# PhotoPicker [](https://jitpack.io/#PengHaiZhuo/PhotoPicker) 图片选择器 #### 工程目录下gradle文件添加jitpack依赖： ``` allprojects { repositories { google() mavenCentral() gradlePluginPortal() maven { url "https://jitpack.io" } } } ``` #### 添加权限AndroidManifest.xml ``` <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.CAMERA" /> ``` #### sample使用了第三方库九宫格，添加依赖如下（本库也支持单选，请根据自己情况而定） ``` dependencies { //此处省略... //9宫格的图片选择 implementation 'com.jaeger.ninegridimageview:library:1.1.1' //本地库依赖 //implementation project(':photopicker') //远程依赖 implementation 'com.github.PengHaiZhuo:PhotoPicker:1.0.3' } ``` #### 使用 ``` /** * 当前选择的图片路径 */ private ArrayList<String> imagePathsList = new ArrayList<>(); /** * 允许上传照片最大数量 */ private static final int INT_MAXSIZE_IMG = 9; /** * 跳转到图片选择器 * @param position：预览图片需要传当前图片位置，配合imagePathsList使用 * @param isPick 是否是添加图片 */ private void toPickPhoto(int position,boolean isPick){ if (isPick) { PickImageIntent intent = new PickImageIntent(mContext); //设置为多选模式 intent.setSelectModel(SelectMode.MULTI); // 是否拍照 intent.setIsShowCamera(true); //设置最多选择照片数量 if (imagePathsList.size() > 0 && imagePathsList.size() < (INT_MAXSIZE_IMG + 1)) { // 最多选择照片数量 intent.setSelectedCount(INT_MAXSIZE_IMG + 1 - imagePathsList.size()); } else { intent.setSelectedCount(0); } /*// 已选中的照片地址，用于回显选中状态 intent.setSelectedPaths(imagePathsList);*/ startActivityForResult(intent, REQUEST_CAMERA_CODE); } else { //预览图片 PreViewImageIntent intent = new PreViewImageIntent(mContext); intent.setCurrentItem(position); intent.setPhotoPaths(imagePathsList); startActivityForResult(intent, REQUEST_PREVIEW_CODE); } } ``` #### 重写onActivityResult方法，获取选择的照片路径列表 ``` private static final int REQUEST_CAMERA_CODE = 10; private static final int REQUEST_PREVIEW_CODE = 20; @Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode==RESULT_OK){ switch (requestCode) { case REQUEST_CAMERA_CODE: if (data != null) { ArrayList<String> list = data.getStringArrayListExtra(ImagePickerConstract.EXTRA_RESULT); //todo 显示图片 } break; case REQUEST_PREVIEW_CODE: if (data != null) { ArrayList<String> ListExtra = data.getStringArrayListExtra(ImagePickerConstract.EXTRA_RESULT); if (imagePathsList != null) { imagePathsList.clear(); } imagePathsList.addAll(ListExtra); //todo 预览里可能删除了图片，所以需要更新显示的图片 } break; } } } ``` ## 部分截图 #### 图片选择  #### 预览  #### 9宫格
