操作栏中的菜单项无效

Question

您好我添加了菜单文件，有3个菜单项：

1）菜单图钉，

2）发送回复和

3）添加笔记。

发送回复，添加备注工作正常但是，当删除针脚的注释时，它无法正常工作。我附上了以下代码。

请建议我任何解决方案。当我将发送回复的代码粘贴到pin_menu案例以进行测试时，它无效。

Log cat没有显示任何内容。我在点击pin_menu时添加了吐司，它没有显示。请建议我解决。

我还尝试在XML文件中添加一个额外的菜单，并添加了与pin_menu相同但不起作用的代码。没有显示log cat，toast。所以很难调试。发送回复和添加注释，但两者都工作正常。

代码如下：

 <item android:id="@+id/menu_pin"
      android:icon="@drawable/pin"
      android:title="@string/pin"
      android:showAsAction="never" 
      />

<item android:id="@+id/menu_send_reply"
      android:icon="@drawable/send"
      android:title="@string/send_reply"
      android:showAsAction="never" 
      />

<item android:id="@+id/menu_add_note"
      android:icon="@drawable/add_note"
      android:title="@string/add_note"
      android:showAsAction="never" 
       />

                            @Override
                public boolean onCreateOptionsMenu(Menu menu) {
                    // TODO Auto-generated method stub
                    MenuInflater menuInflater = getMenuInflater();
                    menuInflater.inflate(R.menu.ticket_properties_menu, menu);
                    return true;
                }

                @Override
                public boolean onOptionsItemSelected(MenuItem item) {

                    Log.d("DATA ","Item ID "+item.getItemId());
                    // TODO Auto-generated method stub
                    switch (item.getItemId())
                    {
                    case R.id.menu_add_note:

                        Intent i3 = new Intent(Ticket_properties.this,Add_note.class);
                        i3.putExtra("ID", Ticket_id);
                        i3.putExtra("client_id", client_id);
                        startActivity(i3);
                        return true;

                    case R.id.menu_send_reply:

                        Intent reply= new Intent(Ticket_properties.this,Send_reply.class);
                        reply.putExtra("ticket_id", Ticket_id);
                        reply.putExtra("title", Ticket_title);
                        reply.putExtra("dept_id", tv_dept_id.getText());
                        reply.putExtra("Ticket_hash", Ticket_hash);
                        reply.putExtra("filter_id",filter_id);
                        startActivity(reply);
                        return true;

                    case R.id.menu_pin:

                        Intent reply1= new Intent(Ticket_properties.this,Send_reply.class);
                        reply1.putExtra("ticket_id", Ticket_id);
                        reply1.putExtra("title", Ticket_title);
                        reply1.putExtra("dept_id", tv_dept_id.getText());
                        reply1.putExtra("Ticket_hash", Ticket_hash);
                        reply1.putExtra("filter_id",filter_id);
                        startActivity(reply1);
                        return true;

                        /*
                      String PIN_URL=op.getUrl(Ticket_properties.this,"ticket", "add_pinup","&vis_ticket_id=124");
                      JSONArray pin_result = JSONfunctions.getJSONfromURL(PIN_URL+"&vis_encode=json",Ticket_properties.this);
                      String result =pin_result.toString();
                      if(result.equals("[\"success\"]"))
                      {             
                            Operation.showToast(getApplicationContext(),R.string.pinned);           
                      }
                      */

                  default:
                        return super.onOptionsItemSelected(item);
                    }


                }

我认为您在错误的地方使用此注释代码。您应该在返回之前使用它，在开关盒结构中。如果你想点击引脚触发它。这是更新的代码;

@Override
            public boolean onCreateOptionsMenu(Menu menu) {
                // TODO Auto-generated method stub
                MenuInflater menuInflater = getMenuInflater();
                menuInflater.inflate(R.menu.ticket_properties_menu, menu);
                return true;
            }

            @Override
            public boolean onOptionsItemSelected(MenuItem item) {

                Log.d("DATA ","Item ID "+item.getItemId());
                // TODO Auto-generated method stub
                switch (item.getItemId())
                {
                case R.id.menu_add_note:

                    Intent i3 = new Intent(Ticket_properties.this,Add_note.class);
                    i3.putExtra("ID", Ticket_id);
                    i3.putExtra("client_id", client_id);
                    startActivity(i3);
                    return true;

                case R.id.menu_send_reply:

                    Intent reply= new Intent(Ticket_properties.this,Send_reply.class);
                    reply.putExtra("ticket_id", Ticket_id);
                    reply.putExtra("title", Ticket_title);
                    reply.putExtra("dept_id", tv_dept_id.getText());
                    reply.putExtra("Ticket_hash", Ticket_hash);
                    reply.putExtra("filter_id",filter_id);
                    startActivity(reply);
                    return true;

                case R.id.menu_pin:

                                          String PIN_URL=op.getUrl(Ticket_properties.this,"ticket", "add_pinup","&vis_ticket_id=124");
                  JSONArray pin_result = JSONfunctions.getJSONfromURL(PIN_URL+"&vis_encode=json",Ticket_properties.this);
                  String result =pin_result.toString();
                  if(result.equals("[\"success\"]"))
                  {             
                        Operation.showToast(getApplicationContext(),R.string.pinned);           
                  }
                    Intent reply1= new Intent(Ticket_properties.this,Send_reply.class);
                    reply1.putExtra("ticket_id", Ticket_id);
                    reply1.putExtra("title", Ticket_title);
                    reply1.putExtra("dept_id", tv_dept_id.getText());
                    reply1.putExtra("Ticket_hash", Ticket_hash);
                    reply1.putExtra("filter_id",filter_id);
                    startActivity(reply1);
                    return true;

              default:
                    return super.onOptionsItemSelected(item);
                }


            }
