unable to access Clipboard Content from foreground service in Android 10+

I know that we can't access clipboard content from background services in 10+ but there is an application that shows copied text on a floating widget in Android 10+ devices using foreground service here's that app. I want to achieve that functionality somehow! please help me.
My app is working fine in android P and lower devices!

Delete an item of a listView by sliding it with my finger on the side [duplicate]

This question already has answers here:
Swipe to delete a ListView Item
(2 answers)
Closed 5 years ago.
My goal is to delete an item of a listView by sliding it with my finger on the side. I've tried to put onTouchListener on layout which is on the ViewHolder class. I have several problems :
When i slide down or top with my finger, the list scroll, and the item keep his new position (it doesn't return to inital position)
If the first problem occurs, when i scroll down the list, several items have the same position as the first one.
If i succeed to slide the item to the limit i had defined, then the deleted item is not the good one all the time. In addition i have any alpha animation.
With onTouchListener, my onItemClick listener not working anymore. (I want to color the background of selected list item).
Here is the overview of what I am trying to do :
Please see my code below :
My Custom List Adapter
public class VisiteAdapter extends ArrayAdapter<Visite> {
private Visite visite = null;
private float _xDelta;
private float initialXPos;
private float initialTouchXPos;
private boolean haveAlreadyCheckXPos = false;
private List listeVisite = null;
public VisiteAdapter(Context context, List<Visite> items) {
super(context, R.layout.item_visite, items);
listeVisite = items;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
visite = getItem(position);
final View result;
if (convertView == null) {
viewHolder = new ViewHolder();
LayoutInflater vi = LayoutInflater.from(getContext());
convertView = vi.inflate(R.layout.item_visite, null);
viewHolder.nomCopro = (TextView) convertView.findViewById(R.id.listeNomCopro);
viewHolder.dateVisite = (TextView) convertView.findViewById(R.id.listDateVisite);
viewHolder.itemLayout = (LinearLayout) convertView.findViewById(R.id.itemLayout);
viewHolder.globalItem = (FrameLayout) convertView.findViewById(R.id.globalItem);
//OnTouchListener on the first layer of my item
viewHolder.itemLayout.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
int slideLimit = 150;
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
if(!haveAlreadyCheckXPos){
//get Initial X position of view.
initialXPos = v.getX();
haveAlreadyCheckXPos=true;
}
//initial X position of my finger when i touch the view
initialTouchXPos = event.getRawX();
//usefull value for translation
_xDelta = v.getX() - event.getRawX();
break;
case MotionEvent.ACTION_MOVE:
//Allow the view to slide to the left only. The view is blocked at a certain distance of the initial pos with the "slideLimit".
if(initialTouchXPos - event.getRawX() >= 0 && initialTouchXPos - event.getRawX() <= slideLimit){
//The sliding effect
v.animate()
.x(event.getRawX() + _xDelta)
.setDuration(0)
.start();
}
break;
case MotionEvent.ACTION_UP:
//if the view is near to the slideLimit
if(initialXPos - v.getX() >= slideLimit-20){
//item is remove from the list with an alpha animation (alpha animation doesn't work)
viewHolder.globalItem.animate().alpha(0.0f).setDuration(350).start();
Log.e("ListeVisite.adapter"," ITEM DELETE");
listeVisite.remove(position);
notifyDataSetChanged();
}else{
//View return to the initial position
TranslateAnimation returnToInitialPos = new TranslateAnimation(0, initialXPos - v.getX(), 0, 0);
returnToInitialPos.setDuration(500);
returnToInitialPos.setFillAfter(true);
v.startAnimation(returnToInitialPos);
}
break;
default:
return false;
}
return true;
}
});
result=convertView;
convertView.setTag(viewHolder);
}else{
viewHolder = (ViewHolder) convertView.getTag();
result=convertView;
}
if (viewHolder.nomCopro != null) {
viewHolder.nomCopro.setText("CoproID : "+visite.getCOPRO_REF());
}
if (viewHolder.dateVisite != null) {
viewHolder.dateVisite.setText(UsefulMethods.dateToString(visite.getV_DATE_VISITE(),"dd/MM/yyyy"));
}
//Selection of the item work with a boolean in the model. Look at the MainActivity class
if(visite.isSelected){
viewHolder.itemLayout.setBackgroundColor(ResourcesCompat.getColor(getContext().getResources(), R.color.colorPrimaryLight, null));
}else{
viewHolder.itemLayout.setBackgroundColor(ResourcesCompat.getColor(getContext().getResources(), R.color.white, null));
}
return convertView;
}
private static class ViewHolder {
TextView nomCopro;

How to toggle touch event between nested Relative layouts?

I have a Relative layout holds a surface view and another Relative layout (Nested)..
1 ) I want to receive touch events separately for Surface view, if touch events are out of child relative layout. ??
2) if my touch events falls on child relative layout, then the current touch event should not go to surface view.
How to achieve this toggle ???
Thanks in advance..!

i'm android beginner so don't know it very well so tell me how to solve it.
sorry for my bad english and grammer mistake.
thanks in advances

I solved this problem by myself. Here is the solution:
DragEvent.ACTION_DRAG_LOCATION:
//no action necessary
int y = Math.round(v.getY())+Math.round(event.getY());
int translatedY = y - mScrollDistance;
Log.i("translated",""+translatedY+" "+ mScrollDistance+" "+y);
int threshold =50 ;
// make a scrolling up due the y has passed the threshold
if (translatedY < 200) {
// make a scroll up by 30 px
myScrollView.smoothScrollBy(0, -15);
}
// make a autoscrolling down due y has passed the 500 px border
if (translatedY + threshold > 500) {
// make a scroll down by 30 px
myScrollView.smoothScrollBy(0, 15);
}
break;

I am trying to make something like customised quick badge with some buttons on it. I have successfully desgined it but when i am clicking on those buttons it does nothing. Can someone tell me where am i going wrong.

The problem is in DemoPopupWindow.onCreate method:
ViewGroup root = (ViewGroup) inflater.inflate(
R.layout.popup_grid_layout, null);
for (int i = 0, icount = root.getChildCount(); i < icount; i++) {
View v = root.getChildAt(i);
if (v instanceof TableRow) {
root will be RelativeLayout defined in popup_grid_layout.xml. Later you iterate through all its children and set onclick listeners only if child view is TableRow, which is never the case. I guess what you want there is to find horizontalScrollView1 view and do the same with its children instead, something like:
View horizontalScrollView1 = findViewById(R.id.horizontalScrollView1);
for (int i = 0, icount = horizontalScrollView1.getChildCount(); i < icount; i++) {
View v = horizontalScrollView1.getChildAt(i);
if (v instanceof TableRow) {
