功能介绍

将 MeiqiaSDK-Android 里的图库单独抽出来开源，将其中的 GridView、ListView 和 RelativeLayout 换成 RecyclerView 和 Toolbar，方便在以后的项目中直接依赖使用。Demo 中模仿了微信朋友圈的部分功能，详细用法请查看 Demo。希望能该库帮正在做这几个功能的猿友节省开发时间。

• [x] 单图选择
• [x] 多图选择
• [x] 拍照选择
• [x] 图片选择预览（支持微博长图）、缩放查看
• [x] 图片预览（支持微博长图）、缩放查看
• [x] 支持 glide、picasso、universal-image-loader、xutils 图片加载库
• [x] 支持配置列表滚动时是否暂停加载图片，列表停止滚动时恢复加载图片(用 xutils 作为图片加载库时该配置无效)
• [x] 正方形、圆形头像、带边框的圆形头像控件
• [x] 朋友圈列表界面的九宫格图片控件
• [x] 发布朋友圈界面的可拖拽排序的九宫格图片控件
• [x] 覆盖相应的资源文件来定制界面
• [x] BGAPhotoHelper 图片裁剪、拍照

使用

1.添加 Gradle 依赖

• 把 maven { url 'https://jitpack.io' } 添加到 root build.gradle 的 repositories 中
• 在 app build.gradle 中添加如下依赖，末尾的「latestVersion」指的是徽章 里的版本名称，请自行替换

由于需要支持微博长图预览，该库中已经引入了 PhotoView 的源码并进行了修改，所以你的项目中就不要再重复引入 PhotoView 了

dependencies {
    // -------------------- 以下4个库是必须依赖的 ----------------------------
    implementation 'com.github.bingoogolapple:BGAPhotoPicker-Android:latestVersion'
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'androidx.recyclerview:recyclerview:1.0.0'
    implementation 'com.github.bingoogolapple:BGABaseAdapter-Android:2.0.1'
    // -------------------- 以上4个库是必须依赖的 ----------------------------

    // 目前支持常见的 4 种图片加载库，必须在下面四个图片加载库中选择一个添加依赖
    implementation 'com.github.bumptech.glide:glide:4.10.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.10.0'
//    implementation 'com.squareup.picasso:picasso:2.5.2'
//    implementation 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
//    implementation 'org.xutils:xutils:3.8.3'
}

2.接口说明

BGAPhotoPickerActivity - 选择图片

@AfterPermissionGranted(PRC_PHOTO_PICKER)
private void choicePhotoWrapper() {
    String[] perms = {Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA};
    if (EasyPermissions.hasPermissions(this, perms)) {
        // 拍照后照片的存放目录，改成你自己拍照后要存放照片的目录。如果不传递该参数的话就没有拍照功能
        File takePhotoDir = new File(Environment.getExternalStorageDirectory(), "BGAPhotoPickerTakePhoto");

        Intent photoPickerIntent = new BGAPhotoPickerActivity.IntentBuilder(this)
                .cameraFileDir(mTakePhotoCb.isChecked() ? takePhotoDir : null) // 拍照后照片的存放目录，改成你自己拍照后要存放照片的目录。如果不传递该参数的话则不开启图库里的拍照功能
                .maxChooseCount(mPhotosSnpl.getMaxItemCount() - mPhotosSnpl.getItemCount()) // 图片选择张数的最大值
                .selectedPhotos(null) // 当前已选中的图片路径集合
                .pauseOnScroll(false) // 滚动列表时是否暂停加载图片
                .build();
        startActivityForResult(photoPickerIntent, RC_CHOOSE_PHOTO);
    } else {
        EasyPermissions.requestPermissions(this, "图片选择需要以下权限:\n\n1.访问设备上的照片\n\n2.拍照", PRC_PHOTO_PICKER, perms);
    }
}

BGAPhotoPickerActivity - 获取已选择的图片集合

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK && requestCode == RC_CHOOSE_PHOTO) {
        List<String> selectedPhotos = BGAPhotoPickerActivity.getSelectedPhotos(data);
    }
}

BGAPhotoPickerPreviewActivity - 预览已选择的图片

Intent photoPickerPreviewIntent = new BGAPhotoPickerPreviewActivity.IntentBuilder(this)
        .previewPhotos(models) // 当前预览的图片路径集合
        .selectedPhotos(models) // 当前已选中的图片路径集合
        .maxChooseCount(mPhotosSnpl.getMaxItemCount()) // 图片选择张数的最大值
        .currentPosition(position) // 当前预览图片的位置
        .isFromTakePhoto(false) // 是否是拍完照后跳转过来
        .build();
startActivityForResult(photoPickerPreviewIntent, RC_PHOTO_PREVIEW);

BGAPhotoPickerPreviewActivity - 获取预览界面已选择的图片集合

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_PHOTO_PREVIEW) {
        // 在预览界面按返回也会回传预览界面已选择的图片集合
        List<String> selectedPhotos = BGAPhotoPickerPreviewActivity.getSelectedPhotos(data);
    }
}

BGAPhotoPreviewActivity - 图片预览

@AfterPermissionGranted(PRC_PHOTO_PREVIEW)
private void photoPreviewWrapper() {
    String[] perms = {Manifest.permission.WRITE_EXTERNAL_STORAGE};
    if (EasyPermissions.hasPermissions(this, perms)) {
        File downloadDir = new File(Environment.getExternalStorageDirectory(), "BGAPhotoPickerDownload");
        BGAPhotoPreviewActivity.IntentBuilder photoPreviewIntentBuilder = new BGAPhotoPreviewActivity.IntentBuilder(this)
                .saveImgDir(downloadDir); // 保存图片的目录，如果传 null，则没有保存图片功能

        if (mCurrentClickNpl.getItemCount() == 1) {
            // 预览单张图片
            photoPreviewIntentBuilder.previewPhoto(mCurrentClickNpl.getCurrentClickItem());
        } else if (mCurrentClickNpl.getItemCount() > 1) {
            // 预览多张图片
            photoPreviewIntentBuilder.previewPhotos(mCurrentClickNpl.getData())
                    .currentPosition(mCurrentClickNpl.getCurrentClickItemPosition()); // 当前预览图片的索引
        }
        startActivity(photoPreviewIntentBuilder.build());
    } else {
        EasyPermissions.requestPermissions(this, "图片预览需要以下权限:\n\n1.访问设备上的照片", PRC_PHOTO_PREVIEW, perms);
    }
}

3.自定义样式

• 可以在你项目的 mipmap-xxhdpi 目录中添加 https://github.com/bingoogolapple/BGAPhotoPicker-Android/tree/master/library/src/main/res/mipmap-xxhdpi 中相应的同名图片文件来替换图片样式
• 可以在你项目的 colors.xml 文件中添加同名的颜色资源来自定义图片选择器的颜色
