copied!<p>Im new at android development. I'm developing an app where first of all, I have a main activity where I must turn On/Off the bluetooth, make it discoverable, search devices and connect to them. </p> <p>After this, I go to other activity where I have a text view with a edittext and a send button, where I can write something and send it. </p> <p>I've got working all the bluetooth enabling/disabling stuff, but now I need to connect to new found devices and then enter to the chat type activity and send. </p> <p>I now this is pretty much work, but it would be great if you can give me an example of how can I do this. This is the code i have:</p> <pre><code>public class BTActivity extends Activity { // Intent request codes private static final int REQUEST_DISCOVERABLE_BT = 0; private static final int REQUEST_CONNECT_DEVICE = 1; private static final int REQUEST_ENABLE_BT = 2; // Debugging private static final String TAG = "BluetoothChat"; private static final boolean D = true; // Name of the connected device public static String mConnectedDeviceName = null; // Array adapter for device list private ArrayAdapter<String> mArrayAdapter; // Local Bluetooth adapter private BluetoothAdapter mBluetoothAdapter = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Button button1 = (Button) findViewById(R.id.boton1); final Button button2 = (Button) findViewById(R.id.boton2); final Button button3 = (Button) findViewById(R.id.boton3); final Button button4 = (Button) findViewById(R.id.boton4); final Button button5 = (Button) findViewById(R.id.boton5); button5.setOnClickListener(new OnClickListener() { public void onClick(View view) { lanzarComunicacion (null); } }); mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); if (mBluetoothAdapter == null) { Toast.makeText(this, "Bluetooth is not available", Toast.LENGTH_LONG).show(); finish(); return; } button3.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if (!mBluetoothAdapter.isEnabled()) { Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT); } } }); button2.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { //LLAMA A LA DIALOG ACTIVITY PARA VISUALIZAR LOS DISPOSITIVOS LanzarBusqueda(null); } }); button1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if (!mBluetoothAdapter.isDiscovering()) { Context context = getApplicationContext(); CharSequence text = "MAKING YOUR DEVICE DISCOVERABLE"; int duration = Toast.LENGTH_SHORT; Toast toast = Toast.makeText(context, text, duration); toast.show(); Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300); startActivity(discoverableIntent); } } }); button4.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { mBluetoothAdapter.disable(); Context context = getApplicationContext(); CharSequence text = "TURNING_OFF BLUETOOTH"; int duration = Toast.LENGTH_LONG; Toast toast = Toast.makeText(context, text, 15); toast.show(); } }); } public void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case REQUEST_CONNECT_DEVICE: if (resultCode == Activity.RESULT_OK) { connectDevice(data); } } } private void connectDevice(Intent data) { String address = data.getExtras().getString(DeviceListDialog.EXTRA_DEVICE_ADDRESS); BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address); BTCommunication.mChatService.connect(device); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.bt, menu); return true; } public void lanzarComunicacion (View view) { Intent i = new Intent(this, BTCommunication.class); startActivity(i); } public void LanzarBusqueda (View view) { Intent i = new Intent(this, DeviceListDialog.class); startActivity(i); } </code></pre> <p>}</p>
