如何在 android 中禁用/启用蜂窝网络?我需要在短时间内完全禁用它,因为我有 android 4.4+ 飞行模式很难使用。

是否可以编写代码仅禁用蜂窝网络?

控制飞行模式

检查它是否启用:

boolean isEnabled = Settings.System.getInt(
      context.getContentResolver(), 
      Settings.System.AIRPLANE_MODE_ON, 0) == 1;

要切换它:

// toggle airplane mode
Settings.System.putInt(
      context.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);

您可以使用此功能:

/* Toggle airplane mode for 1 of the 4 allowed types
 * type allowed values: cell, wifi, bluetooth, nfc
 */
private void changeRadioComponentEnabled(Context context, String type, boolean radio_component_enabled, boolean reset){     
        // now toggle airplane mode from on to off, or vice versa
        Settings.System.putInt(context.getContentResolver(), Settings.System.AIRPLANE_MODE_ON, radio_component_enabled ? 0 : 1);

        // now change system behavior so that only one component is turned off
        // this also affects the future behavior of the system button for toggling air-plane mode. 
        // to reset it in order to maintain the system behavior, set reset to true, otherwise we lazily make sure mobile voice is always on
        Settings.System.putString(context.getContentResolver(), Settings.System.AIRPLANE_MODE_RADIOS, type); 

        // post an intent to reload so the menu button switches to the new state we set
        Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
        intent.putExtra("state", radio_component_enabled ? false : true);
        context.sendBroadcast(intent);

        // revert to default system behavior or not
        if (reset){ Settings.System.putString(context.getContentResolver(), Settings.System.AIRPLANE_MODE_RADIOS, "cell,bluetooth,wifi,nfc"); }
        // if reset to default is not chosen, always enable mobile cell at  least
        // but only if NOT changing the mobile connection...
        else if (type.indexOf("cell") == 0) { Settings.System.putString(context.getContentResolver(), Settings.System.AIRPLANE_MODE_RADIOS, "cell");}
}//end method

你需要权限android.permission.WRITE_SETTINGS

编辑:我读到这种方法不再可能使用 Android 4.2 及更高版本。但我认为您可以阅读一些有趣的代码:
