我尝试实现对存储进行写入和读取的请求权限。一切都运行得很好,但今天Android向我展示了RequestPermissionsResult(...)已弃用。StackOverflow上有这么多关于这个主题的问题,但不幸的是,它们已经过时了。
我在片段中调用了下面的方法。
有人建议简单地打个电话:
requestPermissions(new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE},
StorageKeys.STORAGE_PERMISSION_CODE)
而不是我的方法:
ActivityCompat.requestPermissions(getActivity(),
new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE},
StorageKeys.STORAGE_PERMISSION_CODE))
但它们都显示onRequestPermissionsResult(...)已弃用。
以下是我的onRequestPermissionsResult(...)-方法:
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
@NonNull int[] grantResults) {
if (requestCode == StorageKeys.STORAGE_PERMISSION_CODE) {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
exportBibTex.createBibFile();
exportBibTex.writeBibFile(exportBibTex
.getBibDataLibrary(libraryModel, bookDao, noteDao));
Toast.makeText(getContext(),
getString(R.string.exported_file_stored_in) + 'n'
+ File.separator + StorageKeys.DOWNLOAD_FOLDER + File.separator + fileName
+ StorageKeys.BIB_FILE_TYPE, Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getContext(), R.string.storage_permission_denied,
Toast.LENGTH_SHORT).show();
}
}
}
下面是一个简单的警告对话框,我在其中调用onRequestPermissionsResult(...):
private void showRequestPermissionDialog() {
AlertDialog.Builder reqAlertDialog = new AlertDialog.Builder(getContext());
reqAlertDialog.setTitle(R.string.storage_permission_needed);
reqAlertDialog.setMessage(R.string.storage_permission_alert_msg);
reqAlertDialog.setPositiveButton(R.string.ok,
(dialog, which) -> ActivityCompat.requestPermissions(getActivity(),
new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE},
StorageKeys.STORAGE_PERMISSION_CODE));
reqAlertDialog.setNegativeButton(R.string.cancel,
(dialog, which) -> dialog.dismiss());
reqAlertDialog.create().show();
}
我可以使用onRequestPermissionsResult(...)的替代方法吗?
