问题描述
我想使用Intent打开特定路径的文件夹,我使用了文件资源管理器的代码,它可以正常工作,但是在某些设备(三星设备)中,如果文件资源管理器应用程序不可用,则无法打开特定路径的文件夹.我尝试了许多解决方案,但对我而言不起作用.
I want to open specific path folder using Intent, I used code for File explorer and It working perfectly but in some device (samsung devices) if file explorer app are not available then It not opening folder of specific path. I tried many solutions but It won't work for me.
Uri uri = Uri.fromFile(new File(new File(filePath).getParent()));
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "resource/folder");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setDataAndType(uri, "file/*");
startActivity(Intent.createChooser(intent, "Open folder"));
}
推荐答案
这是我访问"root/Downloads/Sam"的解决方案.在科特林
Here is my solution for accessing "root/Downloads/Sam" in Kotlin
val rootPath = "content://com.android.externalstorage.documents/document/primary:"
val samPath = Uri.parse("$rootPath${Environment.DIRECTORY_DOWNLOADS}%2fSam") //"%2f" represents "/"
val REQUEST_CODE_PICK_FILE = 1
main_sam_button.setOnClickListener {
val intent = Intent(Intent.ACTION_GET_CONTENT)
intent.type = "text/plain" //specify file type
intent.putExtra(DocumentsContract.EXTRA_INITIAL_URI, samPath) //set the default folder
startActivityForResult(intent, REQUEST_CODE_PICK_FILE)
}
