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>
