Android intent's main usage-text message, phone call, and MMS

 

Android intent usage

1. Start a new Activity

1. Intent it = new Intent (Activity. Main. this, Activity2.class );
2. StartActivity (it );

2. pass data to the next Activity (use Bundle and Intent. putExtras)

1. Intent it = new Intent (Activity. Main. this, Activity2.class );
2. Bundle bundle = new Bundle ();
3. Bundle. putString ("name", "This is from MainActivity! ");
4. It. putextras (bundle); // it. putextra ("test", "shuju ");
5. Startactivity (it); // startactivityforresult (it, request_code );

You can use the following methods to obtain data:

1. Bundle bundle = getintent (). getextras ();
2. String name = bundle. getstring ("name ");

3. Return the result to the previous activity (use setresult to start the activity for startactivityforresult (it, request_code)

1. Intent intent = getintent ();
2. Bundle bundle2 = new bundle ();
3. Bundle2.putstring ("name", "this is from showmsg! ");
4. Intent. putextras (bundle2 );
5. Setresult (result_ OK, intent );

4. Call back the result processing function (onactivityresult) of the previous activity)

1. @ Override
2. Protected void onactivityresult (INT requestcode, int resultcode, intent data ){
3. // Todo auto-generated method stub
4. Super. onactivityresult (requestcode, resultcode, data );
5. If (requestcode = request_code ){
6. If (resultcode = result_canceled)
7. Settitle ("cancle ");
8. Else if (resultcode = result_ OK ){
9. String temp = NULL;
10. Bundle bundle = data. getextras ();
11. If (bundle! = NULL) temp = bundle. getstring ("name ");
12. SetTitle (temp );
13. }
14. }
15. }

Call number:
Call the dialup Program

1. Uri uri = URI. parse ("Tel: xxxxxx ");
