Width of the balloon with a custom layout not adjusted properly when setting text dynamically

Please complete the following information:

• Library Version 1.3.1+
• Affected Device(s) All devices, in particular, Pixel 3a API 28

Describe the Bug: We are using Balloon.Factory() with a custom layout resource that includes several textViews. After setting text values dynamically, the width of the balloon is not resized to wrap its content (it is fixed with the initial value). As a result, the height of the content increases. The solution provided in #91 cannot be used anymore, since method measureTextWidth is private now. The issue can be easily reproduced using the demo application:

Step 1 - Add id to the TextView in the layout_custom_tag.xml:

  <TextView
    android:id="@+id/tagTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="12"
    android:textColor="@android:color/black"
    android:textSize="16sp"
    android:textStyle="bold"
    tools:ignore="HardcodedText" />

Step 2 - change the text of that tagTextView to a different value, i.e.:

customTagBalloon.getContentView().findViewById<TextView>(R.id.tagTextView).text = "Long text"

Step 3 - launch the application and click on the bottomNavBar. As a result, the height of the balloon increased, instead of the width. However, it works properly on version 1.3.0 of the library. Modified demo app to reproduce the issue is also available at: https://github.com/wkubaty/Balloon/tree/custom-layout-size-issue

Unexpected behavior on version 1.3.4:

Expected Behavior: The width of the balloon with a custom layout should be adjusted properly when setting content dynamically.

Proper behavior on version 1.3.0:

I found out that if you are using ConstrainLayout and have any view that has 0dp for the constrain, the lib will not adapt for what you see in the editor, instead, use match_parent or wrap_content for those views, or simply use LinearLayout

I will consider processing the changes internally. 🤔 Here is just the quick solution:

val label = customTagBalloon.getContentView().findViewById<TextView>(R.id.label)
label.text = "111111111111111111111344555"
val width = label.paint.measureText(label.text.toString())
label.maxWidth = width.toInt()
