JarCastingAndroid Binder
This project is a simple annotation based model to view binder.
Installation
Add as a dependency to your build.gradle:
dependencies {
compile 'com.kendamasoft.binder:0.9.7'
}
Simple Injection
class MyActivity extends Activity {
@Inject(R.id.textView)
TextView text;
@Inject({R.id.icon1, R.id.icon2, R.id.icon3})
List<ImageView> icons;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
Binder.register(this);
text.setText("Hello World");
}
@Override
protected void onDestroy() {
super.onDestroy();
Binder.unregister(this);
}
}
Binding and callbacks
class MyModel extends Observable {
@Bind(R.id.editText)
String text = "World!";
@Bind(R.id.textView)
String description = "Hello";
@Inject(R.id.button)
private Button button;
public void setText(String text) {
this.text = text;
notifyFieldChange("text");
}
public void setDescription(String description) {
this.description = description;
notifyFieldChange("description");
}
@Callback(R.id.checkBox)
public void setEnabled(boolean enabled) {
button.setEnabled(enabled);
}
}
class MyActivity extends Activity {
@Model
MyModel model;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
Binder.register(this);
model.setEnabled(false);
}
@OnClick(R.id.button)
void onTestButtonClick() {
model.setDescription("Hello World!");
}
}
List View Helper
class TestListModelHelper extends ViewHolderHelper<TestListModel> {
@Inject(R.id.textViewName)
TextView nameView;
@Inject(R.id.textViewDescription)
TextView descriptionView;
@Override
public void applyView(TestListModel model, View rootView) {
nameView.setText(model.name);
descriptionView.setText(model.description);
}
}
class MyActivity extends Activity {
List<TestListModelHelper> listModel = new ArrayList<>();
@Inject(R.id.listView)
ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
Binder.register(this);
...
listView.setAdapter(new ListViewAdapter<>(this, R.layout.list_item_test, TestListBinder.class, listModel));
}
}
Unregister
Call Binder.unregister(...) to clean everything up. Good place for this call is onDestroy() methods.
