例如
<androidx.constraintlayout.widget.ConstraintLayout android:id="@+id/content_one" android:layout_width="match_parent" android:layout_height="@dimen/normal_100dp" android:paddingTop="@dimen/normal_0dp" android:paddingRight="@dimen/normal_24dp" >
<TextView android:id="@+id/tv_location" android:layout_width="@dimen/normal_480sp" android:layout_height="wrap_content" android:layout_marginLeft="@dimen/normal_16dp" android:maxLines="2" android:inputType="text" android:textColor="@color/color_222222" android:textSize="@dimen/normal_24sp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toRightOf="@+id/view_01" app:layout_constraintTop_toTopOf="parent" tools:text="广东省深圳市宝安区留仙二路庭威工业园二栋三楼" /> </androidx.constraintlayout.widget.ConstraintLayout> item布局如下,当点击后无反应。需要把android:inputType=“text”去掉,就可以点击了!
原因:
官方是这样说明的:
Attribute android:inputType should not be used with <TextView>: Change element type to <EditText> ? less... (Ctrl+F1)
Using a <TextView> to input text is generally an error, you should be using <EditText> instead. EditText is a subclass of TextView, and some of the editing support is provided by TextView, so it's possible to set some input-related properties on a TextView. However, using a TextView along with input attributes is usually a cut & paste error. To input text you should be using <EditText>.
This check also checks subclasses of TextView, such as Button and CheckBox, since these have the same issue: they should not be used with editable attributes.
Issue id: TextViewEdits
结合以上说明,android:inputType的属性只对EditText有效,我认为EditText本身有抢夺焦点的作用,给TextView设置android:inputType的属性后可能也会导致焦点抢夺,导致点击“Text”文本并不会触发条目点击事件,而是被自身消耗掉了。也可以理解为点击事件被屏蔽掉了。
这里,要感谢下我的朋友margintop,他后来发现:如果已经设置了android:inputType的属性,再设置两个属性android:clickable和android:longClickable,这两个属性都设置成false,也可以达到预期的效果。也就是说android:inputType改变了那两个属性的默认值,把false改成了true。
