  1 | # AvoidOnResultHelper
  2 | 避免 onActivityResult 和 onRequestPermissionsResult 烦恼requestCode的问题，帮助快速开发~~
  3 | 
  4 | ## 原理讲解
  5 | 
  6 | [原理讲解，点我！](https://blog.ruoyun.vip/post/%E5%A4%A7%E8%83%B8%E5%BC%9F-requestcode%E8%BF%98%E5%9C%A8%E5%9B%B0%E6%89%B0%E4%BD%A0%E5%98%9B/)
  7 | 
  8 | ## 使用方法
  9 | 在子项目中的 build.gradle 文件中添加
 10 | 
 11 | ```java
 12 | dependencies {
 13 |     implementation 'vip.ruoyun.helper:avoid-onresult-helper:1.0.4'
 14 | }
 15 | ```
 16 | 
 17 | ## 开启 Activity
 18 | 
 19 | ```java
 20 | Intent intent = new Intent();
 21 | AvoidOnResultHelper.startActivityForResult(this, intent, new AvoidOnResultHelper.ActivityCallback() {
 22 |     @Override
 23 |     public void onActivityResult(int resultCode, Intent data) {
 24 |         //接收数据
 25 |         //Log.d("MainActivity", "resultCode:" + resultCode);
 26 |         //Log.d("MainActivity", "Intent data:" + data.getStringExtra("text"));
 27 |     }
 28 | });
 29 | ```
 30 | 
 31 | ## 关闭 Activity，并回传值
 32 | 
 33 | 在新的Activity中，通过下面的方法来快速关闭界面并传回值。
 34 | ```java
 35 | AvoidOnResultHelper.finishWithResult(activity, Activity.RESULT_OK, intent);
 36 | AvoidOnResultHelper.finishWithResult(activity, Activity.RESULT_OK, bundle);
 37 | //相当于
 38 | //Intent intent = new Intent();
 39 | //intent.putExtra("text", "返回数据");
 40 | //setResult(Activity.RESULT_OK, intent);
 41 | //finish();
 42 | ```
 43 | 
 44 | ## 请求权限
 45 | 
 46 | ```java
 47 | String[] permissions = {};
 48 | AvoidOnResultHelper.requestPermissions(this, permissions, new AvoidOnResultHelper.PermissionsCallBack() {
 49 |     @Override
 50 |     public void onRequestPermissionsResult(@NonNull String[] permissions, @NonNull int[] grantResults) {
 51 | 
 52 |     }
 53 | });
 54 | ```
 55 | 
 56 | ## 设置 RequestCodeRange 范围
 57 | 如果在使用的过程中,发现 RequestCode 和原有的值发生冲突,那么可以通过下面的方法,进行设置
 58 | 默认值为:
 59 | 
 60 | - start:65000
 61 | - end:65535
 62 | 
 63 | ```java
 64 | AvoidOnResultHelper.setRequestCodeRange(65000, 65535);
 65 | ```
 66 | 
 67 | ## 生命周期
 68 | 监听当前 activity 的生命周期.
 69 | ```java
 70 | public interface LifecycleListener {
 71 | 
 72 |     void onStart();//开始
 73 | 
 74 |     void onStop();//结束
 75 | 
 76 |     void onDestroy();//销毁
 77 | }
 78 | ```
 79 | LifecycleListenerWrapper 是此接口的空实现.
