Anko: The gravity is not working on the TextView in some situation.

Created on 4 Jan 2016 · 5Comments · Source: Kotlin/anko

When I’m trying to implement multiple TextViews in the LinearLayout, the all gravity options are not applied to both horizontal and vertical alignment.

This code block is an example for the Gravity.CENTER option:

optionsContainer.addView(context.linearLayout {   
    lparams(width = matchParent, height = matchParent)      

    textView("1") {       
        gravity = Gravity.CENTER  
    }.lparams(width = 0, height = matchParent, weight = 1f)     
    textView("2") {       
        gravity = Gravity.CENTER  
    }.lparams(width = 0, height = matchParent, weight = 1f) 
})

The FrameLayout of optionsContainer is following:

<FrameLayout     
    android:id="@+id/options_container"     
    android:layout_width="match_parent"     
    android:layout_height="56dp”     
    android:layout_alignParentBottom="true" />

In my opinion, this problem can be fixed with attached code block below:

inline fun ViewManager.textView(text: CharSequence?, gravity: Int, init: android.widget.TextView.() -> Unit): android.widget.TextView {     
    return ankoView(`$$Anko$Factories$Sdk23View`.TEXT_VIEW) {         
        init()         
        setText(text)         
        setGravity(gravity)     
    }
 }

Thank you!

+1 on this, I would add that IDEA is completely lost because of this.

I just spent an hour wondering why my text wasn't centered, because IDEA told me I was using the right gravity.

I recommend renaming the layout's gravity to layoutGravity and the textview's gravity to textGravity.

For now, you have to use this.gravity to set the text gravity in a TextView:

textView {
    this.gravity = Gravity.CENTER
}
