无法从同一 xml 源将多行加载到 TableLayout

Question

我有 TableLayout，我想从同一文件动态加载行，即 automationrow.xml 实际上是预定义的 table row.Here 是我想要的行复制。

<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"

    android:layout_marginTop="@dimen/activity_vertical_margin"
    android:visibility="visible">

    <android.support.v7.widget.CardView

        card_view:cardCornerRadius="5dp">

        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</TableRow>

我在一个片段和运行以下代码中执行此操作，但它在仅添加一行并出现以下错误后中断

java.lang.IllegalStateException: 指定的child已经有一个parent。您必须先在 child 的 parent 上调用 removeView()。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.controls, container, false);        
    TableLayout Tab =(TableLayout) rootView.findViewById(R.id.table);
    View view = LayoutInflater.from(getActivity()).inflate(R.layout.automationrow, container,false);
    TableRow newr = (TableRow) view.findViewById(R.id.R1);
    for (int i=1;i<=2;i++){
        Tab.addView(newr);
        Log.d("check runs",String.valueOf(i)); //printed only once
        //Tab is the TableLayout
    }
}

Answer 1

试试这个

 for (int i=1;i<=2;i++){

     View view = LayoutInflater.from(getActivity()).inflate(R.layout.automationrow, container,false);
     TableRow newr = (TableRow) view.findViewById(R.id.R1);
     Tab.addView(newr);
     Log.d("check runs",String.valueOf(i)); //printed only once
     //Tab is the TableLayout
}

无法从同一 xml 源将多行加载到 TableLayout
