【问题描述】：
我正面临多行 editTextView 的问题。我正在以编程方式将单行 edittext 视图和多行 edittext 视图添加到线性布局（请参阅下面 xml 的 customlayout 线性布局）并设置背景。一切工作正常，但当文本是在多行edittextview中输入，多行edittextview的背景正在缩小，并在第2行或第3行背景中进一步输入文本混乱，并且所有单行edittextview的背景都消失了。请帮助我解决这个问题..提前感谢
private EditText getEditText(String sHint,Boolean isMultiLine,Drawable drwable)
{
EditText editTxt;
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.topMargin=2;
params.leftMargin=40;
params.rightMargin=20;
params.bottomMargin=10;
params.gravity = Gravity.CENTER_HORIZONTAL;
editTxt = new EditText(this);
editTxt.setLayoutParams(params);
editTxt.setTextAppearance(this, android.R.style.TextAppearance_Medium);
editTxt.setHint(sHint);
editTxt.setBackground(drwable);
editTxt.setGravity(Gravity.CENTER);
editTxt.setTextColor(Color.WHITE);
editTxt.setTypeface(null, Typeface.ITALIC);
if(isMultiLine==true)
{
editTxt.setLines(3);
editTxt.setSingleLine(false);
editTxt.setInputType(EditorInfo.TYPE_CLASS_TEXT|EditorInfo.TYPE_TEXT_FLAG_MULTI_LINE);
}
else
{
editTxt.setLines(1);
editTxt.setSingleLine(true);
}
return editTxt;
}
