Problem with the auto-dismiss of dialog in setOnLongClickListener

I have problem with setOnLongClickListener. When I use this method I want the dialog, which will open, to automatically close by itself (which the method's return false should do) when I take my finger off the screen. Is it possible to do this with this method, or are there other suitable methods?
Create Dialog
protected void showDialogLongClick(final int position){
final Dialog dialog = new Dialog(activity);
dialog.setCancelable(true);
View v = activity.getLayoutInflater().inflate(R.layout.onlongclick_card_mygift,null);
dialog.setContentView(v);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
nameLong = v.findViewById(R.id.name_longclick);
descriptionLong = v.findViewById(R.id.gift_description);
addressLong = v.findViewById(R.id.gift_address);
imageCategory = v.findViewById(R.id.small_category);
nameLong.setText(myGift.get(position).getName());
descriptionLong.setText(myGift.get(position).getDescription());
addressLong.setText(myGift.get(position).getAddress());
String cat = myGift.get(position).getCategory();
changeCategoryImage(cat, imageCategory);
dialog.show();
}
Listener
holder.card.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
showDialogLongClick(position);
return false;
}
});

view.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
//Dismiss the dialog
}
return false;
}
});
view.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View view) {
//Create the dialog
return true;
}
});
Use setOnLongClickListener for creating the dialog and use setOnTouchListener for dismissing the dialog.
So you should add setOnTouchListener to the view. Call dialog.dismiss() when MotionEvent action is MotionEvent.ACTION_UP (user lifts his finger).
If the view is inside a scroll view the views onTouchListener does not get called. A simple solution is to add an onTouchListener to the scroll view and dismiss the dialog when user lifts his finger.
scrollView.setOnTouchListener( new View.OnTouchListener(){
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
//Dismiss the dialog
return true;
}
return false;
}
});

Distinguish two finger rotation and simple tap

In my fragment I have a TextView and underneath there are two buttons.
I need to implement a OnTouchListener to do two things:
When I rotate my two fingers, the TeXtView will rotate
When I tap the TeXtView, the buttons underneath are called
Right now it doesnt work but I cant find better solution.

JAVA:
Btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
player.setText(String.valueOf(++life));
}
});
mRotationDetector = new RotationGestureDetector(this);
TV.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
int maskedAction = event.getActionMasked();
switch (maskedAction) {
case MotionEvent.ACTION_DOWN: {

}
case MotionEvent.ACTION_OUTSIDE: {
return false;
}
case MotionEvent.ACTION_MOVE: {
mRotationDetector.onTouchEvent(event);
break;
}
}
return true;
}
});

Ok, after a week I found the answer. I needed to dispatch my MotionEvent to parent of my buttons using dispatchTouchEvent. ACTION_POINTER_DOWN is for checking if user uses two fingers.
Now rotation goes to mRotationDetector and taps goes to onClickListeners of the buttons underneath the TextView player.
JAVA:
player.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
MotionEvent me = MotionEvent.obtain(event);
mRotationDetector.onTouchEvent(me);
switch (event.getActionMasked()){
case (MotionEvent.ACTION_DOWN):
flag=true;
break;
case(MotionEvent.ACTION_POINTER_DOWN):
flag=false;
break;
}
buttons.dispatchTouchEvent(event);
return true;
}
});

