我正在尝试使用Wifi Direct连接两台设备,但我想以编程方式实现,而不是由用户启动。
为此,我必须更改Device的WifiDirect名称,如下图所示:
现在使用以下方法发现对等方:
wifiP2pManager.discoverPeers(channel,
new WifiP2pManager.ActionListener() {
@Override
public void onSuccess() {
Log.d(TAG, "onSuccess");
}
@Override
public void onFailure(int reason) {
Log.d(TAG, "onFailure");
}
});
通过以下代码连接到特定对等方:
public static void connectPeer(WifiP2pDevice device,
WifiP2pManager manager, Channel channel, final Handler handler) {
WifiP2pConfig config = new WifiP2pConfig();
config.groupOwnerIntent = 15;
config.deviceAddress = device.deviceAddress;
config.wps.setup = WpsInfo.PBC;
manager.connect(channel, config, new ActionListener() {
@Override
public void onSuccess() {
}
@Override
public void onFailure(int reason) {
}
});
}
但我不知道如何更改Wi-Fi Direct的设备名称?
答案 0 :(得分:5)
这对我有用,即使我不建议使用反射来访问WifiP2pManager中的隐藏API。
public void setDeviceName(String devName) {
try {
Class[] paramTypes = new Class[3];
paramTypes[0] = Channel.class;
paramTypes[1] = String.class;
paramTypes[2] = ActionListener.class;
Method setDeviceName = manager.getClass().getMethod(
"setDeviceName", paramTypes);
setDeviceName.setAccessible(true);
Object arglist[] = new Object[3];
arglist[0] = channel;
arglist[1] = devName;
arglist[2] = new ActionListener() {
@Override
public void onSuccess() {
LOG.debug("setDeviceName succeeded");
}
@Override
public void onFailure(int reason) {
LOG.debug("setDeviceName failed");
}
};
setDeviceName.invoke(manager, arglist);
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
