Dynimically load ListView. Refresh ListView after every n sec

Dynimically load ListView. Refresh ListView after every n sec - android

Below is my code that show an overlay with a list view that shows some information. I am updating the data after every 7 sec. I want to remove first list before displaying other.
In may case the ListViews are overlapping.
public class OverlayShowingService extends Service implements OnTouchListener, OnClickListener {

Issue is with Listview creation. Currnetly everytime AsynTask is created it is creating the new list view. just create your list view outside of asynctask and global to class so that you can access this listview object within asyncTask like below
private ListView listView;
initialige this listView in your relevant location like below.
listView = new ListView(getApplicationContext());
listView.setAlpha(0.0f);
listView.setBackgroundColor(0x55fe4444);
adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1, list);
listView.setAdapter(adapter);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, PixelFormat.TRANSLUCENT);
params.gravity = Gravity.LEFT | Gravity.TOP;
params.x = 0;
params.y = 0;
wm.addView(listView, params);
In your onPostExcute of your asyncTask update your adaper for any list data change like below
adapter.notifyDataSetChanged();

Why not working:
In 7.1 everything is working fine i get the call and the chathead apears.
In 4.4 [LG] I receive the call but nothing happens.
In 4.4 [BQ] Aplication crashes.
Any help?

Found the problem.
Where I'm calling startActivity from outside an activity like:
context.startActivity(new Intent(context, FloatingActivity.class)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));
in android 4.4 it is required to set the flag Intent.FLAG_ACTIVITY_NEW_TASK
o in all ocurrencies i need to call it like:
context.startActivity(new Intent(context, FloatingActivity.class)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));

Show a popup when user click on Overlay button

I have an Overlay Button in my Android app. I want to show a layout and interact with the views of my Layout when the user click on the button.

Send a broadcast when then the button is clicked and start activity from Broadcast receivers onReceive method.
Create a broadcast receiver,Register a Broadcast reciever onCreate() of your service then. Broadcast intent when the button is clicked. Finally the receiver will open a Activity(layout) when the overlay button is clicked.
If you only wanted to open a dialog this is a decent answer. https://stackoverflow.com/a/31221355/4179914
Turns out you can also theme a activity like a dialog as mentioned here
https://stackoverflow.com/a/7918720/4179914
public class OverlayClickReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent toDialog = new Intent(context, Main2Activity.class);
toDialog.setFlags(FLAG_ACTIVITY_NEW_TASK);
context.startActivity(toDialog);
}
}
Send Broadcast on overlay button clicked.
#Override
public void onClick(View v) {
broadcastClick();
}
private void broadcastClick() {
final Intent intent = new Intent("user.clicked.overlay.button");
final LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(this);
broadcastManager.sendBroadcast(intent);
}
Register Broadcast receiver onCreate()
#Override
public void onCreate() {
super.onCreate();
overlayShowing = new OverlayClickReceiver();
.......
}
private void registerClickReceiver() {
LocalBroadcastManager.getInstance(this).registerReceiver(overlayShowing,
new IntentFilter("user.clicked.overlay.button"));
}
Unregister Broadcast receiver onDestroy()
#Override
public void onDestroy() {
super.onDestroy();
..........
unregisterClickReceriver();
}
private void unregisterClickReceriver() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(overlayShowing);
}

From what i understood from the question, you want to get a view form xml files and add it to a window.
You can use View view = LayoutInflater.from(context).inflate(r.layout.overlay,null,false); and add that view with WindowManager.addView(view) to the window.

how i can create an overlay layout for quick launch?

i want change my overlayedButton (always on top) to overlayedLayout and in this layout put instlled app icon for lunch.
i do not want a widget layout. i want a layout like widget that every where is showing and always on top

Android close system overlay window(Started from service) when back button clicked

I have opened a window(displayed on top of other activities) on clicking floating view(similar to FB chat head), how to close window when device back button is pressed. Below is my service code
public class ServiceFloating extends Service {
public static int ID_NOTIFICATION = 2018;

params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 100;
windowManager.addView(chatHead, params);
try {
chatHead.setOnTouchListener(new View.OnTouchListener() {
private WindowManager.LayoutParams paramsF = params;
private int initialX;
private int initialY;
private float initialTouchX;
private float initialTouchY;
#Override public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
// Get current time in nano seconds.
long pressTime = System.currentTimeMillis();
// If double click...
if (pressTime - lastPressTime <= 300) {
createNotification();
ServiceFloating.this.stopSelf();

