如何使用 UiAutomator 访问媒体通知控件？

Question

我基本上是从一个 Activity 启动一个前台媒体服务，然后将该 Activity 移动到

Lifecycle.State.DESTROYED

:

@RunWith(AndroidJUnit4.class)
public class MainActivityStateTest extends BaseActivityTestCase {

    protected ActivityScenario<MainActivity> mScenario;

    @Before
    public void setupTest() {
        this.setScenario(this.activityScenarioRule.getScenario());
        this.getScenario().onActivity(activity -> { /* ... */ });
    }

    @Test
    public void testActivityLifecycle() {

        /* Destroy the Activity. */
        this.getScenario().moveToState(Lifecycle.State.DESTROYED);

        /* TODO: Use UiAutomator to click media-controls. */
    }

    @NonNull
    protected ActivityScenario<MainActivity> getScenario() {
        return this.mScenario;
    }

    protected void setScenario(@NonNull ActivityScenario<MainActivity> scenario) {
        this.mScenario = scenario;
    }

    @Override
    public void tearDown() throws Exception {
        this.getScenario().close();
        super.tearDown();
    }
}

如何使用 UiAutomator 访问媒体通知控件？

Answer 1

我编写了一些方法，以便获取媒体服务通知的句柄：

@RunWith(AndroidJUnit4.class)
public class MainActivityStateTest extends BaseActivityTestCase {

    protected UiObject openNotificationPanel() {
        synchronized (this.mDevice) {
            if (this.mDevice.openNotification()) {
                this.mDevice.wait(Until.hasObject(By.pkg("com.android.systemui")), 10000);
                UiObject notificationStackScroller = this.mDevice.findObject(
                        new UiSelector()
                                .packageName("com.android.systemui")
                                .className("android.widget.ScrollView")
                                .resourceId("com.android.systemui:id/notification_stack_scroller")
                );
                assertTrue(notificationStackScroller.exists());
                return notificationStackScroller;
            } else {
                return null;
            }
        }
    }

    protected UiObject getMediaServiceNotification(@NonNull UiObject scrollView) {
        try {
            UiObject item = scrollView
                .getChild(new UiSelector().resourceId("com.android.systemui:id/expanded"))
                .getChild(new UiSelector().resourceId("android:id/notification_media_content"));
            assertTrue(item.exists());
            return item;
        } catch (UiObjectNotFoundException e) {
            Log.e(LOG_TAG,"UiObjectNotFoundException: " + e.getMessage());
            return null;
        }
    }

    protected void clickMediaActionAtIndex(@NonNull UiObject notification, int index) {
        try {

            UiObject mediaActions = notification.getChild(new UiSelector().resourceId("android:id/media_actions"));
            assertTrue(mediaActions.exists());

            UiObject mainColumn = notification.getChild(new UiSelector().resourceId("android:id/notification_main_column"));
            assertTrue(mainColumn.exists());

            UiObject mediaProgress = notification.getChild(new UiSelector().resourceId("android:id/notification_media_progress"));
            assertTrue(mediaProgress.exists());

            if (index < mediaActions.getChildCount()) {
                UiObject mediaAction = mediaActions.getChild(new UiSelector().className("android.widget.ImageButton").index(index));
                assertTrue(mediaAction.exists());
                mediaAction.click();
            }
        } catch (UiObjectNotFoundException e) {
            Log.e(LOG_TAG,"UiObjectNotFoundException: " + e.getMessage());
        }
    }
}

测试用例看起来像这样：

@Test
public void testActivityLifecycle() {

    /* Destroy the Activity. */
    this.getScenario().moveToState(Lifecycle.State.DESTROYED);

    /* Click Media-Notification Action at index 2. */
    UiObject notificationStackScroller = this.openNotificationPanel();
    UiObject mediaNotification = this.getMediaServiceNotification(notificationStackScroller);
    this.clickMediaActionAtIndex(mediaNotification, 2); /* eg. 0: rewind, 2: play/pause */
}
