32 | 33 | where "masterRef" is a shared AtomicReference variable that's used to decide which of them is the current "master" to affect the others. 34 | 35 | Example of 2 ViewPagers, each can affect the other: 36 | 37 | AtomicReference masterRef=new AtomicReference<>(); 38 | viewPager.addOnPageChangeListener(new ParallaxOnPageChangeListener(viewPager,viewPager2,masterRef)); 39 | viewPager2.addOnPageChangeListener(new ParallaxOnPageChangeListener(viewPager2,viewPager,masterRef)); 40 | 41 | 42 | Known issues 43 | ------------ 44 | Sometimes, the other ViewPager might have a "flashing" effect. 45 | A workaround for this, is to pass the touch events from the container of the various viewpagers, to the master viewpager. 46 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/app.iml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 8 | 9 | 10 | 11 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | 98 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 22 5 | buildToolsVersion "23.0.0 rc2" 6 | 7 | defaultConfig { 8 | applicationId "lb.com.parallaxviewpagers" 9 | minSdkVersion 7 10 | targetSdkVersion 22 11 | versionCode 1 12 | versionName "1.0" 13 | } 14 | buildTypes { 15 | release { 16 | minifyEnabled false 17 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 18 | } 19 | } 20 | } 21 | 22 | dependencies { 23 | compile fileTree(include: ['*.jar'], dir: 'libs') 24 | compile 'com.android.support:appcompat-v7:22.2.0' 25 | compile project(':parallax_view_pagers_library') 26 | } 27 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # By default, the flags in this file are appended to flags specified 3 | # in D:\AppData\Local\Android\Sdk/tools/proguard/proguard-android.txt 4 | # You can edit the include path and order by changing the proguardFiles 5 | # directive in build.gradle. 6 | # 7 | # For more details, see 8 | # http://developer.android.com/guide/developing/tools/proguard.html 9 | 10 | # Add any project specific keep options here: 11 | 12 | # If your project uses WebView with JS, uncomment the following 13 | # and specify the fully qualified class name to the JavaScript interface 14 | # class: 15 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 16 | # public *;
