我想启用飞行模式但是如果我启用飞行模式我无法使用蓝牙,wifi。我的目的是仅限制接收电话和短信相关的事情。

我尝试了以下内容,但它不起作用;

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

任何人都可以帮助我

您可以更改激活飞机模式时关闭的无线电。如果在激活飞机模式之前执行此操作,则可以仅关闭无线电单元。

注意:更改AIRPLANE_MODE_RADIOS会影响用于切换飞机的系统按钮的行为。

以下是一些示例代码,在Android 2.2上进行了测试。

// 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);

据我所知,飞行模式将涵盖选择禁用所有无线通信的设置。

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。

为您希望终止的每个通信部分尝试一种方法。

试试这个。我无法保证它能在所有设备上正常运行。

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。在项目的src文件夹下创建一个包com.android.internal.telephony,并在其中创建一个文件ITelephony.aidl,其中包含以下内容:

 */
interface ITelephony {
    /**
     * Check to see if the radio is on or not.
     * @return returns true if the radio is on.
     */
    boolean isRadioOn();

    /**
     * Toggles the radio on or off.
     */
    void toggleRadioOnOff();

    /**
     * Set the radio to on or off
     */
    boolean setRadio(boolean turnOn);
}

您有2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

例如,如果您想防止在“飞行”模式下禁用蓝牙, 您可以从airplane_mode_radios

删除蓝牙

并且如果您想防止蓝牙在以前未启用的情况下无法启用(是的,有时在打开和关闭飞行模式时可能会发生这种情况) 因此您可以从airplane_mode_toggleable_radios中删除蓝牙(如果在开启和关闭飞行模式之前启用了蓝牙,则该蓝牙仍然会启用)

使用亚行:

adb shell settings put global airplane_mode_radios 'cell,wifi,nfc,wimax'
adb shell settings put global airplane_mode_toggleable_radios 'wifi,nfc'

以编程方式使用:

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,请重新启动设备