}
else { // If not double click....
mHasDoubleClicked = false;
}
lastPressTime = pressTime;
initialX = paramsF.x;
initialY = paramsF.y;
initialTouchX = event.getRawX();
initialTouchY = event.getRawY();
break;

break;
case MotionEvent.ACTION_MOVE:

paramsF.y = initialY + (int) (event.getRawY() - initialTouchY);
windowManager.updateViewLayout(chatHead, paramsF);
break;
}
return false;
}
});
} catch (Exception e) {
// TODO: handle exception
}
chatHead.setOnClickListener(new View.OnClickListener() {
#Override

showOptions(chatHead);
_enable = false;
// Intent intent = new Intent(getApplicationContext(), MainActivity.class);
// intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_SINGLE_TOP|Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);

}
});
}
public void showOptions(View anchor){

}
#Override
public void onTaskRemoved(Intent rootIntent) {
// TODO Auto-generated method stub
Intent restartService = new Intent(getApplicationContext(),
this.getClass());
restartService.setPackage(getPackageName());
PendingIntent restartServicePI = PendingIntent.getService(
getApplicationContext(), 1, restartService,
PendingIntent.FLAG_ONE_SHOT);
//Restart the service once it has been killed android
AlarmManager alarmService = (AlarmManager)getApplicationContext().getSystemService(Context.ALARM_SERVICE);
alarmService.set(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime() + 100, restartServicePI);
}
}
I couldn't add onBackPressed or a onKeyEvent methods inside the service. Please suggest a workaround. TIA

You should handle your view only from activity and use communication components such service binding or broadcasts. You shouldn't create views from service, its not appropriate.

Adding natural dragging effect to ImageView same as Facebook Messanger chat heads using Rebound library

I am developing one app where I am dragging around my ImageView in Activity.
I have configured Facebook Rebound library for spring animation which is originally used in Facebook Messenger's chat heads animations. I want to add this kind of animations to my ImageView when I drag it.
VIDEO
So far I am able to get spring animation when I touch ImageView (implemented spring on rootview), this is my code. How can I implement that natural type of dragging effect to my ImageView.
public class MainTry extends Activity {
int windowwidth;
int windowheight;
private LayoutParams layoutParams;
private final BaseSpringSystem mSpringSystem = SpringSystem.create();
private FrameLayout mRootView;
private Spring spring;
private View mImageView;
private VelocityTracker velocity = null;
private float dx;
private float dy;
private View rootView;
private ImageView img;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
// Create a system to run the physics loop for a set of springs.
SpringSystem springSystem = SpringSystem.create();
// Add a spring to the system.
spring = springSystem.createSpring();
rootView = getWindow().getDecorView()
.findViewById(android.R.id.content);
windowwidth = getWindowManager().getDefaultDisplay().getWidth();
windowheight = getWindowManager().getDefaultDisplay().getHeight();
img = (ImageView) findViewById(R.id.imageView2);
rootView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
// spring.setEndValue(1);
break;
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_CANCEL:
// spring.setEndValue(0);
break;
}
return true;
}
});
// Add a listener to observe the motion of the spring.
spring.addListener(new SimpleSpringListener() {
#Override
public void onSpringUpdate(Spring spring) {
// You can observe the updates in the spring
// state by asking its current value in onSpringUpdate.
float value = (float) spring.getCurrentValue();
float scale = .5f - (value * 0.1f);
img.setScaleX(scale);
img.setScaleY(scale);
}
});
// spring.setEndValue(1);
img.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
LayoutParams layoutParams = (LayoutParams) img
.getLayoutParams();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
dx = event.getRawX() - 10;
dy = event.getRawY() - 10;
if (velocity == null) {
// Retrieve a new VelocityTracker object to watch the
// velocity of a motion.
velocity = VelocityTracker.obtain();
} else {
// Reset the velocity tracker back to its initial state.
velocity.clear();
}
break;
case MotionEvent.ACTION_MOVE:
dx = event.getRawX() - 10;
dy = event.getRawY() - 10;
velocity.addMovement(event);
spring.setVelocity(velocity.getYVelocity());
spring.setCurrentValue(dy);
spring.setEndValue(dy);
layoutParams.leftMargin = (int) dx - 10;
layoutParams.topMargin = (int) dy - 10;
img.setLayoutParams(layoutParams);
break;
case MotionEvent.ACTION_CANCEL:
break;
case MotionEvent.ACTION_UP:
velocity.addMovement(event);
spring.setVelocity(velocity.getYVelocity());
spring.setCurrentValue(event.getRawY() - 10);
spring.setEndValue(0);
break;
default:
break;
}
return true;
}
});
}
#Override
public void onResume() {
super.onResume();
}
#Override
public void onPause() {
super.onPause();
}
}

