8 | #### （一）初始化
9 | ```
10 | helpr = PictureUseHelpr.init(this).
11 | setMaxNum(9).
12 | origin(mSelect).
13 | bindRecyclerView(rvImages, R.id.iv_thum);
14 | ```
15 | #### （二）选择图片
16 | ```
17 | helpr.pickImage(REQUEST_IMAGE);
18 |
19 | @Override
20 | protected void onActivityResult(int requestCode, int resultCode, Intent data) {

32 |
33 | #### （三）显示大图
34 | ```
35 | helpr.show(position);
36 | ```
37 |
38 |
39 | # 一、前言
40 |
41 | 应工作上的要求，需要有一个类似于微信朋友圈发动态上传图片的功能，想起曾经已经做过了，但奈何不忍看自己以前写的代码的惨状，觉得重新封装一个使用方便，易于维护的类似功能的类，自己之后用起来也顺手，当然也方便一下大家，这样可以加快我们工作的效率，让我们有更多的时间学习（划水）。
42 |
43 | 
44 |
45 | 功能上的话，目前有添加图片、查看大图、删除图片
46 |
47 | # 二、效果图
48 | 先贴一下效果图吧
49 |
50 | 
51 |
52 | # 三、实现功能
53 | 库有用到butterknife和显示图片的glide
54 | 适配器用的rvadapter，加一个删除功能的气泡弹窗
55 | 引入一下相关依赖：
56 | ```
57 | api 'com.jakewharton:butterknife:10.2.1'
58 | annotationProcessor 'com.jakewharton:butterknife-compiler:10.2.1'
59 |
60 | implementation 'com.github.bumptech.glide:glide:4.5.0'
61 | annotationProcessor 'com.github.bumptech.glide:compiler:4.5.0'
62 |
63 | //气泡弹窗
64 | implementation 'me.kareluo.ui:popmenu:1.1.0'
65 | implementation 'com.zhy:base-rvadapter:3.0.3'
66 | ```
67 | ####（一）布局文件
68 | 主页面上的话，只有一个RecyclerView，他的LayoutManager设为GridLayoutManager，一行为3个
69 | ```
70 |
71 |
77 |
78 |
83 |
84 |
85 | ```
86 |
87 | 子布局的话，有两个ImageView，一个是普通的图片，另外一个固定为那个添加的按钮
88 | ```
89 |
90 |
97 |
98 |
104 |
105 |
112 |
113 |
114 |
115 | ```
116 |
117 | #### （二）Activity代码
118 |
119 | 先来看一下如何在我们的页面里使用我已经写好的这个adapter
120 |
121 | 首先初始化一下控件和adapter，给adapter设置一个点击添加图片的监听
122 | ```
123 | private void initView() {
124 | rvImages.setLayoutManager(new GridLayoutManager(this, 3));
125 | adapter = new NineGridAdapter(MainActivity.this, mSelectList, rvImages);
126 | adapter.setMaxSize(maxNum);
127 | rvImages.setAdapter(adapter);
128 | adapter.setOnAddPicturesListener(new OnAddPicturesListener() {
129 | @Override
130 | public void onAdd() {
131 | pickImage();
132 | }
133 | });
134 | }
135 | ```
136 |
137 | 选择图片页面的启动
138 | ```
139 | private void pickImage() {
140 | MultiImageSelector selector = MultiImageSelector.create(context);
141 | selector.showCamera(true);
142 | selector.count(maxNum);
143 | selector.multi();
144 | selector.origin(mSelectList);
145 | selector.start(instans, REQUEST_IMAGE);
146 | }
147 | ```
148 |
149 | 拿到选择图片页面的返回数据，添加至List中
150 | ```
151 | @Override
152 | protected void onActivityResult(int requestCode, int resultCode, Intent data) {
153 | super.onActivityResult(requestCode, resultCode, data);
154 | if (requestCode == REQUEST_IMAGE) {
155 | if (resultCode == RESULT_OK) {
156 | List select = data.getStringArrayListExtra(MultiImageSelector.EXTRA_RESULT);
157 | mSelectList.clear();
158 | mSelectList.addAll(select);
159 | adapter.notifyDataSetChanged();
160 | }
161 | }
162 | }
163 | ```
164 |
165 | #### （三）适配器代码
166 |
167 | 首先在构造函数中，往list里添加一个空串，为添加按钮占位。之后初始化一下删除气泡按钮跟大图显示的控件
168 | ```
169 | public NineGridAdapter(Context context, List selectPath, RecyclerView rvImages) {
170 | super(context, R.layout.item_img, selectPath);
171 | this.context = context;
172 |
173 | selectPath.add("");
174 | initDeleteMenu();
