Android中解决ListView和SwipeRefreshLayout的滑动冲突

贴上代码

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".ListActivity">

    <android.support.v4.widget.SwipeRefreshLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/swipe_layout">

        <ListView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/list_view">
        </ListView>

    </android.support.v4.widget.SwipeRefreshLayout>

</LinearLayout>

MainActivity.java:

package cn.edu.sdnu.i.smartcommunity;

import android.os.Handler;
import android.support.v4.widget.SwipeRefreshLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.AbsListView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

    private String str = "测试数据";
    private List<String> list = new ArrayList<>();

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

        for(int i=0;i<60;i++){
            list.add(str);
        }
        Log.e("size:", String.valueOf(list.size()));

        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,list);
        ListView listView = findViewById(R.id.list_view);
        listView.setAdapter(arrayAdapter);

        final SwipeRefreshLayout swipeRefreshLayout = findViewById(R.id.swipe_layout);
        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        //获取后台数据，并更新list
                        Toast.makeText(ListActivity.this, "获取后台数据，并更新list", Toast.LENGTH_SHORT).show();
                        swipeRefreshLayout.setRefreshing(false);
                    }
                },2000);
            }
        });
        //实现滑倒顶端才能下拉刷新（即解决滑动冲突）
        listView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView absListView, int i) {

            }

            @Override
            public void onScroll(AbsListView absListView, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                if(firstVisibleItem == 0){
                    swipeRefreshLayout.setEnabled(true);
                }else {
                    swipeRefreshLayout.setEnabled(false);
                }
            }
        });
    }
}

以上是通过一个简单的布局和简单的ListView进行演示，关键起作用的代码段是：

 //实现滑倒顶端才能下拉刷新（即解决滑动冲突）
        listView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView absListView, int i) {

            }

            @Override
            public void onScroll(AbsListView absListView, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                if(firstVisibleItem == 0){
                    swipeRefreshLayout.setEnabled(true);
                }else {
                    swipeRefreshLayout.setEnabled(false);
                }
            }
        });
