        jcenter()
    }

Add compile 'com.cpiz.bubbleview:bubbleview:{X.Y.Z}' to your module-level build.gradle(see X.Y.Z in Releases)

dependencies {
    ...
    compile 'com.cpiz.bubbleview:bubbleview:{X.Y.Z}'

Specify the direction of arrow

You can use app:bb_arrowDirection attribute to specify the direction of arrow. Its value can be: Left, Up, Right, Down or None. Arrow will be placed in the middle of the corresponding edge of bubble.

<com.cpiz.android.bubbleview.BubbleTextView
    android:id="@+id/bb1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_toLeftOf="@id/iv1"
    android:padding="6dp"
    android:text="ArrowRight"
    android:textColor="@android:color/white"
    app:bb_arrowDirection="Right"
    app:bb_cornerRadius="4dp"/>

Point arrow to a specific target

You can use app:bb_arrowTo attribute to specify the id of target view. The direction of arrow will be calculated automatically and it will point to the center of target.

<RelativeLayout
    android:id="@+id/group2"
    android:layout_width="match_parent"
    android:layout_height="180dp"
    android:layout_marginBottom="30dp"
    android:background="#bdc3c7"
    android:padding="10dp">

    <ImageView
        android:id="@+id/iv2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:layout_margin="4dp"
        android:src="@android:drawable/ic_btn_speak_now"
        android:tint="#FFFFFF"/>

    <com.cpiz.android.bubbleview.BubbleTextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@id/iv2"
        android:layout_toLeftOf="@id/iv2"
        android:padding="6dp"
        android:text="Get your apps ready for Android 6.0 Marshmallow! "
        android:textColor="@android:color/white"
        app:bb_arrowTo="@id/iv2"/>
</RelativeLayout>

    app:bb_arrowHeight="10dp"
    app:bb_arrowOffset="30dp"
    app:bb_arrowWidth="40dp"
    app:bb_borderColor="@color/colorPrimary"
    app:bb_borderWidth="6dp"
    app:bb_cornerBottomLeftRadius="0dp"
    app:bb_cornerBottomRightRadius="10dp"
    app:bb_cornerTopLeftRadius="0dp"
    app:bb_cornerTopRightRadius="4dp"
    app:bb_fillColor="@android:color/holo_red_light"
    app:bb_fillPadding="4dp"/>

Use it as layout container

---

Beside using BubbleTextView to display text, you can also use

• BubbleRelativeLayout
• BubbleLinearLayout
• BubbleFrameLayout

as bubble layout container and put customized content into it.

Popup

---

Can use BubblePopupWindow to wrap bubble, and show as popup.

• Support touch outside to close
• Support touch inside to close
• Support close in time

    View rootView = LayoutInflater.from(this).inflate(R.layout.simple_text_bubble, null);
    BubbleTextView bubbleView = (BubbleTextView) rootView.findViewById(R.id.popup_bubble);
    window = new BubblePopupWindow(rootView, bubbleView);
    window.setCancelOnTouch(true);
    window.setCancelOnTouchOutside(true);
    window.setCancelOnLater(3000);
    window.showArrowTo(v, BubbleStyle.ArrowDirection.Left);

Misc.

• Invoke methods like setBackground/setBackgroundColor of BubbleView will make the style settings invalid.
