以编程方式在所有API级别上启用飞行模式

Question

如何在点击按钮时以编程方式启用/禁用飞行模式？我试过这个

// read the airplane mode setting
  boolean isEnabled = Settings.System.getInt(
  getContentResolver(), 
  Settings.System.AIRPLANE_MODE_ON, 0) == 1;

// toggle airplane mode
Settings.System.putInt(
  getContentResolver(),
  Settings.System.AIRPLANE_MODE_ON, isEnabled ? 0 : 1);

// Post an intent to reload
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", !isEnabled);
sendBroadcast(intent);

但我得到错误"系统无法解析或不是一个字段",因为它需要API 16或更高版本

<uses-permission android:name="android.permission.WRITE_SETTINGS"/>

有没有任何工作方式这样做适用于所有api级别？

 return Settings.System.getInt(context.getContentResolver(),

 }

 @SuppressLint("NewApi")
 public void airplaneModeOn(View view) {
 try {

 android.provider.Settings.System.putInt(getContentResolver(),

 isAirplaneModeOn(getApplicationContext()) ? 0 : 1);

 Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
 intent.putExtra("state", !isAirplaneModeOn(getApplicationContext()));
 sendBroadcast(intent);
 } catch (Exception e) {
 Toast.makeText(this, "Exception occured during Airplane Mode ON", Toast.LENGTH_LONG)
 .show();
 }
 }
