How to get a reference to the layout from within a custom TextView


How to get a reference to the layout from within a custom TextView

should help you out This is probably an easy question to answer, but searches were just turning up things like inflating and xml layouts, which isn't what I want. , This solution finally worked for me.
From the main activity:
code :
inputWindow.setText(displayText);
inputWindow.post(new Runnable() {

    @Override
    public void run() {

        inputWindow.setCursorLocation(glyphCursorPosition);
    }

});
public void setCursorLocation(int characterOffset) {

    Layout layout = this.getLayout();

    int line = layout.getLineForOffset(characterOffset);
    mCursorX = layout.getPrimaryHorizontal(characterOffset);
    mCursorBaseY = layout.getLineBaseline(line);
    mCursorBottomY = layout.getLineBottom(line);
    mCursorAscentY = layout.getLineAscent(line);

    this.invalidate();
}

this one helps. You can assign tags (integers) to the different views and query the tag number to see which view called the method. Look for the tag property on the view:
code :
tag

The receiver’s tag, an integer that you can use to identify view objects in your application.

@property(nonatomic) NSInteger tag

wish helps you I have a custom textView, which placed inside of LinearLayout , You can substitute the linear layout with the textView:
code :
<?xml version="1.0" encoding="utf-8"?>

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:maxLines="2"
    android:ellipsize="end"
    tools:text="Only on 22 of July, 2019"
    android:textColor="@color/white" 
    />
class CustomTimerView(context: Context, attributeSet: AttributeSet) : TextView(context, attributeSet) {

    init {
        TextView.inflate(context, R.layout.custom_timer_layout, null)
    }

    fun setDates(ob: Promo) {
        val startDate = getStartDate(ob)
        val endDate = getEndDate(ob)

        if (startDate.get(Calendar.MONTH) != endDate.get(Calendar.MONTH)) {
            this.text = getInDifferentMonths(context!!, ob)
        } else {
            if (startDate.get(Calendar.DAY_OF_MONTH) == endDate.get(Calendar.DAY_OF_MONTH)) {
                this.text = getOnlyOneDay(context!!, ob)
            } else {
                this.text = getInOneMonth(context!!, ob)
            }
        }

wish of those help You almost had it there in your original code. You saved the View returned by LayoutInflater, so that's the one you should use when calling findViewById() so it must be dialogLayout.findViewById(...). I was having the same issue myself and works like charm now.
