Ids should be unique!!! 26 | public String getId(); 27 | public String getName(); 28 | } 29 | ``` 30 | 注意getId()放回的id值必须是独特的，不可重复。 31 | 32 | 2. layout布局 33 | ```xml 34 | 44 | ``` 45 | 46 | 2. 设置标签,使用setLabels()方法 47 | ```java 48 | labelLayout.setLabels(List labels); 49 | ``` 50 | 51 | 3. 添加标签选择监听器 52 | ```java 53 | label_me.setOnCheckChangedListener(new LabelLayout.OnCheckListener() { 54 | @Override 55 | public void onCheckChanged(ILabel label,boolean isChecked) {} 56 | 57 | @Override 58 | public void onBeyondMaxCheckCount() { 59 | 60 | } 61 | }); 62 | ``` 63 | 64 | 4. 如果是需要选择标签，可以调用setMaxCheckCount(int)方法，选中的标签超过这个数checkListener的onBeyondMaxCheckCount()方法会被回调。 65 | 66 | 6. 其它方法 67 | - getCheckedLabelsCount 获取当前被选中的标签数量 68 | - getCheckedLabelIds() 获取被选中的标签的id列表 69 | - getCheckedIdsAsJson() 获取json序列化之后的id的json串 70 | 71 | #### 个性化(可参考默认样式：view_label_common.xml) 72 | --- 主布局 73 | ```xml 74 | 85 | ``` 86 | 87 | --- checkbox_gray.xml 88 | ```xml 89 | 90 | 102 | ``` 103 | 104 | --- 图一中用的CheckBox样式 105 | ```xml 106 | 107 | 115 | ``` 116 | 117 | > ps 118 | > Contact me：lcodecore@163.com 119 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 25 5 | buildToolsVersion "25.0.1" 6 | defaultConfig { 7 | applicationId "com.lcodecore.labellayout" 8 | minSdkVersion 14 9 | targetSdkVersion 25 10 | versionCode 1 11 | versionName "1.0" 12 | testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 13 | } 14 | buildTypes { 15 | release { 16 | minifyEnabled false 17 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 18 | } 19 | } 20 | lintOptions { 21 | abortOnError false 22 | } 23 | } 24 | 25 | dependencies { 26 | compile fileTree(dir: 'libs', include: ['*.jar']) 27 | androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 28 | exclude group: 'com.android.support', module: 'support-annotations' 29 | }) 30 | compile 'com.android.support:appcompat-v7:25.2.0' 31 | compile 'com.android.support.constraint:constraint-layout:1.0.2' 32 | testCompile 'junit:junit:4.12' 33 | } 34 | -------------------------------------------------------------------------------- /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 C:\Users\lcodecore\Applications\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 *;
