java - 由 1st Spinner 创建的 2nd Spinner 应该更新 textview
问题描述
第一个微调器根据所选项目添加第二个微调器的数组列表。无论选择第一个 Spinner，文本视图始终更新到第二个 Spinner 的第一项，但是当从第二个 Spinner 中选择另一个项目（例如第二个项目）时它不会更新，变量“emailname”和“emailto”也是如此" 即使“emailto”变量在其余活动中具有相同的值。“emailname”证明它不是另一个“emailto”，因为它不会根据来自 2nd Spinner 的其余项目更改值。
活动有效，但价值没有改变。
我尝试在 if 语句的外部/内部添加 runOnUiThread，使 t1.setValue 在外部单独使用 runOnUiThread。没用。
我添加了一个 s2.setOnItemSelectedListener(this); 它使第二个微调器的选定项目始终粘在第一个项目上。

解决方案
看起来您只为第一个微调器设置了 OnItemSelectedListener。您还必须为第二个微调器设置 OnItemSelectedListener。
s1.setOnItemSelectedListener(this);
s2.setOnItemSelectedListener(this);
之后，您必须使用微调器 ID 处理 OnItemSelectedListener。
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (parent.getId() == R.id.spinnerdepartment) {
//Do whatever you want when item selected from the first spinner
} else {
//Do whatever you want when item selected from the second spinner
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
除了实现 OnItemSelectedListener 之外，您还可以像下面这样设置 OnItemSelectedListener，而无需为您的类实现 OnItemSelectedListener：
s1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
s2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
您还可以对情况使用相同的代码（例如设置适配器等）。我建议对相同代码使用方法并在方法中处理变体。您的代码看起来会更干净，并且易于阅读和处理。
