0.6.6 版本调整了自定义文件类型的实现。更加方便你使用自定义文件类型了!快来试试吧!
/**
* 1. 自定义文件类型。通过路径或文件名来判断是否符合类型
* 1. Customize the file type. Determine if it matches the type by path or filename.
*/
class CustomFileType(
override val fileType: String = "",
override val fileIconResId: Int = R.drawable.ic_unknown_file_picker
) : FileType {
override fun verify(fileName: String): Boolean {
return fileName.endsWith("123")
}
}
FilePickerManager.from(this@SampleActivity)
// register your custom file types. If your passing false, the lib would fill the type only and would not filter the list.
// Default is true.
// 注册您的自定义文件类型。 如果您传递的是false,则lib将仅填充类型,并且不会过滤列表。默认为true。
.registerFileType(arrayListOf(AudioFileType()), false)
.forResult(FilePickerManager.REQUEST_CODE)
这就搞定了!非常简单。XD
如果默认的文件类型无法满足您的需求,您只需要简单三步即可实现您自己的文件类型,并进行检测和过滤操作。 If the default file types don't meet your needs, you can implement your own file types, detection and filtering in three simple steps.
/**
* 1. 自定义文件类型。通过路径或文件名来判断是否符合类型
* 1. Customize the file type. Determine if it matches the type by path or filename.
*/
class CustomFileType(
override val fileType: String = "",
override val fileIconResId: Int = R.drawable.ic_unknown_file_picker
) : FileType {
override fun verify(fileName: String): Boolean {
return fileName.endsWith("123")
}
}
/**
* 2. 自定义文件检测器。
* 检测是否符合您的类型,如果是,那么填充到[FileItemBeanImpl.fileType]中
* 2. Custom file detector.
* detects if it matches your type, and if so, then fill it into [FileItemBeanImpl.fileType]
*/
class CustomFileDetector : AbstractFileDetector() {
private val customFileType by lazy { CustomFileType() }
override fun fillFileType(itemBeanImpl: FileItemBeanImpl): FileItemBeanImpl {
// detected file type by yourself and fill your type to [FileItemBeanImpl]
if (customFileType.verify(itemBeanImpl.fileName)) {
itemBeanImpl.fileType = customFileType
}
return itemBeanImpl
}
}
FilePickerManager
.from(this@SampleActivity)
// 1. 使用自定义文件检测器来检测类型,并赋值给 [FileItemBeanImpl.fileType] 属性
// 1. Using detector detect file's type and fill it into [FileItemBeanImpl.fileType]
.customDetector(CustomFileDetector())
.filter(object : AbstractFileFilter() {
override fun doFilter(listData: ArrayList<FileItemBeanImpl>): ArrayList<FileItemBeanImpl> {
// 2. 接收结果列表,然后过滤出您想要的类型
// 2. Receive result list and filter what you want
listData.removeAll {
(it.fileType !is CustomFileType) && !it.isDir
}
return listData
}
})
.showHiddenFiles(true)
.forResult(FilePickerManager.REQUEST_CODE)
