Question

我有一个ConstraintLayout以及一个RecyclerView和SearchView。问题是，当我单击SearchButton进行写操作时，RecycleView重叠在上面。

我将它们之间的点连接起来，并尝试了不同的方法，但结果始终相同。如何防止重叠？

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">


    <SearchView
        android:background="@color/colorGray"
        android:id="@+id/mySearchView"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.0"
        app:layout_constraintStart_toStartOf="@+id/myRecycleView"
        app:layout_constraintTop_toTopOf="parent" />

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/myRecycleView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.0"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/mySearchView"
        app:layout_constraintVertical_bias="0.466" />

</androidx.constraintlayout.widget.ConstraintLayout>

Answer 1

尝试这些简单的约束条件

    <?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <SearchView
        android:id="@+id/mySearchView"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:background="@color/dark_gray"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/myRecycleView"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginBottom="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/mySearchView" />

</androidx.constraintlayout.widget.ConstraintLayout>

Answer 2

从您的app:layout_constraintStart_toStartOf="@+id/myRecycleView"中删除SearchView

并在您的app:layout_constraintTop_toTopOf="parent"中添加SearchView

尝试一下

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">


    <SearchView
        android:id="@+id/mySearchView"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:background="@color/colorAccent"
        app:layout_constraintBottom_toTopOf="@+id/myRecycleView"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/myRecycleView"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:background="@color/colorPrimary"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/mySearchView" />

</androidx.constraintlayout.widget.ConstraintLayout>

Answer 3

在约束布局中尝试一下。

 <SearchView
    android:id="@+id/mySearchView"
    android:layout_width="0dp"
    android:layout_height="48dp"
    android:background="@color/colorPrimary"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/myRecycleView"
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:layout_constraintTop_toBottomOf="@+id/mySearchView"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintBottom_toBottomOf="parent"/>

Answer 4

将高程添加到搜索视图。

android:elevation="10dp"

或者您可以使用

app:layout_constraintTop_toBottomOf="@+id/mySearchView"

注意：将高度更改为0dp

Answer 5

使用Reletive Layout并在recyclerview之后粘贴search-view xml代码。它将解决您的问题，因为在reletivelayout布局中，最后的项目始终位于另一个项目之上
