软按钮栏尺寸 [英] Dimension of soft buttons bar

问题描述

有没有一种方法来确定设备没有硬菜单按钮在菜单栏的尺寸（宽）？ （如ARCHOS设备）。

Is there a way to determine the dimension (width) of the menu bar of devices without hard menu buttons? (like the archos devices).

我需要知道屏幕的可用尺寸...

I need to know the usable dimension of the screen...

谢谢， Direz

推荐答案

这个方法是为了设置在Android的奇巧布局填充（4.4）非常有用。用这种方法，就可以避免软按钮栏重叠在你的布局。

This method is very useful in order to set the layout padding in Android KitKat (4.4). Using this, you can avoid the soft buttons bar overlapping over your layout.

在 getRealMetrics 方法仅适用于API 17 +，但我只用下面的方法我写的设备上的API 19 +

The getRealMetrics method is only available with API 17 and +, but I'm only using the following method I wrote for devices on API 19+

@SuppressLint("NewApi")
private int getSoftbuttonsbarHeight() {
    // getRealMetrics is only available with API 17 and +
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        DisplayMetrics metrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metrics);
        int usableHeight = metrics.heightPixels;
        getWindowManager().getDefaultDisplay().getRealMetrics(metrics);
        int realHeight = metrics.heightPixels;
        if (realHeight > usableHeight)
            return realHeight - usableHeight;
        else
            return 0;
    }
    return 0;
}
