如何将ActivityResultContract.GetContent限制为媒体(图像或视频)

Question

有没有办法让ActivityResultContract.GetContent只过滤媒体文件？

private val selectMediaResultLauncher = registerForActivityResult(ActivityResultContracts.GetContent()) { uri: Uri? ->
// Do something with the uri
}

尝试使用：

selectMediaResultLauncher.launch("image/* video/*")

但运气不好。

谢谢你的协助。

您可以使用OpenDocument((

private val selectMediaResultLauncher = registerForActivityResult(ActivityResultContracts.OpenDocument()) { uri ->
// Do something with the uri
}

和：

selectMediaResultLauncher.launch(arrayOf("image/*", "video/*"))
