1.在Project的`build.gradle`中添加仓库地址 48 | 49 | ```gradle 50 | allprojects { 51 | repositories { 52 | ... 53 | maven { url "https://jitpack.io" } 54 | } 55 | } 56 | ``` 57 | 58 | #### 2.在Module目录下的`build.gradle`中添加依赖 59 | 60 | [![](https://jitpack.io/v/ITxiaoguang/SelectTextHelper.svg)](https://jitpack.io/#ITxiaoguang/SelectTextHelper) 61 | 62 | 63 | ```gradle 64 | dependencies { 65 | implementation 'com.github.ITxiaoguang:SelectTextHelper:1.1.0' 66 | } 67 | ``` 68 | 69 | ## 传送门 70 | 71 | * [仿照的例子](https://www.dazhuanlan.com/t0915/topics/1440960) 72 | * [放大镜](https://developer.android.google.cn/guide/topics/text/magnifier) 73 | * [TextView](https://developer.android.google.cn/reference/android/widget/TextView) 74 | * [富文本](https://github.com/zzhoujay/RichText) 75 | 76 | 77 | ### 主要实现 78 | 79 | 通过 [仿照的例子](https://www.dazhuanlan.com/t0915/topics/1440960) 并改进弹窗坐标位置、加对ImageSpan支持、大小加上`EventBus`实现 80 | 81 | ### 简单用例 82 | 83 | #### 1.导入代码 84 | 85 | 把该项目里的`selecttext Module`放入你的项目里面 或者 按照`Gradle`添加的步骤导入依赖。 86 | 87 | #### 2.给你的`TextView`创建`Helper`和加监听 88 | 89 | ```kotlin 90 | val mSelectableTextHelper = SelectTextHelper.Builder(textView) // 放你的textView到这里！！ 91 | .setCursorHandleColor(ContextCompat.getColor(mContext, R.color.colorAccent)) // 游标颜色 92 | .setCursorHandleSizeInDp(22f) // 游标大小 单位dp 93 | .setSelectedColor(ContextCompat.getColor(mContext, R.color.colorAccentTransparent)) // 选中文本的颜色 94 | .setSelectAll(true) // 初次选中是否全选 default true 95 | .setScrollShow(true) // 滚动时是否继续显示 default true 96 | .setSelectedAllNoPop(true) // 已经全选无弹窗，设置了监听会回调 onSelectAllShowCustomPop 方法 97 | .setMagnifierShow(true) // 放大镜 default true 98 | .setSelectTextLength(2)// 首次选中文本的长度 default 2 99 | .setPopDelay(100)// 弹窗延迟时间 default 100毫秒 100 | .setPopAnimationStyle(R.style.Base_Animation_AppCompat_Dialog)// 弹窗动画 default 无动画 101 | .addItem(0/*item的图标*/,"复制"/*item的描述*/, {Log.i("SelectTextHelper","复制")/*item的回调*/}// 操作弹窗的每个item 102 | .setPopSpanCount(5) // 设置操作弹窗每行个数 default 5 103 | .setPopStyle( 104 | R.drawable.shape_color_4c4c4c_radius_8 /*操作弹窗背*/, 105 | R.drawable.ic_arrow /*箭头图片*/ 106 | ) // 设置操作弹窗背景色、箭头图片 107 | .build() 108 | 109 | mSelectableTextHelper!!.setSelectListener(object : OnSelectListener { 110 | /** 111 | * 点击回调 112 | */ 113 | override fun onClick(v: View?, originalContent: CharSequence?) { 114 | // 拿原始文本方式 115 | // clickTextView(msgBean.content!!) // 推荐 116 | // clickTextView(originalContent!!) // 不推荐 富文本可能被修改值 导致gif动不了 117 | } 118 | 119 | /** 120 | * 长按回调 121 | */ 122 | override fun onLongClick(v: View?) { 123 | } 124 | 125 | /** 126 | * 选中文本回调 127 | */ 128 | override fun onTextSelected(content: CharSequence?) { 129 | } 130 | 131 | /** 132 | * 弹窗关闭回调 133 | */ 134 | override fun onDismiss() {} 135 | 136 | /** 137 | * 点击TextView里的url回调 138 | * 139 | * 已被下面重写 140 | * textView.setMovementMethod(new LinkMovementMethodInterceptor()); 141 | */ 142 | override fun onClickUrl(url: String?) { 143 | } 144 | 145 | /** 146 | * 全选显示自定义弹窗回调 147 | */ 148 | override fun onSelectAllShowCustomPop() { 149 | } 150 | 151 | /** 152 | * 重置回调 153 | */ 154 | override fun onReset() { 155 | // SelectTextEventBus.instance.dispatch(SelectTextEvent("dismissOperatePop")) 