AndroidManifest.xml中添加以下代码 * 注：注意provider androidx的差别 3. 6.0+需处理权限 The library requires two permissions: - `android.permission.READ_EXTERNAL_STORAGE` - `android.permission.WRITE_EXTERNAL_STORAGE` 4. 为适配7.0，,项目manifest的privider标签下 paths文件中添加 文件名称为file_paths_public（名字随意取，但需与AndroidManifest.xml中引用保持一致） | Default Style | Other Style Preview | Preview | |:------------------------------:|:---------------------------------:|:--------------------------------:| |![](image/screenshot_default.jpg) | ![](image/screenshot_other.jpg) | ![](image/screenshot_preview.jpg)| | Circle Crop | Square Crop | |:------------------------------:|:---------------------------------:| |![](image/screenshot_circlecrop.jpg) | ![](image/screenshot_squarecrop.jpg) | #### Simple usage snippet ------ ### 配置主题. | Media theme | Preview theme | |:------------------------------:|:---------------------------------:| |![](image/media_theme_describe.png) | ![](image/preview_theme_describe.png) | 使用套路与原项目一致，只是多增加了一些参数，另外定制时需配置所提供的所有参数。 使用主题时可直接使用Matisse.Default， 或者在自己项目中另写style继承自Matisse.Default，修改自己所需属性，如下 ``` app/style.xml ``` ``` matisse/style.xml 如需定制UI样式 按需修改，否则使用上述默认主题 Matisse.from(this@MainActivity) .setStatusIsDark(true) // 按需设置状态栏文字颜色 .theme(R.style.Matisse_Default) // 设置成所需主题 ``` ### 注意：1.1.1版本支持外部设置设置状态栏颜色，关于状态栏与状态栏底色问题 ##### 项目内部 仅添加了该库(`compileOnly 'com.gyf.barlibrary:barlibrary:2.3.0'`)的编译 需要根据样式修改状态栏文字颜色，图片预览界面状态栏隐藏功能，需在自己项目中引入该库 ``` Matisse.from(this@MainActivity) ... .setStatusIsDark(true) // 设置状态栏文字颜色 true=黑色 false=白色 .theme(R.style.Matisse_Default) // 设置成所需主题 ... ``` Start `MatisseActivity` from current `Activity` or `Fragment`: ``` kotlin项目调用 Matisse.from(MainActivity.this) .choose(MimeTypeManager.ofAll(), false) .countable(true) .maxSelectable(9) .addFilter(new GifSizeFilter(320, 320, 5 * Filter.K * Filter.K)) .gridExpectedSize(getResources().getDimensionPixelSize(R.dimen.grid_expected_size)) .restrictOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED) .thumbnailScale(0.85f) .imageEngine(new GlideEngine()) .forResult(REQUEST_CODE_CHOOSE); java项目调用 Matisse.Companion.from(MainActivity.this) .choose(MimeTypeManager.Companion.ofAll(), false) .countable(true) .maxSelectable(9) .addFilter(new GifSizeFilter(320, 320, 5 * Filter.K * Filter.K)) .gridExpectedSize(getResources().getDimensionPixelSize(R.dimen.grid_expected_size)) .restrictOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED) .thumbnailScale(0.85f) .imageEngine(new GlideEngine()) .forResult(REQUEST_CODE_CHOOSE); Matisse.from(SampleActivity.this) .choose(MimeTypeManager.ofAll(), false) // 展示所有类型文件（图片 视频 gif） .capture(true) // 可拍照 .countable(true) // 记录文件选择顺序 .captureStrategy(new CaptureStrategy(true, "cache path")) .maxSelectable(1) // 最多选择一张 .isCrop(true) // 开启裁剪 .isCircleCrop(true) // 设置裁剪类型 .addFilter(new GifSizeFilter(320, 320, 5 * Filter.K * Filter.K)) // 筛选数据源可选大小限制 .gridExpectedSize(getResources().getDimensionPixelSize(R.dimen.grid_expected_size)) .restrictOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) .thumbnailScale(0.8f) .setStatusIsDark(true) // 设置状态栏文字颜色 需依赖ImmersionBar库 .imageEngine(new GlideEngine()) // 加载库需外部实现 .forResult(REQUEST_CODE_CHOOSE); ``` 为方便后期兼容Fresco，图片加载类需外部实现 **注意：**目前慎用Fresco（尽管提供了栗子）！！！，图片加载兼容了Fresco，***但，图片放大预览并未兼容*** ``` class Glide4Engine : ImageEngine { override fun cleanMemory(context: Context) { if (Looper.myLooper() == Looper.getMainLooper()) { Glide.get(context).clearMemory() } } override fun pause(context: Context) { Glide.with(context).pauseRequests() } override fun
