我正在构建一个应用程序，我必须在同一活动中同时使用gridview和listview，但问题是gridview项目是可点击的，但不是listview，这是我的活动xml...

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/background"
android:orientation="vertical" >

<GridView
    android:id="@+id/gridView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

    android:text="Tender" />

<Button
    android:id="@+id/button4"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/linearLayout1"
    android:layout_alignParentBottom="true"
    android:layout_marginBottom="22dp"
    android:text="Delete" />

请帮助我如何使列表视图项目和行可点击......

你试过 android:clickable="true" 吗？

喜欢：

<TableRow
android:id="@+id/tableRow1"
android:clickable="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginTop="23dp" >

首先，您只需要将 2 个 RecyclerViews 对象放入您的活动/片段布局。为了以后更好的滚动，请将主题包装在 NestedScrollView 中，如下所示：activity_main.xml

<?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"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:background="#ffffe0"
    tools:context="info.devexchanges.gridlistrecyclerview.MainActivity">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingBottom="10dp"
            android:text="@string/os"
            android:textStyle="bold" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/grid"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingBottom="10dp"
            android:paddingTop="10dp"
            android:text="@string/corporation"
            android:textStyle="bold" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/list"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </LinearLayout>
</android.support.v4.widget.NestedScrollView>

当然，您总是需要为每个 RecyclerView 项目创建布局。在此每个项目都是一个 CardView：item_list.xml

<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="8dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <ImageView
            android:id="@+id/image"
            android:layout_width="60dp"
            android:layout_height="60dp"
            android:layout_marginLeft="5dp"
            android:contentDescription="@string/app_name" />

        <TextView
            android:id="@+id/text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:layout_toRightOf="@+id/image"
            android:gravity="center" />
    </RelativeLayout>
</android.support.v7.widget.CardView>

item_grid.xml

<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"
    app:cardCornerRadius="10dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center">

        <ImageView
            android:id="@+id/image"
            android:layout_width="120dp"
            android:layout_height="120dp"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="5dp"
            android:contentDescription="@null" />

        <TextView
            android:id="@+id/text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/image"
            android:layout_marginTop="5dp"
            android:background="@color/colorPrimaryDark"
            android:gravity="center"
            android:padding="5dp"
            android:textColor="#ffffff"
            android:textStyle="bold" />
    </RelativeLayout>
</android.support.v7.widget.CardView>

现在，我们必须基于 RecyclerView.Adapter 为 2 个 RecyclerViews 创建 2 个适配器类：

ListViewAdapter.java

import android.app.Activity;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import java.util.List;

import info.devexchanges.gridlistrecyclerview.R;
import info.devexchanges.gridlistrecyclerview.RecyclerViewItem;

public class ListViewAdapter extends RecyclerView.Adapter<ListViewAdapter.ViewHolder> {
    private Activity activity;
    private List<RecyclerViewItem> items;

    public ListViewAdapter(Activity activity, List<RecyclerViewItem> items) {
        this.activity = activity;
        this.items = items;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        LayoutInflater inflater = activity.getLayoutInflater();
        View view = inflater.inflate(R.layout.item_list, parent, false);

        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder viewHolder, final int position) {
        viewHolder.imageView.setImageResource(items.get(position).getDrawableId());
        viewHolder.textView.setText(items.get(position).getName());
    }

    @Override
    public int getItemCount() {
        return items.size();
    }

    /**
     * View holder to display each RecylerView item
     */
    protected class ViewHolder extends RecyclerView.ViewHolder {
        private ImageView imageView;
        private TextView textView;

        public ViewHolder(View view) {
            super(view);
            imageView = (ImageView) view.findViewById(R.id.image);
            textView = (TextView)view.findViewById(R.id.text);
        }

    }
}

GridViewAdapter.java

import android.app.Activity;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import java.util.List;

import info.devexchanges.gridlistrecyclerview.R;
import info.devexchanges.gridlistrecyclerview.RecyclerViewItem;

public class GridViewAdapter extends RecyclerView.Adapter<GridViewAdapter.ViewHolder> {
    private List<RecyclerViewItem> items;
    private Activity activity;

    public GridViewAdapter(Activity activity, List<RecyclerViewItem> items) {
        this.activity = activity;
        this.items = items;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
        LayoutInflater inflater = activity.getLayoutInflater();
        View view = inflater.inflate(R.layout.item_grid, viewGroup, false);

