    int count=0;
    for(SaleReportModel model:Detailist.getReportItems()){
        TableRow headerRow= new TableRow(getActivity());
        headerRow.removeAllViews();

        //Error Caused here in this line

        headerRow.addView(getTextView(model.getPrdcode(), false,count*4),count);
        headerRow.addView(getTextView(model.getSubtype(), false,count*4+1),count);
        headerRow.addView(getTextView(""+model.getDispatchQty(), false,count*4+2),count);
        headerRow.addView(getTextView(""+model.getDispatchvalue(), false,count*4+3),count);
        reportLayout.addView(headerRow,new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT));
        count+=1;
    }
}
public TextView getTextView(String data,boolean isHeader,int id){
    TextView textView= new TextView(getActivity());
    textView.setLayoutParams( new LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT));
    textView.setText(data);
    textView.setId(id);
    textView.setGravity(Gravity.CENTER);
    //textView.setTextColor(Color.BLACK);
    return mDateFrom;

}

请帮忙。

但愿这引起TableLayout父所以这里查看XML。

May it caused by parent of TableLayout so view xml here.

<ScrollView 

android:id="@+id/layoutReport" 
android:layout_height="match_parent"         
android:scrollbars="horizontal|vertical" 
android:layout_width="match_parent"     
android:layout_marginTop="5dip"     
android:scrollbarStyle="outsideInset"
android:fillViewport="true"> 

<HorizontalScrollView 
    android:id="@+id/horizontalView" 
    android:layout_height="wrap_content"     
    android:scrollbars="horizontal|vertical" 
    android:layout_width="wrap_content"     
    android:layout_marginTop="5dip">

    <TableLayout
        android:id="@+id/tlGridTable"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
</TableLayout>
</HorizontalScrollView>

先谢谢了。

推荐答案

在方法 getTextView ，你回来 mDateForm 而不是的TextView 。
由于 mDateForm 已经有一个父视图，你得到一个例外。
正确实施应该是这样的：

In the method getTextView, you're returning mDateForm instead of textView. Since mDateForm already has a parent view, you're getting an Exception. Correct implementation should be like this:

public TextView getTextView(String data,boolean isHeader,int id){
    TextView textView= new TextView(getActivity());
    textView.setLayoutParams( new  LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT));
    textView.setText(data);
    textView.setId(id);
    textView.setGravity(Gravity.CENTER);
    //textView.setTextColor(Color.BLACK);
    return textView;

}
