blur effect on a listview, it display a weird result, so is it possible to replace a color with an other color (in this case blue by gray) for not showing divider of listview ?

App crashed in some cellphones with the api below level 19.

If I use BlurringView and then go to another activity, and them come back to the previous activity. The Blurred image disappears.

Is it possible to make the BlurringView blur everything that's beneath it? (Not only its sibling views.)

I've been spending some time fixing up the react-native-blur library, which is not great on Android. The docs need some updates, but right now their suggested usage works on iOS, and can cause an infinite loop on Android.

I think it might be a good idea to add a check in BlurringView, to make sure that there are no circular references that would cause an infinite loop (where the BlurringView is trying to to draw itself).

Not just for React Native developers, but for any other Android developers who might do this by accident, and wonder why their app is just freezing before crashing from a stack overflow.

I don't have a ton of experience with Android, but I can try to submit a PR if you think this is a reasonable idea.

I'm facing a weird behavior on blur with Android 9, the blurAmount is set to 1 and type light, on emulators this works properly, on Android 9 physical device the blur is pixelated.

Use isInEditMode() condition in your customs view for properly browsing in Android Studio Layout editor

First, thanks for this great library!

I'm using your BlurringView to blur a full screen image in my app, but I'm getting artifacts at the edge of the screen where the image isn't blurred. I read in your blog post that you added the lines:

scaledWidth = scaledWidth - (scaledWidth % 4) + 4;
scaledHeight = scaledHeight - (scaledHeight % 4) + 4;

to remove artifacts at the edges of the view, but for me, removing those two lines removed the artifacts. Is it safe to remove those lines? Do the artifacts depend on the image, the device, the downsample factor, or the blurring radius?

Hello,

I was trying to use your blur view in my app insde items displyed in RecyclerView. Unfortunatly, after my recycler is scrolled (up or down) for few items I get following exception:

android.support.v8.renderscript.RSInvalidStateException: Calling RS with no Context active.
at android.support.v8.renderscript.ExceptionThunker.convertException(ExceptionThunker.java:26)
at android.support.v8.renderscript.AllocationThunker.copyFrom(AllocationThunker.java:183)

It is thrown from blur method. To me it looks like this is caused by items being recycled and reused by RecycleView. For current moment I haven't found any solution for this.

Was Renderscript Support mode tried? it's v8 and easy to enable in the build script

defaultConfig{
..
renderscriptTargetApi 21
renderscriptSupportModeEnabled true
..
}
