Usage

Basic

Here's a basic example

public class ActivityMain extends AppCompatActivity {
        
    @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            
            Button btn = (Button) findViewById(R.id.btn_popup);
            
            // Create a foo TextView
            TextView textView = new TextView(this);
            textView.setText("Hello, Foo!");
            
            LongPressPopup popup = new LongPressPopupBuilder(this)// A Context object for the builder constructor
                    .setTarget(btn)// The View which will open the popup if long pressed
                    .setPopupView(textView)// The View to show when long pressed 
                    .build();// This will give you a LongPressPopup object
                    
            // You can also chain it to the .build() mehod call above without declaring the "popup" variable before 
            popup.register();// From this moment, the touch events are registered and, if long pressed, will show the given view inside the popup, call unregister() to stop
        }
}

Advanced

Here's a complete example with all the options

public class ActivityMain extends AppCompatActivity implements PopupInflaterListener,
            PopupStateListener, PopupOnHoverListener, View.OnClickListener {

    private static final String TAG = ActivityMain.class.getSimpleName();
     
    private TextView mTxtPopup;   
        
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        Button btn = (Button) findViewById(R.id.btn_popup);
        
        LongPressPopup popup = new LongPressPopupBuilder(this)
                        .setTarget(btn)
                        //.setPopupView(textView)// Not using this time
                        .setPopupView(R.layout.popup_layout, this)
                        .setLongPressDuration(750)
                        .setDismissOnLongPressStop(false)
                        .setDismissOnTouchOutside(false)
                        .setDismissOnBackPressed(false)
                        .setCancelTouchOnDragOutsideView(true)
                        .setLongPressReleaseListener(this)
                        .setOnHoverListener(this)
                        .setPopupListener(this)
                        .setTag("PopupFoo")
                        .setAnimationType(LongPressPopup.ANIMATION_TYPE_FROM_CENTER)
                        .build();
                
        // You can also chain it to the .build() mehod call above without declaring the "popup" variable before 
        popup.register();
    }
    
    
    // Popup inflater listener
    @Override
    public void onViewInflated(@Nullable String popupTag, View root) {
        mTxtPopup = (TextView) root.findViewById(R.id.txt_popup);
    }
    
    
    // Touch released on a View listener
    @Override
    public void onClick(View view) {
        if (mTxtPopup != null && view.getId() == mTxtPopup.getId()) {
            Toast.makeText(ActivityMain.this, "TextView Clicked!", Toast.LENGTH_SHORT).show();
        }
    }
    
    
    // PopupStateListener
    @Override
    public void onPopupShow(@Nullable String popupTag) {
        if(mTxtPopup != null) {
            mTxtPopup.setText("FooBar!");
        }
    }
    
    @Override
    public void onPopupDismiss(@Nullable String popupTag) {
        Toast.makeText(this, "Popup dismissed!", Toast.LENGTH_SHORT).show();
    }
    
    
    // Hover state listener
    @Override
    public void onHoverChanged(View view, boolean isHovered) {
        Log.e(TAG, "Hover change: " + isHovered + " on View " + view.getClass().getSimpleName());
    }
}

And here are the functions you can use to customize the Popup and it's behaviour from the LongPressPopupBuilder class:

