分享一些传值的组件

IntentBuilder

@IntentBuilder
class DetailActivity extends Activity {
    
    @Extra
    String id;

    @Extra @Nullable
    String title;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        DetailActivityIntentBuilder.inject(getIntent(), this);
        // TODO use id and title
    }

startActivity(new DetailActivityIntentBuilder("12345")
    .title("MyTitle")
    .build(context))
}

@IntentBuilder
class DownloadService extends IntentService {

    @Extra
    String downloadUrl;
    
    @Override
    protected void onHandleIntent(Intent intent) {
        MyServiceIntentBuilder.inject(intent, this);
    }

}

startService(new DownloadServiceIntentBuilder("http://google.com").build(context))

OnActivityResult

@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    ActivityResult.onResult(requestCode, resultCode, data).into(this);
}

@OnActivityResult(requestCode = 33)
void onActivityResultTestActivity() { /* Do something */ }

@OnActivityResult(requestCode = 1, resultCodes = { Activity.RESULT_OK })
void onActivityResultActivityOk() { /* Only do something when ok */ }

@OnActivityResult(requestCode = 1, resultCodes = { Activity.RESULT_CANCELED })
void onActivityResultActivityCanceled() { /* Only do something when canceled */ }

@OnActivityResult(requestCode = 2)
void onActivityResultPickImage(final int resultCode, final Intent intent) { /* Do something */ }

支持各种参数

• none
• int
• Intent
• int, Intent
• Intent, int

每个注解的方法只能有一个int和/或意图变量

FragmentArgs

@FragmentWithArgs
public class MyOptionalFragment extends Fragment {

    @Arg
    int id;
    
    @Arg
    String title;
    
    @Arg(required = false) 
    String additionalText;
    
    @Arg(required = false)
    float factor;
    
    @Arg(required = false)
    int mFeatureId;

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        FragmentArgs.inject(this); // read @Arg fields
    }
    
}

public class MyActivity extends Activity {

    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        
        int id = 123;
        String title = "test";
        
        // Using the generated Builder
        Fragment fragment = 
            new MyFragmentBuilder(id, title) // required args
            .additionalText("foo")  // Optional arg
            .factor(1.2f)           // Optional arg
            .featureId(42)          // Optional arg
            .build();
        
        
        // Fragment Transaction
        getFragmentManager()
            .beginTransaction()
            .replace(R.id.container, fragment)
            .commit();
    }

}
