我想启用飞行模式,但如果我启用飞行模式,我不能够使用蓝牙,WiFi。我的目的是限制只有接听电话和短信有关的东西。启用飞行模式与禁用WiFi和蓝牙在Android

我试过以下,但它不工作;

Settings.System.putString(getContentResolver(), 
      Settings.System.AIRPLANE_MODE_RADIOS, "cell,bluetooth"); 

任何一个可以帮我在这

至于IM知道飞行模式将覆盖设置为禁用所有无线通信的选择。

如果您只想禁用部件,则必须单独完成,而不是通过飞行模式。

为您希望终止的每部分通信尝试一种方法。

在我的手机上(股票HTC Desire 2.2),WiFi在飞行模式下仍然可以使用,但蓝牙并不是。 – Joubarc

试试这个。我无法保证它能在所有设备上正常工作。

private ITelephony getTelephonyService() { 
    try { 
     TelephonyManager oTelephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE); 
     Method mGetITelephony = oTelephonyManager.getClass().getDeclaredMethod("getITelephony", new Class[] {}); 
     mGetITelephony.setAccessible(true); 
     return (ITelephony) mGetITelephony.invoke(oTelephonyManager, new Object[] {}); 
    } catch (Exception e) { 
     return null; 
    } 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    try { 
     boolean retval = getTelephonyService().setRadio(false); 
     Log.v("Radio", "SetRadio : " + retval); 
    } catch (Exception e) { 
     Log.v("Radio", Log.getStackTraceString(e)); 
    } 
} 

您还需要ITelephony.aidl文件。你的项目的src文件夹下有以下内容创建一个包com.android.internal.telephony并在其中创建一个文件ITelephony.aidl

这些无线命令需要MODIFY_PHONE_STATE权限,该权限仅授予系统应用程序。 – mike47

您可以更改当空气平面模式被激活时将被关收音机什么断。如果您在激活飞机模式之前执行此操作,则只能关闭无线电单元。

注意:更改AIRPLANE_MODE_RADIOS会影响切换航空飞机的系统按钮的行为。

下面是一些示例代码,在Android 2.2上测试过。

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

// Change so that only radio cell is turned off 
// NOTE: This affects the behavior of the system button for 
// toggling air-plane mode. You might want to reset it, in order to 
// maintain the system behavior. 
Settings.System.putString(context.getContentResolver, 
    Settings.System.AIRPLANE_MODE_RADIOS, "cell"); 

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

AIRPLANE_MODE_RADIOS似乎在后来的android版本中没有效果。 –
