问题说明
是否可以使用浓缩咖啡检查背景颜色是否与给定颜色匹配?
Is it possible to check if the background color matches a given color with espresso?
更新:
我做了一个自定义匹配器，类似于@Irfan 建议的，谢谢！
I made a custom matcher, similar to what @Irfan suggested, thanks!
public static Matcher<Object> backgroundShouldHaveColor(int expectedColor) {
return buttondShouldHaveBackgroundColor(equalTo(expectedColor));
}
private static Matcher<Object> buttonShouldHaveBackgroundColor(final Matcher<Integer> expectedObject) {
final int[] color = new int[1];
return new BoundedMatcher<Object, Button>( Button.class) {
@Override
public boolean matchesSafely(final Button actualObject) {
color[0] =((ColorDrawable) actualObject.getBackground()).getColor();
if( expectedObject.matches(color[0])) {
return true;
} else {
return false;
}
}
@Override
public void describeTo(final Description description) {
// Should be improved!
description.appendText("Color did not match " color[0]);
}
};
}

我不确定，但我们可以检索一些元素的颜色，如按钮和文本视图 `
I am not sure about that but we can retrieve the color of some of elements like button and text views `
Button button = (Button) findViewById(R.id.my_button);
Drawable buttonBackground = button.getBackground();
你可以试试这个
ColorDrawable b_color = (ColorDrawable) button.getBackground();
然后
int color = b_color.getColor();
if (color == R.color.green) {
log("color is green");
}
希望这能帮助您入门.
