在Android中获取屏幕宽度和高度

Question

如何获取屏幕宽度和高度并在以下位置使用此值：

@Override protected void onMeasure(int widthSpecId, int heightSpecId) {
    Log.e(TAG, "onMeasure" + widthSpecId);
    setMeasuredDimension(SCREEN_WIDTH, SCREEN_HEIGHT - 
        game.findViewById(R.id.flag).getHeight());
}

Answer 1

使用此代码，您可以获得运行时显示的宽度和高度：

DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int height = displayMetrics.heightPixels;
int width = displayMetrics.widthPixels;

在视图中，您需要执行以下操作：

((Activity) getContext()).getWindowManager()
                         .getDefaultDisplay()
                         .getMetrics(displayMetrics);

在某些情况下，设备有导航栏，您必须在运行时检查：

public boolean showNavigationBar(Resources resources)
{
    int id = resources.getIdentifier("config_showNavigationBar", "bool", "android");
    return id > 0 && resources.getBoolean(id);
}

如果设备有导航栏，则计算其高度：

private int getNavigationBarHeight() {
    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;
}

所以设备的最终高度是：

int height = displayMetrics.heightPixels + getNavigationBarHeight();

Answer 2

public class DisplayInfo {
    int screen_height=0, screen_width=0;
    WindowManager wm;
    DisplayMetrics displaymetrics;

    DisplayInfo(Context context) {
        getdisplayheightWidth(context);
    }

    void getdisplayheightWidth(Context context) {
        wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
        displaymetrics = new DisplayMetrics();
        wm.getDefaultDisplay().getMetrics(displaymetrics);
        screen_height = displaymetrics.heightPixels;
        screen_width = displaymetrics.widthPixels;
    }

    public int getScreen_height() {
        return screen_height;
    }

    public int getScreen_width() {
        return screen_width;
    }
}

Answer 3

此处显示的方法已弃用/过时但仍在使用。需要获取API 13

看看这个

Display disp= getWindowManager().getDefaultDisplay();
Point dimensions = new Point();
disp.getSize(size);
int width = size.x;
int height = size.y;

Answer 4

Display display = ((WindowManager) this.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int mWidthScreen = display.getWidth();
int mHeightScreen = display.getHeight();

Answer 5

完整的方法，它返回真正的解决方案：

            WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            Point size = new Point();
            wm.getDefaultDisplay().getRealSize(size);
            final int width = size.x, height = size.y;

因为这可以在不同的方向上改变，所以这是一个解决方案（在Kotlin中），无论方向如何都要正确：

/**
 * returns the natural orientation of the device: Configuration.ORIENTATION_LANDSCAPE or Configuration.ORIENTATION_PORTRAIT .<br></br>
 * The result should be consistent no matter the orientation of the device
 */
@JvmStatic
fun getScreenNaturalOrientation(context: Context): Int {
    //based on : http://stackoverflow.com/a/9888357/878126
    val windowManager = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager
    val config = context.resources.configuration
    val rotation = windowManager.defaultDisplay.rotation
    return if ((rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) && config.orientation == Configuration.ORIENTATION_LANDSCAPE || (rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270) && config.orientation == Configuration.ORIENTATION_PORTRAIT)
        Configuration.ORIENTATION_LANDSCAPE
    else
        Configuration.ORIENTATION_PORTRAIT
}

/**
 * returns the natural screen size (in pixels). The result should be consistent no matter the orientation of the device
 */
@JvmStatic
fun getScreenNaturalSize(context: Context): Point {
    val screenNaturalOrientation = getScreenNaturalOrientation(context)
    val wm = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager
    val point = Point()
    wm.defaultDisplay.getRealSize(point)
    val currentOrientation = context.resources.configuration.orientation
    if (currentOrientation == screenNaturalOrientation)
        return point
    else return Point(point.y, point.x)
}

Answer 6

这里没有任何答案适用于Chrome OS多显示器或即将推出的可折叠显示器。

查找当前配置时，请始终使用getResources().getConfiguration()中当前活动的配置。请勿使用后台活动中的配置或系统资源中的配置。后台活动没有大小，系统的配置可能包含多个具有相互冲突的大小和方向的窗口，因此无法提取可用的数据。

所以答案是

val config = context.getResources().getConfiguration()
val (screenWidthPx, screenHeightPx) = config.screenWidthDp.dp to config.screenHeightDp.dp

Answer 7

对于kotlin用户

fun Activity.displayMetrics(): DisplayMetrics {
   val displayMetrics = DisplayMetrics();
   windowManager.defaultDisplay.getMetrics(displayMetrics);
   return displayMetrics
}

在Activity中你可以像使用它一样

    displayMetrics().let { displayMetrics -> 
        val height = displayMetrics.heightPixels
        val width = displayMetrics.widthPixels
    }

或者片段化

    activity?.displayMetrics()?.run {
        val height = heightPixels
        val width = widthPixels
    }

Answer 8

只需使用下面的函数返回屏幕大小的宽度和高度作为整数数组

private int[] getScreenSIze(){
        DisplayMetrics displaymetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int h = displaymetrics.heightPixels;
        int w = displaymetrics.widthPixels;

        int[] size={w,h};
        return size;

    }

在onCreate功能或按钮上单击添加以下代码以输出屏幕尺寸，如下所示

 int[] screenSize= getScreenSIze();
        int width=screenSize[0];
        int height=screenSize[1];
        screenSizes.setText("Phone Screen sizes \n\n  width = "+width+" \n Height = "+height);

