Question

我必须使用很多来创建复杂的布局（收据视图）数据。由于可能有x笔费用或付款，因此必须以编程方式完成此视图。

我正在尝试构建可重复使用的布局，我可以将其附加到不同的textview或edittext s并让它们排成一行。

分解它看起来像这样：

归结为2种基本布局：

整个宽度（文本居中的位置）
拆分栏

a）其中一列占据左侧或右侧3/4的视图。

b）并且第二列占据了视野的1/4。

这是我的尝试。但我似乎没有做对。这是我的错误：

指定的孩子已经有父母。你必须调用removeView（）先关于孩子的父母。

有人可以帮忙吗？

private ScrollView mScrollView;
private LinearLayout mLinearLayout;
private ProgressBar mProgressBar;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_payment, container, false);
    mScrollView = (ScrollView) view.findViewById(R.id.svPayment);
    mScrollView.setVisibility(View.GONE);
    mProgressBar = (ProgressBar) view.findViewById(R.id.pbPayment);
    mLinearLayout = (LinearLayout) view.findViewById(R.id.llPayment);
    return view;
}

        //RESUABLE LAYOUT 
        LinearLayout.LayoutParams paramsFull = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        paramsFull.setLayoutDirection(LinearLayout.HORIZONTAL);

        LinearLayout.LayoutParams paramSmall = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        paramSmall.setLayoutDirection(LinearLayout.HORIZONTAL);
        paramSmall.weight = 0.2f;

        LinearLayout.LayoutParams paramLarge = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        paramLarge.setLayoutDirection(LinearLayout.HORIZONTAL);
        paramLarge.weight = 0.8f;


        // HOLDS THE LEFT AND RIGHT COLUMNS
        LinearLayout columnShell = new LinearLayout(getContext());
        columnShell.setLayoutParams(paramsFull);

    //Small column
        LinearLayout columnSmall = new LinearLayout(getContext());
        columnSmall.setLayoutParams(paramSmall);

    //Large column
        LinearLayout columnLarge = new LinearLayout(getContext());
        columnLarge.setLayoutParams(paramLarge);



        //First get rid of all the views, incase of refresh
        mLinearLayout.removeAllViews();


        TextView textView = new TextView(getContext());

        //CUSTOMER
        textView.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);

为什么要将scrollview与linearlayout一起使用，你可能必须使用带有两个textview的listview作为chid，并添加新数据只需将其添加到列表中并通知adpter，你的新数据会自动添加到列表的最后。
