Question

我为表盘构建了一个配置活动。 Android Wear会显示并启动配置活动。

是否可以从配套应用启动配置活动？

我创建了一个活动，但无法传递Android Wear活动似乎在启动配置活动时传递的EXTRA_PEER_ID。

Answer 1

我可以在How to detect if android device is paired with android wear watch的帮助下完成此操作 EXTRA_PEER_ID只是连接的磨损设备的nodeId，可以使用下面的代码检索。

然后，您可以使用Intent.putExtra(WatchFaceCompanion.EXTRA_PEER_ID, nodeId);并通过意图传递ID并启动配置活动。

代码：

private GoogleApiClient client;
private static final long CONNECTION_TIME_OUT_MS = 1000;

public void checkIfWearableConnected() {

    retrieveDeviceNode(new Callback() {
        @Override
        public void success(String nodeId) {
            Toast.makeText(LaunchActivity.this, "There was at least one wearable found", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void failed(String message) {
            Toast.makeText(LaunchActivity.this, "There are no wearables found", Toast.LENGTH_SHORT).show();
        }
    });

}

private GoogleApiClient getGoogleApiClient(Context context) {
    if (client == null)
        client = new GoogleApiClient.Builder(context)
                .addApi(Wearable.API)
                .build();
    return client;
}

private interface Callback {
    void success(final String nodeId);
    void failed(final String message);
}

private void retrieveDeviceNode(final Callback callback) {
    final GoogleApiClient client = getGoogleApiClient(this);
    new Thread(new Runnable() {

        @Override
        public void run() {
            client.blockingConnect(CONNECTION_TIME_OUT_MS, TimeUnit.MILLISECONDS);
            NodeApi.GetConnectedNodesResult result =
                    Wearable.NodeApi.getConnectedNodes(client).await();
            List<Node> nodes = result.getNodes();
            if (nodes.size() > 0) {
                String nodeId = nodes.get(0).getId();
                callback.success(nodeId);
            } else {
                callback.failed("no wearables found");
            }
            client.disconnect();
        }
    }).start();
}

从app开始观看面部配置活动
