我如何获得Android屏幕的高度?(How do I get the height of the screen in Android?)

我怎样才能在Android中获得屏幕的可用高度? 我需要高度减去状态栏/菜单栏或任何其他可能在屏幕上的装饰,我需要它适用于所有设备。 另外,我需要在onCreate函数中了解这一点。 我知道这个问题以前已经问过,但我已经尝试过他们的解决方案,而且他们都没有工作。 以下是我尝试过的一些事情:

这不考虑状态栏/菜单栏:

Display display = getWindowManager().getDefaultDisplay();
screenWidth = display.getWidth();
screenHeight = display.getHeight();

这也不是:

Point size = new Point();
getWindowManager().getDefaultDisplay().getSize(size);
screenWidth = size.x;
screenHeight = size.y;

不是这样的:

Point size = new Point();
getWindowManager().getDefaultDisplay().getRealSize(size);
screenWidth = size.x;
screenHeight = size.y;

这不起作用:

Display display = getWindowManager().getDefaultDisplay();
DisplayMetrics metrics = new DisplayMetrics();
display.getMetrics(metrics);
// since SDK_INT = 1;
screenWidth = metrics.widthPixels;
screenHeight = metrics.heightPixels;
try
{
    // used when 17 > SDK_INT >= 14; includes window decorations (statusbar bar/menu bar)
    screenWidth = (Integer) Display.class.getMethod("getRawWidth").invoke(display);
    screenHeight = (Integer) Display.class.getMethod("getRawHeight").invoke(display);
}
catch (Exception ignored)
{
    // Do nothing
}
try
{
    // used when SDK_INT >= 17; includes window decorations (statusbar bar/menu bar)
    Point realSize = new Point();
    Display.class.getMethod("getRealSize", Point.class).invoke(display, realSize);
    screenWidth = realSize.x;
    screenHeight = realSize.y;
}
catch (Exception ignored)
{
    // Do nothing
}

然后我使用下面的代码从屏幕高度中减去状态栏和菜单栏的高度:

int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0)
    result = getResources().getDimensionPixelSize(resourceId);
screenHeight -= result;
result = 0;
if (screenHeight >= screenWidth)
    resourceId = getResources().getIdentifier("navigation_bar_height", "dimen", "android");
else
    resourceId = getResources().getIdentifier("navigation_bar_height_landscape", "dimen", "android");
if (resourceId > 0)
    result = getResources().getDimensionPixelSize(resourceId);
screenHeight -= result;

在API 17上,它可以正确计算纵向状态栏和菜单栏的高度,而不是横向。 在API 10上,它返回0.我需要它在所有设备或最低API 10上理想地工作。


How can I get the available height of the screen in Android? I need to the height minus the status bar / menu bar or any other decorations that might be on screen and I need it to work for all devices. Also, I need to know this in the onCreate function. I know this question has been asked before but I have already tried their solutions and none of them work. Here are some of the things I have tried:

This does not take into account the status bar / menu bar:

Display display = getWindowManager().getDefaultDisplay();
screenWidth = display.getWidth();
screenHeight = display.getHeight();

Neither does this:

Point size = new Point();
getWindowManager().getDefaultDisplay().getSize(size);
screenWidth = size.x;
screenHeight = size.y;

Nor this:

Point size = new Point();
getWindowManager().getDefaultDisplay().getRealSize(size);
screenWidth = size.x;
screenHeight = size.y;

This does not work:

Display display = getWindowManager().getDefaultDisplay();
DisplayMetrics metrics = new DisplayMetrics();
display.getMetrics(metrics);
// since SDK_INT = 1;
screenWidth = metrics.widthPixels;
screenHeight = metrics.heightPixels;
try
{
    // used when 17 > SDK_INT >= 14; includes window decorations (statusbar bar/menu bar)
    screenWidth = (Integer) Display.class.getMethod("getRawWidth").invoke(display);
    screenHeight = (Integer) Display.class.getMethod("getRawHeight").invoke(display);
}
catch (Exception ignored)
{
    // Do nothing
}
try
{
    // used when SDK_INT >= 17; includes window decorations (statusbar bar/menu bar)
    Point realSize = new Point();
    Display.class.getMethod("getRealSize", Point.class).invoke(display, realSize);
    screenWidth = realSize.x;
    screenHeight = realSize.y;
}
catch (Exception ignored)
{
    // Do nothing
}

I then used the following code to subtract the height of the status bar and menu bar from the screen height:

int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0)
    result = getResources().getDimensionPixelSize(resourceId);
screenHeight -= result;
result = 0;
if (screenHeight >= screenWidth)
    resourceId = getResources().getIdentifier("navigation_bar_height", "dimen", "android");
else
    resourceId = getResources().getIdentifier("navigation_bar_height_landscape", "dimen", "android");
if (resourceId > 0)
    result = getResources().getDimensionPixelSize(resourceId);
screenHeight -= result;

On API 17 it gives it correctly calculates the height of the status bar and menu bar in portrait but not in landscape. On API 10, it returns 0. I need it to work ideally on all devices or minimum API 10.

显然,当你想从远程存储库下载maven插件时 - 与标准artifcat相反,你必须在你的pom中定义一个特殊的pluginRepositories部分; 一个简单的存储库声明将被忽略。

  <pluginRepositories>
        <pluginRepository>
            <id>Nexus Codehaus</id>
            <url>http://nexus.codehaus.org/snapshots/</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </pluginRepository>
    </pluginRepositories>

Apparently when you want to download a maven plugin from a remote repository -as opposed to a standard artifcat, you have to define a special pluginRepositories section in your pom; a plain Repository declaration will just be ignored.

  <pluginRepositories>
        <pluginRepository>
            <id>Nexus Codehaus</id>
            <url>http://nexus.codehaus.org/snapshots/</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </pluginRepository>
    </pluginRepositories>
