Piri is a lightweight annotation processing library that generates static factory methods for your Activities and Fragments.
Add PiriActivity annotation to your Activity.
@PiriActivity
public class YourActivity extends AppCompatActivity {
...
}And start YourActivity from another Activity.
public class MainActivity extends AppCompatActivity {
...
navButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
final Intent intent = PiriIntentFactory.newIntentForYourActivity(MainActivity.this);
startActivity(intent);
}
});
...
}If you want to pass data to YourActivity with Piri add PiriParam annotation to your fields in your Activity and receive data from bundle.
@PiriActivity
public class YourActivity extends AppCompatActivity {
@PiriParam(key = "extra_id")
private Long id;
@PiriParam(key = "extra_name")
private String name;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_your);
final Bundle bundle = getIntent().getExtras();
if (bundle != null) {
id = bundle.getLong("extra_id");
name = bundle.getString("extra_name");
}
// INIT UI
...
}
}And start YourActivity like the following:
public class MainActivity extends AppCompatActivity {
...
final Long id = 1234567890L;
final String name = "PiriExample";
navButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
final Intent intent = PiriIntentFactory.newIntentForYourActivity(MainActivity.this,id,name);
startActivity(intent);
}
});
...
}Add PiriFragment annotation to your Fragments.
@PiriFragment
public class SampleFragment extends Fragment{
private static final String EXTRA_ID = "extra_id";
private static final String EXTRA_USER = "extra_user";
private static final String EXTRA_BOOK = "extra_book";
@PiriParam(key = EXTRA_ID)
private Long id;
@PiriParam(key = EXTRA_USER)
private User user;
@PiriParam(key = EXTRA_BOOK)
private Book book;
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final Bundle args = getArguments();
if (args != null) {
id = args.getLong(EXTRA_ID, 0);
user = args.getParcelable(EXTRA_USER);
book = (Book) args.getSerializable(EXTRA_BOOK);
}
}
}
