如果是双击,1秒内连续点击判断为双击，需要判断时间和两次双击的ID是否相同。

// 双击事件记录最近一次点击的ID
private static Long LastClickId;
//双击事件记录最近一次点击的时间
private static long LastClickTime = 0;

protected void onListItemClick(ListView l, View v, int position, long id){super.onListItemClick(l,v,position,id); // 如果是双击,1秒内连续点击判断为双击if((LastClickId != null)&&(Math.abs(LastClickTime-System.currentTimeMillis()) < 1000)){LastClickId = null;LastClickTime = 0;Cursor c = m_DiaryCursor;c.moveToPosition(position);System.out.println("选中"+position);Intent i = new Intent(this, DiaryEditActivity.class);System.out.println("数据库ID"+id);i.putExtra(DiaryDbAdapter.KEY_ROWID, id);i.putExtra(DiaryDbAdapter.KEY_TITLE, c.getString(c.getColumnIndexOrThrow(DiaryDbAdapter.KEY_TITLE)));i.putExtra(DiaryDbAdapter.KEY_BODY, c.getString(c.getColumnIndexOrThrow(DiaryDbAdapter.KEY_BODY)));startActivityIfNeeded(i, ACTIVITY_EDIT);}else{LastClickId = id;LastClickTime = System.currentTimeMillis();}}
