DoubleClickHelper .getInstance() .delayTime(500) //间隔时间 .addAnnotationClass(UnifiedDoubleClick.class) //自定义属性, 可叠加 .addAnnotationClass(UnifiedDoubleClick2.class); } } ``` ``` public interface UnifiedDoubleClick{ //用户自定义接口 // >>>>>>>>>>>>>>>>>>>屏蔽DoubleClick的Activity>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> // @ACancelActivity(activitys = { // MainActivity.class, // }) // void cancelActivity(); // >>>>>>>>>>>>>>>>>>>单个view处理>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> @AAddDoubleClick(activity = MainActivity.class, addIds = {R.id.btn1, R.id.btn2}, times = {0, 2000}) //点击的间隔时间 void mainActivity(); // >>>>>>>>>>>>>>>>>插入自定义clickListener>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> @AClickListener(activity = MainActivity.class, lisenner = LoginClickListener.class, //自定义clickListener ids = {R.id.btn2}) void interceptMain(); } ``` ``` public class LoginClickListener implements IOnClickListener { public static boolean isLogin = false; @Override public boolean isNext(View v) { //判断登录逻辑 if(!isLogin){ LogUtil.d("未登录"); Toast.makeText(v.getContext(), "未登录", Toast.LENGTH_SHORT).show(); } return isLogin; } @Override public void after(View view) { //执行click后 } } ``` **扩展---可调用方法** ``` DoubleClickHelper.openAll(); //开启 DoubleClickHelper.closeAll(); //关闭 //(可选)用hook方式处理单个view, 时间会和上面的时间叠加, 一般使用场景: Activity只有个别按钮需要doubleClick DoubleClickHelper.hookView(View view, long delayTime); ``` # 三.历史版本: **V3.0.0:** 使用AOP的方式处理, 使用方式和2.0基本一样, 比2.0的方式性能更好. [V2.0版本](https://github.com/liys666666/DoubleClick/blob/master/README2.0.6.md). [V1.0版本](https://github.com/liys666666/DoubleClick/blob/master/README1.0.4.md) * 如果框架中存在不足或者有什么建议, 欢迎指出, 我这边会尽快处理, 让框架更完善, 希望这个框架能帮助更多人, 如果觉得好用, 欢迎star. ================================================ FILE: README1.0.4.md ================================================ # DoubleClick # 一. 基本使用 框架主要有两个功能(基本用法): **1. 无入侵解决按钮重复点击.** [使用方法](https://www.jianshu.com/p/7f3e5c8b8643) **2. onClick重复逻辑统一处理.** [使用方法](https://www.jianshu.com/p/b4038a2d68eb) **① 导入框架** ``` //项目根目录下,build.gradle allprojects { repositories { ... maven { url 'https://jitpack.io' } //添加 } } ``` ``` //app目录下build.gradle dependencies { implementation 'com.github.liys666666:DoubleClick:V1.0.4' //添加 } ``` **② 自定义的Application初始化即可** ``` public class AppApplication extends Application{ @Override public void onCreate() { super.onCreate(); ViewDoubleHelper.init(this); //默认时间：1秒 // ViewDoubleHelper.init(this, 2000); //自定义点击间隔时间(单位：毫秒) } } ``` # 二.扩展: **V.1.0.2(包含)以上** 1. onClick重复逻辑统一处理--添加新写法(可选): 建议先看基本用法: [onClick重复逻辑统一处理](https://www.jianshu.com/p/b4038a2d68eb) ``` public class MainActivity extends AppCompatActivity implements IAddCustomHookClick{ @Override public List getCustomHookList() { int[] ids = {R.id.btn1, R.id.btn2}; //需要处理的id List list = new ArrayList<>(); for (int i = 0; i < ids.length; i++) { //添加 list.add(new CustomHookBean(ids[i], new LoginClickListener())); } return list; } } ``` 2. 如果有更好的具体实现方法, 也可以自己实现, 具体做法, 其它不变, 在AppApplication是添加: ``` //连续重复点击多次, 自定义具体实现 // ViewDoubleHelper.setIViewDoubleClick(new IViewDoubleClick() { // @Override // public void hookActivityViews(Activity activity, long delayTime) { // //hook Activity内所有View // } // // @Override // public void hookResView(Activity activity, int viewResId, long delayTime) { // //根据ViewId hook对应的View // } // // @Override // public void hookView(Activity activity, View view, long delayTime) { // //hook对应的View // } // }); //onClick重复逻辑统一处理: 自定义具体实现 // ViewDoubleHelper.setICustomHookClick(new ICustomHookClick() { // @Override // public void hookResView(Activity activity, int viewResId, IOnClickListener iClickListener) { // // } // // @Override // public void hookView(Activity activity, View view, IOnClickListener iClickListener) { // // } // }); ``` # 三.历史版本: **V1.0.4:** 修复:版本兼容问题 **V1.0.3:** 修复bug: 每次pause返回, 都重复hookView **V1.0.2:** * ①.onClick重复逻辑统一处理使用IAddCustomHookClick处理, 添加自由扩展实现. * ②. 新增方法 ViewDoubleHelper.setIViewDoubleClick(IViewDoubleClick), ViewDoubleHelper.setICustomHookClick(ICustomHookClick); **V1.0.1:** 新增功能: onClick重复逻辑统一处理 **V1.0.0:** 新增功能: 无入侵解决按钮重复点击 ================================================ FILE: README2.0.6.md ================================================ # DoubleClick V2.0 的使用方法: 简书: https://www.jianshu.com/p/df0ef3866cc1 CSDN: https://blog.csdn.net/qq_33199629/article/details/101563232 **简单介绍:** ``` //项目根目录下,build.gradle allprojects { repositories { ... maven { url 'https://jitpack.io' } //添加 } } ``` ``` //app目录下build.gradle dependencies { implementation 'com.github.liys666666:DoubleClick:V2.0.6' //添加 } ``` ``` public class AppApplication extends Application{ @Override public void onCreate() { super.onCreate(); // ViewDoubleHelper.init(this); //默认时间：1秒 // ViewDoubleHelper.init(this, 500); //自定义点击间隔时间(单位：毫秒) ViewDoubleHelper.init(this, 1000, UnifiedDoubleClick.class); //自定义点击间隔时间(单位：毫秒) //单独设置, 不同的AnnotationClass可叠加(V2.0.5版本后可用) ViewDoubleHelper.addAnnotationClass(UnifiedDoubleClick2.class); } } ``` ``` public interface UnifiedDoubleClick{ //用户自定义接口 // >>>>>>>>>>>>>>>>>>>屏蔽DoubleClick的Activity>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> // @ACancelActivity(activitys = { // MainActivity.class, // }) // void cancelActivity(); // >>>>>>>>>>>>>>>>>>>单个view处理>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> @AAddDoubleClick(activity = MainActivity.class, addIds = {R.id.btn1, R.id.btn2}, times = {0, 2000}) //点击的间隔时间 void mainActivity(); // >>>>>>>>>>>>>>>>>插入自定义clickListener>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> @AClickListener(activity = MainActivity.class, lisenner = LoginClickListener.class, //自定义clickListener ids = {R.id.btn2}) void interceptMain(); } ``` ``` public class LoginClickListener extends BaseClickListener{ public static boolean isLogin = false; //模拟是否登陆 @Override public boolean isNext(View v) { //判断登录逻辑 (onClick前执行) return isLogin; //true继续执行onClick, false不再执行 } @Override public void after(View view) { //onClick后 执行 } } ``` **扩展---可调用方法** ``` //hook单个view(子View不会跟着变化) 例如: Recyclerview使用的话, itemView是不起作用的 ViewDoubleHelper.hookView(View view, long delayTime); hook单个view(所有子View会跟着一起变化) 例如: Recyclerview使用的话, itemView以及子控件全部有用 ViewDoubleHelper.hookChildViews(View view, long delayTime); //重新hook当前Activity ViewDoubleHelper.hookActivity(); //如果你有更好的实现方法, 也可以自己实现 ViewDoubleHelper.addIViewDoubleClick(IViewDoubleClick iHookView); ``` # 三.历史版本: **V2.0.6:** * 修复: * ViewDoubleHelper.hookChildViews() 不起作用 * ViewDoubleHelper.hookActivity()在onResume()前 调用不起作用. **V2.0.5:** * 优化: 问题描述:原来的注解只能在Application初始化时传一个类进去; * 问题1: 如果注解使用过多, 所有的注解都写在一个类里面, 不好管理. * 问题2: 在组件化架构中, 有个id无法在Application中获取. * 解决办法: 使用新增方法 ViewDoubleHelper.addAnnotationClass(annotationClass); 可设置多个 **V2.0.4:** * 修复: 动态加载View不起作用(包括自定义View, Fragment, RecyclerView中不起作用等等)。 **V2.0.2:** * 1. 修复兼容问题：注解android9.0不起作用. * 2. 手动重新hookActivity **V2.0.1:** * 1. 完全不需要在具体的Activity和Fragment加代码. * 2. 是否屏蔽hook、单个View处理, 自定义拦截器，全部使用接口注解处理. * 3. 单个View处理、自定义拦截器，兼容Fragment. [V1.0版本](https://github.com/liys666666/DoubleClick/blob/master/README1.0.4.md) * 如果框架中存在不足或者有什么建议, 欢迎指出, 我这边会尽快处理, 让框架更完善, 希望这个框架能帮助更多人, 如果觉得好用, 欢迎star. ================================================ FILE: app/.gitignore ================================================ /build ================================================ FILE: app/build.gradle ================================================ apply plugin: 'com.android.application' apply plugin: 'android-aspectjx' android { compileSdkVersion 28 defaultConfig { applicationId "com.liys.doubleclickdemo" minSdkVersion 19 targetSdkVersion 28 versionCode 6 versionName "3.0.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(include: ['*.jar'], dir: 'libs') implementation 'com.android.support:appcompat-v7:28.0.0' implementation 'com.android.support.constraint:constraint-layout:1.1.3' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' implementation project(':doubleclicklibrary') } ================================================ FILE: app/proguard-rules.pro ================================================ # Add project specific ProGuard rules here. # You can control the set of applied configuration files using the # proguardFiles setting in build.gradle. # # For more details, see # http://developer.android.com/guide/developing/tools/proguard.html # If your project uses WebView with JS, uncomment the following # and specify the fully qualified class name to the JavaScript interface # class: #-keepclassmembers class fqcn.of.javascript.interface.for.webview { # public *; #} # Uncomment this to preserve the line number information for # debugging stack traces. #-keepattributes SourceFile,LineNumberTable # If you keep the line number information, uncomment this to # hide the original source file name. #-renamesourcefileattribute SourceFile ================================================ FILE: app/src/androidTest/java/com/liys/doubleclickdemo/ExampleInstrumentedTest.java ================================================ package com.liys.doubleclickdemo; import android.content.Context; import android.support.test.InstrumentationRegistry; import android.support.test.runner.AndroidJUnit4; import org.junit.Test; import org.junit.runner.RunWith; import static org.junit.Assert.*; /** * Instrumented test, which will execute on an Android device. * * @see Testing documentation */ @RunWith(AndroidJUnit4.class) public class ExampleInstrumentedTest { @Test public void useAppContext() { // Context of the app under test.
