推荐答案
经过大量的努力，我终于解决了这个问题，但仍然无法弄清实际问题.我所做的是我写了一个saperate函数来获取多行文本.它像魅力一样运作
After lot of juggling finally i solved the issue but still i could not figured-out the actual issue.What i did is i wrote a saperate function to get multiline text. it worked like a charm
private EditText getMultiLineEditText(String sHint,int id,Drawable drwable,String tag,int fldType,int fldFlag)
{
EditText editTxt;
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
// params.gravity = Gravity.CENTER;
params.topMargin=2;
params.leftMargin=40;
params.rightMargin=20;
params.bottomMargin=10;
params.weight=1;
params.gravity = Gravity.CENTER_HORIZONTAL;
editTxt = new EditText(this);
editTxt.setLayoutParams(params);
editTxt.setId(id);
editTxt.setInputType(EditorInfo.TYPE_CLASS_TEXT|EditorInfo.TYPE_TEXT_FLAG_MULTI_LINE);
editTxt.setLines(3);
editTxt.setMaxLines(3);
editTxt.setSingleLine(false);
editTxt.setTextAppearance(this, android.R.style.TextAppearance_Medium);
editTxt.setHint(sHint);
editTxt.setContentDescription(1+"");
editTxt.setBackground( getResources().getDrawable(R.drawable.rcornerx));
editTxt.setGravity(Gravity.CENTER);
editTxt.setTextColor(Color.WHITE);
editTxt.setTypeface(null, Typeface.ITALIC);
editTxt.setTag(id+"-"+tag);
editTxt.setCompoundDrawablePadding(10);
return editTxt;
}
