EditText高度变化的麻烦

Question

我有动态改变身高的char* str = "Hello, World"。所以编辑文本时遇到问题..文本被隐藏，请看截图：

代码：

EditText

那么，我做错了什么？

布局：

final EditText editText = new EditText(getContext());
editText.setHint("?");

editText.setFilters(new InputFilter[]{new InputFilter.LengthFilter(maxAnswerLength.length())});
float measureText = editText.getPaint().measureText(maxAnswerLength);
editText.setWidth(editText.getPaddingLeft() + editText.getPaddingRight() + (int) measureText);
editText.setGravity(Gravity.CENTER);
editText.setTextSize(TEXT_SIZE);
editText.setSingleLine(true);

addView(editText);

editText.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

    private int measuredHeight;

    @Override
    public void onGlobalLayout() {
        if (measuredHeight == 0) {
            ViewGroup.LayoutParams layoutParams = editText.getLayoutParams();
            measuredHeight = editText.getMeasuredHeight();
            layoutParams.height = measuredHeight / 2;
            editText.setLayoutParams(layoutParams);
        }
    }
});

谢谢大家。我找到了解决这个问题的方法：

editText.setPadding(-5, -5, -5, -3);

感谢。
