Android Animations and functions need to move to activity?

I am working on a small game with touch-motion, bluetooth, and menus. At the moment the code is implemented is in my custom View.
For example vectors of classes that store game-data, vectors for current data and later will there be some threads for animations and timers.
Yet there is no icons for "abilities", but I will implement them too.
Later will there be a process or a service with bluetooth which also calls methods which are at the moment in the custom view class.
I suppose this is a bad design - so I have no concrete idea how I can or should move my functions to for example the activity which holds the custom view and how to let the custom view and activity communicate with each other.
Maybe some of you have advice on what to do.
Here is the activity:
Gamecontroller_Activity:
public class Gamecontroller_Activity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i("Enter Function","Enter onCreate Gamecontroler_Activity");
setContentView(R.layout.activity_gamecontroller);
}
}
activity_gamecontroller.xml:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.example.calma.Gamecontroller_View
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>

Project:

Make those changes:
1) in your activity_gamecontroller.xml:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.example.calma.Gamecontroller_View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/myGameController"/>
</RelativeLayout>
2) in your Gamecontroller_Activity:
public class Gamecontroller_Activity extends Activity {
Gamecontroller_View mGameControllerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i("Enter Function","Enter onCreate Gamecontroler_Activity");
setContentView(R.layout.activity_gamecontroller);
mGameControllerView = (Gamecontroller_View) findViewById(R.id.myGameController);
}
}
3) now you can call for example mGameControllerView.initPlayerMe(); from any method in your Gamecontroller_Activity .
This is an example:
public class Gamecontroller_Activity extends Activity {
Gamecontroller_View mGameControllerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i("Enter Function","Enter onCreate Gamecontroler_Activity");
setContentView(R.layout.activity_gamecontroller);
mGameControllerView = (Gamecontroller_View) findViewById(R.id.myGameController);
testMethod();
}
private void testMethod(){
mGameControllerView.enemySpawn();
}
}

Avoid a View Class to update on pressing a button

I have a bitmap, which is drawn in my Sprite class, this bitmap is more than one picture in one, so I can animate it.
When I inflate the GameLayout next to my XML, this sprite is drawn. Every time the run() method of my GameActivity is called (with special circumstances) this picture updates itself 4 times, so the animation is through.
This is all running perfectly, but my Problem is, that if I press the button (no matter if the curcumstances are fulfilled), the bitmap jumps to the next picture, so, the bitmap updates itself, without me calling it with view.invalidate().
Do you have any idea how I could stop this?

onDraw of View Class:
#Override

{
sprite.draw(canvas);
sprite.update(System.currentTimeMillis());
}
The Sprite Class:
public class Sprite
{
//private static final String TAG = Sprite.class.getSimpleName();
private Bitmap bitmap; // the animation sequence
private Rect sourceRect; // the rectangle to be drawn from the animation bitmap
private int frameNr; // number of frames in animation
private int currentFrame; // the current frame
private long frameTicker; // the time of the last frame update
private int framePeriod; // milliseconds between each frame (1000/fps)
private int spriteWidth; // the width of the sprite to calculate the cut out rectangle
private int spriteHeight; // the height of the sprite
private int x; // the X coordinate of the object (top left of the image)
private int y; // the Y coordinate of the object (top left of the image)
public Sprite(Bitmap bitmap, int x, int y, int width, int height, int fps, int frameCount)
{
this.bitmap = bitmap;
this.x = x;
this.y = y;
currentFrame = 0;
frameNr = frameCount;
spriteWidth = bitmap.getWidth() / frameCount;
spriteHeight = bitmap.getHeight();
sourceRect = new Rect( 0, 0, spriteWidth, spriteHeight);
framePeriod = 1000 / fps;
frameTicker = 0l;
}
public void update(long gameTime)
{
if (gameTime > frameTicker + framePeriod)
{
frameTicker = gameTime;
// increment the frame
currentFrame++;
if (currentFrame >= frameNr)
{
currentFrame = 0;
}
}
// define the rectangle to cut out sprite
this.sourceRect.left = currentFrame * spriteWidth;
this.sourceRect.right = this.sourceRect.left + spriteWidth;
}
public void draw(Canvas canvas)
{
// where to draw the sprite
Rect destRect = new Rect( x, y, x + spriteWidth, y + spriteHeight);
canvas.drawBitmap(bitmap, sourceRect, destRect, null);
}
}

The solution for this was pretty easy:
Instead of using view.invalidate() in my run() method I used
((GameLayout) view).update(System.currentTimeMillis()) so I call the update() isntead of the onDraw() of my GameLayout class.
With this change I could delete the update() method out of my onDraw() so if onDraw() is getting updated the picture will update, but will not change.
Then I added invalidate() to my update() method so it would redraw itself after updating.
Now everything is running smooooooothly.

How to make listview empty in android

I am using pulltorefresh in my application.In onRefresh(), I tried to remove all the items by keeping listView.setAdapter(null);
But still my listView.getCount() is returning 1.
listView.setOnRefreshListener(new OnRefreshListener() {
// #Override
public void onRefresh() {
// Your code to refresh the list contents goes here
scroll=true;
pic.clear();
id.clear();
name.clear();
msg.clear();
img.clear();
profimg.clear();
objid.clear();
comment.clear();
weburl.clear();
adapter.clear();
likes.clear();
like_or_unlike.clear();
previousTotal = 0;
adapter.clear();
j=0;
loading = true;
webserv="https://graph.facebook.com/me/home?access_token="+accesstoken;
// listView.setAdapter(null);
System.out.println(listView.getCount());
// doInBack dob=new doInBack();
// dob.execute();
System.out.println(listView.getCount());
doback(webserv);
Log.e("hi","doback called");
}
});

I really didnt understand why it is returning 1 instead of 0.

Have you tried to clear the list and the notify the adapter?
I mean, If I use an String array to make the list:
ArrayList<String> names=new ArrayList<String>();
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, names);
ListView listView = (ListView) findViewById(android.R.id.list);
listView.setAdapter(adapter);
If I want to clear it, I make:
names.clear();
adapter.notifyDataSetChanged();

Quick dialog using onclick search view in android

I am looking for a QuickAction dialog using onclick search view. Here is image showing what I am looking for:

Does anybody have a sample or link showing how to achieve this?
Also, how can I break the Quick action dialog in two parts? Currently it is shown like this:
