如何使用Android UiAutomation.injectInputEvent注入click事件

Question

我在我的应用程序中自动测试流程,我在那里安装了设备管理员.要激活大多数设备上的设备管理员(我们假设我没有一些企业API可以让我像三星提供的那样),系统会向用户显示弹出窗口,然后用户必须单击"激活"按钮.

我正在使用Robotium和Android JUnit来推动我的测试.在正常的测试案例中,人们只能与被测试的应用程序和流程进行交互,而不能与出现的任何系统活动进行交互.

该UiAutomation声称让你与利用其他应用程序进行交互访问性框架,然后让一个注入任意输入事件.

所以 - 这就是我要做的事情:

public class AbcTests extends ActivityInstrumentationTestCase2<AbcActivity> {

    private Solo mSolo

    @Override
    public void setUp() {
        mSolo = new Solo(getInstrumentation(), getActivity());

    }

    ...

    public void testAbc(){

        final UiAutomation automation = getInstrumentation().getUiAutomation();         

        MotionEvent motionDown = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), KeyEvent.ACTION_DOWN,
                100,  100, 0);

        // This line was added in to give a complete solution
        motionDown.setSource(InputDevice.SOURCE_TOUCHSCREEN);

        automation.injectInputEvent(motionDown, true)
        MotionEvent motionUp = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), KeyEvent.ACTION_UP,
                100, 100, 0);

        // This line was added in to give a complete solution
        motionUp.setSource(InputDevice.SOURCE_TOUCHSCREEN);

        automation.injectInputEvent(motionUp, true)
        motionUp.recycle();
        motionDown.recycle();
     }

 }

运行此测试时,系统弹出"激活"设备管理员处于活动状态,我只想单击屏幕.为了解决这个问题的目的,我已经将100,100硬编码为点击位置,但实际上我会点击屏幕的右下角,这样我就可以点击按钮了.

我没有在屏幕上发生任何点击事件.有任何人对此有经验吗？有什么选择可以做我想做的事吗？根据我的理解,很少有工具可以做到这一点.

谢谢.

更新setSource为正确答案 添加

Answer 1

终于搞清楚了.我将MotionEvents与我点击按钮时调度的两个事件进行了比较,唯一的区别是源.所以,我在两个motionEvents上设置了源码并且它有效.

....
motionDown.setSource(InputDevice.SOURCE_TOUCHSCREEN);
....
motionUp.setSource(InputDevice.SOURCE_TOUCHSCREEN);

这是该方法的完整版本
