在我的xml中，我已经添加了以下属性。
<com.project.current.widget.AutoResizeEditText
android:id="@+id/edittext_add_text_new"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:focusableInTouchMode="true"
android:hint="@string/text_sticker_hint"
android:inputType="textNoSuggestions|textVisiblePassword|textMultiLine"
android:isScrollContainer="false"
android:padding="@dimen/dimen_margin_small"
android:textColor="@color/black"
android:textColorHint="@color/blue_popover"
android:textSize="@dimen/text_font_edit_text_default"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:background="@drawable/bg_text_sticker"
android:layout_toRightOf="@+id/resize_icon_left"
android:cursorVisible="true"
android:textCursorDrawable="@null"
android:textIsSelectable="true" />
我已将Focusable和FocusableOnTouch设置为true。我也将cursorVisible设置为true。并且为了确保光标不是白色（背景发白），我将textCursorDrawable设置为'@null'
但是光标仍然在视图中不可见。我有一个为edittext实现的touchListener（因为我还需要在父布局中移动它）。所以我把键盘设置为在ACTION_UP弹出。那时我在检查时
editTextViewNew.isCursorVisible()
它返回true。但光标实际上是不可见的。如何使其可见并且我的edittext中的文本可选？ （“粘贴”复制文本的长按选项也不起作用。）
我正在使用以下Custom AutoResizeEditText根据我的需要调整editText中的文本大小。

我发现这些详细信息已经实现here，这很容易模仿我。
答案 0 :(得分：1)
android:textIsSelectable="true"
如果您想看到光标，请将其设置为false
您不必将textCursorDrawable设置为@null，因为颜色仅取决于您选择的强调色
答案 1 :(得分：0)
请从空中删除包含setMovementMethod的行，这将显示光标以更改您可以使用textCursorDrawable的可绘制光标
