在onReceive()中,我想创建一个新的Intent并启动一个新的Activity。活动结束后,我想回到我离开活动的同一行。我知道我不能使用BroadcastReceiver类来实现这一目标。怎么能实现这一目标?下面是onReceive()代码:
final BroadcastReceiver mPairingRequestRecevier = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(intent.getAction()))
{
final BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
int type = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_VARIANT, BluetoothDevice.ERROR);
if (type == BluetoothDevice.PAIRING_VARIANT_PIN)
{
abortBroadcast();
String passkey="hey";
Intent passkeyIntent = new Intent(context.getApplicationContext(),TestActivity.class);
passkeyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
passkeyIntent.putExtra("passkey",passkey);
context.startActivity(passkeyIntent);
Log.d("after returning...",passkey);
}
else
{
Log.d("Unexpected pairingtype:" , type+"");
}
}
}
};
任何可以实现这一目标的想法都会受到赞赏。

您可以使用startActivityFor结果而不是startActivity来启动活动。使其执行某项任务并将结果返回到上一个活动 看看这个:How to manage `startActivityForResult` on Android?
