在android6.0中，状态栏的高度为24dp

 <!-- Height of the status bar -->
 <dimen name="status_bar_height">24dp</dimen>
 <!-- Height of the bottom navigation / system bar. -->
 <dimen name="navigation_bar_height">48dp</dimen>

你可以在源代码中找到答案:frameworks\base\core\res\res\values\ dimensions .xml

240x320 - 20px 320x480 - 25px 480x800+ - 38px

在MDPI设备上，状态栏是25px。我们可以将其作为基础，并将其乘以密度(四舍五入)来获得任何设备上的状态栏高度:

int statusBarHeight = Math.ceil(25 * context.getResources().getDisplayMetrics().density);

参考参数:ldpi=。75, mdpi=1, hdpi=1.5, xhdpi=2

根据材料指南;状态栏高度为24dp。

如果你想获得状态栏的高度，你可以使用下面的方法:

private static int statusBarHeight(android.content.res.Resources res) {
    return (int) (24 * res.getDisplayMetrics().density);
}

可以从activity中调用:

statusBarHeight(getResources());

我有同样的问题，必须在onCreate中获得状态栏的高度。这对我很有用。

private static final int LOW_DPI_STATUS_BAR_HEIGHT = 19;

private static final int MEDIUM_DPI_STATUS_BAR_HEIGHT = 25;

private static final int HIGH_DPI_STATUS_BAR_HEIGHT = 38;

在onCreate内部:

DisplayMetrics displayMetrics = new DisplayMetrics();
((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getMetrics(displayMetrics);

int statusBarHeight;

switch (displayMetrics.densityDpi) {
    case DisplayMetrics.DENSITY_HIGH:
        statusBarHeight = HIGH_DPI_STATUS_BAR_HEIGHT;
        break;
    case DisplayMetrics.DENSITY_MEDIUM:
        statusBarHeight = MEDIUM_DPI_STATUS_BAR_HEIGHT;
        break;
    case DisplayMetrics.DENSITY_LOW:
        statusBarHeight = LOW_DPI_STATUS_BAR_HEIGHT;
        break;
    default:
        statusBarHeight = MEDIUM_DPI_STATUS_BAR_HEIGHT;
}

感谢@Niklas +1，这是正确的方法。

public class MyActivity extends Activity implements android.support.v4.View.OnApplyWindowInsetsListener {

    Rect windowInsets;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.my_activity);

        View rootview = findViewById(android.R.id.content);

        android.support.v4.View.ViewCompat.setOnApplyWindowInsetsListener(rootview, this);
    }

    android.support.v4.View.WindowInsetsCompat android.support.v4.View.OnApplyWindowInsetsListener.OnApplyWindowInsets(View v, android.support.v4.View.WindowInsetsCompat insets)
    {
        windowInsets = new Rect();
        windowInsets.set(insets.getSystemWindowInsetLeft(), insets.getSystemWindowInsetTop(), insets.getSystemWindowInsetRight(), insets.getSystemWindowInsetBottom());
        //StatusBarHeight = insets.getSystemWindowInsetTop();

        //Refresh/Adjust view accordingly

        return insets;
    }
}

请原谅，如果代码不是100%正确，从Xamarin c#转换，但这是它的公正。工作与缺口等。
