Android 多行 Edittext 在输入文本时缩小/迷惑背景

Question

我面临多行问题 editTextView.I 我正在向线性布局添加单行编辑文本视图和多行编辑文本视图（请参考下面的自定义布局线性布局 xml）并设置 background.Everything 工作正常，但是当在多行 edittextview 中输入文本时，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迷失方向，所有单行 edittextview 的背景 disappearing.Please 帮助我解决这个问题问题..提前致谢

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;

}

经过大量的尝试，我终于解决了这个问题，但我仍然无法弄清楚实际的 issue.What 我所做的是我编写了一个单独的函数来获取多行文本。它就像一个魅力

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;

}
