如何使单行 EditText 在使用特定尺寸时正确绘制自身

我需要以编程方式设置 EditText 小部件的高度和宽度。我正在使用相对布局来执行此操作，并且就大小而言它工作正常，但实际的小部件无法正确绘制自身：

我希望它会像这样绘制（如果我将高度设置为 ViewGroup.LayoutParams.WRAP_CONTENT 而不是我请求的高度 - 有时会出现这种情况）：在此处输入图像描述

有什么想法吗？

请注意，我无法切换到DIP:s（dpi 独立性实际上已经由使用此代码的引擎处理）。另请注意，我还没有找到任何可以修复错误行为的 setTextSize() 值。

这就是我创建小部件的方式：

  EditText et = new EditText(this);
  et.setFocusable(true);
  et.setSingleLine(true);
  et.setHint(label);
  et.setText(text);
  et.setTextSize(TypedValue.COMPLEX_UNIT_PX,(h/3)+5);
  et.setId(cn); 
  rllp = new RelativeLayout.LayoutParams(w,h);
  rllp.leftMargin = x;
  rllp.topMargin = y;
  layout.addView(et,rllp);

I need to set the height and width of a EditText widget programmatically. I am using a RelativeLayout to do this, and it works fine as far as the size goes, but the actual widget paints itself incorrectly:

Incorrect Drawing of EditText

I would have expected it to paint like this (which it will if I set the height to ViewGroup.LayoutParams.WRAP_CONTENT instead of my requested height - sometimes):
enter image description here

Any ideas?

Please note that I can't switch to DIP:s (dpi independence is actually already handled by the engine that use this code). Also note that I haven't found any value of setTextSize() that fix the misbehaviour.

This is how I create my widget:

  EditText et = new EditText(this);
  et.setFocusable(true);
  et.setSingleLine(true);
  et.setHint(label);
  et.setText(text);
  et.setTextSize(TypedValue.COMPLEX_UNIT_PX,(h/3)+5);
  et.setId(cn); 
  rllp = new RelativeLayout.LayoutParams(w,h);
  rllp.leftMargin = x;
  rllp.topMargin = y;
  layout.addView(et,rllp);
