[英]How to put TextView below RecyclerView in NestedScrollView in android
[英]Textview doesnot shows up above RecyclerView in nestedscrollview android
<?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:keepScreenOn="true"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.tech.world.MainActivity"
tools:showIn="@layout/app_bar_main_activity"
android:fillViewport="true" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin" >
<TextView
android:id="@+id/textView"
android:textColor="#43a047"
android:typeface="serif"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="@string/app"
android:gravity="center"
android:textStyle="bold"
android:textSize="15sp" />
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/recyclerview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/textView"
android:layout_marginTop="10dp"
android:divider="@color/colorAccent"
android:dividerHeight="1dp" />
</RelativeLayout> </android.support.v4.widget.NestedScrollView>
現在上面的textview沒有顯示,我必須向下滾動以查看textview,我也使用工具欄,由於這個應用程序擴展和聯系協調器布局:layout_behavior =“@ string / appbar_scrolling_view_behavior”
我想確保textview在啟動時可見,而不需要滾動一下就可以看到它
將android:focusableInTouchMode="true"
為您的回收站視圖的父布局,即您的相對布局。

切換到ConstraintLayout是我的解決方案
我的工作代碼使用CoordinatorLayout
