我想启用飞行模式,但如果我启用飞行模式,我将无法使用蓝牙、WiFi等功能。我的目的是仅限制接收电话和短信相关事项。
我尝试了以下方法,但它们都没有起作用:
Settings.System.putString(getContentResolver(),
Settings.System.AIRPLANE_MODE_RADIOS, "cell,bluetooth");
can any one help me in this

当打开飞行模式时,您可以更改将关闭的无线电。如果在激活飞行模式之前这样做,则可能仅关闭无线电蜂窝。
注意:更改AIRPLANE_MODE_RADIOS会影响系统切换飞行模式按钮的行为。
以下是在Android 2.2上测试过的示例代码。
// 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);
你有两个可以更改的设置数组:
airplane_mode_radios=cell,bluetooth,wifi,nfc,wimax
airplane_mode_toggleable_radios=bluetooth,wifi,nfc
airplane_mode_radios
中移除蓝牙。airplane_mode_toggleable_radios
中移除蓝牙(如果它在飞行模式开启之前已经启用,则仍将被启用)。adb shell settings put global airplane_mode_radios 'cell,wifi,nfc,wimax'
adb shell settings put global airplane_mode_toggleable_radios 'wifi,nfc'
Settings.Global.putString(getContentResolver(), "airplane_mode_radios", "cell,wifi,nfc,wimax");
Settings.Global.putString(getContentResolver(), "airplane_mode_toggleable_radios", "wifi,nfc");
注意:完成后,请重新启动您的设备
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。在您的项目src文件夹下创建一个名为com.android.internal.telephony
的包,并在其中创建一个名为ITelephony.aidl
的文件,其内容如下:
