I have been trying to animate a transition between two fragments. I had originally placed them a property animations in xml (and that didn't really work), then changed it to objectAnimator. For some reason Android Studio is not recognizing the objectAnimator tag.
here is my AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.nick.randomapplication" > <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/Theme.Base.AppCompat.Light" > <activity android:name=".MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> my build.Gradle:
apply plugin: 'com.android.application' android { compileSdkVersion 20 buildToolsVersion "20.0.0" defaultConfig { applicationId "com.example.nick.randomapplication" minSdkVersion 19 targetSdkVersion 20 versionCode 1 versionName "1.0" } buildTypes { release { runProguard false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile "com.android.support:appcompat-v7:20.0.+" } and the xml file:
<?xml version="1.0" encoding="utf-8"?> <objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"> </objectAnimator> Thank you for taking your time to look at this. I'm not sure what to do anymore.

A property animation changes a property's (a field in an object) value over a specified length of time. To animate something, you specify the object property that you want to animate, such as an object's position on the screen, how long you want to animate it for, and what values you want to animate between.
Which of the following options helps you to hold a time value pair for animation in Android? ValueAnimator provides a timing engine for running animation which calculates the animated values and set them on the target objects.
There are two types of animations that you can do with the view animation framework: Tween animation: Creates an animation by performing a series of transformations on a single image with an Animation. Frame animation: or creates an animation by showing a sequence of images in order with an AnimationDrawable .
I think you have placed the xml file in a wrong folder.
valueAnimator objectAnimator and animatorSet resources should be in the folder res/animator, not in res/anim.
