Simple dependency injection for Android.
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
compile 'com.github.rrigoni:KISS:1.0.0'
}
In your Application class init the modules:
public class App extends Application{
@Override
public void onCreate() {
super.onCreate();
KISS.with(new APIModule());
}
}Your app module should look like this:
public class APIModule {
@Service
public APIService apiService(){
return new APIServiceImpl();
}
@Service
public ExampleService exampleService(@InjectService APIService apiService){
return new ExampleService() {};
}
}
```
To prevent add the inject command in all activities, create a GenericActivity and extends it:
```java
public class GenericActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
KISS.inject(this);
}
}
```
In your activities innject everything you need like this:
```java
@InjectContentView(R.layout.activity_main)
public class MainActivity extends GenericActivity implements ItemFragment.OnListFragmentInteractionListener{
@InjectView(R.id.textview) TextView textView;
@InjectView(R.id.edittext) EditText editText;
@InjectView(R.id.buttom) Button button;
@InjectDrawable(R.drawable.twitter) Drawable twitterLogo;
@InjectManager(LOCATION_SERVICE) LocationManager locationManager;
@InjectString(R.string.testString) String testString;
@InjectService APIService apiModule;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragment_container, ItemFragment.newInstance(1))
.commit();
}
@Click(R.id.buttom)
private void onButtonClick(){
Toast.makeText(this, "Click", Toast.LENGTH_SHORT).show();
}
@Key(R.id.edittext)
private void keyEventListener(){
Toast.makeText(this, "Key event", Toast.LENGTH_SHORT).show();
}
@Override
public void onListFragmentInteraction(DummyContent.DummyItem item) {
}
}
```
Wait, and fragments?
```java
public class ItemFragment extends Fragment {
private OnListFragmentInteractionListener mListener;
public ItemFragment() {
}
public static ItemFragment newInstance(int columnCount) {
return new ItemFragment();
}
@InjectView(R.id.list) private RecyclerView recyclerView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_item_list, container, false);
KISS.inject(this, view);
Context context = view.getContext();
recyclerView.setLayoutManager(new GridLayoutManager(context, 1));
recyclerView.setAdapter(new MyItemRecyclerViewAdapter(DummyContent.ITEMS, mListener));
return view;
}
public interface OnListFragmentInteractionListener {
void onListFragmentInteraction(DummyItem item);
}
}
```
Wait, and viewholders?
```java
public class ViewHolder extends RecyclerView.ViewHolder {
@InjectView(R.id.id2) public View mView;
@InjectView(R.id.content2) public TextView mIdView;
@InjectView(R.id.content2) public TextView mContentView;
public DummyItem mItem;
public ViewHolder(View view) {
super(view);
mView = view;
KISS.inject(this, view);
}
}
