一、选择相册（FilePicker）

1、导入依赖

implementation 'cn.imlibo:FilePicker:v0.0.5_alpha'

2、使用方法

①选择指定后缀文件

FilePicker
                .from(this)
                .chooseForMimeType()//选择指定后缀文件
                .setMaxCount(10)
                .setFileTypes("png", "doc","apk", "mp3", "gif", "txt", "mp4", "zip")
                .requestCode(REQUEST_CODE_CHOOSE)//确认码
                .start();

②在图片选择器中选择图片或视频

FilePicker
                .from(this)
                .chooseMedia()//图片选择器
                .enabledCapture(true)
                .setTheme(R.style.FilePicker_Dracula)
                .requestCode(REQUEST_CODE_CHOOSE)
                .start();

③接受返回的文件

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode != RESULT_OK) {
            return;
        }
        if (requestCode == REQUEST_CODE_CHOOSE) {
            ArrayList<EssFile> essFileList = data.getParcelableArrayListExtra(Const.EXTRA_RESULT_SELECTION);
            StringBuilder builder = new StringBuilder();
            for (EssFile file :
                    essFileList) {
                builder.append(file.getMimeType()).append(" | ").append(file.getName()).append("\n\n");
            }
            textView.setText(builder.toString());//显示选取结果
           //setViewText(builder.toString(), pathName);通常上传的时候需要文件路径，新写一个方法保存文件路径
        }
    }

3、Git地址

二、拍照（TakePhoto）

①、添加依赖

 repositories {
       //glide
        mavenCentral()
        google()
    }
dependencies {
    .....
    implementation 'com.jph.takephoto:takephoto_library:4.0.3'
    //Glide图片显示
    implementation 'com.github.bumptech.glide:glide:4.9.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
}

②、Activity实现takephoto

/**
 * 实现Takephoto，InvokeListener。重写多个方法，添加获取实例方法getPhoto，对图片进行压缩裁剪等操作。
 */
public class GetPicture extends AppCompatActivity implements TakePhoto.TakeResultListener, InvokeListener {

    @BindView(R.id.iv_choose)
    ImageView ivChoose;
    @BindView(R.id.btn_photo)
    Button btnPhoto;
    @BindView(R.id.btn_picture)
    Button btnPicture;
    @BindView(R.id.btn_multiple_choice)
    Button btnMultipleChoice;
    @BindView(R.id.iv_choose2)
    ImageView ivChoose2;
    private TakePhoto takePhoto;
    private InvokeParam invokeParam;
    ArrayList<TImage> images;//返回的图片对象
    private int flag;//1-->打开相机（裁剪），2-->打开相册（裁剪），3-->打开相册（多选裁剪）

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        getTakePhoto().onCreate(savedInstanceState);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.get_picture);
        ButterKnife.bind(this);
    }


    /**

     * @return
     */
    public TakePhoto getTakePhoto() {
        if (takePhoto == null) {
            takePhoto = (TakePhoto) TakePhotoInvocationHandler.of(this).bind(new TakePhotoImpl(this, this));
        }
        //设置压缩规则，最大500kb
        takePhoto.onEnableCompress(new CompressConfig.Builder().setMaxSize(500 * 1024).create(), true);
        return takePhoto;
    }


    /**

     */
    private void takePhotoAndImage() {
        //图片保存路径

        CropOptions cropOptions = new CropOptions.Builder().setOutputX(size).setOutputX(size).setWithOwnCrop(false).create();
        if (flag == 1) {
            //相机获取照片并剪裁
            takePhoto.onPickFromCaptureWithCrop(uri, cropOptions);
            //相机获取不剪裁
            //takePhoto.onPickFromCapture(uri);
        } else if (flag == 2) {
            //相册获取照片并剪裁
            takePhoto.onPickFromGalleryWithCrop(uri, cropOptions);
            //相册获取不剪裁
//      takePhoto.onPickFromGallery();
        } else if (flag == 3) {

        }

    }


    @Override
