上回说到，在Android自动化测试时，通过反射机制，我们能获得页面的所有控件。来看一个简单的应用例子：ArrayList views = getAllViews();

for(View view : views)

Log.d("Views On Activity:", view.getClass().getName());

}

这样在LogCat里我们就可以打印出所有的View了：-27 22:24:52.369: D/Views On Activity:(2123): android.widget.LinearLayout

-27 22:24:52.369: D/Views On Activity:(2123): com.android.internal.widget.ActionBarContainer

我们看到这里罗列了所有的控件，有Layout, TextView， Button 等等。而获得了这些控件，对我们有什么用呢？

Yes，有了这些控件，我们就可以执行相应的操作了！

比如：

1、有了Button，我们可以执行Click On Button操作

2、有了TextView，我们就可以得到页面的所有Text，去验证Message或者做Localization Testing

3、同样有了ImageView，我们可以执行Click操作，甚至可以得到页面显示的图片

4、.......

下面分享一些我们项目中用到的关于这些操作的典型片断：

● Click 操作public void clickOnView(int id)

{

View view = solo.getView(id);

if(view != null)

{

solo.clickOnView(view);

}

}
