检查Android设备具有搜索硬件按钮 [英] Check if Android device has search hardware button

问题描述

我需要帮助搞清楚如何检查设备是否配备有搜索硬件按钮与否。这可能吗？

I need help figuring out how to check if a device is equipped with the search hardware button or not. Is this possible?

编辑：我说的是找出如果设备有搜索硬件按钮与否。简单的问题。每一个Android设备有一组硬件按钮;菜单，主页键，返回键以及搜索键。但有些设备仅配备了其中的一部分，不是全部。

I'm talking about finding out if the device has the search hardware button or not. Simple question. Each android device has a set of hardware buttons; menu, home button, back button, and search button. But some devices is only equipped with some of them, not all.

编辑2：为什么我问的是，因为我想有一个软件按钮会显示在用户界面，如果该设备的不是的配备了一个硬件按钮的原因。我现在用的是搜索接口在我的活动。我不继的EditText /文本字段的方法。

EDIT 2: The reason why I ask is because I want to have a software button showing in my UI if the device is not equipped with a hardware button. I am using the searchable interface in my activity. I am not following the EditText / TextField approach.

推荐答案

我不认为你需要检测，如果它确实有一个搜索硬件按钮。该框架将帮助你在这里（不过，我敢肯定，一旦冰淇淋三明治发布这一过程将被简化）

I don't think you need to detect if it actually has a search hardware button. The framework will help you out here (though, I'm sure this process will be simplified once Ice Cream Sandwich is released)

目前，这不会有硬件搜索的唯一设备是蜂窝片。因此，通过使用安卓targetSdkVersion =11（或更高版本），加入实现OnQueryTextListener 您片段或活动，再加入类似：

Currently, the only devices that won't have hardware search are Honeycomb tablets. So, by using android:targetSdkVersion="11" (or higher), adding implements OnQueryTextListener to your Fragment or Activity, and then adding something like:

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.notebooks_menu, menu);
    final SearchView sv = new SearchView(getActivity());
    sv.setOnQueryTextListener(this);
    menu.findItem(R.id.search_notebooks).setActionView(sv);
}

您将主要解决的问题。现在，得到它的工作在pre-蜂窝设备，您可能需要使用兼容库，或使用反射或在code一些其他的后卫。

You will essentially solve the problem. Now, to get it working on pre-Honeycomb devices, you may need to use the compatibility library, or use reflection or some other guards in your code.

修改

三星Galaxy S II并没有一个专门的硬件搜索按钮，但是如果你的按住MENU按钮几秒钟，就开始作为一个硬件搜索按钮。的

The Samsung Galaxy S II does not have a dedicated hardware search button, but if you hold the menu button down for a couple of seconds, it will begin acting as a hardware search button.