 80 | 
 81 | 使用
 82 | ```java
 83 | //添加监听事件
 84 | LifecycleListener lifecycleListener = new LifecycleListener.LifecycleListenerWrapper() {
 85 |     @Override
 86 |     public void onStart() {
 87 |     }
 88 | };
 89 | //添加监听事件
 90 | AvoidOnResultHelper.addLifecycleListener(this, lifecycleListener);
 91 | 
 92 | //粘性通知,当第一次添加的时候,就执行相应的回调方法
 93 | AvoidOnResultHelper.addLifecycleListener(this, lifecycleListener, true);
 94 | ```
 95 | 
 96 | 可选操作
 97 | ```java
 98 | //移除监听事件,默认可以不用移除lifecycleListener,除非在当前界面存在时候,想要不让某些类监听,那么可以手动进行移除(removeLifecycleListener)
 99 | AvoidOnResultHelper.removeLifecycleListener(this, lifecycleListener);
100 | ```
101 | 
102 | ## 原理
103 | 
104 | ### 问题
105 | 
106 | 当在一个界面中打开另一个界面的时候，如果想要新界面传回值，那么就需要执行下面的方法
107 | ```java
108 | //定义 requestCode 
109 | startActivityForResult(Intent intent, int requestCode);
110 | ```
111 | 然后在要接受数据的界面添加如下方法
112 | ```java
113 | @Override
114 | public void onActivityResult(int requestCode, int resultCode, Intent data) {
115 |     super.onActivityResult(requestCode, resultCode, data);
116 |     //判断 requestCode
117 | }
118 | ```
119 | 
120 | 比如打开相册，要写如下的代码。
121 | ```java
122 | private final static int REQUEST_CODE = 100;
123 | 
124 | private void choosePhoto(){
125 |     //省略权限检测和申请
126 |     ...
127 |     Intent intentToPickPic = new Intent(Intent.ACTION_PICK, null);
128 |     // 如果限制上传到服务器的图片类型时可以直接写如："image/jpeg 、 image/png等的类型" 所有类型则写 "image/*"
129 |     intentToPickPic.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/jpeg");
130 |     startActivityForResult(intentToPickPic, REQUEST_CODE);
131 | }
132 | 
133 | //当拍摄照片完成时会回调到onActivityResult 在这里处理照片的裁剪
134 | @Override
135 | public void onActivityResult(int requestCode, int resultCode, Intent data) {
136 |     if (resultCode == RESULT_OK) {
137 |         switch (requestCode) {
138 |             case REQUEST_CODE: {
139 |                //处理图片逻辑
140 |                ...
141 |                break;
142 |             }
143 |         }
144 |     }
145 |     super.onActivityResult(requestCode, resultCode, data);
146 | }
147 | ```
148 | 
149 | 所以，我们想要做这些操作的时候，要写至少 18 行代码 和定义一个 code 码。如果快速开的话，这些操作还挺烦的。
150 | 那么我们应该怎么来进行简单呢？
151 | 
152 | ### 解决方法
153 | 
154 | 当阅读 glide 源码的时候，发现它可以监听声明周期，让图片随着界面的声明周期进行下载和展示，那么它是如何来解决这个问题的呢？
155 | 
156 | 它是在 调用 with 的时候，传入的上下文，来监听界面的事件。
157 | ```java
158 | Glide.with(this).load("http://goo.gl/gEgYUd").into(imageView);
159 | ```
160 | 
161 | ### 分析 FragmentActivity 源码
162 | ```java
163 | final FragmentManagerImpl mFragments = new FragmentManagerImpl();
164 | 
165 | protected void onCreate(@Nullable Bundle savedInstanceState) {
166 |     this.mFragments.attachHost((Fragment)null);
167 |     super.onCreate(savedInstanceState);
168 |     ...//省略不必要的代码
169 |     
170 |     this.mFragments.dispatchCreate();
171 | }
172 | 
173 | protected void onStart() {
174 |     super.onStart();
175 |     ...//省略不必要的代码
176 | 
177 |     this.mFragments.noteStateNotSaved();
178 |     this.mFragments.execPendingActions();
179 |     this.mFragments.dispatchStart();
180 | }
181 | 
182 | protected void onStop() {
183 |     super.onStop();
184 |     ...//省略不必要的代码
185 |     this.mFragments.dispatchStop();
186 | }
187 | 
188 | 
189 | protected void onPause() {
190 |     super.onPause();
191 |     ...//省略不必要的代码
192 |     
193 |     this.mFragments.dispatchPause();
194 | }
195 | 
196 | protected void onDestroy() {
