Android Spinner: Get Selected Value

To obtain the selected value of a Spinner in Android, you can achieve it through the following steps:

1. First, define the Spinner component in the XML layout file and set its data source (ArrayAdapter or CursorAdapter) and selected listener (OnItemSelectedListener).

<Spinner
    android:id="@+id/spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:entries="@array/options"
    android:onItemSelectedListener="onItemSelected" />

1. Write the onItemSelected method in Activity or Fragment to retrieve the selected value.

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    String selectedValue = parent.getItemAtPosition(position).toString();
    // 处理选中的值
}

In this method, we first retrieve the value of the selected item using the getItemAtPosition method, then convert it to a string and perform the necessary processing.

The above is the method to retrieve the selected value from the dropdown box in Android, hope it helps you.
