布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/recycler_launcher_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical">
    <androidx.wear.widget.CircularProgressLayout
        android:id="@+id/circular_progress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:padding="4dp"
        app:backgroundColor="@color/blue_a400"
        app:colorSchemeColors="@color/red_a200"
        app:strokeWidth="4dp">
        <ImageView
            android:id="@+id/image_view"
            android:src="@drawable/a"
            android:layout_width="40dp"
            android:layout_height="40dp" />
    </androidx.wear.widget.CircularProgressLayout>
</RelativeLayout>

import android.os.Bundle;

    }

    @Override

        if (view.equals(circularProgress)) {
            // User canceled, abort the action
            circularProgress.stopTimer();
        }
    }

    private void initView() {
        mImageView = (ImageView) findViewById(R.id.image_view);
        circularProgress = (CircularProgressLayout) findViewById(R.id.circular_progress);
        mRecyclerLauncherView = (RelativeLayout) findViewById(R.id.recycler_launcher_view);
