public class connection extends AppCompatActivity {
Button b1,b2,b3,b4;
private BluetoothAdapter BA;
private Set<BluetoothDevice>pairedDevices;
ListView lv;
[USER=1021285]@override[/USER]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_connection);
b1 = (Button)findViewById(R.id.button);
b2=(Button)findViewById(R.id.button2);
b3=(Button)findViewById(R.id.button3);
b4=(Button)findViewById(R.id.button4);
BA = BluetoothAdapter.getDefaultAdapter();
lv = (ListView)findViewById(R.id.listView);
}
public void on(View v){
if (!BA.isEnabled()) {
Intent turnOn = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(turnOn, 0);
Toast.makeText(getApplicationContext(), "Turned on",Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "Already on", Toast.LENGTH_LONG).show();
}
}
public void off(View v){
if (BA.disable());
Toast.makeText(getApplicationContext(), "Turned off" ,Toast.LENGTH_LONG).show();
}
public void visible(View v){
Intent getVisible = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
startActivityForResult(getVisible, 0);
}
public void list(View v){
pairedDevices = BA.getBondedDevices();
ArrayList list = new ArrayList();
for(BluetoothDevice bt : pairedDevices) list.add(bt.getName());
Toast.makeText(getApplicationContext(), "Showing Paired Devices",Toast.LENGTH_SHORT).show();
final ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1, list);
lv.setAdapter(adapter);
