我最近一直在尝试截取屏幕截图,但是这些文件夹都是在具有 api 级别 8 的 android 模拟器中创建的,但都是徒劳的。我已经提到了下面的代码。
在此代码中,方法 takeScreenShot() 应该创建一个目录并存储图像,同时作为 android junit 测试用例执行,我得到的结果为 100%,但没有创建文件夹,也没有存储屏幕截图。我应该root我的手机以使用它的sd卡吗?
public class NewRobotiumTest extends ActivityInstrumentationTestCase2 {
......

// actual testcase
public void testRecorded() throws Exception {
solo.waitForActivity("com.botskool.DialogBox.DialogBox",
ACTIVITY_WAIT_MILLIS);
solo.clickOnButton("Show Alert");
solo.clickOnButton("Ok");
solo.clickOnButton("Show Yes/No");
takeScreenShot(solo.getViews().get(0), "testRecorded_1316975601089");
solo.sleep(2000);
solo.clickOnButton("Yes");
solo.clickOnButton("Show List");
solo.clickOnScreen(118f, 563f);
}
