Define the starting point in android?

This app translates form specific graffiti shapes to text.
I have 3 categories, letters, numbers and other characters.
The starting point defines the category to choose the output from. It works will on the emulator but with changing phones (resolution) it starts to get wrong.
This is my activity for drawing the graffiti and the TextView that show the result.
This is the activity XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

This is how I choose the category for now i the java file:
private List<Point> input; // a list contains the drawn graffiti shape coordinates
private Input inserted; // instance of a class
String section; // the category from which we receive the output
boolean proceed ; // if the starting point in the allowed range
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public boolean onTouchEvent(MotionEvent touchEvent)
{
super.onTouchEvent(touchEvent);
switch(touchEvent.getAction())
{
case MotionEvent.ACTION_DOWN:
{
input = new ArrayList<>();
if(touchEvent.getY() < 1216)
{
proceed = false;
}
else if(touchEvent.getY() > 1465)
{
proceed = true;
section = "letter";
}
else if(touchEvent.getX() < 506)
{
proceed = true;
section = "char";
}
else
{
proceed = true;
section = "number";
}
//Inserting the touch event points into the array list of points
for (int h = 0; h < touchEvent.getHistorySize(); h++)
{
for (int p = 0; p < touchEvent.getPointerCount(); p++)
{
float x = touchEvent.getHistoricalX(p,h);
float y = touchEvent.getHistoricalY(p,h);
input.add(new Point(x,y));
}
}
break;
}
case MotionEvent.ACTION_MOVE:
{
//Inserting the touch event points into the array list of points
for (int h = 0; h < touchEvent.getHistorySize(); h++)
{
for (int p = 0; p < touchEvent.getPointerCount(); p++)
{
float x = touchEvent.getHistoricalX(p,h);
float y = touchEvent.getHistoricalY(p,h);
input.add(new Point(x,y));
}
}
break;
}
case MotionEvent.ACTION_UP:
{
//Inserting the touch event points into the array list of points
for (int h = 0; h < touchEvent.getHistorySize(); h++)
{
for (int p = 0; p < touchEvent.getPointerCount(); p++)
{
float x = touchEvent.getHistoricalX(p,h);
float y = touchEvent.getHistoricalY(p,h);
input.add(new Point(x,y));
}
}
if(proceed)
{
inserted = new Input();
String letter =inserted.checkPoint(input,section);
if(letter.equals(""))
{
Toast.makeText(this,"No Such Graffiti, check the our dictionary!",Toast.LENGTH_SHORT).show();
}
TextView myText =(TextView) findViewById(R.id.res);
String text = myText.getText().toString();
myText.setText(text+letter);
}
break;
}
}
return true;
}

it looks to me that you're trying to get the touchEvents from the topmost view and according to the coordinates determine which child is touched? If so this is very wrong. The way to go is to register for the children themselves the onClick or onTouch listener and just check the view's id in there to determine which one was touched.
Edit:
The easiest way to do this is to add this to all three RelativeLayouts that you gave an id:
android:onClick="myMethod"
And then add this in your activity
public void myMethod(View view) {
switch(view.getId()) {
case R.id.letters:
//do here what you wanna do with letters
break;
case R.id.chars:
//do here what you wanna do with chars
break;
case R.id.numbers:
//do here what you wanna do with numbers
break;
}
}
you can of course rename the method as you like as long as it is the same as you specified in the xml

Error in property animation

I'm creating a small application for practice some in Android programming. It's a kind of puzzle game like this:
Screen from application
I have a following issue: when I slide a button left or right in x property all is OK. I can move each button frequently left and right. The problem begins when I move the button down or up in y property. I can only move the button once and next it will be no longer available for the onTouchListener. It become immobile in any direction and any action isn't performed. Here is my java activity file and the layout xml.

I have really no idea what cause this problem. Please give me a small prompt on what may cause this issue. Thanks in advance

You should return true if the listener has consumed the event. Otherwise, it should return false as default.
View.OnTouchListener mTouchListener = new View.OnTouchListener() {
...
return false;
}

I changed my code following your tip :
View.OnTouchListener mTouchListener = new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event){
float x1=0, x2, y1=0, y2, dx, dy;
switch(event.getActionMasked()) {
case(MotionEvent.ACTION_DOWN):
x1 = event.getX();
y1 = event.getY();
break;
case(MotionEvent.ACTION_UP): {
x2 = event.getX();
y2 = event.getY();
dx = x2-x1;
dy = y2-y1;
if(Math.abs(dx) > Math.abs(dy)) {
if(dx>0){
v.animate().xBy(DX);
}
else{
v.animate().xBy(-DX);
}
} else {
if(dy>0){
v.animate().yBy(DY);
}
else{
v.animate().yBy(-DY);
}
}
return true;
}
}
return false;
}
};
Unfortunately, that doesn't solve my problem. Please, correct me if I made a mistake

