My xml in this part is roughly like this:

 <com.daimajia.androidviewhover.BlurLayout
        android:id="@+id/blur_layout"
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="1">

        <FrameLayout
            android:id="@+id/fragment_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            />
    </com.daimajia.androidviewhover.BlurLayout>

And I want to through the menu key to showHover (), the results originally expected is this: I press the Menu key, then Hover out, covering my entire FrameLayout. The result is not, and the error (key information) as follows:

Caused by: java.lang.NullPointerException

So ask: under BlurLayout in the layout file has one and only ImageView? I put a FrameLayout, and want the buttons to control Hover‘s toggle, but it seems not, could help? Thank you very much!

mSampleLayout.addChildAppearAnimator(hover, R.id.heart, Techniques.FlipInX);在addChildAppearAnimator方法中都提示：The method addChildAppearAnimator(View, int, Techniques) from the type BlurLayout refers to the missing type Techniques。 好像说缺失Techniques类型，但是确实我什么也没有改呀。

I've been trying to add this library to my project but I'm either too dumb to use it or there is a bug that seems to only affect my project...

This is my Code to show the HoverView:

View newView = mInflater.inflate(R.layout.card_back, null); BlurLayout oldView = (BlurLayout) mNowLayout.findViewById(id); oldView.setHoverView(newView); oldView.setBlurDuration(500); //Adding Animations oldView.showHover();

My actual problem is visible in the attached picture. As you can see there is the blurred version of the text & images underneath an unblurred version of the text & images. It might just be me doing something wrong but if that is the case I'm absolutely clueless about what I'm doing wrong.

I recently finished my app using AndroidViewHover which shows icons over a CardView. I test it on android 2.3, 4.0 and 4.4 and works fine. But one of my customer complaining that icons dont show up on LG G3 using android 5.0

Any idea?

Is there a way to know when dismissHover Animation Completes? I really need something like onDismissHoverAnimationComplete If there is a way please show it to me. Thanks.

@daimajia can i exclude nineolddroid from my build gradle file as i wont require it because my project is API14 and above.If i does not include it,shows a error as class cast exception cannot inflate blur layout.Help!

Allow for changes to the blur radius. Allow us to disable the touch event so that we can have it trigger via a button or other event. Recycle the bitmap.

I want to use OnLongClickListener.

I put an imageview inside the cardview and applied a blurview.

I applied longclick to Cardview. But when I clicked on the imageview, longclick didn't work.

I want to make longclick work when I hit the area of ​​Cardview. However, imageview has blurview, so it does not work in imageview area.

So I tried applying OnLongClickListener to the imageview to solve this.

But when I use OnLongClickListener for imageview, blurview doesn't work.

Please tell me the solution.

Hey I used API 24 try using API 23 but got this error when I click

在对图片进行高斯模糊处理的Blur.java文件中，进行模糊之前先将要模糊的图片尺寸缩小，再对缩小的图片进行模糊处理，最后将图片放大，这样相比之前对图片处理的时间会缩小一半，而且模糊效果也会更加明显，理论上说ScriptIntrinsicBlur进行模糊的范围只能从0~25，而使用图片的尺寸缩放后进行模糊处理能突破这个范围的限制。
