Bluetooth経由でメッセージを渡すアプリを開発しています.1つのデバイスから別のデバイスに1つのメッセージを渡したい(デバイスは既にペアリングされています) ペアリングされたデバイスを表示できます.しかし、2つのデバイスを接続する方法がわかりません.誰でもできます従うべき手順を教えてください.2台の電話間の接続を作成する方法は?
public class MainActivity extends Activity {
TextView textview1;
private static final int REQUEST_ENABLE_BT = 1;
BluetoothAdapter btAdapter;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textview1 = (TextView) findViewById(R.id.textView1);
// Getting the Bluetooth adapter
btAdapter = BluetoothAdapter.getDefaultAdapter();
textview1.append("\nAdapter: " + btAdapter);
CheckBluetoothState();
}
/* It is called when an activity completes.*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_ENABLE_BT) {
CheckBluetoothState();
}
}
@Override
protected void onDestroy() {
super.onDestroy();
}
private void CheckBluetoothState() {
// Checks for the Bluetooth support and then makes sure it is turned on
// If it isn't turned on, request to turn it on
// List paired devices
if(btAdapter==null) {
textview1.append("\nBluetooth NOT supported. Aborting.");
return;
} else {
if (btAdapter.isEnabled()) {
textview1.append("\nBluetooth is enabled...");
// Listing paired devices
textview1.append("\nPaired Devices are:");
Set<BluetoothDevice> devices = btAdapter.getBondedDevices();
for (BluetoothDevice device : devices) {
textview1.append("\n Device: " + device.getName() + ", " + device);
}
} else {
//Prompt user to turn on Bluetooth
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
