How to test the touch screen like this

I want to create an app to test the touch screen as shown in the above image.
My code for creating the layout as shown in the image is as follows :
private void fillScreen() {
try {
for (int i = 1; i < 14; i++) {
layoutMain = new LinearLayout(getApplicationContext());
for (int j = 1; j < 14; j++) {
b = new Button(getApplicationContext());
b.setTag("btn" + i + j);
b.setBackgroundColor(getResources().getColor(R.color.orange));
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
b.setBackgroundDrawable(getResources().getDrawable(R.drawable.my_button_bg));
} else {
b.setBackground(getResources().getDrawable(R.drawable.my_button_bg));
}
b.setOnTouchListener(getOnClickDoSomething(b));
b.setLayoutParams(param);
layoutMain.addView(b);
if (i == j || j == (15 - i - 1) || j == 13 || j == 1 || i == 1 || i == 13) {
b.setVisibility(View.VISIBLE);
}
else {
b.setVisibility(View.INVISIBLE);
}
}
layoutMain.setLayoutParams(layoutParams);
layoutButtons.addView(layoutMain);
}
} catch (Exception e) {
Log.e("promptMessage,RotationActivity Exception", e.toString());
}
}
View.OnTouchListener getOnClickDoSomething(final Button btn) {
return new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (!buttons.contains(btn.getTag())) {
buttons.add(btn.getTag());
btnCounter++;
}
btn.setBackgroundColor(getResources().getColor(R.color.videocon_header_green));
if ((btnCounter) == 67) {
flag++;
if (flag == 2)
promptMessage("Touch Screen test pass?");
}
return false;
}
};
}
I can change the colors of the button on touch but i want to "change the colors of the button when i swipe my fingers on the screen to left right top bottom".

How do I use .equals properly for this?

So here is my code,
public class GameView extends SurfaceView {
private SurfaceHolder holder;
private GameLoopThread gameLoopThread;
private List<Sprite> sprites = new ArrayList<Sprite>();
private long lastClick;
public int d = 0;
public int color;
TextView tv;
public int score;
public GameView(Context context) {
super(context);
gameLoopThread = new GameLoopThread(this);
holder = getHolder();
holder.addCallback(new Callback() {
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
createSprites();
gameLoopThread.setRunning(true);
gameLoopThread.start();
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format,
int arg2, int height) {
}
});
}
private void createSprites() {
int c = 10;
{
Random rnd = new Random();
color = Color.argb(255, rnd.nextInt(256), rnd.nextInt(256),
rnd.nextInt(256));
for (int b = 1; b <= c; b++) {
int random = (int) Math.ceil(Math.random() * 24);
if (random == 1) {
sprites.add(createSprite(R.drawable.bad1));
} else if (random == 2) {
sprites.add(createSprite(R.drawable.bad2));
} else if (random == 3) {
sprites.add(createSprite(R.drawable.bad3));
} else if (random == 4) {
sprites.add(createSprite(R.drawable.bad4));
} else if (random == 5) {
sprites.add(createSprite(R.drawable.bad5));
} else if (random == 6) {

} else if (random == 7) {
sprites.add(createSprite(R.drawable.bad7));
} else if (random == 8) {
sprites.add(createSprite(R.drawable.bad8));
} else if (random == 9) {
sprites.add(createSprite(R.drawable.bad9));
} else if (random == 10) {
sprites.add(createSprite(R.drawable.bad10));
} else if (random == 11) {
sprites.add(createSprite(R.drawable.bad11));
} else if (random == 12) {

What I am trying to do is get,

score = score + 5;
To check to see if somewhere in this code,
#Override
public boolean onTouchEvent(MotionEvent event) {
if (System.currentTimeMillis() - lastClick > 200) {
lastClick = System.currentTimeMillis();
synchronized (getHolder()) {
float x = event.getX();
float y = event.getY();
for (int i = sprites.size() - 1; i >= 0; i--) {
Sprite sprite = sprites.get(i);
Holds the value of one of the pics that are being deleted, but I am not sure how to code this properly. I am not sure if I need to place the pics into an array each time the randomizer runs or what but the code is taken from the "edu4java" tutorial from youtube.
I have the program on a loop as you can tell that I can delete the pics on touch and the score was right I just am not sure how to get the,
if ((sprites).equals(R.drawable.bad1))
score = score + 5;
To check to "see" the proper pic string. Do I need to check the array that the code "auto creates"? Is there a way to check and see what the value of a string is? Such as "seeing" what is actually being "held" by "sprite" or "sprites" ?