OnTouchListener on LinearLayout that is behind buttons

I am working on an Android application using C# in Xamarin. In my axml file, I have a LinearLayout with a certain ID that I have assigned a onTouchListener to. The problem is that as long as the buttons I have in my design are on top of the linearLayout, the onTouchListener is never triggered. If I set one of the buttons to invisible, then it works.
Is it possible to still have the onTouchListener react even though there are Controls in the way?
This is my axml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="horizontal"
android:layout_weight="1">
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="1"
android:layout_marginBottom="0.0dp"
android:background="#android:color/holo_green_light"
android:soundEffectsEnabled="false" />
<Button
android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="2"
android:background="#android:color/holo_blue_light" />
</LinearLayout>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1">
<Button
android:id="#+id/button3"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="3"
android:background="#android:color/holo_red_light" />
<Button
android:id="#+id/button4"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="4"
android:background="#android:color/holo_orange_light" />
</LinearLayout>
</LinearLayout>
This is how I set the onTouchlistener for the linearLayout:
LinearLayout linLay = FindViewById<LinearLayout>(Resource.Id.LinearLayout1);
linLay.SetOnTouchListener(new MyTouchListener(this));
This is a custom touch listener class:
public class MyTouchListener : Java.Lang.Object, View.IOnTouchListener
{
Context activityContext;
public MyTouchListener(Context ac)
{
activityContext = ac;
}
public bool OnTouch(View v, MotionEvent e)
{
float x = 0.0f;
float y = 0.0f;
if (e.Action == MotionEventActions.Down)
{
// do stuff
x = e.GetX();
y = e.GetY();
Toast.MakeText(activityContext, x.ToString(), ToastLength.Short).Show();
return true;
}
//if (e.Action == MotionEventActions.Up)
//{
// // do other stuff
// return true;
//}
return true;
}
}
And finally, this is how I set up the button click listener:
Button button = FindViewById<Button>(Resource.Id.button1);
button.Click += (s,e) =>
{
//int i = count % s.Count;
//if(i > 28)
// Toast.MakeText(this, button.GetX().ToString(), ToastLength.Short).Show();
button.Text = string.Format("{0}", count++);
};

You have to intercept the touch event. In order to do that you have to subclass LinearLayout and override onInterceptTouchEvent():
public class MyLinearLayout extends LinearLayout {
public MyLinearLayout(Context context) {
super(context);
}
public MyLinearLayout(Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
}
public MyLinearLayout(Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
Toast.makeText(getContext(), "onTouch", Toast.LENGTH_SHORT).show();
return true;
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return true;
}
}
Your xml:
<?xml version="1.0" encoding="utf-8"?>
<com.your.package.MyLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="horizontal"
android:layout_weight="1">
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="1"
android:layout_marginBottom="0.0dp"
android:background="#android:color/holo_green_light"
android:soundEffectsEnabled="false" />
<Button
android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="2"
android:visibility="invisible"
android:background="#android:color/holo_blue_light" />
</LinearLayout>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1">
<Button
android:id="#+id/button3"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="3"
android:background="#android:color/holo_red_light" />
<Button
android:id="#+id/button4"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="4"
android:background="#android:color/holo_orange_light" />
</LinearLayout>
</com.your.package.MyLinearLayout>
Now any touch event on the layout will be handled by your custom MyLinearLayout.

You need to extend (inherent) the parent linear layout so that you can intercept touch events from the nested children layouts. Override these two methods to receive touches from the children. Then in your xml you will add "myCustomLinearLayout" or whatever you name the your custom linear layout class. It should be pretty similar in C# / Xamarin.
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return true; // With this i tell my layout to consume all the touch events from its childs
}
#Override
public boolean onTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
// Log.d(TAG, String.format("ACTION_DOWN | x:%s y:%s",
break;
case MotionEvent.ACTION_MOVE:
//Log.d(TAG, String.format("ACTION_MOVE | x:%s y:%s",
break;
case MotionEvent.ACTION_UP:
break;
}
return true;
}

How to make a Layout listener ignore views on top of it - android

I have a LinearLayout and I want to see when a user has touched it, and has released their finger. I thought I could do this by adding a onTouch listener and checking the event. This linearLayout holds a bunch of buttons.
My problem isn't the listener not working, it just isn't doing what I thought it would do. The listener only gets activated if ONLY the layout has been touched, which makes sense, but isn't what I want. If the user touches a button inside of the layout the layout listener isn't called, and I want it to be called.
Here is my code:
java code:
ll = (LinearLayout)findViewById(R.id.CategorySelect_lLayout_noID);
ll.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN){
Toast.makeText(CategorySelect.this, "action DOWN called", Toast.LENGTH_SHORT).show();
return true;
}
if(event.getAction() == MotionEvent.ACTION_UP){
Toast.makeText(CategorySelect.this, "action Up called", Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
});
my xml:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="400dp"
android:layout_alignParentBottom="true"

