android - How to start new activity on button click -

-

in android application, how start new activity (gui) when button in activity clicked, , how pass data between these 2 activities?

easy.

intent myintent = new intent(currentactivity.this, nextactivity.class); myintent.putextra("key", value); //optional parameters currentactivity.this.startactivity(myintent);

extras retrieved on other side via:

@override protected void oncreate(bundle savedinstancestate) {     intent intent = getintent();     string value = intent.getstringextra("key"); //if it's string stored. }

don't forget add new activity in androidmanifest.xml:

<activity android:label="@string/app_name" android:name="nextactivity"/>
