安卓：为响应的用户界面的最佳实践 [英] Android: Best practice for responsive user interfaces

问题描述

我很新到Android和Java。我正在用C ++哪里哪里与信息调度的事件之前。现在，我想创造Android平台相同的用户体验，我想AP preciate任何您对什么是将事件绑定到用户控件的最佳方法的建议和意见。

I am quite new to Android and Java. Before I was working with C++ where the events where dispatched with messages. Now I would like to create the same user experience for Android platform and I would appreciate any of your suggestions or comments on what is the best way to bind events to user controls.

下面是C ++的一个例子：

Here is an example from C++:

ON_MESSAGE(WM_RECORD_START, &CMainFrame::OnRecordStart)//Method OnRecordStarts() executes on WM_RECORD_START_MESSAGE

...

LRESULT CMainFrame::OnRecordStart(WPARAM wParam, LPARAM lParam)
{

        m_pNetworkCtrl->SetGeoLocationInfo();
        ...
}

...

void CMainFrame::RecordStart()
{
    PostMessage(WM_RECORD_START);
}

在上面的方法的情况下 RecordStart（）绑定到按钮（被执行时按钮是pressed）和职位的消息 WM_RECORD_START 。当消息 WM_RECORD_START 收到，该方法 OnRecordStart（）被执行。

In the case above the method RecordStart() is bound to a Button (it is executed when a Button is pressed) and posts the message WM_RECORD_START. When the message WM_RECORD_START is received, the method OnRecordStart() is executed.

如前所述，我想创建一个响应的用户界面，我不知道这是否会不够好，如果该方法 OnRecordStart（）是直接从<$称为C $ C> RecordStart（）：

As mentioned before I would like to create a responsive user interface and am not sure if it would be good enough if the method OnRecordStart() is called directly from RecordStart():

void RecordStart()
{
    OnRecordStart();
}

我真的AP preciate你的任何建议。

I would really appreciate any of your suggestions.

推荐答案

您可以通过使用的处理器张贴可运行到消息队列。

You can emulator the MFC style behavior in Android by using a Handler to post a Runnable into the message queue.

下面是一个简单的例子

class MyClass
{
    Handler m_myHandler;
    Runnable m_myRunnable;

    MyClass()
    {
        m_myHandler = new Handler();
        m_myRunnable = new RUnnable()
        {
            public void run()
            {
                // do your stuff here
            }
        };
    }

    public void onclickListener(...)
    {
        // push the runnable into the message queue
        m_myHandler.post(m_myRUnnable);
    }
}
