  1. setMaxSize(size: Int) 设置最大选择文件个数
  2. setType(type: PickerType) 设置类型
    • PickerType.Image = 图片
    • PickerType.Video = 视频
    • PickerType.ImageAndVideo = 图片 + 视频 混合选择
  3. setCameraEnable(enable: Boolean) 设置是否启动拍摄功能,默认=true
  4. setMaxVideoLength(length: Int) 当类型=Video时,可以选择视频最大时长限制,单位:秒 默认=-1 无限制
  5. setMaxListSize(size: Int) 最长列表加载长度,防止图片过多时产生OOM -1=不限制 默认限制长度=1000条
// 在图片选择器Activity创建时会回调这个方法,一般会通过这个来改变导航栏、状态栏的Theme,demo中搭配`ImmersionBar`来实现沉浸式效果

通过继承实现接口IImageLoader ,并注册到服务MXImagePicker即可

// 数据对象
data class MXItem(val path: String, val time: Long, val type: MXPickerType, val duration: Int = 0)

// 全局注册加载器,可以卸载Application里面,不影响启动速度
MXImagePicker.registerImageLoader { activity, item, imageView ->
   if (File(item.path).exists()) {
   } else if (item.path.startsWith("http")) {
   } else {


override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
   super.onActivityResult(requestCode, resultCode, data)
   if (resultCode == RESULT_OK && requestCode == 0x22) {
      val paths = MXPickerBuilder.getPickerResult(data) ?: return //返回List<String>类型数据


val builder = MXCaptureBuilder().setType(MXPickerType.Image)

startActivityForResult(builder.createIntent(this), 0x11)

// 在onActivityResult获取结果
val file = builder.getCaptureFile()


val builder = MXCaptureBuilder().setType(MXPickerType.Video).setMaxVideoLength(10)
startActivityForResult(builder.createIntent(this), 0x11)

// 在onActivityResult获取结果
val file = builder.getCaptureFile()
