所以我有几个动态创建的tablerows。每个TableRow 都有几个Textviews。我有一个按钮,单击该按钮应该获取表中每个Tablerow 中第二个和第三个textviews 的所有值。我尝试使用下面的代码来做到这一点
mSubmitOrders.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if(mTable.getChildCount()>1){
for(int i = 0; i < mTable.getChildCount(); i++){
TableRow tr = (TableRow)mTable.getChildAt(i);
TextView code = (TextView) tr.getChildAt(1);
TextView quantity = (TextView) tr.getChildAt(2);
String Scode = code.getText().toString();
Log.i("TAG", Scode);
String Squantity = quantity.getText().toString();
Log.i("TAG", Squantity);
}
}
但我得到以下错误(下面的Logcat)。需要协助

已解决:从@zackk 获得帮助后,我最终解决了这个问题:
for(int i = 0; i < mTable.getChildCount(); i++){
TableRow tr = (TableRow) mTable.getChildAt(i);
LinearLayout l1 = (LinearLayout)tr.getChildAt(1);
LinearLayout l2 = (LinearLayout)tr.getChildAt(2);
TextView code = (TextView)l1.getChildAt(0);
sCode = code.getText().toString();
Log.v("Inserted---->", sCode);
codeA[i]=sCode;
TextView quantity = (TextView)l2.getChildAt(0);
sQuantity = quantity.getText().toString();
Log.v("Inserted--->", sQuantity);
quantityA[i]=sQuantity;
}
