Step 1: Create Gesture
attribute in the Activity
:
private Gesture gesture;
Step 2: Initialize Gesture
object and add GestureListner
:
gesture = new Gesture();
gesture.addListener(new GestureListener() {
@Override public void onPress(MotionEvent motionEvent) {
textView.setText("press");
}
@Override public void onTap(MotionEvent motionEvent) {
textView.setText("tap");
}
@Override public void onDrag(MotionEvent motionEvent) {
textView.setText("drag");
}
@Override public void onMove(MotionEvent motionEvent) {
textView.setText("move");
}
@Override public void onRelease(MotionEvent motionEvent) {
textView.setText("release");
}
@Override public void onLongPress(MotionEvent motionEvent) {
textView.setText("longpress");
}
@Override public void onMultiTap(MotionEvent motionEvent, int clicks) {
textView.setText("multitap [" + clicks + "]");
}
});
Step 3: Override dispatchTouchEvent(MotionEvent)
method:
@Override public boolean dispatchTouchEvent(MotionEvent event) {
gesture.dispatchTouchEvent(event);
return super.dispatchTouchEvent(event);
}
Step 1: Create Gesture
attribute and Subscription
in the Activity
:
private Gesture gesture;
private Disposable subscription;
Step 2: Initialize Gesture
object and subscribe RxJava Observable
:
gesture = new Gesture();
subscription = gesture.observe()
.subscribeOn(Schedulers.computation())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(event -> {
textView.setText(event.toString());
});
GestureEvent
is an enum with the following API:
public enum GestureEvent {
ON_PRESS,
ON_TAP,
ON_DRAG,
ON_MOVE,
ON_RELEASE,
ON_LONG_PRESS,
ON_MULTI_TAP;
int getClicks();
GestureEvent withClicks(int clicks);
}
Step 3: Override dispatchTouchEvent(MotionEvent)
method:
@Override public boolean dispatchTouchEvent(MotionEvent event) {
gesture.dispatchTouchEvent(event);
return super.dispatchTouchEvent(event);
}
Step 4: Don't forget to dispose subscription when it's no longer needed:
@Override protected void onPause() {
super.onPause();
if (subscription != null && !subscription.isDisposed()) {
subscription.dispose();
}
}

You can depend on library through Maven:
<dependency>
<groupId>com.github.pwittchen</groupId>
<artifactId>gesture-rx2</artifactId>
<version>x.y.z</version>
</dependency>
or through Gradle:
dependencies {
compile 'com.github.pwittchen:gesture-rx2:x.y.z'
}
To execute unit tests run:
./gradlew test
Code style used in the project is called SquareAndroid
from Java Code Styles repository by Square available at: https://github.com/square/java-code-styles.
Static code analysis runs Checkstyle, FindBugs, PMD and Lint. It can be executed with command:
./gradlew check
Reports from analysis are generated in library/build/reports/
directory.