        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(GridViewAdapter.ViewHolder viewHolder, int position) {
        viewHolder.imageView.setImageResource(items.get(position).getDrawableId());
        viewHolder.textView.setText(items.get(position).getName());
    }

    @Override
    public int getItemCount() {
        return items.size();
    }

    /**
     * View holder to display each RecylerView item
     */
    protected class ViewHolder extends RecyclerView.ViewHolder {
        private ImageView imageView;
        private TextView textView;

        public ViewHolder(View view) {
            super(view);
            textView = (TextView)view.findViewById(R.id.text);
            imageView = (ImageView) view.findViewById(R.id.image);
        }
    }
}

在您的活动或片段编程代码中没有特别之处，从布局文件中定位所有 xml 元素，为 RecyclerViews 创建 LayoutManager，初始化适配器并附加它们，......这是我的主要活动的完整代码：

MainActivity.java

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

import java.util.ArrayList;

import info.devexchanges.gridlistrecyclerview.adapter.GridViewAdapter;
import info.devexchanges.gridlistrecyclerview.adapter.ListViewAdapter;

public class MainActivity extends AppCompatActivity {

    private RecyclerView listView;
    private RecyclerView gridView;
    private ListViewAdapter listViewAdapter;
    private GridViewAdapter gridViewAdapter;
    private ArrayList<RecyclerViewItem> corporations;
    private ArrayList<RecyclerViewItem> operatingSystems;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView = (RecyclerView) findViewById(R.id.list);
        gridView = (RecyclerView) findViewById(R.id.grid);

        setDummyData();

        listView.setHasFixedSize(true);
        gridView.setHasFixedSize(true);

        //set layout manager and adapter for "ListView"
        LinearLayoutManager horizontalManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
        listView.setLayoutManager(horizontalManager);
        listViewAdapter = new ListViewAdapter(this, corporations);
        listView.setAdapter(listViewAdapter);

        //set layout manager and adapter for "GridView"
        GridLayoutManager layoutManager = new GridLayoutManager(this, 2);
        gridView.setLayoutManager(layoutManager);
        gridViewAdapter = new GridViewAdapter(this, operatingSystems);
        gridView.setAdapter(gridViewAdapter);
    }

    private void setDummyData() {
        corporations = new ArrayList<>();
        corporations.add(new RecyclerViewItem(R.drawable.microsoft, "Microsoft"));
        corporations.add(new RecyclerViewItem(R.drawable.apple, "Apple"));
        corporations.add(new RecyclerViewItem(R.drawable.google, "Google"));
        corporations.add(new RecyclerViewItem(R.drawable.oracle, "Oracle"));
        corporations.add(new RecyclerViewItem(R.drawable.yahoo, "Yahoo"));
        corporations.add(new RecyclerViewItem(R.drawable.mozilla, "Mozilla"));

        operatingSystems = new ArrayList<>();
        operatingSystems.add(new RecyclerViewItem(R.drawable.bbos, "BlackBerry OS"));
        operatingSystems.add(new RecyclerViewItem(R.drawable.ios, "iOS"));
        operatingSystems.add(new RecyclerViewItem(R.drawable.tizen, "Tizen"));
        operatingSystems.add(new RecyclerViewItem(R.drawable.android, "Android"));
        operatingSystems.add(new RecyclerViewItem(R.drawable.symbian, "Symbian"));
        operatingSystems.add(new RecyclerViewItem(R.drawable.firefox_os, "Firefox OS"));
        operatingSystems.add(new RecyclerViewItem(R.drawable.wp_os, "Windows Phone OS"));
    }
}

这是这个项目的POJO类：RecyclerViewItem.java

public class RecyclerViewItem {

    private int drawableId;
    private String name;

    public RecyclerViewItem(int drawableId, String name) {
        this.drawableId = drawableId;
        this.name = name;
    }

    public int getDrawableId() {
        return drawableId;
    }

    public String getName() {
        return name;
    }
}

注意：永远不要忘记将 RecyclerView 和 CardView 依赖项放入您的应用程序级 build.gradle 文件：

implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