175 | initTransfer(rvImages);
176 | }
177 | ```
178 | 两个控件初始化的代码
179 | ```
180 | /**
181 | * 初始化大图查看控件
182 | */
183 | private void initTransfer(RecyclerView rvImages) {
184 | transferee = Transferee.getDefault(context);
185 | config = TransferConfig.build()
186 | .setSourceImageList(getDatas())
187 | .setProgressIndicator(new ProgressBarIndicator())
188 | .setIndexIndicator(new NumberIndexIndicator())
189 | .setImageLoader(GlideImageLoader.with(context.getApplicationContext()))
190 | .setJustLoadHitImage(true)
191 | .bindRecyclerView(rvImages, R.id.iv_thum);
192 | }
193 |
194 | /**
195 | * 初始化图片删除小弹窗
196 | */
197 | private void initDeleteMenu() {
198 | menuView = new PopupMenuView(context, R.menu.menu_pop, new MenuBuilder(context));
199 | menuView.setSites(PopupView.SITE_TOP);
200 | menuView.setOnMenuClickListener(new OptionMenuView.OnOptionMenuClickListener() {
201 | @Override
202 | public boolean onOptionMenuClick(int position, OptionMenu menu) {
203 | getDatas().remove(deletePosition);
204 | if (!getDatas().get(getDatas().size() - 1).equals("")) {
205 | //列表最后一张不是添加按钮时，加入添加按钮
206 | getDatas().add("");
207 | }
208 | notifyDataSetChanged();
209 | return true;
210 | }
211 | });
212 | }
213 | ```
214 | 在item填充的函数中完成图片的显示，点击和长按的监听
215 | ```
216 | @Override
217 | protected void convert(ViewHolder viewHolder, String item, final int position) {
218 | ImageView ivThum = viewHolder.getView(R.id.iv_thum);
219 | ImageView ivAdd = viewHolder.getView(R.id.iv_add);
220 | if (item.equals("")) {
221 | //item为添加按钮
222 | ivThum.setVisibility(View.GONE);
223 | ivAdd.setVisibility(View.VISIBLE);
224 | } else {
225 | //item为普通图片
226 | ivThum.setVisibility(View.VISIBLE);
227 | ivAdd.setVisibility(View.GONE);
228 | }
229 | Glide.with(mContext).load(item).into(ivThum);
230 | ivThum.setOnClickListener(new PicturesClickListener(position));
231 | ivAdd.setOnClickListener(new PicturesClickListener(position));
232 |
233 | ivThum.setOnLongClickListener(new View.OnLongClickListener() {
234 | @Override
235 | public boolean onLongClick(View view) {
236 | deletePosition = position;
237 | //最上面的三个删除按钮是往下的 其他的都是往上的
238 | if (position < 3) {
239 | menuView.setSites(PopupView.SITE_BOTTOM);
240 | } else {
241 | menuView.setSites(PopupView.SITE_TOP);
242 | }
243 | menuView.show(view);
244 | return false;
245 | }
246 | });
247 | }
248 | ```
249 | 点击事件代码
250 | ```
251 | private class PicturesClickListener implements View.OnClickListener {
252 |
253 | int position;
254 |
255 | public PicturesClickListener(int position) {
256 | this.position = position;
257 | }
258 |
259 | @Override
260 | public void onClick(View view) {
261 | switch (view.getId()) {
262 | case R.id.iv_thum:
263 | //点击图片
264 | config.setNowThumbnailIndex(position);
265 | config.setSourceImageList(getDatas());
266 | transferee.apply(config).show();
267 | break;
268 | case R.id.iv_add:
269 | //点击添加按钮
270 | if (listener != null)
271 | listener.onAdd();
272 | break;
273 | }
274 | }
275 | }
276 | ```
277 | # 四、关于老v7项目的问题
278 | 前段时间也是刚把自己的项目从v7手动改为androidx的，忙活了半天，后来发现android studio有一键将v7项目改为新的androidx的项目，算是给自己记个笔记
