Android ListView左滑刪除、左滑自定義功能

最近項目需要ListView左滑刪除功能，搜集了很多資料發現了一個某一前輩寫的庫能很簡單的實現這個功能，而且有源碼，直接拿來使用了。

庫名字叫做SwipeMenuListView，下面給大家演示一下使用方法，不用謝。

首先在項目中加入庫，這個不再介紹了。

布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    android:background="#E3E6ED">

    <com.baoyz.swipemenulistview.SwipeMenuListView
        android:id="@+id/collector_listview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" 
        android:divider="#00000000"
         android:dividerHeight="1dp"
         android:fadingEdge="none"
         android:fastScrollEnabled="false"
         android:smoothScrollbar="true">
    </com.baoyz.swipemenulistview.SwipeMenuListView>
    
    <TextView 
        android:id="@+id/collector_listview_empty"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:text="@string/listisempty"
        android:textColor="@color/black"
        android:textAppearance="?android:attr/textAppearanceLarge">
    </TextView>

</LinearLayout>

 

數據適配器：

public class CollectorListAdapter extends BaseAdapter   {

    private List<SystemDevice> listItems;//數據集合
    private LayoutInflater layoutinflater;//視圖容器，用來導入布局
    
    static class ViewHolder
    {
        private TextView serialNumber;
        private TextView articleNumber;
        private ImageView image;
    }
    
    /*
     * 實例化Adapter
     */
    public CollectorListAdapter(Context context, List<SystemDevice> dataSet)
    {
        this.listItems = dataSet;
        this.layoutinflater = LayoutInflater.from(context);
    }
    
    @Override
    public int getCount() {
        return listItems.size();
    }

    @Override
    public Object getItem(int position) {
        return listItems.get(position);
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        SystemDevice device = listItems.get(position);
        ViewHolder holder;
        View view;
        if(convertView == null)
        {
            holder= new ViewHolder();
            //獲取listitem布局文件
            view = layoutinflater.inflate(R.layout.collectorlist_listitem, null);
            
            //獲取控件對象
            holder.serialNumber = (TextView) view.findViewById(R.id.collectorlist_serialnumber);
            holder.articleNumber = (TextView) view.findViewById(R.id.collectorlist_articlelnumber);
            holder.image = (ImageView) view.findViewById(R.id.collectorlist_image);
            
            view.setTag(holder);
        }
        else
        {
            view = convertView;
            holder = (ViewHolder) view.getTag();
        }
        
        //設置圖片和文字
        holder.serialNumber.setText(String.valueOf(device.getSerialNumber()));
        holder.articleNumber.setText(String.valueOf(device.getArticleNumber()));
        
        return view;
    }

}

實現代碼：

    private SwipeMenuListView listView;

    //初始化ListView數據，在OnCreate方法中調用
    private void initData()
    {
        final List<SystemDevice> data = new SystemDeviceDao(context).queryAllSystemDevice();
        final CollectorListAdapter adapter = new CollectorListAdapter(context, data);
        
        listView.setAdapter(adapter);
        listView.setEmptyView(activity.findViewById(R.id.collector_listview_empty));
        
        
        // step 1. create a MenuCreator
        SwipeMenuCreator creator = new SwipeMenuCreator() 
        {
            @Override
            public void create(SwipeMenu menu) 
            {
                // create "open" item
                SwipeMenuItem openItem = new SwipeMenuItem(activity.getApplicationContext());
                // set item background
                openItem.setBackground(new ColorDrawable(Color.rgb(0xC9, 0xC9, 0xCE)));
                // set item width
                openItem.setWidth(dp2px(90));
                // set item title
                openItem.setTitle("打開");
                // set item title fontsize
                openItem.setTitleSize(18);
                // set item title font color
                openItem.setTitleColor(Color.WHITE);
                // add to menu
                menu.addMenuItem(openItem);

                // create "delete" item
                SwipeMenuItem deleteItem = new SwipeMenuItem(activity.getApplicationContext());
                // set item background
                deleteItem.setBackground(new ColorDrawable(Color.rgb(0xF9, 0x3F, 0x25)));
                // set item width
                deleteItem.setWidth(dp2px(90));
                // set a icon
                deleteItem.setIcon(R.drawable.ic_delete);
                // add to menu
                menu.addMenuItem(deleteItem);
            }
        };
        
        // set creator
        listView.setMenuCreator(creator);

        // step 2. listener item click event
        listView.setOnMenuItemClickListener(new OnMenuItemClickListener() 
        {
            @Override
            public void onMenuItemClick(int position, SwipeMenu menu, int index) 
            {
                SystemDevice device = data.get(position);
                
                switch (index) 
                {
                case 0:
                    // open
                    open(device);
                    break;
                case 1:
                    // delete
                    delete(device);
                    data.remove(position);
                    adapter.notifyDataSetChanged();
                    break;
                }
            }
        });
                
        // set SwipeListener
        listView.setOnSwipeListener(new OnSwipeListener() 
        {
            @Override
            public void onSwipeStart(int position) 
            {
                // swipe start
            }
                    
            @Override
            public void onSwipeEnd(int position) 
            {
                // swipe end
            }
        });
        
        listView.setOnItemClickListener(new OnItemClickListener() 
        {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                
                SystemDevice device = data.get(position);
                open(device);
            }
        });
    }

    private int dp2px(int dp) {
        return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp,
                getResources().getDisplayMetrics());
    }
    
    /**
     * 打開
     * @param item
     */
    private void open(SystemDevice item)
    {
        
    }
    
    /**
     * 刪除
     * @param item
     */
    private void delete(SystemDevice item)
    {
        
    }
    

效果：

 

 

 

可以自定義左滑功能，大家自己開發。
