When receiving, override method:Onactivityresult
In the child activity, write the data using the method:Setresult

Mainactivity Code:

 PrivateTextView TV; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate); Setcontentview (R.layout.activity_main); Findviewbyid ( Setonclicklistener (NewView.onclicklistener () {@Override Public voidOnClick (view view) {Intent I=NewIntent (mainactivity. This, Othereactivity.class); Startactivityforresult (i,0);//start the receive in this way, the second one is the request code    }}); } @Overrideprotected voidOnactivityresult (intRequestcode,intResultCode, Intent data) {        Super. Onactivityresult (Requestcode, ResultCode, data); TV=(TextView) Findviewbyid (; Tv.settext ("The other activity returned is:" +data.getstringextra ("Data")); }