197 |     super.onDestroy();
198 |     ...//省略不必要的代码
199 | 
200 |     this.mFragments.dispatchDestroy();
201 | }
202 |

230 | ```
231 | 
232 | 我们在来看  FragmentManagerImpl 的源码，就知道 FragmentActivity 的声明周期方法在执行的时候，都会执行包含的 fragment 的声明周期方法。
233 | ```java
234 | public void dispatchCreate() {
235 |     mStateSaved = false;
236 |     moveToState(Fragment.CREATED, false);
237 | }
238 | 
239 | public void dispatchActivityCreated() {
240 |     mStateSaved = false;
241 |     moveToState(Fragment.ACTIVITY_CREATED, false);
242 | }
243 | 
244 | public void dispatchStart() {
245 |     mStateSaved = false;
246 |     moveToState(Fragment.STARTED, false);
247 | }
248 | 
249 | void moveToState(int newState, boolean always) {
250 |     moveToState(newState, 0, 0, always);
251 | }
252 | 
253 | void moveToState(int newState, int transit, int transitStyle, boolean always) {
254 |     ...//省略不必要的代码
255 |     if (mActive != null) {
256 |         boolean loadersRunning = false;
257 |         for (int i=0; i<mActive.size(); i++) {
258 |             Fragment f = mActive.get(i);
259 |             if (f != null) {
260 |                 moveToState(f, newState, transit, transitStyle, false);// 执行声明周期方法
261 |                 ...//省略不必要的代码
262 |             }
263 |         }
264 |         ...//省略不必要的代码
265 |     }
266 | }
267 | 
268 | void moveToState(Fragment f, int newState, int transit, int transitionStyle,
269 |         boolean keepActive) {
270 |         ...//省略不必要的代码
271 |         switch (f.mState) {
272 |             case Fragment.INITIALIZING:
273 |                 ...//省略不必要的代码
274 |                 f.onAttach(mActivity);
275 |                 ...//省略不必要的代码
276 |                 if (f.mFromLayout) {
277 |                     ...//省略不必要的代码
278 |                     if (f.mView != null) {
279 |                         ...//省略不必要的代码
280 |                         f.onViewCreated(f.mView, f.mSavedFragmentState);
281 |                     } else {
282 |                         f.mInnerView = null;
283 |                     }
284 |                 }

286 |                     ...//省略不必要的代码
287 |                     f.onViewCreated(f.mView, f.mSavedFragmentState);
288 |                     ...//省略不必要的代码
289 |             case Fragment.ACTIVITY_CREATED:
290 |             case Fragment.STOPPED:
291 |                 ...//省略不必要的代码
292 |                 f.performStart();
293 |             case Fragment.STARTED:
294 |                 ...//省略不必要的代码
295 |                 f.performResume();
296 |         }
297 |     } else if (f.mState > newState) {
298 |         switch (f.mState) {
299 |             case Fragment.RESUMED:
300 |                 ...//省略不必要的代码
301 |                     f.performPause();
302 |             case Fragment.STARTED:
303 |                     f.performStop();
304 |             case Fragment.STOPPED:
305 |                     f.performReallyStop();
306 |             case Fragment.ACTIVITY_CREATED:
307 |                     f.performDestroyView();
308 |             case Fragment.CREATED:
309 |                 ...//省略不必要的代码
310 |         }
311 |     }
312 |     f.mState = newState;
313 | }
314 | ```
315 | 
316 | 这里，我们就可以 创建一个 没有界面的 fragment 添加到 activity 中，就可以完美监听界面的声明周期 和回调方法。到此原理讲解结束。
317 |

 86 |       granted to You under this License for that Work shall terminate
 87 |       as of the date such litigation is filed.
