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<View> views = getAllViews(); 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 -27 22:24:52.369: D/Views On Activity:(2123): com.android.internal.widget.ActionBarView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.LinearLayout -27 22:24:52.369: D/Views On Activity:(2123): android.widget.ImageView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.LinearLayout -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): com.android.internal.widget.ActionBarView$HomeView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.ImageView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.ImageView -27 22:24:52.369: D/Views On Activity:(2123): com.android.internal.view.menu.ActionMenuView -27 22:24:52.369: D/Views On Activity:(2123): com.android.internal.widget.ActionBarContextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.FrameLayout -27 22:24:52.369: D/Views On Activity:(2123): android.widget.RelativeLayout -27 22:24:52.369: D/Views On Activity:(2123): android.widget.RelativeLayout -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.ImageView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.ImageView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.RelativeLayout -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.TextView -27 22:24:52.369: D/Views On Activity:(2123): android.widget.Button -27 22:24:52.369: D/Views On Activity:(2123): com.android.internal.policy.impl.PhoneWindow$DecorView |
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); } } |
