按钮点击android穿

Question

我用一个小按钮创建了android磨损活动(我的移动应用程序中的活动快捷方式).是否可以将捆绑请求发送到我的主应用程序？

如果是这样,如何实现点击监听器？

谢谢!

这可以使用上面提到的MessageApi来完成:http://developer.android.com/training/wearables/data-layer/messages.html
您需要初始化并连接GoogleApiClient.单击按钮后,您必须获取节点列表并向其发送消息.最后一步是从应用程序的手机部分读取此消息,这可以通过注册正确的WearableListenerService来完成.请参阅下面的示例代码.

应用程序的可穿戴部分:
请在应用程序的可穿戴部分定义此类活动:

public class WearableButtonActivity extends Activity {

    private GoogleApiClient mGoogleApiClient;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.wearable_button_activity);

        mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Wearable.API)
            .build();
        mGoogleApiClient.connect();
    }

    public void onButtonClicked(View target) {
        if (mGoogleApiClient == null)
            return;

        final PendingResult<NodeApi.GetConnectedNodesResult> nodes = Wearable.NodeApi.getConnectedNodes(mGoogleApiClient);
        nodes.setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>() {
            @Override
            public void onResult(NodeApi.GetConnectedNodesResult result) {
                final List<Node> nodes = result.getNodes();
                if (nodes != null) {
                    for (int i=0; i<nodes.size(); i++) {
                        final Node node = nodes.get(i);

                        // You can just send a message
                        Wearable.MessageApi.sendMessage(mGoogleApiClient, node.getId(), "/MESSAGE", null);

                        // or you may want to also check check for a result:
                        // final PendingResult<SendMessageResult> pendingSendMessageResult = Wearable.MessageApi.sendMessage(mGoogleApiClient, node.getId(), "/MESSAGE", null);
                        // pendingSendMessageResult.setResultCallback(new ResultCallback<MessageApi.SendMessageResult>() {
                        //      public void onResult(SendMessageResult sendMessageResult) {
                        //          if (sendMessageResult.getStatus().getStatusCode()==WearableStatusCodes.SUCCESS) {
                        //              // do something is successed
                        //          }
                        //      }
                        // });
                    }
                }
            }
        });
    }
}

并将onButtonClick方法攻击到res/layout/wearable_button_activity.xml文件中的按钮:

<Button android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Click me!"
    android:layout_gravity="center"
    android:onClick="onButtonClicked" />

或者,如果您喜欢这样,只需从代码中设置OnClickListener:

    findViewById(R.id.button).setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            onButtonClicked(v);
        }
    });

应用程序的电话部分:
然后在您的手机清单上声明DataLayerListenerService:

<service android:name=".DataLayerListenerService" >
    <intent-filter>
        <action android:name="com.google.android.gms.wearable.BIND_LISTENER" />
    </intent-filter>
</service>

DataLayerListenerService类:

public class DataLayerListenerService extends WearableListenerService {

    @Override
    public void onMessageReceived(MessageEvent messageEvent) {
        super.onMessageReceived(messageEvent);
        if("/MESSAGE".equals(messageEvent.getPath())) {
            // launch some Activity or do anything you like
        }
    }
}

重要提示:您的应用程序的两个部分都需要具有相同的程序包名称才能相互联系.
