Start an activity
suggest changeThis example will start DestinationActivity
from OriginActivity
.
Here, the Intent
constructor takes two parameters:
- A Context as its first parameter (this is used because the Activity class is a subclass of Context)
- The Class of the app component to which the system should deliver the Intent (in this case, the activity that should be started)
public class OriginActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_origin);
Intent intent = new Intent(this, DestinationActivity.class);
startActivity(intent);
finish(); // Optionally, you can close OriginActivity. In this way when the user press back from DestinationActivity he/she won't land on OriginActivity again.
}
}
Another way to create the Intent
to open DestinationActivity
is to use the default constructor for the Intent
, and use the setClass()
method to tell it which Activity to open:
Intent i=new Intent();
i.setClass(this, DestinationActivity.class);
startActivity(intent);
finish(); // Optionally, you can close OriginActivity. In this way when the user press back from DestinationActivity he/she won't land on OriginActivity
Found a mistake? Have a question or improvement idea?
Let me know.
