Question

TextView tvBalAchieve = (TextView) rootView.findViewById(R.id.tvBalAchieve);

我从sqlite数据库中检索了一些数据（那些是整数）并减去它们在文本视图中设置结果，如下所示。

tvBalAchieve.setText(Integer.toString(lstTargetAchieveVal.get(0).getTargetVal() - lstTargetAchieveVal.get(0).getAchievedVal()));

这里lstTargetAchieveVal是一个对象数组列表。这是我的实体类细分。

public class WMTargetExecAchieveSummary {
private int targetVol;
private int targetVal;
private int achievedVol;
private int achievedVal;
private int returnVol;
private int returnVal;
private String updatedOn;

public int getTargetVol() {
    return targetVol;
}

public void setTargetVol(int targetVol) {
    this.targetVol = targetVol;
}

public int getTargetVal() {
    return targetVal;
}

public void setTargetVal(int targetVal) {
    this.targetVal = targetVal;
}

public int getAchievedVol() {
    return achievedVol;
}

public void setAchievedVol(int achievedVol) {
    this.achievedVol = achievedVol;
}

public int getAchievedVal() {
    return achievedVal;
}

public void setAchievedVal(int achievedVal) {
    this.achievedVal = achievedVal;
}

这不会给出任何错误消息。但结果是lstTargetAchieveVal.get(0).getTargetVal().

的值

实际上它不是减法的。我在onCreateView方法（片段内）中执行所有这些操作。任何人都可以非常友好地解释这里发生了什么，我该如何纠正它。

Android：在片段中减去两个整数时出错
