Android打開文件方法

通過MIME type的不同用系統含有的程序打開

1. Uri uri = Uri.parse("file://" + filePath);
2. Intent intent = new Intent();
3. intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
4. intent.setAction(Intent.ACTION_VIEW);
5. String type = Common.getMIMEType(filePath);
6. intent.setDataAndType(uri, type);
7. if (!type.equals("*/*"))
8. {
9. startActivity(intent);
10. } else
11. {
12. showOpenTypeDialog(filePath);
13. }

Common.getMIMEType(filePath)代碼：

1. /**
2. * 獲取文件類型
3. */
4. public static String getMIMEType(String filePath)
5. {
6. String type = "*/*";
7. String fName = filePath;
9. int dotIndex = fName.lastIndexOf(".");
10. if (dotIndex < 0)
11. {
12. return type;
13. }
15. String end = fName.substring(dotIndex, fName.length()).toLowerCase();
16. if (end == "")
17. {
18. return type;
19. }
21. for (int i = 0; i < MIME_MapTable.length; i++)
22. {
23. if (end.equals(MIME_MapTable[i][0]))
24. {
25. type = MIME_MapTable[i][1];
26. }
27. }
28. return type;
29. }

MIME_MapTable 代碼：

1. /**
2. * MIME 列表
3. */
4. public static final String[][] MIME_MapTable =
5. {
6. // {後綴名， MIME類型}
