【问题描述】：

Developer.android 说：

void setDefaultSystemComplicationProvider (int watchFaceComplicationId, int systemProvider, int 类型）

但对我不起作用。

【问题讨论】：

你能解释一下这个对你“不起作用”的原因吗？

【解决方案1】：

作为一名初级 Android 开发人员，并且缺乏可用于 Wear OS 平台的社区支持和教程，我一直在努力在默认情况下设置 Wear OS 的复杂性。通过对我的代码进行一些调整，我以某种方式设法使该方法对我有用。我想分享它可能对谁有帮助。这是我用过的方法：

private void initializeComplications() {
    Log.d("complication", "initializeComplications()");

    mActiveComplicationDataSparseArray = new SparseArray<>(COMPLICATION_IDS.length);

    ComplicationDrawable leftComplicationDrawable =
            (ComplicationDrawable) getDrawable(R.drawable.custom_complication_styles);
    leftComplicationDrawable.setContext(getApplicationContext());

    ComplicationDrawable rightComplicationDrawable =
            (ComplicationDrawable) getDrawable(R.drawable.custom_complication_styles);
    rightComplicationDrawable.setContext(getApplicationContext());

    ComplicationDrawable topComplicationDrawable =
            (ComplicationDrawable) getDrawable(R.drawable.custom_complication_styles);
    topComplicationDrawable.setContext(getApplicationContext());

    mComplicationDrawableSparseArray = new SparseArray<>(COMPLICATION_IDS.length);
    mComplicationDrawableSparseArray.put(LEFT_COMPLICATION_ID, leftComplicationDrawable);
    mComplicationDrawableSparseArray.put(RIGHT_COMPLICATION_ID, rightComplicationDrawable);
    mComplicationDrawableSparseArray.put(TOP_COMPLICATION_ID, topComplicationDrawable);

    // Set default complication
    // This time we don't create a setting screen so we need to set it here
    setDefaultSystemComplicationProvider (
            LEFT_COMPLICATION_ID,
            SystemProviders.STEP_COUNT,
            ComplicationData.TYPE_SHORT_TEXT);

    setDefaultSystemComplicationProvider (
            RIGHT_COMPLICATION_ID,
            SystemProviders.WATCH_BATTERY,
            ComplicationData.TYPE_SHORT_TEXT);

    setDefaultSystemComplicationProvider (
            TOP_COMPLICATION_ID,
            SystemProviders.DATE,
            ComplicationData.TYPE_SHORT_TEXT);

    setActiveComplications(COMPLICATION_IDS);
}

最后我把它叫进来了：

public void onCreate(SurfaceHolder holder) {

    setWatchFaceStyle(new WatchFaceStyle.Builder(DigitalPrayerTimes.this)
            .setAcceptsTapEvents(true)
            .build());

    // TODO: Step 2, intro 3
    initializeComplications();
}
