如何在一个Kotlin活动中将共享首选项中的项目添加到两个微调器中

implementation 'androidx.preference:preference-ktx:1.1.1'

<NumberPicker
    android:id="@+id/numberPicker1"
    ... />

<SeekBar
    android:id="@+id/seekBar1"
    ... />

import androidx.preference.PreferenceManager

class MainActivity : AppCompatActivity() {
    private lateinit var numberPicker1: NumberPicker
    private lateinit var seekBar1: SeekBar
    private lateinit var sharedPreferences: SharedPreferences

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // 初始化微调器
        numberPicker1 = findViewById(R.id.numberPicker1)
        seekBar1 = findViewById(R.id.seekBar1)

        // 获取SharedPreferences实例
        sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this)

        // 从共享首选项中读取值，并将其应用于微调器
        val value = sharedPreferences.getInt("key_name", 0)
        numberPicker1.value = value
        seekBar1.progress = value

        // 设置微调器数值改变的监听器
        numberPicker1.setOnValueChangedListener { _, _, newValue ->
            // 将新值保存到共享首选项
            sharedPreferences.edit().putInt("key_name", newValue).apply()
        }

        seekBar1.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
            override fun onProgressChanged(seekBar: SeekBar?, progress: Int, fromUser: Boolean) {
                // 将新值保存到共享首选项
                sharedPreferences.edit().putInt("key_name", progress).apply()
            }

            override fun onStartTrackingTouch(seekBar: SeekBar?) {}
            override fun onStopTrackingTouch(seekBar: SeekBar?) {}
        })
    }
}
