/**Click to jump to the system gallery and display the selected pictures to the app*/ Public classMainactivityextendsActivity {PrivateImageView IV; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.layout.activity_main); IV=(ImageView) Findviewbyid (R.ID.IV); }    //Click the Jump button     Public voidClick (View v) {Intent Intent=NewIntent ();        Intent.setaction (Intent.action_pick); Intent.settype ("Image/*"); Startactivityforresult (Intent,2); } @Overrideprotected voidOnactivityresult (intRequestcode,intResultCode, Intent data) {        Super. Onactivityresult (Requestcode, ResultCode, data); if(requestcode==2){            if(data!=NULL){//prevent users from not selecting pictures, back when software crashesUri uri =Data.getdata ();            Iv.setimageuri (URI); }        }    }}

This is the result.