One problem is that you do not supply the source code for Sprite, but perhaps it looks like the code here? Given the code there, there is no neat solution to your problem with the class as it is.
So, how I would approach solving this problem is to add to each sprite a resource ID:
private Sprite createSprite(int resource) {
Bitmap bmp = BitmapFactory.decodeResource(getResources(), resource);
return new Sprite(this, bmp, resource);
}
Note that I add the extra resource parameter to the constructor. Furthermore, I would add to the Sprite class a method int Sprite.getResource(), so your collision detection code becomes:
if (sprite.isCollition(x, y))
{
if (sprite.getResource() == R.drawable.bad1)
score = score + 5;
else if (sprite.getResource() == R.drawable.bad2)
score = score + 5;
else ...
}
Note: this code is in no way optimal, but hopefully this will point you in the right direction to discover for yourself a better solution. Here in Stack Overflow we don't throw fishes, we teach people to fish.

You can't compare a bitmap with a resource Id, and actually trying to do it manually your self would end up in quiet exhaustive performance for a simple validation, what i would do and to keep it simple, i would create my own class that extends from Sprite, and in stead of passing the context and bitmap, i would pass the context and resource Id, then within this class i would decode the resource and keep a reference of the resource id, i would override the equal method from Sprites and use the reference used to create the object to do the comparison, this would be my class
public class MySprite extends Sprite{
private int bmpID;
public MySprite(Context context, int bmpID){
this.bmpID = bmpID;
Bitmap bmp = BitmapFactory.decodeResource(context.getResources(), bmpID);
super(context, bmp);
}
#Override
public boolean equals(Object o) {
if(!(o instanceof MySprite))return false;
return this.bmpID == MySprite.class.cast(o).getBmpId();
}
public int getBmpId(){
return bmpID;
}
}
This way i keep it as a simple int comparison, and most important you can use it to compare two objects of same bmpID, or something like what u wanted by doing this:
if ((sprites).getBmpId() == R.drawable.bad1))
score = score + 5;

TextView onTouchEvent within customview

I have a custom view, and within the custom view I create 4 text views. I want each of these text views to respond to on touch events. However, the textviews themselves do not respond to an on touch event. I can however, make an ontouch listener for the entire custom view. However, I do not want the whole view to have an ontouch event because I want the textviews that I have created to be dragged and dropped. I tried going the route of registering the x and y coordinates of the ontouch event and assuming that if the ontouch event is within the bounds of a textview, to change the coordinates of the textview, but that was overly complicated because if one textview got dragged to the coordinates of another one, then the ontouch event would "pick up" the other textview, so then I'd be moving two text views, which is not what I want. So, to sum it up, I want to know if it's possible to set in ontouch listener for a textview inside a customview, and if possible, why it is not working:
mScale.mPositive.get(0).setOnTouchListener(new OnTouchListener()
{
#Override
public boolean onTouch(View v, MotionEvent event)
{
mScale.mCurrentXPos[0] = event.getX();
mScale.mCurrentYPos[0] = event.getY();
mScale.mDrag = true;
return true;
}
});
This same code works for the custom view, but not for the specific textviews inside that customview.
Here is the custom view code:
public class Scale extends View
{
public Scale(Context context, AttributeSet attrs)
{
super(context, attrs);
mContext = this.getContext();
h = new Handler();
mCalendarDbHelper=new CalendarDbAdapter(mContext);
mCalendarDbHelper.open();
Cursor thoughts = mCalendarDbHelper.fetchThoughts();
//create a string array of negative thoughts from the db
while (thoughts.moveToNext())
{
if (thoughts.getString(thoughts.getColumnIndexOrThrow(CalendarDbAdapter.COLUMN_NAME_THOUGHT)).length() > 0 && thoughts.getString(thoughts.getColumnIndexOrThrow(CalendarDbAdapter.COLUMN_NAME_THOUGHT)).charAt(0) == '-')
{
negative_thoughts.add(thoughts.getString(thoughts.getColumnIndexOrThrow(CalendarDbAdapter.COLUMN_NAME_THOUGHT)));
}
}
thoughts.close();

