Getting Started

Usage in Activity

Step 1 (Annotate)

• Annotate fields with @RequestParam for AndroidBus to transfer them to target Activity.
• Annotate class of target Activity with @ActivityBus and set the requestCode if your want to call startActivityForResult()

@ActivityBus(requestCode = 100)
public class TargetActivity extends AppCompatActivity {
    @RequestParam
    public int aInt;
    @RequestParam
    public String aString;
    @RequestParam
    public Person aPerson;
    @RequestParam
    public List<Person> aPersons;
    ...
}

Step 2 (transfer data)

Upon compilation, ActivityBus will generate a class such as TargetActivityBus ([Activity Name] + Bus), then call goActivity() to transfer the data in the FromActivity, here is MainActivity.

public class MainActivity extends AppCompatActivity {
...
TargetActivityBus.goActivity(this,1,"Hello",new Person("Entity"),personList);
...
}

Step 3 (get data)

Call register() before you useing the annotated fields.

@ActivityBus(requestCode = 100)
public class TargetActivity extends AppCompatActivity {
...
@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
        TargetActivityBus.register(this);
    }
...
}

Usage in Fragment

Usage in Fragment is more simple than in Activity,it only needs 2 steps.

Step 1 (Annotate)

public class TargetFragment extends Fragment {
    @RequestParam
    public int aInt;
    @RequestParam
    public String aString;
    ...
}

Step 2 (transfer data)

public class MainActivity extends AppCompatActivity {
...
TargetFragment targetFragment = TargetFragmentBus.newInstance(1,"Hello");
getSupportFragmentManager().beginTransaction().add(R.id.fl_fragment, targetFragment).commit();
...
}
