AndroidChannel
AndroidChannel is helper library for inter thread communication between main thread and worker thread. AndroidChannel uses HandlerThread for inter thread communication.
Setup Gradle
dependencies {
...
compile 'kr.pe.burt.android.lib:androidchannel:0.0.4'
}
Example
AndroidChannel-ProgressLayout
I have reimplemented ProgressLayout by using AndroidChannel for example. You can check out souce code at AndroidChannel-ProgressLayout. It shows how to use AndroidChannel when you want to implement a custom animatable view.
Ping-Pong
You can make a channel between main thread and worker thread easily.
channel = new AndroidChannel(new AndroidChannel.UiCallback() {
@Override
public boolean handleUiMessage(Message msg) {
if(msg.what == PING) {
Log.d("TAG", "PING");
channel.toWorker().sendEmptyMessageDelayed(PONG, 1000);
}
return false;
}
}
, new AndroidChannel.WorkerCallback() {
@Override
public boolean handleWorkerMessage(Message msg) {
if(msg.what == PONG) {
Log.d("TAG", "PONG");
channel.toUI().sendEmptyMessageDelayed(PING, 1000);
}
return false;
}
}
);
channel.toUI().sendEmptyMessage(PING);
Timer
If you use AndroidChannel, You can make Timer more easily. I already make Timer class for you. You can just use it. If you want to know how to implement Timer class, you just read souce code in the package.
timer = new Timer(1000, new Timer.OnTimer() {
int count = 0;
@Override
public void onTime(Timer timer) {
count++;
textView.setText("count : " + count);
}
}
);
timer.start();
You can also stop the timer like this.
@Override public boolean onTouchEvent(MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_UP) {
if(timer.isAlive()) {
timer.stop();
}
else {
timer.start();
}
}
return super.onTouchEvent(event);
}
APIs
- channel.open()
- Use open() method to open channel. If you created a channel by Channel constructor, it is automatically open the channel by default.
- channel.close()
- Use close() method to close channel. close() method removes callbacks and messages in the message queue.
- channel.toUI()
- toUI() method returns main thread handler. If you want to send messages to ui thread you should use toUI() method.
- channel.toWorker()
- toWorker() method returns worker thread handler. If you want to send messages to worker thread you should use toWorker() method.
