我做了一个简单的android Activity ,因为我有一个加号按钮和一个减号按钮,当我单击加号按钮时,带有一些EditTexts的 View (行)将被膨胀到LinearLayout中,点击添加按钮的次数,所以我成功完成了,现在我想获取每个 EditText
值,但是我搜索了很多并且卡在了这里,所以请帮助我,我的代码如下:

代码:
//code to adding layout on buttonClick
case R.id.iv_add:
LayoutInflater layoutInflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View addView = layoutInflater.inflate(R.layout.raw_descs, null);

calculateInvoice();
if (cnt >= 0) {
cnt = cnt - 1;
}
}

cnt = cnt + 1;
listitems.setTag(cnt);
listitems.addView(addView);
calculateInvoice();
break;
private void calculateInvoice() {
double QuantyInt = 1;
double PriceInt = 0;

TextWatcher textwatcher = new TextWatcher() {
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
calculateInvoice();
}
};
这样我正在 inflated layout ,请帮助我如何从每个膨胀的布局中获取 edittexts 值?
最佳答案
点击按钮时,添加addView
到全局ArrayList<ViewGroup> listOfViewGroups
.
编辑:根据您在评论中提供给我的信息,这是您必须要做的(我不能说得比这更清楚)。编写以下方法:
public double getTotal() {
double total = 0;
//get each ViewGroup
for(int i = 0; i < listOfViewGroups.size(); i++) {
ViewGroup vg = listOfViewGroups.get(i);
//get each EditText containing the amount
EditText e = (EditText) v.findViewById(R.id.et_amt);
//get the string entered in the EditText
String str = e.getText().toString();
//change to a double
double amount = Double.parseDouble(str);
//Add to total
total = total + amount;
}
return total;
}
当您准备好添加所有值时,您必须调用该方法。我不能告诉你什么时候你必须调用它,因为只有你知道,我不知道你什么时候想调用。
调用该方法后,将返回的 double 设置为 TextView
的文本这将显示总数。例如,
tv_total.setText(""+getTotal());
(我假设您的 TextView
显示为 tv_total
。
