对于该解决方案,我正在使用MediaStore提取所选文件的名称和扩展名.因此,我将 onActivityResult
中的代码替换为以下代码:
For the solution I am using the MediaStore to extract the name and extension of a choosen file. So I replace code in onActivityResult
with following code:
String path = new File(data.getData().getPath()).getAbsolutePath();
if(path != null){
uri = data.getData();
String filename;
Cursor cursor = getContentResolver().query(uri,null,null,null,null);
if(cursor == null) filename=uri.getPath();
else{
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Files.FileColumns.DISPLAY_NAME);
filename = cursor.getString(idx);
cursor.close();
}
String name = filename.substring(0,filename.lastIndexOf("."));
String extension = filename.substring(filename.lastIndexOf(".")+1);
}
因此,通过 MediaStore.File.FileColumns.DISPLAY_NAME
,可以从使用文件选择器选择的任何文件中获取文件名和扩展名.
So with MediaStore.File.FileColumns.DISPLAY_NAME
it's possible to get the file name and extension from any file choosen with a file chooser.
