BalloonPopup

Displays a round or squared popup attaching it to a View. Allows animations and automatic display and hide, or persistence of the balloon when updating its value. Uses the Builder pattern for maximum ease.



Setup

In your project's build.gradle file:

allprojects {

  repositories {

...

maven {
 url "https://jitpack.io" 
}

...
  
}
 
}
 

In your Application's or Module's build.gradle file:

dependencies {

  ...
  compile 'com.github.BeppiMenozzi:BalloonPopup:0.2.8'
  ... 
}
 

Minimal usage

BalloonPopup bp = BalloonPopup.Builder(getApplicationContext(), myView)

.text("myText")

.show();
 

To show it again:

bp.showAgain();
 

To display different text:

bp.updateText(newText);
 

Examples

In addition to the simple example included, this library is used in my Knob Selector library, that contains useful examples and an interesting way to use this library. Test it out.

Customize

Available methods in the Builder:

  bp = BalloonPopup.Builder(getApplicationContext(), findViewById(R.id.button))

.text("text")

// set the text displayed (String or resource)

.timeToLive(2000)

  // Millseconds before closing the popup. 0 = persistent

.animation(fade_and_pop)
 // animation style used. Available:

 // pop, scale, fade, fade75

 // and all the possible combinations.

 // When fade75 is used (up to alpha .75) the view is slightly transparent

.shape(rounded_square)

// Circle (oval) or rounded square

.bgColor(Color.CYAN)

  // unused yet

.fgColor(Color.RED)

// text color

.gravity(bg)

 // gravity relative to the attach view

.textSize(6)

 // text size

.offsetX(10)

 // offsets to move the position accordingly

.offsetY(15)

.positionOffset(10, 15)

.drawable(R.drawable.bg_circle) // custom background drawable

.layoutRes(R.layout.customview) // custom layout for the popup window

.show();

  // create, display and return the balloon 

Available methods on the balloon:



bp.isShowing();

// returns wether the balloon is currently visibile

 bp.restartLifeTime();

// restarts the time to live, postponing the closure

 bp.updateText();

  // updates the text and displays it again

 bp.updateTextSize();

 // updates text size and displays it again

 bp.updateFgColor();

  // updates text color and displays it again

 bp.updateBgColor();

  // updates background color: available only from Lollipop (>= 21)

 bp.updateOffset();

// updates position and displays it again

 bp.updateGravity();

  // updates gravity and displays it again

 bp.updateLifeTimeToLive();

 // updates time to live

 bp.showAgain();

// show again the previous balloon 

Most of these methods ask a boolean parameter restartLifeTime. If this is false, in case of update, if the balloon is already showing, its life is not made longer and its closure remains scheduled as before. As default this parameter is true (so whenever an update is done, the time to live is reset).

New in 0.2.8

  • Included alexandre-g additions: ** Allow custom views for dynamically built layouts ** Allow disabling tap-to-dismiss ** Allow to force showing only within screen bounds ** Allow dismissing popup

New in 0.2.2

  • bgcolor for >= Lollipop (21)
  • fixed crash if built inside onCreate()
  • increased minApk from 9 to 11

Known bugs

  • On emulators with version < 4.4.4 / KitKat / Api 19 it can crash.
  • It doesn't scroll when the attached view is in a scrollview.

Resources

This library add the ability to listen for drawable click events for TextView, EditText and AutoCompleteTextView normally added in XML with android:drawableStart etc... or in code with setCompoundDrawables(...) and similar.

With this library you can flat a layout used to side any widget with an ImageView or ImageButton added to listen for click on the icon, to one unique custom view.

SwipeableRV is a library that provides a fast and convenient way to implement the 'swipe to dismiss' feature in Recycler View, as seen in apps such as Messenger.

SwipeableRV wraps around ItemTouchHelper from the Android Support Library. Therefore, developers do not need to do any extra work on ItemTouchHelper.Callback themselves. Instead they can just focus on creating a recycler view, adapter, and view holder as normal, plus some minimal work on specifying some details such as supported swipe directions, deletion message or icon.

A custom view that gives the user a look and feel of selecting options with smoother slider animation.

With this SDK you can access the API behind the DRAE (Diccionario de la Real Academia Española, the official spanish dictionary) in order to use it in your own app.

Shortify is used for minimizing your coding effort in your development environment. It has some builtin method and classes which helps you in creating mostly used element and tasks in Android app.

Android library handling flashlight for camera and camera2 api. Added support for handling display/screen light.
