OnTouchEvent doesn't work in RelatiVeLayout

OnTouchEvent doesn't work in RelatiVeLayout - android

This is my layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/relativeLayoutHelper"

android:focusable="true"
android:clickable="true">

android:focusableInTouchMode="true"

android:focusable="true">
</LinearLayout>
</RelativeLayout>
In programm i add object ScreenPager in LinearLayout, it extends class ViewPager, and I add another LinearLayout with TextViews:
public class ModuleHelpOfGuide extends Activity {
private final String PATH_IMAGE = "helper";
float x1,y1, x2,y2;
ScreenPager screenPagerHelper;
LinearLayout linearLayoutHelper,linearLayoutHorizontalHelper;
RelativeLayout relativeLayoutHelper;
TextView pageTextView [];
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.screen_pager_layout);
LayoutInflater.from(this).setFactory(ScreenPager.getShortNameFactory());
screenPagerHelper = new ScreenPager(this);
addInScreen();
relativeLayoutHelper = (RelativeLayout)findViewById(R.id.relativeLayoutHelper);
linearLayoutHelper = (LinearLayout) findViewById(R.id.LinearForPager);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
screenPagerHelper.setLayoutParams(layoutParams);
linearLayoutHelper.addView(screenPagerHelper);
relativeLayoutHelper.setOnTouchListener(touchListenerRelativeHelper);

String [] listAssets;
try {

int count = listAssets.length;
pageTextView = new TextView [count];
for (int i = 0; i < count; i++) {
pageTextView[i] = createTexViewHelper();
pageTextView[i].setLayoutParams(layoutParamsPageText);
linearLayoutHorizontalHelper.addView(pageTextView[i]);
}
pageTextView[screenPagerHelper.getCurrentItem()].setTextColor(Color.WHITE);
} catch (IOException e) {
e.printStackTrace();

Drawable drawable = Drawable.createFromStream(file,null);

imageView.setLayoutParams(layoutParams);
imageView.setImageDrawable(drawable);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
screenPagerHelper.addScreen(imageView);
}
}
}catch (IOException e) {

}
}
private TextView createTexViewHelper (){

textViewHelper.setText(".");
textViewHelper.setTextSize(65);

textViewHelper.setTextColor(android.graphics.Color.GRAY);
return textViewHelper;
};
View.OnTouchListener touchListenerRelativeHelper = new View.OnTouchListener(){
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN){
int current = screenPagerHelper.getCurrentItem();
for (int i = 0; i < pageTextView.length; i++){
pageTextView[i].setTextColor(android.graphics.Color.GRAY);
}
pageTextView[current].setTextColor(getResources().getColor(R.color.white));
return true;
}
if (event.getAction() == MotionEvent.ACTION_UP){
int current = screenPagerHelper.getCurrentItem();
for (int i = 0; i < pageTextView.length; i++){
pageTextView[i].setTextColor(android.graphics.Color.GRAY);
}
pageTextView[current].setTextColor(getResources().getColor(R.color.white));
return false;
}
return true;
}
};
}
Problem in TouchEvent, it's not working if use on Relative or Linear Layots, if i use it on ScreenPager than event begin work, but textView lag on 1 image in slaider. If i use TouchEvent in ScreenPager and return true, than slider doesnt work. How track event touchlistener on RelativeLayout?

I solved problem not good, but it works, how could, set on ScreenPager listener TouchListener and in touchlistener:
View.OnTouchListener touchListenerHelper = new View.OnTouchListener(){
#Override
public boolean onTouch(View v, MotionEvent event) {
int current;
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
x1 = event.getX();
break;
case MotionEvent.ACTION_UP:
x2 = event.getX();
if (x1 > x2 ) {
current = screenPagerHelper.getCurrentItem()+1;
current = current == pageTextView.length ? pageTextView.length - 1 : current;
for (int i = 0; i < pageTextView.length; i++) {
pageTextView[i].setTextColor(android.graphics.Color.GRAY);
}
pageTextView[current].setTextColor(getResources().getColor(R.color.white));
} else if ( x1 < x2){
current = screenPagerHelper.getCurrentItem()-1;
current = current < 0 ? 0 : current;
for (int i = 0; i < pageTextView.length; i++) {
pageTextView[i].setTextColor(android.graphics.Color.GRAY);
}
pageTextView[current].setTextColor(getResources().getColor(R.color.white));
}
break;
}
return false;
}
};
becouse event of ViewPAger begin after my costume event, i add to current 1.

I made Drag and Drop to Move Objects on Finger Touch in Android
Reference site this : http://grishma102.blogspot.kr/2013/10/drag-and-drop-functionality-to-move.html
But, my activity's zoom in, zoom out don't function
When I move objects on Finger Touch, the objects just zoom out and screen out.
please help me..

