LottieAnimationView (lottie API)

java.lang.Object
- AppCompatImageView
- - com.airbnb.lottie.LottieAnimationView

```
public class LottieAnimationView
extends AppCompatImageView
```
This view will load, deserialize, and display an After Effects animation exported with bodymovin (https://github.com/bodymovin/bodymovin).
You may set the animation in one of two ways: 1) Attrs: R.styleable#LottieAnimationView_lottie_fileName 2) Programatically: setAnimation(String), setComposition(LottieComposition), or setAnimation(JsonReader).
You can set a default cache strategy with R.attr#lottie_cacheStrategy.
You can manually set the progress of the animation with setProgress(float) or R.attr#lottie_progress

public void useHardwareAcceleration(boolean use)
```
    Enable hardware acceleration for this view. READ THIS BEFORE ENABLING HARDWARE ACCELERATION: 1) Test your animation on the minimum API level you support. Some drawing features such as dashes and stroke caps have min api levels (https://developer.android.com/guide/topics/graphics/hardware-accel.html#unsupported) 2) Enabling hardware acceleration is not always more performant. Check it with your specific animation only if you are having performance issues with software rendering. 3) Software rendering is safer and will be consistent across devices. Manufacturers can potentially break hardware rendering with bugs in their SKIA engine. Lottie cannot do anything about that.
  - setAnimation
```
public void setAnimation(int animationResId)
```
    Sets the animation from a file in the raw directory. This will load and deserialize the file asynchronously.
    Will not cache the composition once loaded.
  - setAnimation
```
public void setAnimation(int animationResId,
                         LottieAnimationView.CacheStrategy cacheStrategy)
```
    Sets the animation from a file in the raw directory. This will load and deserialize the file asynchronously.
    You may also specify a cache strategy. Specifying LottieAnimationView.CacheStrategy.Strong will hold a strong reference to the composition once it is loaded and deserialized. LottieAnimationView.CacheStrategy.Weak will hold a weak reference to said composition.
  - setAnimation
```
public void setAnimation(java.lang.String animationName)
```
    Sets the animation from a file in the assets directory. This will load and deserialize the file asynchronously.

    which is more efficient than using a JSONObject. For animations loaded from the network, use {@link #setAnimationFromJson(String)}. If you must use a JSONObject, you can convert it to a StreamReader with: `new JsonReader(new StringReader(json.toString()));`
  - setAnimationFromJson
```
public void setAnimationFromJson(java.lang.String jsonString)
```
    Sets the animation from json string. This is the ideal API to use when loading an animation over the network because you can use the raw response body here and a converstion to a JSONObject never has to be done.
  - setAnimation
```
public void setAnimation(android.util.JsonReader reader)
```
    Sets the animation from a JSONReader. This will load and deserialize the file asynchronously.
    This is particularly useful for animations loaded from the network. You can fetch the bodymovin json from the network and pass it directly here.
  - setComposition
```
public void setComposition(LottieComposition composition)
```
    Sets a composition. You can set a default cache strategy if this view was inflated with xml by using R.attr#lottie_cacheStrategy.

    Plays the animation from the beginning. If speed is < 0, it will start at the end and play towards the beginning
  - resumeAnimation
```
public void resumeAnimation()
```
    Continues playing the animation from its current position. If speed < 0, it will play backwards from the current position.
  - setMinFrame

    Sets the minimum frame that the animation will start from when playing or looping.
  - setMinProgress
```
public void setMinProgress(float startProgress)
```
    Sets the minimum progress that the animation will start from when playing or looping.
  - setMaxFrame
```
public void setMaxFrame(int endFrame)
```
    Sets the maximum frame that the animation will end at when playing or looping.
  - setMaxProgress
```
public void setMaxProgress(float endProgress)
```
    Sets the maximum progress that the animation will end at when playing or looping.
  - setMinAndMaxFrame

                                 float maxProgress)
```
    See Also:
    
    setMinProgress(float), setMaxProgress(float)
  - reverseAnimationSpeed
```
public void reverseAnimationSpeed()
```
    Reverses the current animation speed. This does NOT play the animation.
    
    See Also:
    
    setSpeed(float), playAnimation(), resumeAnimation()
  - setSpeed
```
public void setSpeed(float speed)
```
    Sets the playback speed. If speed < 0, the animation will play backwards.
  - getSpeed
```
public float getSpeed()
```
    Returns the current playback speed. This will be < 0 if the animation is playing backwards.

    Deprecated.
    
    See Also:
    
    setRepeatCount(int)
  - setRepeatMode
```
public void setRepeatMode(int mode)
```
    Defines what this animation should do when it reaches the end. This setting is applied only when the repeat count is either greater than 0 or LottieDrawable.INFINITE. Defaults to LottieDrawable.RESTART.
    
