Android蓝牙连接设备

Android蓝牙连接设备,android,textview,android-arrayadapter,Android,Textview,Android Arrayadapter,我不知道如何通过以下代码将我的绑定设备列入列表: bt_scan.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices(); // If there are paired de

我不知道如何通过以下代码将我的绑定设备列入列表:

bt_scan.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
            // If there are paired devices
            if (pairedDevices.size() > 0) {
                // Loop through paired devices
                for (BluetoothDevice device : pairedDevices) {
                    // Add the name and address to an array adapter to show in a ListView
                    mArrayAdapter.add(device.getName() + "\n" + device.getAddress());
                }
            }

                                                        }});}
bt_scan.setOnClickListener(新视图.OnClickListener(){
公共void onClick(视图v){
设置pairedDevices=mBluetoothAdapter.getBondedDevices();
//如果有配对的设备
如果(pairedDevices.size()>0){
//循环通过配对设备
用于(蓝牙设备:pairedDevices){
//将名称和地址添加到要在列表视图中显示的阵列适配器
mArrayAdapter.add(device.getName()+“\n”+device.getAddress());
}
}
}});}
我不知道如何在文本视图或列表视图中获得相同的布局,如果可能的话,甚至在另一个布局中。 我想连接一个找到的设备,但那完全是另一回事

(如果有帮助,下面是我的完整代码:)


非常感谢

查看Android SDK中提供的蓝牙聊天应用程序,它提供了一种显示当前配对手机的干净方式


它还提供了一个BluetoothChatService类,您可以轻松地调整该类以连接找到的设备。

是的,我同意Vishwa的观点,Bluetooth聊天应用程序非常有用,我也做过类似的开发(像您一样),这是我的代码

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView android:id="@+id/title_new_devices"
        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:background="#666" android:textColor="#fff"
        android:paddingLeft="5dp" />
    <ListView android:id="@+id/new_devices" android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

代码将搜索活动的蓝牙设备并将其显示在listView中。

如果只想将arrayAdapter结果显示在listView中,只需将arrayAdapter设置为listView控件即可。我做了一个简单的视频,介绍如何通过适配器将项目添加到列表视图中,您可以或多或少地跳到第4分钟。
