屏幕高度，不包括状态栏，actionBar和选项卡 [英] Height of screen without status bar, actionBar and tabs

问题描述

我有一个ListView，我希望每一行都填充可用屏幕的三分之一.我有可见的状态栏，然后是一个带有滑动标签的actionBar.我正在像这样进行当前计算:

I have a ListView that I want each row to fill a third of the available screen. I have the status bar visible, and then an actionBar with slidingTabs beneath. I'm doing the current calculation like this:

height = context.getResources().getDisplayMetrics().heightPixels;
if (context.getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
    {
        actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,context.getResources().getDisplayMetrics());
        Log.d("actionBarHeigth", actionBarHeight.toString());
    }

并按如下所示设置视图高度:

And setting the views height like this:

holder.imageView.getLayoutParams().height = (height - actionBarHeight*2) / 3;

但是列表的行有点太大，我想这是导致它的状态栏.如何将其高度添加到计算中?

But the rows of the list are slightly too big, and i guess it's the status bar causing it. How can I add the height of it to my calculations?

推荐答案

基于@rasmeta的回答，我编写了此代码，并且成功了.现在，我的行正好是可用屏幕的三分之一.这是获取状态栏高度的方法:

Based on @rasmeta 's answer I made this code and it does the trick. My rows are now exactly a third of the available screen. Here is how to get the height of the status bar:

int resource = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resource > 0) {
        statusBarHeight = context.getResources().getDimensionPixelSize(resource);
    }

每行高度的计算如下:

holder.imageView.getLayoutParams().height = (screenHeight - statusBarHeight - actionBarHeight*2) / 3;
// actionBarHeight * 2 because the tabs have the same height as the actionBar.