    Parameters:
    
    mode - LottieDrawable.RESTART or LottieDrawable.REVERSE
  - getRepeatMode
```
public int getRepeatMode()
```
    Defines what this animation should do when it reaches the end.
    
    Returns:
    
    either one of LottieDrawable.REVERSE or LottieDrawable.RESTART
  - setRepeatCount
```
public void setRepeatCount(int count)
```
    Sets how many times the animation should be repeated. If the repeat count is 0, the animation is never repeated. If the repeat count is greater than 0 or LottieDrawable.INFINITE, the repeat mode will be taken into account. The repeat count is 0 by default.
    
    Parameters:
    
    count - the number of times the animation should be repeated
  - getRepeatCount
```
public int getRepeatCount()
```
    Defines how many times the animation should repeat. The default value is 0.
    
    Returns:
    
    the number of times the animation should repeat, or LottieDrawable.INFINITE
  - isAnimating
```
public boolean isAnimating()
```
  - setImageAssetsFolder
```
public void setImageAssetsFolder(java.lang.String imageAssetsFolder)
```
    If you use image assets, you must explicitly specify the folder in assets/ in which they are located because bodymovin uses the name filenames across all compositions (img_#). Do NOT rename the images themselves. If your images are located in src/main/assets/airbnb_loader/ then call `setImageAssetsFolder("airbnb_loader/");`.
  - getImageAssetsFolder
```
public java.lang.String getImageAssetsFolder()
```
  - updateBitmap
```
public android.graphics.Bitmap updateBitmap(java.lang.String id,
                                            android.graphics.Bitmap bitmap)
```
    Allows you to modify or clear a bitmap that was loaded for an image either automatically through setImageAssetsFolder(String) or with an ImageAssetDelegate.
    
    Returns:
    
    the previous Bitmap or null.
  - setImageAssetDelegate
```
public void setImageAssetDelegate(ImageAssetDelegate assetDelegate)
```
    Use this if you can't bundle images with your app. This may be useful if you download the animations from the network or have the images saved to an SD Card. In that case, Lottie will defer the loading of the bitmap to this delegate.
  - setFontAssetDelegate
```
public void setFontAssetDelegate(FontAssetDelegate assetDelegate)
```
    Use this to manually set fonts.
  - setTextDelegate
```
public void setTextDelegate(TextDelegate textDelegate)
```
    Set this to replace animation text with custom text at runtime
  - resolveKeyPath
```
public java.util.List<KeyPath> resolveKeyPath(KeyPath keyPath)
```
    Takes a KeyPath, potentially with wildcards or globstars and resolve it to a list of zero or more actual Keypaths that exist in the current animation. If you want to set value callbacks for any of these values, it is recommend to use the returned KeyPath objects because they will be internally resolved to their content and won't trigger a tree walk of the animation contents when applied.
  - addValueCallback
```
public <T> void addValueCallback(KeyPath keyPath,
                                 T property,
                                 LottieValueCallback<T> callback)
```
    Add an property callback for the specified KeyPath. This KeyPath can resolve to multiple contents. In that case, the callbacks's value will apply to all of them. Internally, this will check if the KeyPath has already been resolved with resolveKeyPath(KeyPath) and will resolve it if it hasn't.
  - addValueCallback
```
public <T> void addValueCallback(KeyPath keyPath,
                                 T property,
                                 SimpleLottieValueCallback<T> callback)
```
    Overload of addValueCallback(KeyPath, Object, LottieValueCallback) that takes an interface. This allows you to use a single abstract method code block in Kotlin such as: animationView.addValueCallback(yourKeyPath, LottieProperty.COLOR) { yourColor }
  - setScale
```
public void setScale(float scale)
```
    Set the scale on the current composition. The only cost of this function is re-rendering the current frame so you may call it frequent to scale something up or down. The smaller the animation is, the better the performance will be. You may find that scaling an animation down then rendering it in a larger ImageView and letting ImageView scale it back up with a scaleType such as centerInside will yield better performance with little perceivable quality loss.
  - getScale
```
public float getScale()
```
  - cancelAnimation
```
public void cancelAnimation()
```
  - pauseAnimation
```
public void pauseAnimation()
```
  - setFrame
```
public void setFrame(int frame)
```
    Sets the progress to the specified frame. If the composition isn't set yet, the progress will be set to the frame when it is.
  - getFrame
```
public int getFrame()
```
    Get the currently rendered frame.
  - setProgress
```
public void setProgress(float progress)
```
  - getProgress
```
public float getProgress()
```
  - getDuration
```
public long getDuration()
```
  - setPerformanceTrackingEnabled
```
public void setPerformanceTrackingEnabled(boolean enabled)
```
  - getPerformanceTracker
```
public PerformanceTracker getPerformanceTracker()
```
