C# is the same as Java in this respect; consider the following program: using System; class Base { public Base () { Console.WriteLine (“Base..ctor”); M (); } public virtual … Read more
Try the following instead: line1Size = a.getDimensionPixelSize(R.styleable.StackedTextView_line1_textSize, 0); line2Size = a.getDimensionPixelSize(R.styleable.StackedTextView_line2_textSize, 0); if (line1Size > 0) { holdr.textLine1.setTextSize(TypedValue.COMPLEX_UNIT_PX, line1Size); } if (line2Size > 0) { holdr.textLine2.setTextSize(TypedValue.COMPLEX_UNIT_PX, line2Size); }
I just changed: xmlns:app=”http://schemas.android.com/apk/res-auto” to: xmlns:app=”http://schemas.android.com/apk/lib/com.app.chasebank” and it stopped generating the errors, com.app.chasebank is the name of the package.

Try android:includeFontPadding=”false” to see if it helps. In my experience that will help a little bit, but there’s no way of reducing the TextView dimensions to the exact pixel-perfect text size. The only alternative, which may or may not give better results, is to cheat a bit and hard-wire the dimensions to match the text … Read more

isInEditMode()should be used inside the Custom View constructor. Try the following code: public class GraphView extends View implements Grapher { public GraphView(Context context, AttributeSet attrs) { super(context, attrs); if(!isInEditMode()) init(context); } public GraphView(Context context) { super(context); if(!isInEditMode()){ touchHandler = new TouchHandler(this); init(context); } }
Just inform the root, and whether you want to attach to it init { // inflate binding and add as view binding = ResultProfileBinding.inflate(LayoutInflater.from(context), this) } or init { // inflate binding and add as view binding = ResultProfileBinding.inflate(LayoutInflater.from(context), this, true) } which inflate method to use will depend on the root layout type in … Read more