The reason your TextView cannot receive touch events is that the TextView is drawn on the canvas just as a bitmap, not as a View. An excerpt from your code shown below illustrates this.
protected void onDraw(Canvas canvs)
{
....
negative = new TextView(mContext);
...
canvas.drawBitmap(negative.getDrawingCache(), ...)
To deliver touch events to your TextView, your Scale class should extend not View but ViewGroup and the TextView needs to be added as a subview to Scale class by using ViewGroup.addView() or addViewInLayout(). It is not a simple task to implement a ViewGroup subclass. You may have to implement onInterceptTouchEvent(MotionEvent) depending on your needs.
Android's source code will be of help.

Is your CustomView also sets some TouchListner??
If yes then this might causing issue..Remove TouchListner from CustomView and see if it works..

Character never stops from walking

I am creating a game which uses andendgine and here is my code:
Player stanley = new Player();
...
scene.registerUpdateHandler(new IUpdateHandler() {
public void onUpdate(float pSecondsElapsed) {
stanX = stanley.getX();
destX = x.getX();
if(destX < stanX){
if(hasMovedRight == 1){
stanley.stop();
hasMovedRight = 0;
}
else{
stanley.moveLeft();
hasMovedRight = 0
hasMovedLeft = 1;
}
}
if(destX > stanX){
if(hasMovedLeft == 1){
stanley.stop();
hasMovedLeft == 0;
}
else{
stanley.moveRight();
hasMovedLeft = 0;
hasMovedRight = 1;
}
}
}
}
what i want is to stop Player from walking whenever his position X is equal to the touched area X. The problem is it never stop from walking. Thanks!

Your if statements are missing an element where destX == stanX. and you should really use else if. See modified code below.
if(destX + 8 < stanX){
if(hasMovedRight == 1){
stanley.stop();
hasMovedRight = 0;
}
else{
stanley.moveLeft();
hasMovedRight = 0
hasMovedLeft = 1;
}
}
else if(destX - 8 > stanX){
if(hasMovedLeft == 1){
stanley.stop();
hasMovedLeft == 0;
}
else{
stanley.moveRight();
hasMovedLeft = 0;
hasMovedRight = 1;
}
}
else //makes stanley stop. (calls stop method), if at touched x.
{
stanley.stop();
hasMovedRight = 0;
hasMovedLeft = 0;
}

try this one
setOnSceneTouchListener(new IOnSceneTouchListener() {
#Override
public boolean onSceneTouchEvent(Scene scene, TouchEvent event) {
int touchX = (int) (event.getX() - (sCHARStanley.getWidth() / 2));
//so that your sprite will go to the touched part of the screen
}

SoftKeyboard for android

I am creating softkeyboard for android 2.2 and higher. everything is fine but when i type really quick then some time my ACTION_DOWN method is not calling. Actual flow of called method should look like
1) motionEvent.ACTION_DOWN
2) OnPress()
3) motionEvent.ACTION_UP
4) OnRelease() and repeat same order for next word.
if i type at normal speed then it works fine but if i type fast then above order of method execution looks like
1) motionEvent.ACTION_DOWN
2) OnPress()
3) OnRelease()
4) motionEvent.ACTION_UP and for next word OnPress and OnRelease() methods are being called.
any suggestions?
Edit
My LatinKeyboardView class that contains MotionActionEvents

This is a very long onTouchEvent handler, I suggest breaking it up into more logical steps. I also have had the issue of seemingly "out-of-order" events when trying to handle the touchscreen.
I found that I wasn't handling the events per pointer ID correctly. I'd check to make sure you are handling multiple pointers as expected. The device I test with (N1) only supports two pointers, but others support many more, and those should be accounted for.
For handling touchscreen "soft-buttons" as an onTouchEvent event, I've found it useful to create a state machine class. Use the MotionEvent parameters as input events to the state machine, and cause state transitions to trigger your wanted events. An explicit, state-driven approach will give you the expected results you are looking for.
