Android-Espresso: 使用 R.color.xxx 无法检查 textView 文本颜色
Android-Espresso: With R.color.xxx can't check textView text color
这是我的 colors.xml
<color name="color_primary">#29c9b9</color>
这是我的xml
<TextView
android:id="@+id/registerTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/register"
android:textAllCaps="true"
android:textColor="@color/color_primary"/>
所以我想在 TextView 中编写 Espresso 测试检查 android:textColor="@color/color_primary"
所以这是我的测试:
@Test
public void registerTextViewTextColor() {
onView(withId(R.id.registerTextView)).check(matches(withTextColor(Color.parseColor("#29c9b9"))));
}
这里是匹配器:
public static Matcher<View> withTextColor(final int expectedId) {
return new BoundedMatcher<View, TextView>(TextView.class) {
@Override
protected boolean matchesSafely(TextView textView) {
return expectedId == textView.getCurrentTextColor();
}
@Override
public void describeTo(Description description) {
description.appendText("with text color: ");
description.appendValue(expectedId);
}
};
}
并且测试工作正常。
所以我将测试更改为使用 color_primary:
@Test
public void registerTextViewTextColor() {
onView(withId(R.id.registerTextView)).check(matches(withTextColor(R.color.color_primary)));}
但现在我得到错误:
android.support.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'with text color: <2131099686>' doesn't match the selected view.
Expected: with text color: <2131099686>
Got: "AppCompatTextView{id=2131296512, res-name=registerTextView, visibility=VISIBLE, width=180, height=53, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=true, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, layout-params=android.support.constraint.ConstraintLayout$LayoutParams@9e165b3, tag=null, root-is-layout-requested=false, has-input-connection=false, x=451.0, y=1508.0, text=Register, input-type=0, ime-target=false, has-links=false}"
如果你想从颜色资源中提取整数,你的视图匹配器应该如下所示:
public static Matcher<View> withTextColor(final int expectedId) {
return new BoundedMatcher<View, TextView>(TextView.class) {
@Override
protected boolean matchesSafely(TextView textView) {
int colorId = ContextCompat.getColor(textView.getContext(), expectedId);
return textView.getCurrentTextColor() == colorId;
}
@Override
public void describeTo(Description description) {
description.appendText("with text color: ");
description.appendValue(expectedId);
}
};
}
然后这应该会给出想要的结果:
onView(withId(R.id.registerTextView)).check(matches(withTextColor(R.color.color_primary)))
这对我来说非常有用,可用于检查文本颜色。
onView(withText("你的文本")).check(匹配(withTextColor(Color.parseColor("#282828"))));
注意#282828 是颜色代码应该是正确的。
