如何获取自旋体值?

Spinner mySpinner = (Spinner) findViewById(R.id.your_spinner);
String text = mySpinner.getSelectedItem().toString();

选择某个选项时,微调器应触发“OnItemSelected”事件:

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        Object item = parent.getItemAtPosition(pos);
    }
    public void onNothingSelected(AdapterView<?> parent) {
    }
});

假设这是带有微调器项(即标题)和值的XML:

<resources>
    <string-array name="size_entries">
        <item>Small</item>
        <item>Medium</item>
        <item>Large</item>
    </string-array>

    <string-array name="size_values">
        <item>12</item>
        <item>16</item>
        <item>20</item>
    </string-array>
</resources>

这是你的旋转器:

<Spinner
    android:id="@+id/size_spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:entries="@array/size_entries" />

然后在代码中获取条目:

Spinner spinner = (Spinner) findViewById(R.id.size_spinner);
String size = spinner.getSelectedItem().toString(); // Small, Medium, Large

为了得到这些值:

int spinner_pos = spinner.getSelectedItemPosition();
String[] size_values = getResources().getStringArray(R.array.size_values);
int size = Integer.valueOf(size_values[spinner_pos]); // 12, 16, 20

是的,您可以通过 setOnItemSelectedListener() ,如图所示 here .

View view =(View) getActivity().findViewById(controlId);
Spinner spinner = (Spinner)view.findViewById(R.id.spinner1);
String valToSet = spinner.getSelectedItem().toString();

如果你已经知道物品是 String 我更喜欢:

String itemText = (String) mySpinner.getSelectedItem();

打电话 toString() 关于一个 Object 你知道的是 弦 似乎是一条更迂回的道路,而不仅仅是 对象 到 弦 .
