在操作栏进度 [英] ProgressBar under Action Bar

问题描述

问摘要：我怎样才能让一个进度集成在动作条，像Chrome应用？

Question Summary: How can I make a ProgressBar integrated inside the ActionBar, like on the Chrome App?

详细信息：看看这张截图来自Chrome浏览器：

Details: Look at this screenshot from Chrome:

我想创建一个操作栏，就像这样。刚下操作栏，有一个进度条，根据页面加载罢了。我已经看到了这个例子从许多应用程序，像Feedly，但我一直没能创造我自己的实现。我试图使用Android的自己的API来创建它：

I want to create an Action Bar just like this. Just under the Action Bar, there's a ProgressBar that fills according to page load. I've seen this example from many apps, like Feedly, but I haven't been able to create my own implementation. I tried using Android's own APIs to create it:

@Override
protected void onCreate(Bundle savedInstanceState) {
    //Request Permission to display the Progress Bar...
    this.requestWindowFeature(Window.FEATURE_PROGRESS);
            this.setWindowContentView(R.layout.activity_main)
    super.onCreate(savedInstanceState);

    this.setProgressBarIndeterminate(true);
}

但是，这code只能导致进度条显示的在的操作栏，如下所示：

But this code only causes the ProgressBar to show over the Action Bar, like so:

所以，我怎么能下的操作栏我的进度条出现，就像在Chrome应用程序？

So, how can I make my ProgressBar appear under the Action Bar, like on the Chrome App?

推荐答案

这是目前可以使用的 SwipeRefreshLayout 。

你可以用你的滚动视图使用 SwipeRefreshLayout ，然后你只需要听的 onRefresh 的事件：

You can wrap your scrollable view with a SwipeRefreshLayout and then you just need to listen to onRefresh events:

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

    swipeLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_container);
    swipeLayout.setOnRefreshListener(this);
    swipeLayout.setColorScheme(android.R.color.holo_blue_bright, 
            android.R.color.holo_green_light, 
            android.R.color.holo_orange_light, 
            android.R.color.holo_red_light);
}


@Override public void onRefresh() {
    new Handler().postDelayed(new Runnable() {
        @Override public void run() {
            swipeLayout.setRefreshing(false);
        }
    }, 5000);
}
