# 实现拍照功能 步骤 #

1、引入两个第三方依赖包

implementation 'io.github.lucksiege:pictureselector:v2.7.2'
    implementation 'com.github.bumptech.glide:glide:4.12.0'

2、添加文件读写权限和相机拍照权限

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
     <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
     <uses-permission android:name="android.permission.CAMERA" />
    
     android:requestLegacyExternalStorage="true"

3、拍照功能，调用第三方框架，Glide图片封装工具类

## 拍照 ##

findViewById(R.id.button).setOnClickListener(new View.OnClickListener() { 
                @Override
                public void onClick(View v) { 
    //                拍照功能
                    PictureSelector.create(MainActivity.this)
                            .openCamera(PictureMimeType.ofImage())
                            .imageEngine(GlideEngine.createGlideEngine())
                            .forResult(new OnResultCallbackListener<LocalMedia>() { 
                                @Override
                                public void onResult(List<LocalMedia> result) { 
                                    // onResult Callback
    
                                    for (LocalMedia localMedia : result){ 
                                        Log.i("MainActivity",localMedia.getPath());
                                    }
                                    //todo 显示图片
                                    //网络请求xUtils https 上传  mock  后台接收
                                    //读取图片  io流程   流数据转成图片
                                    Glide.with(MainActivity.this)
                                            .load(Uri.fromFile(new File(result.get(0).getRealPath())))
                                            .into(imageView);
                                }
                                @Override
                                public void onCancel() { 
                                    // onCancel Callback
                                }
                            });
                }
            });

## 选择相片 ##

findViewById(R.id.button2).setOnClickListener(new View.OnClickListener() { 
                @Override
                public void onClick(View v) { 
    //                选择照片功能
                    PictureSelector.create(MainActivity.this)
                            .openGallery(PictureMimeType.ofImage())
                            .imageEngine(GlideEngine.createGlideEngine())
                            .forResult(new OnResultCallbackListener<LocalMedia>() { 
                                @Override
                                public void onResult(List<LocalMedia> result) { 
                                    // onResult Callback
    
                                    for (LocalMedia localMedia : result){ 
                                        Log.i("MainActivity",localMedia.getPath());
                                    }
                                    //todo 显示图片
                                    //网络请求xUtils https 上传  mock  后台接收
                                    //读取图片  io流程   流数据转成图片
                                    Glide.with(MainActivity.this)
                                            .load(Uri.fromFile(new File(result.get(0).getRealPath())))
                                            .into(imageView);
                                }
                                @Override
                                public void onCancel() { 
                                    // onCancel Callback
                                }
                            });
                }
            });

4、如果报错，uses-sdk版本太低，进行修改
