谁能告诉我如何通过在Android中单击按钮以编程方式将手机置于飞行模式?
See the blog article http://dustinbreese.blogspot.in/2009/04/andoid-controlling-airplane-mode.html ,
Works only upto API 16
// 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);
where isEnabled is whether airplane mode is enabled or not.
try this to put your phone on airplane mode.
// read the airplane mode setting
boolean isEnabled = Settings.System.getInt(
getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, 0) == 1;
// toggle airplane mode
Settings.System.putInt(
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);
Also make sure you have the WRITE_SETTINGS permission
this code to make phone silent
AudioManager am = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
there is also vibrate mode and normal mode
am.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