Try overriding OnDrag() listener instead of onTouch()
view.setOnDragListener(new View.OnDragListener() {
#Override
public boolean onDrag(View view, DragEvent dragEvent) {
return true;
}
});

Adding multiple image views programmatically

I'm basically trying to achieve drag&drop feature..
What i'm trying is that i provides sequence of images on the screen, if i click on any image available in images row that will be added to the Mains screen. But i'm getting problem that when i add new view into the Main Screen then all the other views also moved to top left corner.
Can you please tell me what is the problem...? Or kindly suggest me a tutorial or link where i can find solution.... or how to achieve this ?
I'm using Framelayout, So that i also achieve images overlapping...
This is the class in which all code is working:
public class drag extends Activity implements OnClickListener, OnTouchListener
{
ImageView img1;
Button btn,btn2;
FrameLayout layout;
LayoutParams params;
ImageView im , im2, im3 ,im4;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
layout = (FrameLayout) findViewById(R.id.vg);
layout.setDrawingCacheEnabled(true);
im = (ImageView)findViewById(R.id.img1);
im.setDrawingCacheEnabled(true);
im.setOnTouchListener(this);
im.setOnClickListener(this);
btn = (Button)findViewById(R.id.btn1);
btn.setDrawingCacheEnabled(true);
btn.setOnClickListener(this);
btn.setOnTouchListener(this);
btn2 = (Button)findViewById(R.id.btn2);
btn2.setDrawingCacheEnabled(true);
btn2.setOnClickListener(this);
btn2.setOnTouchListener(this);
params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
btn.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
im2 = new ImageView(drag.this);
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image);
im2.setImageBitmap(bm);
im2.setOnTouchListener(drag.this);
im2.setOnClickListener(drag.this);
layout.addView(im2, params);
}
});
btn2.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image);
saveImage(bm);
}
});
}
public void saveImage(Bitmap myBitmap)
{
MediaStore.Images.Media.insertImage(getContentResolver(), myBitmap, "mmsImage" , "mmsimage");
}
int l, t, r, b;
int oldLeft, oldTop;
PointF p, curr;
#Override
public boolean onTouch(View view, MotionEvent me)
{
if (me.getAction() == MotionEvent.ACTION_DOWN)
{
//status = START_DRAGGING;
Log.i("status"," AAA dOWN");
img1 = new ImageView(this);
view.setDrawingCacheEnabled(true);
Bitmap mmsImage = Bitmap.createBitmap(view.getDrawingCache());
img1.setImageBitmap(mmsImage);
img1.setOnTouchListener(drag.this);
img1.setOnClickListener(drag.this);
oldLeft = (int)view.getLeft();
oldTop = (int)view.getTop();
p = new PointF(me.getRawX(), me.getRawY());
}
if (me.getAction() == MotionEvent.ACTION_MOVE)
{
Log.i("status"," AAA draging");
int xDiff = (int)(me.getRawX() - p.x);
int yDiff = (int)(me.getRawY() - p.y);
p.x = me.getRawX();
p.y = me.getRawY();
l = view.getLeft();
t = view.getTop();
r = view.getRight();
b = view.getBottom();
view.layout(l + xDiff, t + yDiff , r + xDiff, b + yDiff);
}
if (me.getAction() == MotionEvent.ACTION_UP)
{
Log.i("status"," AAA UP");
//captureUserMove(view);
}
return false;
}
}
Here is the XML :
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/vg"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white" >
<ImageView
android:id="#+id/img1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#drawable/ic_launcher" />
<Button
android:id="#+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<Button
android:id="#+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</FrameLayout>

You set params, but don't specify how to position the added view. Try this:
In onCreate()
params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.LEFT | Gravity.TOP; // you need this for margins to work
In the click listener:
// your x and y where you want the new view
params.leftMargin = x;
params.topMargin = y;

Putting
params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
inside
#Override
public void onClick(View v)
{
}
will work.

What type of event listener should i use in android?

I have a 5x5 grid (I ve drawn a matrix in canvas). I ve arranged the textviews in the the grid
in the order of a array..ie (5X5 ) array. The thing is I want to change the values on of the text view when I swipe horizontally or vertically.
Say suppose I am using a touch movement on the screen continuously from [4][0] to [4][2] I want to modify the values of the textviews in those places.
Any ideas?

