将设备地址发送到Android中的ConnectThread(蓝牙设备设备) - 蓝牙
问题描述:
我有一个名为scan的按钮,它扫描可用的蓝牙设备并制作列表视图。 当我按下该设备列表中的某个设备时,'调用ConnectThread(BluetoothDevice设备),但如何将单击的设备地址发送到this.'m使用下面的代码。在这能够获取名称,但如何获得地址。将设备地址发送到Android中的ConnectThread(蓝牙设备设备) - 蓝牙
ListView lv = getListView();
// listening to single list item on click
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
mBluetoothAdapter.cancelDiscovery();
// Toast.makeText(getApplicationContext(), "clicked device", 2).show();
String address = mArrayAdapter.get(position);
device = mBluetoothAdapter.getRemoteDevice(address);
new ConnectThread(device);
}
});
ConnectThread代码:
private class ConnectThread extends Thread {
private final BluetoothSocket mmSocket;
private final BluetoothDevice mmDevice;
public ConnectThread(BluetoothDevice device) {
// Use a temporary object that is later assigned to mmSocket,
// because mmSocket is final
BluetoothSocket tmp = null;
mmDevice = device;
Toast.makeText(getApplicationContext(), "device: " + device, 2).show();
// Get a BluetoothSocket to connect with the given BluetoothDevice
try {
// MY_UUID is the app's UUID string, also used by the server code
tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) { }
mmSocket = tmp;
}
public void run() {
// Cancel discovery because it will slow down the connection
mBluetoothAdapter.cancelDiscovery();
try {
// Connect the device through the socket. This will block
// until it succeeds or throws an exception
mmSocket.connect();
} catch (IOException connectException) {
// Unable to connect; close the socket and get out
try {
mmSocket.close();
} catch (IOException closeException) { }
return;
}
// Do work to manage the connection (in a separate thread)
// manageConnectedSocket(mmSocket);
}
/** Will cancel an in-progress connection, and close the socket */
public void cancel() {
try {
mmSocket.close();
} catch (IOException e) { }
}
}
答
我找到答案了这个问题。当我在列表视图中单击项目时使用下面的代码。
ListView lv = getListView();
// listening to single list item on click
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
mBluetoothAdapter.cancelDiscovery();
String info = mArrayAdapter.get(position);
String address = info.substring(info.length() - 17);
device = mBluetoothAdapter.getRemoteDevice(address);
new ConnectThread(device);
}
});
