在 textView 中使用 textIsSelectable

Question

我android:textIsSelectable="true"用于TextView。

启用复制/选择/粘贴就TextView可以了

问题

当我打开这个活动时，它会自动滚动到中间，就像这个链接

为什么会出现这个问题？

这是我的布局代码。

<?xml version="1.0" encoding="utf-8"?>

<layout xmlns:android="http://schemas.android.com/apk/res/android"

        xmlns:app="http://schemas.android.com/apk/res-auto"

        xmlns:bind="http://schemas.android.com/apk/res/android" >

    <data>

            <variable

                name="aboutMbti"

                type="mbtitest.kiars.me.mbti.model.AboutMbti"/>

Answer 1

解决方案您可以添加android:focusableInTouchMode="true"或添加android:descendantFocusability="blocksDescendants"到子布局中NestedScrollView在您的布局中尝试以下代码：<android.support.v4.widget.NestedScrollView&nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; ...... >&nbsp; &nbsp; <RelativeLayout&nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; android:focusableInTouchMode="true" >&nbsp; &nbsp; ...........

最后，根据https://stackoverflow.com/users/6891563/khemraj的评论，我发现我的解决方案...只需像这样添加android:focusableInTouchMode="true"到 ImageView ：<?xml version="1.0" encoding="utf-8"?><layout xmlns:android="http://schemas.android.com/apk/res/android"&nbsp; &nbsp; &nbsp; &nbsp; xmlns:app="http://schemas.android.com/apk/res-auto"&nbsp; &nbsp; &nbsp; &nbsp; xmlns:bind="http://schemas.android.com/apk/res/android" >&nbsp; &nbsp; <data>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <variable&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; name="aboutMbti"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; type="mbtitest.kiars.me.mbti.model.AboutMbti"/>&nbsp;&nbsp;&nbsp; &nbsp; </data>&nbsp; &nbsp; <RelativeLayout&nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; app:layout_behavior="@string/appbar_scrolling_view_behavior">&nbsp; &nbsp; &nbsp; &nbsp; <androidx.cardview.widget.CardView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; app:cardBackgroundColor="@android:color/white"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; app:cardCornerRadius="2dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; app:cardElevation="5dp" >&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <androidx.core.widget.NestedScrollView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:fillViewport="true"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:fitsSystemWindows="true"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:scrollbarSize="1dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:scrollbarThumbVertical="@android:color/white">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <RelativeLayout&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="match_parent">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <ImageView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/img_splash_mtbi"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="200dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_margin="3dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:adjustViewBounds="true"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:padding="5dp"android:focusableInTouchMode="true"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:scaleType="centerCrop"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; bind:imageUrl="@{aboutMbti.imageUrl}"/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <TextView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/txt_content_about_mtbi"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_below="@+id/img_splash_mtbi"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_margin="5dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textIsSelectable="true"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:padding="@dimen/title_padding"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:text="@{aboutMbti.textContent}"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textColor="@color/ques_title"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textSize="15sp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:textStyle="bold"/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </RelativeLayout>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </androidx.core.widget.NestedScrollView>&nbsp; &nbsp; &nbsp; &nbsp; </androidx.cardview.widget.CardView>&nbsp; &nbsp; </RelativeLayout></layout>Tnx 伙计们
