I'm trying to scan and discover bluetooth devices and put in in a
clickable ListView. When i use 'extend Activity' without any
ListActivity implementation it works fine. But when I start using any
ListActivity implementation, everything doesnt work. The ListActivity
wouldn't even run. Here is the code (assuming bluetooth is already
running).
-------------------------------------------------------
package com.project;
import java.util.ArrayList;
import android.app.ListActivity;
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothDevice;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import android.util.Log;
public class DetectBluetoothDevices extends ListActivity {
private static final String LOG_TAG = "selina";
ListView listDevicesFound;
BluetoothAdapter bluetoothAdapter;
ArrayAdapter<String> btArrayAdapter;
ArrayList<String> al;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bt_devices_list);
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
al = new ArrayList<String>();
al.clear();
bluetoothAdapter.startDiscovery();
registerReceiver(mReceiver, new
IntentFilter(BluetoothDevice.ACTION_FOUND));
setListAdapter(new ArrayAdapter<String>(this,
R.layout.bt_devices_list, al));
listDevicesFound = (ListView)findViewById(R.id.devicesfound);
listDevicesFound.setTextFilterEnabled(true);
listDevicesFound.setOnItemClickListener(new
OnItemClickListener()
{
public void onItemClick (AdapterView<?> parent, View
view,
int position, long id){
Toast.makeText(getApplicationContext(),
((TextView)
view).getText(),
Toast.LENGTH_SHORT).show();
}
});
}
private final BroadcastReceiver mReceiver = new BroadcastReceiver(){
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String action = intent.getAction();
if(BluetoothDevice.ACTION_FOUND.equals(action)) {
BluetoothDevice device =
intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
al.add(device.getName() + "~" + device.getAddress());
Log.v(LOG_TAG, "device name+address: " +
device.getName() + " ~
" + device.getAddress());
Log.v(LOG_TAG, "arrayList: " + al);
}
}
};
}
