@RunWith(AndroidJUnit4.class)
public class MKATest {
    Instrumentation minstrument;
    UiDevice Device;
    @Before
    public void setUp(){
        minstrument= InstrumentationRegistry.getInstrumentation();
        Device=UiDevice.getInstance(minstrument);
    }

    @Test
    public void se(){
        UiObject2 list = Device.findObject(By.clazz("android.widget.LinearLayout"));
        for (UiObject2 child : list.getChildren()) {
            child.getVisibleBounds().contains(118,429,143,470);
            if (!child.getClassName().equals("android.widget.CompoundButton")) {
                continue;
            }
            child.click();
        }

    }
}
