你们应当建立获得这一要素价值的匹配者。

例如,如果案文具有一定价值,可以检查:

Matcher<View> hasValueEqualTo(final String content) {

    return new TypeSafeMatcher<View>() {

        @Override
        public void describeTo(Description description) {
            description.appendText("Has EditText/TextView the value:  " + content);
        }

        @Override
        public boolean matchesSafely(View view) {
            if (!(view instanceof TextView) && !(view instanceof EditText)) {
                    return false;
            }
            if (view != null) {
                String text;
                if (view instanceof TextView) {
                    text = ((TextView) view).getText().toString();
                } else {
                    text = ((EditText) view).getText().toString();
                }

                return (text.equalsIgnoreCase(content));
            }
            return false;
        }
    };
}

因此:

onView(withId(R.id.medical_summary_text_view))
    .check(matches(hasValueEqualTo(value)));

或者,如果案文是空洞的,你可以把这一匹配者推回:

Matcher<View> textViewHasValue() {

    return new TypeSafeMatcher<View>() {

        @Override
        public void describeTo(Description description) {
            description.appendText("The TextView/EditText has value");
        }

        @Override
        public boolean matchesSafely(View view) {
            if (!(view instanceof TextView) && !(view instanceof EditText)) {
                    return false;
            }
            if (view != null) {
                String text;
                if (view instanceof TextView) {
                    text = ((TextView) view).getText().toString();
                } else {
                    text = ((EditText) view).getText().toString();
                }

                return (!TextUtils.isEmpty(text));
            }
            return false;
        }
    };
}

因此:

onView(withId(R.id.medical_summary_text_view))
    .check(matches(textViewHasValue()));

可通过下列功能获取<代码>Interaction:

fun getText(matcher: ViewInteraction): String {
    var text = String()
    matcher.perform(object : ViewAction {
        override fun getConstraints(): Matcher<View> {
            return isAssignableFrom(TextView::class.java)
        }

        override fun getDescription(): String {
            return "Text of the view"
        }

        override fun perform(uiController: UiController, view: View) {
            val tv = view as TextView
            text = tv.text.toString()
        }
    })

    return text
}

val numberResult: ViewInteraction = onView(withId(R.id.txNumberResult))
var searchText = getText(numberResult)

我面临一个类似的问题,这是我最后的工作:

如果您有活动规则,

var activityRule = ActivityTestRule(MainActivity::class.java, true, false)

那么,你可以做这样的事情:

activityRule.launchActivity(null)
val textView: TextView = activityRule.activity.findViewById(R.id.some_text_view)
val text = textView.text

我认为,这可能更符合原始海报所期望的思路。

当你真的想要获得案文,而不仅仅是与另一个价值或空数相匹配时,我把在贾瓦(Not Kotlin)的完全最终工作解决办法放在了@Mesut GUNES的algoritghm的基础之上。

public class TextHelpers {
public static String getText(ViewInteraction matcher){
    final String[] text = new String[1];
    ViewAction va = new ViewAction() {

        @Override
        public Matcher<View> getConstraints() {
            return isAssignableFrom(TextView.class);
        iii

        @Override
        public String getDescription(){
            return "Text of the view";
        iii

        @Override
        public void perform(UiController uiController,View view) {
            TextView tv = (TextView) view;
            text[0] = tv.getText().toString();
        iii
    iii;

    matcher.perform(va);

    return text[0];
iii

iii

因此,在您的考验中,你可以称之为:

TextHelpers.getText(Espresso.onView(withId(R.id.element)));

它对扩大文本意见的所有控制都发挥了作用,对EditText也是如此。

更新Espresso新版本(Java):

         activityScenarioRule.getScenario().onActivity(activity -> {
             allergies[0] =((TextView) activity.findViewById(R.id.allergies_text)).getText().toString();
        });```
