27 | 28 | 另需要设置主题@style/AppTheme.Slide以便滑动时使下层Activity可见 29 | 此外还提供了无ActionBar的主题@style/AppTheme.Slide.NoActionBar: 30 | 31 | 例，如下设置：不需要使用滑动返回的Activity（如MainActivity）,则单独设置主题 32 | 33 | ```xml 34 | 40 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | ``` 50 | 51 | #### 重写Activity的onSlidingBack()方法,处理滑动返回销毁Activity前的工作，例如需要setResult、释放资源等工作 52 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.library' 2 | 3 | android { 4 | compileSdkVersion 26 5 | buildToolsVersion '26.0.2' 6 | 7 | defaultConfig { 8 | minSdkVersion 19 9 | targetSdkVersion 26 10 | versionCode 1 11 | versionName "1.0" 12 | } 13 | buildTypes { 14 | release { 15 | minifyEnabled false 16 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 17 | } 18 | } 19 | compileOptions { 20 | encoding "UTF-8" 21 | } 22 | } 23 | 24 | dependencies { 25 | compile fileTree(dir: 'libs', include: ['*.jar']) 26 | compile 'com.android.support:appcompat-v7:26.1.0' 27 | } 28 | 29 | ext { 30 | bintrayRepo = 'maven' 31 | bintrayName = 'edgeslidingback' 32 | 33 | publishedGroupId = 'com.geejoe' 34 | libraryName = 'EdgeSlidingBack' 35 | artifact = 'edgeslidingback' 36 | 37 | libraryDescription = 'An Android library help app with edge sliding back like ios' 38 | 39 | siteUrl = 'https://github.com/GeeJoe/EdgeSlidingBack' 40 | gitUrl = 'https://github.com/GeeJoe/EdgeSlidingBack.git' 41 | 42 | libraryVersion = '1.0.7' 43 | 44 | developerId = 'geejoe' 45 | developerName = 'GeeJoe' 46 | developerEmail = 'geejoe_developer@outlook.com' 47 | 48 | licenseName = 'The Apache Software License, Version 2.0' 49 | licenseUrl = 'http://www.apache.org/licenses/LICENSE-2.0.txt' 50 | allLicenses = ["Apache-2.0"] 51 | } 52 | 53 | apply from: 'https://raw.githubusercontent.com/nuuneoi/JCenter/master/installv1.gradle' 54 | apply from: 'https://raw.githubusercontent.com/nuuneoi/JCenter/master/bintrayv1.gradle' -------------------------------------------------------------------------------- /edgeslidingback.iml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 8 | 9 | 10 | 11 | 24 | 25 | 26 | 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 | 99 | 100 | 101 | 102 | 103 | 104 | 105 | 106 | 107 | 108 | 109 | 110 | 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | 127 | 128 | 129 | -------------------------------------------------------------------------------- /gif/2017-06-04_20_09_56.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/GeeJoe/EdgeSlidingBack/8e795297a92def288f74390c1e89592775c5ee37/gif/2017-06-04_20_09_56.gif -------------------------------------------------------------------------------- /gif/2017-06-04_20_28_44.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/GeeJoe/EdgeSlidingBack/8e795297a92def288f74390c1e89592775c5ee37/gif/2017-06-04_20_28_44.gif -------------------------------------------------------------------------------- /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 C:\MyPrograms\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 *;