public LongPressPopupBuilder setTarget(View target) (null by default)
Select which view will show the popup view if long pressed
public LongPressPopupBuilder setPopupView(View popupView) (null by default)
Select the view that will be shown inside the popup
public LongPressPopupBuilder setPopupView(@LayoutRes int popupViewRes, PopupInflaterListener inflaterListener) (0, null by default)
Select the view that will be shown inside the popup, and give the popup that will be
called when the view is inflated (not necessarily when shown, so not load images and so on in this callback,
just take the views like in the OnCreate method of an Activity)
public LongPressPopupBuilder setLongPressDuration(@IntRange(from = 1) int duration) (500 by default)
Pretty self explanatory right? **Captain here, the long press time needed to show the popup
public LongPressPopupBuilder setDismissOnLongPressStop(boolean dismissOnPressStop) (true by default)
Set if the popup will be dismissed when the user releases the finger (if released on a View inside
the popup, the View's or the given OnClickListener will be called)
public LongPressPopupBuilder setDismissOnTouchOutside(boolean dismissOnTouchOutside) (true by default)
If setDismissOnLongPressStop(boolean dismissOnPressStop) is set to false, you can choose to make
the popup dismiss or not if the user touch outside it with this boolean
public LongPressPopupBuilder setDismissOnBackPressed(boolean dismissOnBackPressed) (true by default)
If setDismissOnLongPressStop(boolean dismissOnPressStop) is set to false, you can choose to make
the popup dismiss or not if the user press the back button
public LongPressPopupBuilder setCancelTouchOnDragOutsideView(boolean cancelOnDragOutside) (true by default)
Set if the long press timer will stop or not if the user drag the finger outside the target View
(If the target View is inside a scrolling parent, when scrolling vertically the long press timer
will be automatically stopped
public LongPressPopupBuilder setLongPressReleaseListener(View.OnClickListener listener) (null by default)
This is a standard OnClickListener, which will be called if the user release the finger on a view inside
the popup, you can use this method or set a standard OnClickListener on the View you want, it will be called
automatically for you
public LongPressPopupBuilder setOnHoverListener(PopupOnHoverListener listener) (null by default)
This listener will be called every time the user keeps dragging it's finger inside or outside the popup
views, with a View reference and a boolean with the hover state
public LongPressPopupBuilder setPopupListener(PopupStateListener popupListener) (null by default)
This listener will be called when the popup is shown or dismissed, use this listener to load images or compile text views and so on
public LongPressPopupBuilder setTag(String tag) (null by default)
This method sets a tag on the LongPressPopup, the given tag will be returned in all the listeners. You can also set it in the build(String tag)
method
public LongPressPopupBuilder setAnimationType(@LongPressPopup.AnimationType int animationType) (none by default)
This method set the opening and closing animation for the popup, can be none or from-to Bottom, Top, Right, Left, Center

Also, the LongPressPopup class gives some utility methods, like

public void register()
Which means that the popup is listening for touch events on the given view to show itself
public void unregister()
Which makes to popup stop listening for touch events and dismiss itself if open
public void showNow()
Which shows immediately the popup
public void dismissNow()
Which dismiss immediately the popup if open

Problem with padding

Hi.. I have a linearlayout for the popup, with an imageview and two textviews below the imageview. The first time i open a popup, the image seems to have a small top padding. If i open the same popup again, the padding is gone. Anyone has an idea, what happens there?

setLongPressDuration?

Hi, popup keeps on showing even if I increase duration. Below is my code:

 final LongPressPopup popup = new LongPressPopupBuilder(holder.itemView.getContext())
                .setTarget(holder.itemView.findViewById(R.id.row_product_item_image))
                .setPopupView(v)
                .setLongPressDuration(1250)
                .setDismissOnLongPressStop(true)
                .build();
        v.findViewById(R.id.btnPopUpCancel).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                popup.dismissNow();
            }
        });
        popup.register();

I also have setDismissOnLongPressStop, but it doesn't dismiss unless I tap on the cancel button I added to v (Popup view), and the popup still shows when the new activity is on the screen. LongPressDuration just delays it and doesn't reset if user stops tapping target view

Show image on longpress.

When I click on the image it sometimes appears with a zoom there and I have to open the popup again so that it appears correctly, besides a white left side margin.

Follows the first image after the first click with a strange zoom.

Follow the second image again after the click already presented normally. Both are the same pictures.

To the right side can be seen a white margin what can be this difference?

His lib is incredible, and from the outset his enormous attention and help.

Change the dispatch click system

Would you consider changing the way the library dispatches the click to the leaf nodes only by instead checking if non-leaf nodes have a click listener attached and giving priority to those? This means that if i have a ViewGroup with a click listener and some items inside, everywhere i lift my finger in this view group, the click will be dispatched to the view group instead of the children.

Alternatively we can also inject this behavior and make it custmizable.

Happy to open a PR for this and contribute just let me know what you think.

SwipeRefreshLayout breaks the ability to drag finger to the view

I really like this library :) But I discovered an issue: I am using an swipeRefreshLayout around my recyclerview and when I am long pressing an item in this recyclerview, the popup shows up, but when I want to drag my finger down to the buttons of the view, the swipeRefreshLayout gets triggered and the popup closes. How can I disable the swipeRefreshLayout while the popup is open?
