从微调器setonItemSelectedListener传递值

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

Spinner spinner = findViewById(R.id.spinner);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        String selectedValue = parent.getItemAtPosition(position).toString();
        // 进行相应的操作，如传递给其他组件或进行数据处理等
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {
        // 当没有选择项时的处理
    }
});
