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).
