찾아보니 StandOut library가 거의 유일 하게 존재하여 대충 정리 ㅜㅜ
[StandOut library]
by pingpongboss
Intorduction : http://forum.xda-developers.com/showthread.php?t=1688531
Source code : https://github.com/pingpongboss/StandOut
Functionality
- Provide your own view. Very easy to integrate
- Window decorators (titlebar, minimize/close buttons, border, resize handle)
- Windows are moveable and resizable. You can bring-to-front, minimize, and close
- Minimized windows can be restored (the example APK demos this using the notification panel)
- Create multiple types of windows, and multiple windows of each type
- Continuously being developed. More coming.
Android Service를 상속한 StandOutWindow를 상속하여 각 창에 해당되는 window class를 생성하여 floating window를 보여주며 StandOut library 내에서 touch event를 각 view의 widget들에 전달할 수 있도록 처리하고 있음.
StandOutWindow class
: https://github.com/pingpongboss/StandOut/blob/master/library/src/wei/mark/standout/StandOutWindow.java
/**
* Extend this class to easily create and manage floating StandOut windows.
*
* @author Mark Wei <markwei@gmail.com>
*
* Contributors: Jason <github.com/jasonconnery>
*
*/
public abstract class StandOutWindow extends Service {
static final String TAG = "StandOutWindow";
Window class
: https://github.com/pingpongboss/StandOut/blob/master/library/src/wei/mark/standout/ui/Window.java
/**
* Special view that represents a floating window.
*
* @author Mark Wei <markwei@gmail.com>
*
*/
public class Window extends FrameLayout {
public static final int VISIBILITY_GONE = 0;
public static final int VISIBILITY_VISIBLE = 1;
public static final int VISIBILITY_TRANSITION = 2;
static final String TAG = "Window";
/**
* Class of the window, indicating which application the window belongs to.
*/
public Class<? extends StandOutWindow> cls;
...생략
/**
* Context of the window.
*/
private final StandOutWindow mContext;
private LayoutInflater mLayoutInflater;
public Window(Context context) {
super(context);
mContext = null;
}
public Window(final StandOutWindow context, final int id) {
super(context);
context.setTheme(context.getThemeStyle());
mContext = context;
mLayoutInflater = LayoutInflater.from(context);
...생략
// create the window contents
View content;
FrameLayout body;
...생략
addView(content);
body.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
// pass all touch events to the implementation
boolean consumed = false;
// handle move and bring to front
consumed = context.onTouchHandleMove(id, Window.this, v, event)
|| consumed;
// alert implementation
consumed = context.onTouchBody(id, Window.this, v, event)
|| consumed;
return consumed;
}
});
// attach the view corresponding to the id from the
// implementation
context.createAndAttachView(id, body);
사용자는 StandOutWindow를 상속받아 app 이름, view 구성, window 크기 설정등을 하면 간단한 window를 생성할 수 있으며 window의 세부 설정을 지정할 수 있도록 parameter를 풍부하게 제공하고 있음.
StandOutWindow example 중 SimpleWindow
: https://github.com/pingpongboss/StandOut/blob/master/example/src/wei/mark/example/SimpleWindow.java
public class SimpleWindow extends StandOutWindow {
@Override
public String getAppName() {
return "SimpleWindow";
}
@Override
public int getAppIcon() {
return android.R.drawable.ic_menu_close_clear_cancel;
}
@Override
public void createAndAttachView(int id, FrameLayout frame) {
// create a new layout from body.xml
LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.simple, frame, true);
}
// the window will be centered
@Override
public StandOutLayoutParams getParams(int id, Window window) {
return new StandOutLayoutParams(id, 250, 300,
StandOutLayoutParams.CENTER, StandOutLayoutParams.CENTER);
}
// move the window by dragging the view
@Override
public int getFlags(int id) {
return super.getFlags(id) | StandOutFlags.FLAG_BODY_MOVE_ENABLE
| StandOutFlags.FLAG_WINDOW_FOCUSABLE_DISABLE;
}
다만 각 window를 닫을 때 StandOut.close, StandOut.closeAll을 호출하면 되는대 각 window가 Android service로 돌아가고 있어 서비스까지 완전히 종료하려면 service의 intent filter 걸어서 stop시켜야 함.

floating window app을 만드는 방법에 대한 글과 간단한 prototype이다.
StandOut library 분석이 좀 부담된다면 이것을 참고하면 될듯.
