表格行指定的孩子已经有父母。您必须先调用子视图的父级上的removeView（）

Question

无法在表格布局中实际添加表格行。我在这里创建一个视图滚动的水平和垂直方向都与视图类似表有问题将TableRow

/* 
* reportLayout is tablelayout by findViewById 
* i am setting view inside Fragment 
*/ 
public void redrawReport(){ 
    reportLayout.removeAllViews(); 
    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; 

}

请帮助。

可能是由TableLayout的父项造成的，所以在这里查看xml。

<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> 

在此先感谢。

在方法getTextView中，您将返回mDateForm而不是textView。 由于mDateForm已经有父视图，因此您会收到一个异常。 正确实施应该是这样的：

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; 

}