what about this:
class V extends View implements SpringListener {
private static final int NUM_ELEMS = 4;
private Spring[] mXSprings = new Spring[NUM_ELEMS];
private Spring[] mYSprings = new Spring[NUM_ELEMS];
private Paint mPaint = new Paint();
private Bitmap mBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
public V(Context context) {
super(context);
SpringSystem ss = SpringSystem.create();
Spring s;
for (int i = 0; i < NUM_ELEMS; i++) {
s = ss.createSpring();
s.setSpringConfig(new MySpringConfig(200, i == 0? 8 : 15 + i * 2, i, true));
s.addListener(this);
mXSprings[i] = s;
s = ss.createSpring();
s.setSpringConfig(new MySpringConfig(200, i == 0? 8 : 15 + i * 2, i, false));
s.addListener(this);
mYSprings[i] = s;
}
}
#Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
mXSprings[0].setCurrentValue(w / 2);
mYSprings[0].setCurrentValue(0);
mXSprings[0].setEndValue(w / 2);
mYSprings[0].setEndValue(h / 2);
}
#Override
public void onSpringActivate(Spring s) {
}
#Override
public void onSpringAtRest(Spring s) {
}
#Override
public void onSpringEndStateChange(Spring s) {
}
#Override
public void onSpringUpdate(Spring s) {
MySpringConfig cfg = (MySpringConfig) s.getSpringConfig();
if (cfg.index < NUM_ELEMS - 1) {
Spring[] springs = cfg.horizontal? mXSprings : mYSprings;
springs[cfg.index + 1].setEndValue(s.getCurrentValue());
}
if (cfg.index == 0) {
invalidate();
}
}
#Override
public boolean onTouchEvent(MotionEvent event) {
mXSprings[0].setEndValue(event.getX());
mYSprings[0].setEndValue(event.getY());
return true;
}
#Override
protected void onDraw(Canvas canvas) {
for (int i = NUM_ELEMS - 1; i >= 0; i--) {
mPaint.setAlpha(i == 0? 255 : 192 - i * 128 / NUM_ELEMS);
canvas.drawBitmap(mBitmap,
(float) mXSprings[i].getCurrentValue() - mBitmap.getWidth() / 2,
(float) mYSprings[i].getCurrentValue() - mBitmap.getHeight() / 2,
mPaint);
}
}
class MySpringConfig extends SpringConfig {
int index;
boolean horizontal;
public MySpringConfig(double tension, double friction, int index, boolean horizontal) {
super(tension, friction);
this.index = index;
this.horizontal = horizontal;
}
}
}

i have used above V class directly in Window-manager and it's work perfectly and chatHead move like facebook messenger.
public class ChatHeadService extends Service
{
private LayoutInflater inflater;
private WindowManager windowManager;
private Point szWindow = new Point();
#Override
public void onCreate()
{
super.onCreate();
Log.v(Utils.LogTag, "Start Service");
}
private
void handleStart(){
windowManager = (WindowManager)getSystemService(WINDOW_SERVICE);
inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
if (Build . VERSION . SDK_INT >= Build . VERSION_CODES . HONEYCOMB) {
windowManager . getDefaultDisplay() . getSize(szWindow);
} else {
int w = windowManager . getDefaultDisplay() . getWidth();
int h = windowManager . getDefaultDisplay() . getHeight();
szWindow . set(w, h);
}
WindowManager . LayoutParams params = new WindowManager . LayoutParams(
WindowManager . LayoutParams . WRAP_CONTENT,
WindowManager . LayoutParams . WRAP_CONTENT,
WindowManager . LayoutParams . TYPE_PHONE,
WindowManager . LayoutParams . FLAG_NOT_FOCUSABLE |
WindowManager . LayoutParams . FLAG_WATCH_OUTSIDE_TOUCH |
WindowManager . LayoutParams . FLAG_LAYOUT_NO_LIMITS,
PixelFormat . TRANSLUCENT
);
params . gravity = Gravity . TOP | Gravity . LEFT;
params . x = 50;
params . y = 100;
V vImg = new V(this);
windowManager . addView(vImg, params);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent != null) {
if (startId == Service . START_STICKY) {
handleStart();
}
}
return super . onStartCommand(intent, flags, startId);
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy(){
super . onDestroy();
if (windowManager != null) {
// windowManager.removeView(chatHeadView);
}
}
}
