有没有办法强制开启蓝牙?
到目前为止,我发现的只是这个(使用我正在使用的 estimote sdk):
// Check if device supports Bluetooth Low Energy.
if (!beaconManager.hasBluetooth()) {
Toast.makeText(this, "Device does not have Bluetooth Low Energy", Toast.LENGTH_LONG).show();
return;
}
// If Bluetooth is not enabled, let user enable it.
if (!beaconManager.isBluetoothEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
else {
connectToBlueTooth();
}
然后在onActivityResult
:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_ENABLE_BT) {
if (resultCode == Activity.RESULT_OK) {
connectToBlueTooth();
}
else {
Toast.makeText(this, "Bluetooth not enabled", Toast.LENGTH_LONG).show();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
但这会询问用户是否要打开蓝牙......但是有没有办法在不询问用户的情况下打开它?
而且,如果没有办法做到这一点,我该如何在活动之外使用这种技术?
谢谢