Answer 9

我在本页中找到了weigan的最佳答案，以下是如何在Xamarin.Android中使用它：

public int GetScreenWidth()
{
    return Resources.System.DisplayMetrics.WidthPixels;
}

public int GetScreenHeight()
{
    return Resources.System.DisplayMetrics.HeightPixels;
}

Answer 10

屏幕分辨率是屏幕中像素的总数。以下程序将提取设备的屏幕分辨率。它将打印屏幕宽度和高度。这些值以像素为单位。

public static Point getScreenResolution(Context context) {
// get window managers
WindowManager manager =  (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);
Display display = manager.getDefaultDisplay();
Point point = new Point();
display.getSize(point);

 // get width and height
 int width = point.x;
 int height = point.y;

 return point;

}

Answer 11

这个set of utilities可以在Android中使用Size抽象。

它包含一个类SizeFromDisplay.java您可以像这样使用它：

ISize size = new SizeFromDisplay(getWindowManager().getDefaultDisplay());
size.width();
size.hight();

Answer 12

有一个非常简单的答案，没有传递上下文

public static int getScreenWidth() {
    return Resources.getSystem().getDisplayMetrics().widthPixels;
}

public static int getScreenHeight() {
    return Resources.getSystem().getDisplayMetrics().heightPixels;
}

注意：如果您想要高度包含导航栏，请使用以下方法

WindowManager windowManager =
        (WindowManager) BaseApplication.getApplication().getSystemService(Context.WINDOW_SERVICE);
    final Display display = windowManager.getDefaultDisplay();
    Point outPoint = new Point();
    if (Build.VERSION.SDK_INT >= 19) {
        // include navigation bar
        display.getRealSize(outPoint);
    } else {
        // exclude navigation bar
        display.getSize(outPoint);
    }
    if (outPoint.y > outPoint.x) {
        mRealSizeHeight = outPoint.y;
        mRealSizeWidth = outPoint.x;
    } else {
        mRealSizeHeight = outPoint.x;
        mRealSizeWidth = outPoint.y;
    }

Answer 13

两个步骤。首先，扩展Activity类

class Example extends Activity

第二：使用此代码

 DisplayMetrics displayMetrics = new DisplayMetrics();
 WindowManager windowmanager = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
 windowmanager.getDefaultDisplay().getMetrics(displayMetrics);
 int deviceWidth = displayMetrics.widthPixels;
 int deviceHeight = displayMetrics.heightPixels;

Answer 14

试试Kotlin的这个代码

 val display = windowManager.defaultDisplay
 val size = Point()
 display.getSize(size)
 var DEVICE_WIDTH = size.x
 var DEVICE_HEIGHT = size.y

Answer 15

    int getScreenSize() {
        int screenSize = getResources().getConfiguration().screenLayout &
                Configuration.SCREENLAYOUT_SIZE_MASK;
//        String toastMsg = "Screen size is neither large, normal or small";
        Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
        int orientation = display.getRotation();

        int i = 0;

                    // TODO: add logic for landscape mode here
                    i = 2;
                } else {
                    i = 1;
                }


                break;
            case Configuration.SCREENLAYOUT_SIZE_XLARGE:
                if (orientation == Surface.ROTATION_90
                        || orientation == Surface.ROTATION_270) {
                    // TODO: add logic for landscape mode here
                    i = 4;
                } else {
                    i = 3;
                }

                break;


        }
//        customeToast(toastMsg);
        return i;
    }

Answer 16

       @Override
        protected void onPostExecute(Drawable result) {
            Log.d("width",""+result.getIntrinsicWidth());
            urlDrawable.setBounds(0, 0, 0+result.getIntrinsicWidth(), 600);

            // change the reference of the current drawable to the result
            // from the HTTP call
            urlDrawable.drawable = result;

            // redraw the image by invalidating the container
            URLImageParser.this.container.invalidate();

            // For ICS
            URLImageParser.this.container.setHeight((400+URLImageParser.this.container.getHeight()
                    + result.getIntrinsicHeight()));

            // Pre ICS`enter code here`
            URLImageParser.this.container.setEllipsize(null);
        }

Answer 17

只是为了更新parag和SpK的答案，以便与不推荐使用的方法的当前SDK向后兼容性保持一致：

int Measuredwidth = 0;  
int Measuredheight = 0;  
Point size = new Point();
WindowManager w = getWindowManager();

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)    {
    w.getDefaultDisplay().getSize(size);
    Measuredwidth = size.x;
    Measuredheight = size.y; 
}else{
    Display d = w.getDefaultDisplay(); 
    Measuredwidth = d.getWidth(); 
    Measuredheight = d.getHeight(); 
}

Answer 18

为什么不

DisplayMetrics displaymetrics = getResources（）。getDisplayMetrics（）;

然后用

displayMetrics.widthPixels（heightPixels）

Answer 19

尝试以下代码： -

1.

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

2.

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();  // deprecated
int height = display.getHeight();  // deprecated

要么

int width = getWindowManager().getDefaultDisplay().getWidth(); 
int height = getWindowManager().getDefaultDisplay().getHeight();

3.

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);

metrics.heightPixels;
metrics.widthPixels;

Answer 20

进入Android非常容易：

int width  = Resources.getSystem().getDisplayMetrics().widthPixels;
int height = Resources.getSystem().getDisplayMetrics().heightPixels;