156 | } 157 | 158 | /** 159 | * 解除自定义弹窗回调 160 | */ 161 | override fun onDismissCustomPop() { 162 | // SelectTextEventBus.instance.dispatch(SelectTextEvent("dismissOperatePop")) 163 | } 164 | 165 | /** 166 | * 是否正在滚动回调 167 | */ 168 | override fun onScrolling() { 169 | // removeShowSelectView() 170 | } 171 | }) 172 | 173 | ``` 174 | 175 | #### 3.demo中提供了查看文本内容的`SelectTextDialog`和 消息列表自由复制`MainActivity` 176 | 177 | 查看文本内容方法： 178 | 179 | * 该方法比较简单，将`textView`参照步骤2放入`SelectTextHelper`中，在`dismiss`调用`SelectTextHelper`的`reset()`即可。 180 | 181 | ```kotlin 182 | override fun dismiss() { 183 | mSelectableTextHelper.reset() 184 | super.dismiss() 185 | } 186 | ``` 187 | 188 | 高仿微信聊天消息列表自由复制方法： 189 | 190 | * `recycleView` + `adapter` + 多布局的使用在这里不阐述，请看本项目demo。 191 | 192 | * 为`adapter`里text类型`ViewHolder`中的`textView`参照步骤2放入`SelectTextHelper`中，注册`SelectTextEventBus`。 193 | 194 | * `SelectTextEventBus`类特别说明、原理： 195 | `SelectTextEventBus`在`EventBus`基础上加功能。在`register`时记录下类和方法，方便在`Activity/Fragment Destroy`时`unregister`所有`SelectTextEventBus`的`EventBus`。 196 | 197 | * text类型`ViewHolder` 添加`EventBus`监听 198 | 199 | ```kotlin 200 | /** 201 | * 自定义SelectTextEvent 隐藏 光标 202 | */ 203 | @Subscribe(threadMode = ThreadMode.MAIN) 204 | fun handleSelector(event: SelectTextEvent) { 205 | if (null == mSelectableTextHelper) { 206 | return 207 | } 208 | val type = event.type 209 | if (TextUtils.isEmpty(type)) { 210 | return 211 | } 212 | when (type) { 213 | "dismissAllPop" -> mSelectableTextHelper!!.reset() 214 | "dismissAllPopDelayed" -> postReset(Companion.RESET_DELAY) 215 | } 216 | } 217 | ``` 218 | 219 | * 重写`adapter`里的`onViewRecycled`方法，该方法在回收`View`时调用 220 | 221 | ```kotlin 222 | override fun onViewRecycled(holder: RecyclerView.ViewHolder) { 223 | super.onViewRecycled(holder) 224 | if (holder is ViewHolderText) { 225 | // 注销 226 | SelectTextEventBus.instance.unregister(holder) 227 | } 228 | } 229 | ``` 230 | 231 | - 对ImageSpan表情支持(支持动态表情！！)（https://github.com/ITxiaoguang/SelectTextHelper/issues/4 ） 232 | 233 | ```kotlin 234 | val emojiMap: MutableMap = HashMap() 235 | emojiMap["\\[笑脸\\]"] = R.drawable.emoji_00 236 | emojiMap["\\[瘪嘴\\]"] = R.drawable.emoji_01 237 | emojiMap["\\[色\\]"] = R.drawable.emoji_02 238 | emojiMap["\\[瞪大眼\\]"] = R.drawable.emoji_03 239 | emojiMap["\\[酷\\]"] = R.drawable.emoji_04 240 | emojiMap["\\[Android\\]"] = R.mipmap.ic_launcher_round 241 | emojiMap["\\[好的\\]"] = R.drawable.emoji_gif 242 | emojiMap["\\[羊驼\\]"] = R.drawable.emoji_gif2 243 | ```` 244 | 245 | - 富文本支持 [富文本用法点这里](https://github.com/zzhoujay/RichText) 246 | 247 | ```kotlin 248 | // todo 方法一：富文本 需要转行成富文本形式 249 | RichText.initCacheDir(holder.textView.context.applicationContext) // 项目里初始化一次即可 250 | RichText.from(msgBean.content) 251 | .autoFix(false) // 是否自动修复宽高，默认true 252 | .autoPlay(true) // gif自动播放 253 | .singleLoad(false) // RecyclerView里设为false 若同时启动了多个RichText，会并发解析，类似于AsyncTask的executeOnExecutor 254 | .done { // 在成功回调处理 255 | // 演示消息列表选择文本 256 | holder.selectText(msgBean) 257 | } 258 | .into(holder.textView) 259 | 260 | // todo 方法二：普通文本 261 | holder.textView.text = msgBean.content 262 | // 演示消息列表选择文本 263 | holder.selectText(msgBean) 264 | ``` 265 |
