如何使Providerinfo感到表面并发症

Question

我找到了以下内容：https：//developer.android.com/reference/Randroid/support/support/wearable/complications/providerinforetriever.html

我尝试实现的：

Executor executor = new Executor() {
    @Override
    public void execute(@NonNull Runnable command) {
    }
};
ProviderInfoRetriever.OnProviderInfoReceivedCallback callback = new ProviderInfoRetriever.OnProviderInfoReceivedCallback() {
    @Override
    public void onProviderInfoReceived(int i, @Nullable ComplicationProviderInfo complicationProviderInfo) {
        Log.d("MyWatchFace", complicationProviderInfo.providerName);
    }
};
ProviderInfoRetriever providerInfoRetriever = new ProviderInfoRetriever(MyWatchFaceService.this, executor);
providerInfoRetriever.init();
providerInfoRetriever.retrieveProviderInfo(callback,
        new ComponentName(
                getApplicationContext(),
                MyWatchFaceService.class)
        , COMPLICATION_IDS);

可悲的是，我在调试日志中没有看到任何内容：/我在executor或其他事情上做错了什么？

Answer 1

是的，您的Executor做错了什么。这是我的一个看起来像（并且在起作用）：

final Executor executor = new Executor() {
            @Override
            public void execute(@NonNull Runnable r) {
                new Thread(r).start();
            }
        };

对我来说，就像您缺少Thread代码。

似乎我必须使用特定的执行人：

Executor executor = Executors.newSingleThreadExecutor();
ProviderInfoRetriever.OnProviderInfoReceivedCallback callback = new ProviderInfoRetriever.OnProviderInfoReceivedCallback() {
    @Override
    public void onProviderInfoReceived(int i, @Nullable ComplicationProviderInfo complicationProviderInfo) {
        Log.d("MyWatchFace", complicationProviderInfo.providerName);
    }
};
ProviderInfoRetriever providerInfoRetriever = new ProviderInfoRetriever(getApplicationContext(), executor);
providerInfoRetriever.init();
providerInfoRetriever.retrieveProviderInfo(callback,
        new ComponentName(
                getApplicationContext(),
                MyWatchFaceService.class)
        , COMPLICATION_IDS);
