45 | circleLayout.addView(View v); 46 | ``` 47 | 3.还可以设置中心的View，这个功能目前只能在代码中设置： 48 | ```java 49 | circleLayout.setCenterView(View v); 50 | ``` 51 | 4.当然，这里还有`remove`和`get`方法，方便使用 52 | 5.如果想在代码中动态设置半径，可以直接调用 53 | ```java 54 | circleLayout.setRadius(int radius); 55 | ``` 56 | 6.可以控制该layout是否可滑动 57 | ```java 58 | circleLayout.setCanScroll(boolean isCanScroll); 59 | ``` 60 | 7.可以手动设置layout旋转角度(也可以在xml中设置) 61 | ```java 62 | circleLyoaut.setChangeCorner(double changeCorner) 63 | ``` 64 | 65 | 8.如果想给每一个子view添加动画啥的，可以直接对子view进行操作 66 | 67 | 9.更多用法请自行脑补 68 | 69 | 70 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | 4 | android { 5 | compileSdkVersion 25 6 | buildToolsVersion "25.0.2" 7 | defaultConfig { 8 | applicationId "com.nelson.circlelayoutdemo" 9 | minSdkVersion 19 10 | targetSdkVersion 25 11 | versionCode 1 12 | versionName "1.0" 13 | testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 14 | } 15 | buildTypes { 16 | release { 17 | minifyEnabled false 18 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 19 | } 20 | } 21 | } 22 | 23 | dependencies { 24 | compile fileTree(include: ['*.jar'], dir: 'libs') 25 | androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 26 | exclude group: 'com.android.support', module: 'support-annotations' 27 | }) 28 | compile 'com.android.support:appcompat-v7:25.3.1' 29 | compile 'com.android.support.constraint:constraint-layout:1.0.1' 30 | testCompile 'junit:junit:4.12' 31 | compile project(':CircleLayout') 32 | } 33 | -------------------------------------------------------------------------------- /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:\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 *;
