UiAutomator2.0 - 获取同行控件

问题：

UI测试时，在同一个界面出现相同的属性的控件(如图)，对于这种控件的获取很是无奈。如果直接通过控件id去查找的话总是会返回界面该类型的第一个控件。

解决：

1.UiObject2 中已经给出了解决方法，可以通过 getParent()方法处理。缺点：由于UiObjec2t控件与视图进行绑定，当视图变化后该控件对象就被销毁了。所以多次使用则非常不便利

@Test
public void testCase_Btn(){
       UiObject2 switchBtn = device.findObject(By.text("Automatic 24‑hour format"))
               .getParent().getParent().findObject(By.res("android:id/switch_widget"));
       if(switchBtn.isChecked()){
           switchBtn.click();
       }
       assertTrue("switch btn is open", !switchBtn.isChecked());
}

2.UiObject中通过id + instance 去能查找到控件，但是界面变动的话脚本也得变动，可靠性不强。只能采取折中的方式来获取了。不多说，直接上代码。

UiObject switchBnt3 = device.findObject(new UiSelector().resourceId("android:id/switch_widget").instance(2));

测试类：

@Test
public void testCase_Btn() throws UiObjectNotFoundException {
       UiObject timeFormat = device.findObject(new UiSelector().text("Automatic 24‑hour format"));
       UiObject switchBtn = ControlObj.getUiObject(timeFormat);
       if(switchBtn.isChecked()){
           switchBtn.click();
       }
       assertTrue("switch btn is open", !switchBtn.isChecked());
}
