【Android -- 相机】TakePhoto 实现拍照、相册以及裁剪图片

一、简介

TakePhoto 是一款用于在 Android 设备上获取照片（拍照或从相册、文件中选择）、裁剪图片、压缩图片的开源工具库，目前最新版本 4.0.3。

• 使用自带的相机 APP 拍照
• 系统相册选择照片
• 系统相机或相册获取的照片裁剪

二、效果图

三、使用

1. 添加依赖

    // 申请权限
    implementation 'com.tbruyelle.rxpermissions2:rxpermissions:+'
    implementation 'com.jph.takephoto:takephoto_library:4.0.3'
    //glide
    implementation 'com.github.bumptech.glide:glide:4.12.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.12.0'

2. 清单文件中添加权限

3. popup_take_photo.xml

4. 代码逻辑 (1) 继承 TakePhotoActivity (2) 重写 takeSuccess，takeFail，takeCancel 方法 (3) 设置动态权限，适配6.0以上设备

public class PersonalInfoActivity extends TakePhotoActivity {
    @BindView(R.id.iv_head)
    ImageView headImg;

    private CommonPopupWindow popupWindow;
    private TakePhoto takePhoto;
    private CropOptions cropOptions;    //裁剪参数
    private CompressConfig compressConfig;  //压缩参数
    private Uri imageUri;

    private static final String[] permissionsGroup = new String[]{
            Manifest.permission.CALL_PHONE,
            Manifest.permission.CAMERA,
            Manifest.permission.WRITE_EXTERNAL_STORAGE};

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_personal_info);
        ButterKnife.bind(this);
        initView();

        //设置裁剪参数
        cropOptions = new CropOptions.Builder().setAspectX(1).setAspectY(1).setWithOwnCrop(false).create();

        //设置压缩参数
        compressConfig = new CompressConfig.Builder().setMaxSize(50 * 1024).setMaxPixel(800).create();
        takePhoto.onEnableCompress(compressConfig, true);    //设置为需要压缩
    }

    private void initView() {
        checkPermissionRequest();
