我尝试了很多代码来在 android 11 或 12 中获取 pdf 路径,但仅适用于 android 10 或更低的设备。你能帮我么?我分享我的行代码
像这样的意图调用
Intent intent = new Intent();
intent.setType("application/pdf");
statusAdapter = "pdf";
pos = position;
intent.setAction(Intent.ACTION_GET_CONTENT);
someActivityResultLauncher.launch(Intent.createChooser(intent, "Select PDF"));

someActivityResultLauncher = registerForActivityResult(
new ActivityResultContracts.StartActivityForResult(),
result -> {
if (result.getResultCode() == Activity.RESULT_OK) {
// There are no request codes
Intent data = result.getData();
if (data == null) {
//error
return;
}
try {
final Uri pdfUri= data.getData();
File pdfFile = new File(getPath(pdfUri));
long length = pdfFile.length();
length = length / 1024;
Toast.makeText(CreateSubEventActivity.this, "File Path : " + pdfFile.getPath() + ", File size : " + length + " KB", Toast.LENGTH_SHORT).show();
// uploadFile(imageFile);
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(CreateSubEventActivity.this, "Something went wrong", Toast.LENGTH_LONG).show();
}
}
});

getPath 像这样调用
public String getPath(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
if (cursor == null) return null;
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String s = cursor.getString(column_index);
cursor.close();
return s;
}