This piece of code might help you:
public class MyClass extends Activity implements OnGestureListener{
ArrayList<TextView> tvs = new ArrayList<TextView>();
public void onCreate(Bundle b) {
super.onCreate(b);
setContentView(R.layout.mygrid);
}
public void onResume() {
super.onResume();
GestureOverlayView gd = (GestureOverlayView)findViewById(R.id.gd);
LinearLayout g = (LinearLayout)findViewById(R.id.mygrid);
gd.addOnGestureListener(this);
g.setOrientation(LinearLayout.VERTICAL);
for (int i = 0; i < 5; i++) {
LinearLayout row = new LinearLayout(this);
g.addView(row);
row.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout.LayoutParams rowlp = (LayoutParams) row.getLayoutParams();
rowlp.width = LayoutParams.MATCH_PARENT;
rowlp.weight = 1;
rowlp.height = LayoutParams.WRAP_CONTENT;
row.setLayoutParams(rowlp);
for (int j = 0; j < 5; j++) {
TextView tv = new TextView(this);
row.addView(tv);
LinearLayout.LayoutParams lp = (LayoutParams) tv.getLayoutParams();
lp.height = LayoutParams.MATCH_PARENT;
lp.width = 0;
lp.weight = 1;
tv.setLayoutParams(lp);
tv.setText(String.valueOf(i * 5 + j));
tv.setTag(String.valueOf(i * 5 + j));
tv.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL);
tvs.add(tv);
if ((i * 5 + j) % 2 == 0)
tv.setBackgroundColor(0xff888888);
}
}
}
private boolean isPointInsideView(float x, float y, View view){
int location[] = new int[2];
view.getLocationOnScreen(location);
int viewX = location[0];
int viewY = location[1];
//point is inside view bounds
if(( x > viewX && x < (viewX + view.getWidth())) &&
( y > viewY && y < (viewY + view.getHeight()))){
return true;
} else {
return false;
}
}
#Override
public void onGesture(GestureOverlayView overlay, MotionEvent event) {
float x = event.getRawX();
float y = event.getRawY();
for (TextView v : tvs) {
if (isPointInsideView(x, y, v)) {
v.setText("HERE");
}
}
}
#Override
public void onGestureCancelled(GestureOverlayView overlay, MotionEvent event) {
}
#Override
public void onGestureEnded(GestureOverlayView overlay, MotionEvent event) {
}
#Override
public void onGestureStarted(GestureOverlayView overlay, MotionEvent event) {
}
}
XML:
<?xml version="1.0" encoding="utf-8"?>
<android.gesture.GestureOverlayView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/gd"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/mygrid"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.gesture.GestureOverlayView>
Hope it helps.
Edit2: replace the methods above with these for highly increased performance:
private TextView getAbove(float x, float y) {
for (int i = 0; i < 5; i++)
for (int j = 0; j < 5; j++)
if (isPointInsideView(x, y, tvs[i][j]))
return tvs[i][j];
return null;
}
#Override
public void onGesture(GestureOverlayView overlay, MotionEvent event) {
float x = event.getRawX();
float y = event.getRawY();
if (last == null || !isPointInsideView(x, y, last)) {
last = getAbove(x,y);
draw();
}
}
private void draw() {
if (last == null)
return;
last.setText("+");
}
private void reset() {
last = null;
for (int i = 0; i < 5; i++)
for (int j = 0; j < 5; j++)
tvs[i][j].setText(String.valueOf(i * 5 + j));
}
#Override
public void onGestureCancelled(GestureOverlayView overlay, MotionEvent event) {
reset();
}
#Override
public void onGestureEnded(GestureOverlayView overlay, MotionEvent event) {
reset();
}
#Override
public void onGestureStarted(GestureOverlayView overlay, MotionEvent event) {
last = getAbove(event.getRawX(), event.getRawY());
draw();
}
TextView[][] tvs = new TextView[5][5];
TextView last = null;
And make the arraylist into an TextView[5][5]

Why moving of GroupView works bad?

I made two nested RelativeLayouts, filled one with some TextViews and made reaction on finger drag guesture.
But it works badly:
1) moving group leaves garbage traces as if background does not redraw
2) the column with leftMargin==800 does not draw
The XML layout code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/stator"
>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="0dp"
android:layout_marginTop="0dp"
android:id="#+id/mover"
android:background="#android:color/darker_gray"
>
</RelativeLayout>
</RelativeLayout>
The java code:
public class SymbolPadActivity extends Activity {
private RelativeLayout mover;
private RelativeLayout stator;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mover = (RelativeLayout) findViewById(R.id.mover);
RelativeLayout.LayoutParams labelParams;
TextView textView;
for(int leftMargin = 0; leftMargin<1500; leftMargin += 200) {
for(int topMargin=0; topMargin<800; topMargin += 80) {
// I can't omit these 3 lines
labelParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
labelParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
labelParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
labelParams.leftMargin = leftMargin;
labelParams.topMargin = topMargin;
textView = new TextView(this);
textView.setText("(" + leftMargin + "," + topMargin + ")");
mover.addView(textView, labelParams);
}
}
stator = (RelativeLayout) findViewById(R.id.stator);
stator.setOnTouchListener(new View.OnTouchListener() {
private int startleft, starttop;
private float startx, starty;
private boolean started;
#Override
public boolean onTouch(View v, MotionEvent event) {
if( event.getActionMasked() == MotionEvent.ACTION_DOWN ) {
started = true;
startx = event.getX();
starty = event.getY();
startleft = mover.getLeft();
starttop = mover.getTop();
return true;
}
else if( event.getActionMasked() == MotionEvent.ACTION_UP ) {
started = false;
startx = starty = 0;
return true;
}
else if( event.getActionMasked() == MotionEvent.ACTION_MOVE ) {
mover.setLeft( startleft + (int)(event.getX() - startx) );
mover.setTop( starttop + (int)(event.getY() - starty) );
return true;
}
else {
return false;
}
}
});
}
}
