本地历史记录功能的简单说明（详细描述见博客、源码）：
    1.页面布局：主要是在布局文件中使用TagFlowLayout实现流失布局，并通过自定义属性（zhy:max_select="0"）规定标签的最大可选数。
    2.定义从SP中读取历史记录方法：从SP中获取存储的字符串，并通过wy标识将字符串分割为字符串数组，然后添加到List中，最后将list返回。
    3.定义将历史记录写入到SP中方法：先判空，不为空则获取已有的历史记录，再将新的历史记录添加list中，最后把list转换成字符串（添加wy标识）存入到SP中。需要注意的是：1.历史记录最大数量限制，2.历史记录不可重复，3.最新查询的在最前边。
    4.初始化历史记录：先通过本地历史记录判断页面的显示与隐藏，在为FlowLayout填充数据、设置点击事件监听。
    5.点击搜索按钮：首先获取输入框中的内容，然后添加到本地历史记录中，最后再调用initHistory()刷新页面数据。具体的搜索逻辑就不写了，不是重点。
    6.清除历史记录：将本地历史记录置为空字符串，再调用initHistory()刷新页面数据即可，大功告成。 3 | 4 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 25 5 | buildToolsVersion "25.0.2" 6 | defaultConfig { 7 | applicationId "com.wy.flowlayoutusedemo" 8 | minSdkVersion 16 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 | } 21 | 22 | dependencies { 23 | compile fileTree(dir: 'libs', include: ['*.jar']) 24 | androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 25 | exclude group: 'com.android.support', module: 'support-annotations' 26 | }) 27 | compile 'com.android.support:appcompat-v7:25.3.1' 28 | testCompile 'junit:junit:4.12' 29 | compile 'com.hyman:flowlayout-lib:1.1.2' 30 | compile 'com.jakewharton:butterknife:8.8.1' 31 | annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1' 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 C:\Users\ZQZY-102\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 *;