Get button coordinates and detect if finger is over them - Android

I have 4 buttons in my android app activity. This is what it looks like:
As you can see, the textViews at the bottom of the screen display the x and y coordinates. The coordinates are in reference to a relative layout. (See below given code)
Now, what I want to do is get the x and y coordinates of the 4 buttons at runtime and then figure out if my finger is touching the buttons while moving or not. In simple words, I want to press the buttons by swiping my finger over them instead of lifting and touching. How can I achieve it? I want to implement it in my piano application.
I was able to get the coordinates on screen and they change as I move my finger.
So, my question is How can I get the coordinates of the buttons and detect if my finger is swiping above them?:

getX() getY() for a OnTouchListener give coordinates relative the the cooresponding view.
If you prefer screen coordinates instead you can use one of the following
overwrite onTouchEvent for the activity and remove OnTouchListener-s for buttons,
in which case MotionEvent will report screen coordinates instead of Button coordinates
#Override
public boolean onTouchEvent (MotionEvent event) {
xcordview.setText(String.valueOf(event.getX()));
ycordview.setText(String.valueOf(event.getY()));
return true;
}
use getTop() getLeft() in OnTouchListener for a button:
touchview.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
xcordview.setText(String.valueOf(event.getX()+v.getLeft()));
ycordview.setText(String.valueOf(event.getY()+v.getTop()));
return true;
}
});
You may consider using GestureDetector to detect swipes, however it isn't really necessary.

karioki 's solution works well. In order to make it work even when we start the move from inside one of the buttons, just add
android:clickable="false"
for every button in xml.

How to scroll an image horizontally?

I have a problem with horizontal scroll view.
This is my XML code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/relative_layout_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bg"
tools:context=".MainActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/home_title_id"
android:text="#string/home_title"
android:layout_marginTop="#dimen/forty_text_size"
android:textColor="#android:color/white"
android:layout_centerHorizontal="true"
android:gravity="center"
android:textSize="#dimen/forty_text_size" />
<LinearLayout
android:id="#+id/linear_layout_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/home_title_id">
<HorizontalScrollView
android:id="#+id/horizontal_view_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/home_image_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/abc" />
</HorizontalScrollView>
</LinearLayout>
</RelativeLayout>
In my Java class, extending activity I have declared all the widgets, then i created a class scrollview, extending horizontal scroll view.
The Java code is as follows:
class scrollview extends HorizontalScrollView
{
private static final int SWIPE_MIN_DISTANCE = 5;
private static final int SWIPE_THRESHOLD_VELOCITY = 300;
private ArrayList mItems = null;
private GestureDetector mGestureDetector;
private int mActiveFeature = 0;
public scrollview(Context context)
{
super(context);
}
public void setFeatureItems(ArrayList items)
{
LinearLayout internalWrapper = new LinearLayout(getContext());
internalWrapper.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
internalWrapper.setOrientation(LinearLayout.HORIZONTAL);
addView(internalWrapper);
this.mItems = items;
for(int i = 0; i< items.size();i++)
{
LinearLayout featureLayout = (LinearLayout) View.inflate(this.getContext(),R.layout.activity_main,null);
//...
//Create the view for each screen in the scroll view
//...
internalWrapper.addView(featureLayout);
}
setOnTouchListener(new View.OnTouchListener()
{
#Override
public boolean onTouch(View v, MotionEvent event)
{
//If the user swipes
if (mGestureDetector.onTouchEvent(event))
{
return true;
}
else if(event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL )
{
int scrollX = getScrollX();
int featureWidth = v.getMeasuredWidth();
mActiveFeature = ((scrollX + (featureWidth/2))/featureWidth);
int scrollTo = mActiveFeature*featureWidth;
smoothScrollTo(scrollTo, 0);
return true;
}
else
{
return false;
}
}
});
mGestureDetector = new GestureDetector(new MyGestureDetector());
}
class MyGestureDetector extends SimpleOnGestureListener
{
#Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)
{
try
{
//right to left
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY)
{
int featureWidth = getMeasuredWidth();
mActiveFeature = (mActiveFeature < (mItems.size() - 1))? mActiveFeature + 1:mItems.size() -1;
smoothScrollTo(mActiveFeature*featureWidth, 0);
return true;
}
//left to right
else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY)
{
int featureWidth = getMeasuredWidth();
mActiveFeature = (mActiveFeature > 0)? mActiveFeature - 1:0;
smoothScrollTo(mActiveFeature*featureWidth, 0);
return true;
}
} catch (Exception e) {
Log.e("Fling", "There was an error processing the Fling event:" + e.getMessage());
}
return false;
}
}
}
But nothing happens, please help.
ORWILL IT BE BETTER TO HAVE THE SCROLL CLASS IN THE ONTOUCH LISTNER FUNCTION???

