打开doc文件可以使用follow

public class MainActivity extends Activity {



     @Override

     public void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      setContentView(R.layout.activity_main);



      Button button = (Button) findViewById(R.id.bPressMe);



      button.setOnClickListener(new OnClickListener() {

       @Override

       public void onClick(View v) {



        File file = new File(Environment.getExternalStorageDirectory(),

          "Help Desk Voice Flow.doc");



        try {

         if (file.exists()) {

          Uri path = Uri.fromFile(file);

          Intent objIntent = new Intent(Intent.ACTION_VIEW);

          // replace "application/msword" with

          // "application/vnd.openxmlformats-officedocument.wordprocessingml.document"

          // for docx files

          // objIntent.setDataAndType(path,"application/msword");

          objIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

          startActivity(objIntent);

         } else {

          Toast.makeText(MainActivity.this, "File NotFound",

            Toast.LENGTH_SHORT).show();

         }

        } catch (ActivityNotFoundException e) {

         Toast.makeText(MainActivity.this,

           "No Viewer Application Found", Toast.LENGTH_SHORT)

           .show();

        } catch (Exception e) {

         e.printStackTrace();

        }

       }

      });



     }
