AndroidStudio子listview中单击和长按效果的实现

首先在listview在实施中添加数据调整

mListView.setOnItemClickListener(this); mListView.setOnItemLongClickListener(this);然后实现重写方法。

核心代码

@Override public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { //点击事件 @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(MainActivity.this, "你刚才点击的是item:" + position + "id为:" + id, Toast.LENGTH_SHORT).show(); } });

}

@Override public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) { mListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() { //长按事件 @Override public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(MainActivity.this,"你刚才按了很久item:" + position + "id为:" + id,Toast.LENGTH_SHORT).show(); return true; } }); return true; }

具体代码如下：

package com.example.dymemory1;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity implements AdapterView.OnItemClickListener, AdapterView.OnItemLongClickListener {
    private ListView mListView;
    private String[] titles = {"苹果", "蛋糕", "桌子", "猕猴桃", "毛衣"};
    private String[] prices = {"10元/kg", "100元/个", "45元/把", "10元/kg", "110元/件"};

    private int[] icons = {R.drawable.apple, R.drawable.cake, R.drawable.table, R.drawable.kiwifruit, R.drawable.wireclothes};

    protected void onCreate(Bundle saveInstanceState) {
        super.onCreate(saveInstanceState);
        setContentView(R.layout.activity_main);

        mListView = (ListView) findViewById(R.id.lv);

        MyBaseAdaPter mAdapter = new MyBaseAdaPter();

        mListView.setAdapter(mAdapter);
        mListView.setOnItemClickListener(this);
        mListView.setOnItemLongClickListener(this);
    }

    @Override
    public void onItemClick(AdapterView adapterView, View view, int i, long l) {
        mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {        //点击事件
            @Override
            public void onItemClick(AdapterView parent, View view, int position, long id) {
                Toast.makeText(MainActivity.this, "你刚才点击的是item:" + position + "id为:" + id, Toast.LENGTH_SHORT).show();
            }
        });

    }

    @Override
    public boolean onItemLongClick(AdapterView adapterView, View view, int i, long l) {
         mListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {       //长按事件
        @Override
        public boolean onItemLongClick(AdapterView parent, View view, int position, long id) {
            Toast.makeText(MainActivity.this,"你刚才按了很久item:" + position + "id为:" + id,Toast.LENGTH_SHORT).show();
            return true;
        }
    });
        return true;
    }

    class MyBaseAdaPter extends BaseAdapter {
        @Override
        public int getCount() {
            return titles.length;
        }

        @Override
        public Object getItem(int position) {
            return titles[position];
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder holder = null;
            if (convertView == null) {
                convertView = View.inflate(MainActivity.this, R.layout.list_item, null);
                holder = new ViewHolder();
                holder.title = (TextView) convertView.findViewById(R.id.title);
                holder.price = (TextView) convertView.findViewById(R.id.price);
                holder.iv = (ImageView) convertView.findViewById(R.id.iv);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }
            holder.title.setText(titles[position]);
            holder.price.setText(prices[position]);
            holder.iv.setBackgroundResource(icons[position]);
            return convertView;
        }
    }

    static class ViewHolder {
        TextView title;
        TextView price;
        ImageView iv;
    }
}
     /*mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {        //点击事件
        @Override
        public void onItemClick(AdapterView parent, View view, int position, long id) {
            Toast.makeText(MainActivity.this,"单击索引:" + position + "id为:" + id,Toast.LENGTH_SHORT).show();
        }
    });
*/
            /* mListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {       //长按事件
        @Override
        public boolean onItemLongClick(AdapterView parent, View view, int position, long id) {
            Toast.makeText(MainActivity.this,"单击索引:" + position + "id为:" + id,Toast.LENGTH_SHORT).show();
            return true;
        }
    });*/

这是MainActivity.java文件，activity_main.xml和item_xml文件未复制！

最后，看看效果图