Wrong tag placement in your layout.xml file i think. Place LinearLayout having ImageView in HorizontalScrollView instead of HorizontalScrollView in LinearLayout as below:
<HorizontalScrollView
android:id="#+id/horizontal_view_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/home_title_id" >
<LinearLayout
android:id="#+id/linear_layout_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/home_image_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/abc" />
</LinearLayout>
</HorizontalScrollView>

there is no need for java coding here. this java coding is required only for SWIPE functionality
the XML coding alone is enough!!!but, in the following format
<HorizontalScrollView
android:id="#+id/horizontal_view_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/home_title_id" >
<LinearLayout
android:id="#+id/linear_layout_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/home_image_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/abc" />
</LinearLayout>
</HorizontalScrollView>
as horizontal scroll can hold only one child node.

Values of Buttons Not Updating Properly

I have an integer ArrayList and several buttons. Each button corresponds to an index of the ArrayList and I want to display the value of each button's corresponding index as its text. I have everything working with button behavior, etc. The problem is when I go to swap a button's value (index value) with another it will start to display 0s for every value I swap it with. I am always going to be swapping the 0 with something else.
So if I have buttons: b1, b2, b3 with values 0, 1, 2 respectively and I swap the values of b1 and b2. The result becomes 0, 0, 2. This is the swapping function:
public static void swap(ArrayList<Integer> list, int firstInd, int secondInd) {
int temp = list.get(firstInd);
list.set(firstInd, list.get(secondInd));
list.set(secondInd, temp);
}
This swap method works, I have tested it independently using print statements, etc. and there are no duplicate 0s and all of the rest of the numbers remain in the list.
Here is the relevant code:
// class declaration
static ArrayList<Integer> numList = new ArrayList<Integer>();
// onCreate
// initialize ArrayList
// displays initial values on buttons
#Override
public void onClick(View v) {
switch(v.getId()) {
case R.id.first: {
switchButtonValues(R.id.first);
b1.setText(String.valueOf(numList.get(0)));
updateButtonStates();
break;
}
case R.id.second: {
switchButtonValues(R.id.second);
b2.setText(String.valueOf(numList.get(1)));
updateButtonStates();
break;
}
// etc for all buttons
public static void switchButtonValues(int buttonNum) {
switch(buttonNum) {
case R.id.first: {
if(numList.get(1) == 0) {
swap(numList, 0, 1);
} else if (numList.get(3) == 0) {
swap(numList, 0, 3);
} else {
}
break;
}
case R.id.second: {
// etc. for the buttons
The buttons displaying the initial values is correct. So I know the ArrayList is getting initialized properly. The problem occurs when the swapping occurs. All of the values are getting overwritten with 0 somehow.
Even though 0s are overwriting the other values, the button behavior is working correctly because it knows where the "real" 0 is. I have cleaned the project too.
Why is this happening? Anyone have any ideas?

I did an example, I hope it's near what you expect:

public static void swap(ArrayList<Integer> list, int firstInd, int secondInd) {
int temp = list.get(firstInd);
list.set(firstInd, list.get(secondInd));
list.set(secondInd, temp);
}

that's worked just fine, and really quite a funny when you shuffle the places and try to put then in order... hehehe
It's simple and was one good idea for a game :D (I will do some sort of this genre and let see what happens)
I think that's possible to better the code, I had suspect of this part of your code:
case R.id.btn_01: {
switchButtonValues(R.id.btn_01);
btn_01.setText(String.valueOf(numList.get(0)));
updateButtonStates();
break;
}
I thinked you switch the values, and next set the text with the numList value of that position, but, you had changed with the 0, isn't? Maybe it's your problem, try put the line that set the text before the switch...
cya,
