我想使用Intent打开特定的路径文件夹,我使用File explorer的代码,它在一些设备(三星设备)中工作得很好,如果文件浏览器应用程序不可用,那么它不会打开特定路径的文件夹。 我尝试了很多解决方案,但这对我不起作用。
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"));
}
答案 0 :(得分:1)
val intent = Intent(Intent.ACTION_GET_CONTENT)
intent.setDataAndType(
Uri.parse(
(Environment.getExternalStorageDirectory().path
+ java.io.File.separator) + "myFile" + java.io.File.separator
), "*/*"
)
intent.addFlags(
Intent.FLAG_GRANT_READ_URI_PERMISSION
and Intent.FLAG_GRANT_WRITE_URI_PERMISSION
and Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION
and Intent.FLAG_GRANT_PREFIX_URI_PERMISSION
)
intent.addCategory(Intent.CATEGORY_OPENABLE)
startActivityForResult(intent, WRITE_ACCESS_CODE)

这是我在 Kotlin
中访问“ root / Downloads / Sam”的解决方案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)
}