This is the ScrollAbleLinearLayout class:
package com.tdubstudios.soundboard.hungergames;
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.LinearLayout;
public class ScrollAbleLinearLayout extends LinearLayout {
public ScrollAbleLinearLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
requestDisallowInterceptTouchEvent(true); // Tell parents not to use this event
return false; // Tell children not to use this event
}
}
Yes I know the naming on some things have changed from my previous code, that is because I changed it to hide what type of app I was making (from search results). However for whatever reason I no long care, so that's the reasoning behind that.
Thanks.
THIRD EDIT:
So I'm currently using
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
//requestDisallowInterceptTouchEvent(true); // Tell parents not to use this event
if(event.getAction() == MotionEvent.ACTION_DOWN){
return false;
}
if(event.getAction() == MotionEvent.ACTION_UP){
return false;
}
return true; // Tell children not to use this event
}
And it works the way I want it to, however it isn't practical. For it to actually register the button clicks you have to make sure you don't move your finger at all left/right/up/down. It has to be like exactly down and exactly up. I was trying to add a onFling method, and then tracking the distance the finger as moved. And if it has moved less then x amount of pixels then make the main method return false which will allow the buttons to work, but if it was actually a swipe/move then the button doesn't need to get activated. Here is what I mean:
#Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
if (Math.abs(e1.getY() - e2.getY()) > MORE_THAN_X_INT) {
booleanVar = false;
return false;
}else{
booleanVar = true;
}
return false;
}
Then doing:
Override
public boolean onInterceptTouchEvent(MotionEvent event) {
//requestDisallowInterceptTouchEvent(true); // Tell parents not to use this event
if(event.getAction() == MotionEvent.ACTION_DOWN){
return false;
}
if(event.getAction() == MotionEvent.ACTION_UP){
return false;
}
return booleanVar; // Tell children not to use this event
}
I think that would work, but I can't test it because there isn't a onFling method for extends LinearLayout
Any suggestions?
Please note my returning true/false might be backwards, I'm not sure it's kind of confusing me. But if someone could lead me in a way to making that onFling method I can mess around with it to get it the correct values.
I have
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
//requestDisallowInterceptTouchEvent(true); // Tell parents not to use this event
while(event.getAction() == MotionEvent.ACTION_DOWN){
return true;
}
while(event.getAction() == MotionEvent.ACTION_UP){
return true;
}
return false; // Tell children not to use this event
}
and my buttons are never click able. But the ontouch listener works perfectly haha :|

I would recommend extending LinearLayout and using onInterceptTouchEvent to catch the touch event, then return true to force its children to not receive the events.
Something like this:
public class MyLinearLayout extends LinearLayout {
public MyLinearLayout(Context context) {
super(context);
}
public MyLinearLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyLinearLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
return true; // Tell children not to use this event
}
}
And, then in your XML, change LinearLayout to com.yourpackagename.MyLinearLayout.
Addendum: If you want both the Buttons and the LinearLayout to receive the event, you can change the onInterceptTouchEvent to this:
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
// Whatever touch event code you want, using the "event" variable
return false; // Allow children to use the event
}

So I never really found the answer to my question, but I found a way that works. Instead of putting a listener on the layout, I am just adding the onTouchEvent method for the full activity rather than a specific view.
#Override
public boolean onTouchEvent(MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN){
Toast.makeText(CategorySelect.this, "action DOWN called", Toast.LENGTH_SHORT).show();
}
if(event.getAction() == MotionEvent.ACTION_UP){
Toast.makeText(CategorySelect.this, "action Up called", Toast.LENGTH_SHORT).show();
}
return super.onTouchEvent(event);
}
It doesn't effect any of the buttons, so it's exactly what I wanted. Thank you so much Soxxeh for working with me.