 88 | 
 89 |    4. Redistribution. You may reproduce and distribute copies of the
 90 |       Work or Derivative Works thereof in any medium, with or without
 91 |       modifications, and in Source or Object form, provided that You
 92 |       meet the following conditions:
 93 | 
 94 |       (a) You must give any other recipients of the Work or
 95 |           Derivative Works a copy of this License; and
 96 | 
 97 |       (b) You must cause any modified files to carry prominent notices
 98 |           stating that You changed the files; and
 99 | 
100 |       (c) You must retain, in the Source form of any Derivative Works
101 |           that You distribute, all copyright, patent, trademark, and
102 |           attribution notices from the Source form of the Work,
103 |           excluding those notices that do not pertain to any part of
104 |           the Derivative Works; and
105 | 
106 |       (d) If the Work includes a "NOTICE" text file as part of its
107 |           distribution, then any Derivative Works that You distribute must
108 |           include a readable copy of the attribution notices contained
109 |           within such NOTICE file, excluding those notices that do not
110 |           pertain to any part of the Derivative Works, in at least one
111 |           of the following places: within a NOTICE text file distributed
112 |           as part of the Derivative Works; within the Source form or
113 |           documentation, if provided along with the Derivative Works; or,
114 |           within a display generated by the Derivative Works, if and
115 |           wherever such third-party notices normally appear. The contents
116 |           of the NOTICE file are for informational purposes only and
117 |           do not modify the License. You may add Your own attribution
118 |           notices within Derivative Works that You distribute, alongside
119 |           or as an addendum to the NOTICE text from the Work, provided
120 |           that such additional attribution notices cannot be construed
121 |           as modifying the License.
122 | 
123 |       You may add Your own copyright statement to Your modifications and
124 |       may provide additional or different license terms and conditions
125 |       for use, reproduction, or distribution of Your modifications, or
126 |       for any such Derivative Works as a whole, provided Your use,
127 |       reproduction, and distribution of the Work otherwise complies with
128 |       the conditions stated in this License.
129 | 
130 |    5. Submission of Contributions. Unless You explicitly state otherwise,
131 |       any Contribution intentionally submitted for inclusion in the Work
132 |       by You to the Licensor shall be under the terms and conditions of
133 |       this License, without any additional terms or conditions.
134 |       Notwithstanding the above, nothing herein shall supersede or modify
135 |       the terms of any separate license agreement you may have executed
136 |       with Licensor regarding such Contributions.
137 | 
138 |    6. Trademarks. This License does not grant permission to use the trade
139 |       names, trademarks, service marks, or product names of the Licensor,
140 |       except as required for reasonable and customary use in describing the
141 |       origin of the Work and reproducing the content of the NOTICE file.
142 | 
143 |    7. Disclaimer of Warranty. Unless required by applicable law or
144 |       agreed to in writing, Licensor provides the Work (and each
145 |       Contributor provides its Contributions) on an "AS IS" BASIS,
146 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 |       implied, including, without limitation, any warranties or conditions
148 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 |       PARTICULAR PURPOSE. You are solely responsible for determining the
150 |       appropriateness of using or redistributing the Work and assume any
151 |       risks associated with Your exercise of permissions under this License.
152 | 
153 |    8. Limitation of Liability. In no event and under no legal theory,
154 |       whether in tort (including negligence), contract, or otherwise,
155 |       unless required by applicable law (such as deliberate and grossly
156 |       negligent acts) or agreed to in writing, shall any Contributor be
157 |       liable to You for damages, including any direct, indirect, special,
158 |       incidental, or consequential damages of any character arising as a
159 |       result of this License or out of the use or inability to use the
160 |       Work (including but not limited to damages for loss of goodwill,
161 |       work stoppage, computer failure or malfunction, or any and all
162 |       other commercial damages or losses), even if such Contributor
163 |       has been advised of the possibility of such damages.
164 | 
165 |    9. Accepting Warranty or Additional Liability. While redistributing
166 |       the Work or Derivative Works thereof, You may choose to offer,
167 |       and charge a fee for, acceptance of support, warranty, indemnity,
168 |       or other liability obligations and/or rights consistent with this
169 |       License. However, in accepting such obligations, You may act only
170 |       on Your own behalf and on Your sole responsibility, not on behalf
171 |       of any other Contributor, and only if You agree to indemnify,
172 |       defend, and hold each Contributor harmless for any liability
173 |       incurred by, or claims asserted against, such Contributor by reason
174 |       of your accepting any such warranty or additional liability.
175 | 
176 |    END OF TERMS AND CONDITIONS
177 | 
178 |    APPENDIX: How to apply the Apache License to your work.
179 | 
180 |       To apply the Apache License to your work, attach the following
181 |       boilerplate notice, with the fields enclosed by brackets "[]"
