                Matcher<T> matcher)

A replacement for MatcherAssert.assertThat that renders View objects nicely.

Parameters
`message`	`String`: the message to display.
`actual`	`T`: the actual value.
`matcher`	`Matcher`: a matcher that accepts or rejects actual.

Returns
`Matcher<View>`

hasErrorText

Matcher<View> hasErrorText (String expectedError)

Returns a matcher that matches EditText based on edit text error string value.

Note: Sugar for hasErrorText(is("string")).

Parameters

Returns a matcher that matches Views currently have focus.

Returns
`Matcher<View>`

hasImeAction

Matcher<View> hasImeAction (int imeAction)

Returns a matcher that matches views that support input methods (e.g. EditText) and have the specified IME action set in its EditorInfo.

Parameters
`imeAction`	`int`: the IME action to match

Returns
`Matcher<View>`

hasImeAction

Matcher<View> hasImeAction (Matcher<Integer> imeActionMatcher)

Returns a matcher that matches views that support input methods (e.g. EditText) and have the specified IME action set in its EditorInfo.

Returns a matcher that matches TextViews that have links.

Returns
`Matcher<View>`

hasSibling

Matcher<View> hasSibling (Matcher<View> siblingMatcher)

Returns an Matcher that matches Views based on their siblings.

This may be particularly useful when a view cannot be uniquely selected on properties such as text or R.id. For example: a call button is repeated several times in a contacts layout and the only way to differentiate the call button view is by what appears next to it (e.g. the unique name of the contact).

Parameters

Returns
`Matcher<View>`

isAssignableFrom

Matcher<View> isAssignableFrom (Class<? extends View> clazz)

Returns a matcher that matches Views which are an instance of or subclass of the provided class. Some versions of Hamcrest make the generic typing of this a nightmare, so we have a special case for our users.

Parameters
`clazz`	`Class`

Returns
`Matcher<View>`

isChecked

Matcher<View> isChecked ()

Returns a matcher that accepts if and only if the view is a CompoundButton (or subtype of) and is in checked state.

Returns a matcher that matches Views that are clickable.

Returns
`Matcher<View>`

isCompletelyDisplayed

Matcher<View> isCompletelyDisplayed ()

Returns a matcher which only accepts a view whose height and width fit perfectly within the currently displayed region of this view. There exist views (such as ScrollViews) whose height and width are larger then the physical device screen by design. Such views will _never_ be completely displayed.

Returns
`Matcher<View>`

isDescendantOfA

Matcher<View> isDescendantOfA (Matcher<View> ancestorMatcher)

Returns a matcher that matches Views based on the given ancestor type.

Parameters
`ancestorMatcher`	`Matcher`: the type of the ancestor to match on

Returns
`Matcher<View>`

isDisplayed

Matcher<View> isDisplayed ()

Returns a matcher that matches Views that are currently displayed on the screen to the user. Note: isDisplayed will select views that are partially displayed (eg: the full height/width of the view is greater then the height/width of the visible rectangle). If you wish to ensure the entire rectangle this view draws is displayed to the user use isCompletelyDisplayed.

Returns
`Matcher<View>`

isDisplayingAtLeast

Matcher<View> isDisplayingAtLeast (int areaPercentage)

Returns a matcher which accepts a view so long as a given percentage of that view's area is not obscured by any other view and is thus visible to the user.

Returns
`Matcher<View>`

isEnabled

Returns a matcher that matches Views that are enabled.

Returns
`Matcher<View>`

Matcher<View> supportsInputMethods ()

Returns a matcher that matches views that support input methods.

Returns
`Matcher<View>`

withChild

Matcher<View> withChild (Matcher<View> childMatcher)

A matcher that returns true if and only if the view's child is accepted by the provided matcher.

Parameters
`childMatcher`	`Matcher`: the matcher to apply on the child views.

Returns
`Matcher<View>`

withClassName

Matcher<View> withClassName (Matcher<String> classNameMatcher)

Returns a matcher that matches Views with class name matching the given matcher.

Parameters
`classNameMatcher`	`Matcher`

Returns
`Matcher<View>`

withContentDescription

Matcher<View> withContentDescription (int resourceId)

Returns a Matcher that matches Views based on content description property value.

Parameters
`resourceId`	`int`: the resource id of the content description to match on.

Returns
`Matcher<View>`

withContentDescription

Matcher<View> withContentDescription (String text)

Returns an Matcher that matches Views based on content description property value. Sugar for withContentDescription(is("string")).

Parameters
`text`	`String`: the text to match on.

Returns
`Matcher<View>`

withContentDescription

Matcher<View> withContentDescription (Matcher<? extends CharSequence> charSequenceMatcher)

Returns an Matcher that matches Views based on content description property value.

Parameters
`charSequenceMatcher`	`Matcher`: a `CharSequence` `Matcher` for the content description

Returns
`Matcher<View>`

withEffectiveVisibility

Matcher<View> withEffectiveVisibility (ViewMatchers.Visibility visibility)

Returns a matcher that matches Views that have "effective" visibility set to the given value. Effective visibility takes into account not only the view's visibility value, but also that of its ancestors. In case of View.VISIBLE, this means that the view and all of its ancestors have visibility=VISIBLE. In case of GONE and INVISIBLE, it's the opposite - any GONE or INVISIBLE parent will make all of its children have their effective visibility.

Note: Contrary to what the name may imply, view visibility does not directly translate into whether the view is displayed on screen (use isDisplayed() for that). For example, the view and all of its ancestors can have visibility=VISIBLE, but the view may need to be scrolled to in order to be actually visible to the user. Unless you're specifically targeting the visibility value with your test, use isDisplayed.

Parameters
`visibility`	`ViewMatchers.Visibility`

Returns
`Matcher<View>`

withHint

Matcher<View> withHint (Matcher<String> stringMatcher)

Returns a matcher that matches TextViews based on hint property value. Note: View's hint property can be null.
