如何以编程方式使用Intents打开文件？

Question

I have following code for opening files programatically:

    Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, type);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

But now I need to set MIME-type of file, and it isn't universal method for all files. Is there any mean for opening file through Intent without defining type?

Answer 1

Sure, just use intent.setData() , instead of intent.setDataAndType() . Although, the result may not be as desirable as when the type is defined.

You can also use a convenience Intent constructor, and remove the "setData" call, like so:

Intent intent = new Intent(Intent.ACTION_VIEW, path);
