从列表视图中删除项从左到右滑动

Question

我想弄清楚从左到右滑动时如何从列表视图中删除项目。我将在下面附上我的代码。截至目前，我正在使用SQLite数据库并创建了我自己的自定义列表视图适配器。我正在创建一个简单的列表来删除并添加项目。我有添加项目工作，现在我只需要弄清楚如何从左到右删除列表视图中的项目。我的想法是当你从左向右滑动时，出现一个表示删除的按钮。用户可以点击它从列表中删除项目。

main_menu_activity.java

public class main_menu_activity extends Activity 
{ 
    DatabaseHandler db; 
    ArrayList<Account> account_details; 
    ListView accountList; 

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

     accountList = (ListView)findViewById(R.id.accountListView); 

     // Initiates SQLite Database 
     db = new DatabaseHandler(getApplicationContext()); 
     // Displays ListView 
     displayListView(); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) 
    { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.main_menu_activity, menu); 

     return super.onCreateOptionsMenu(menu); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) 
    { 
     // take appropriate action for each action item clicked 
     switch(item.getItemId()) 
     { 
      case R.id.action_add_new: 
      { 
       // perform add new item action

       input.setHint("Account Name"); 
       layout.addView(input); 

       final EditText input2 = new EditText(this); 
       input2.setHint("Account Balance"); 
       layout.addView(input2); 

       alert.setView(layout); 

       alert.setPositiveButton("Save", new DialogInterface.OnClickListener() {

          db.addAccount(temp_account); 
          displayListView();

    }
