我正在尝试将微调项等于设置为特定整数。我正在使用 onItemSelected 来尝试完成此操作，但问题是，我需要为选中项目设置的整数使用整数在同一行中的另一个 EditText 乘以。混淆了一点，我尝试多次的行中的所有 EditTexts ，引用到列表然后< strong>迭代以便我可以将它们全部添加起来。如何将每个 EditText 与选定的微调器项目（具有 Int值）到乘以由选择的微调器项目？这就是我到目前为止所拥有的...... 对不起！＃/ strong>

循环访问适配器，查找要匹配的值。跟踪循环的索引。找到匹配项后，将微调器的selectedItem设置为该索引。

这看起来比应该使用表布局更难。如果您的所有行都相似并且对您的设计没有任何不利影响，那么您可能会考虑使用listview。那么你可以简单地通过它们的位置引用同一行上的东西 - 方便地作为参数提供。
但是既然你有这样的话，你可以在arraylist中获得所选微调器项的索引。然后你可以参考EditText arraylist。在我的头脑中，我想你对选定的微调器项目setTag()作为标签。然后你循环查找标签并做一些事情，如果它存在。这就是我想出的。请注意，我将onitemselected方法更改为返回double的方法，因为我发现这对于此类任务更有用：
private double calcGradeValue (int pos) {
if (pos == 0){
//A+
gradeValue = 4.0;
} else if (pos == 1){
//A
gradeValue = 4.0;
} else if (pos == 2){
//A-
gradeValue = 3.7;
} else if (pos == 3){
//B+
gradeValue = 3.3;
} else if (pos == 4){
//B
gradeValue = 3.0;
} else if (pos == 5){
//B-
gradeValue = 2.7;
} else if (pos == 6){
//C+
gradeValue = 2.3;
} else if (pos == 7){
//C
gradeValue = 2.0;
} else if (pos == 8){
//C-
gradeValue = 1.7;
} else if (pos == 9){
//D+
gradeValue = 1.3;
} else if (pos == 10){
//D
gradeValue = 1.0;
} else if (pos == 11){
//D-
gradeValue = 0.7;
} else if (pos == 12){
//F
gradeValue = 0.0;
}
return gradeValue;

public void spinnerLoop() {
for(int i = 0; i < allSp.size(); i++) {
if (allSp.get(i).getTag().toString() == "TAGGED!") {
double gradeValue = calcGradeValue(allSp.get(i).getSelectedItemPosition());
double calculation = (gradeValue) * (Integer.parseInt(allEd.get(i).getText().toString()));
// do something with your calculation double
}
}
