我想要启用/禁用安卓手机的GSM连接,需要根据需要禁用/启用电话和短信。我该如何做到这一点?
编辑:这个解决方案也会关闭wifi、蓝牙等功能...
如果你只想关闭无线电,我认为它与这个问题有关:http://code.google.com/p/android/issues/detail?id=1065我非常悲观,不过好奇其他答案。
请查看博客文章Android: Controlling Airplane Mode。
// 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);
isEnabled
表示是否启用飞行模式。
但请不要忘记,您需要WRITE_SETTINGS权限才能执行此操作。
/* 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
android.permission.WRITE_SETTINGS
,对于蓝牙则需要 android.permission.BLUETOOTH_ADMIN
。对于NFC,您可能需要使用 android.permission.NFC
。
