Android 获取屏幕的多种宽高信息的示例代码

本文主要介绍了Android 获取屏幕的多种宽高信息的示例代码，分享给大家，具体如下：

包含的宽高信息如下图所示：

在模拟器上获取到的数据：

08-26 07:19:32.712 7834-7834/com.czy.screeninfo E/MainActivity: getTotalScreenHeight 1920
08-26 07:19:33.505 7834-7834/com.czy.screeninfo E/MainActivity: getScreenWidth 1080
08-26 07:19:34.211 7834-7834/com.czy.screeninfo E/MainActivity: getAvailableScreenHeight 1794
08-26 07:19:34.979 7834-7834/com.czy.screeninfo E/MainActivity: getStatusBarHeight 63
08-26 07:19:35.580 7834-7834/com.czy.screeninfo E/MainActivity: getVirtualBarHeightIfRoom 126
08-26 07:19:36.340 7834-7834/com.czy.screeninfo E/MainActivity: getVirtualBarHeight 126
08-26 07:19:37.048 7834-7834/com.czy.screeninfo E/MainActivity: getTitleHeight 147

具体的代码：

public class ScreenUtils {    public static int getTotalScreenHeight(Activity activity) {    DisplayMetrics displayMetrics = new DisplayMetrics();    activity.getWindowManager().getDefaultDisplay().getRealMetrics(displayMetrics);    return displayMetrics.heightPixels;  }    public static int getScreenWidth(Activity activity) {    DisplayMetrics displayMetrics = new DisplayMetrics();    activity.getWindowManager().getDefaultDisplay().getRealMetrics(displayMetrics);    return displayMetrics.widthPixels;  }    public static int getAvailableScreenHeight(Activity activity) {    DisplayMetrics displayMetrics = new DisplayMetrics();    activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);    return displayMetrics.heightPixels;  }    public static int getStatusBarHeight(Activity activity) {    int resourceId = activity.getResources().getIdentifier("status_bar_height", "dimen", "android");    return activity.getResources().getDimensionPixelSize(resourceId);  }    public static int getVirtualBarHeightIfRoom(Activity activity) {    DisplayMetrics displayMetrics = new DisplayMetrics();    activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);    int usableHeight = displayMetrics.heightPixels;    activity.getWindowManager().getDefaultDisplay().getRealMetrics(displayMetrics);    int realHeight = displayMetrics.heightPixels;    return realHeight - usableHeight;  }    public static int getVirtualBarHeight(Activity activity) {    int resourceId = activity.getResources().getIdentifier("navigation_bar_height", "dimen", "android");    return activity.getResources().getDimensionPixelSize(resourceId);  }    public static int getTitleHeight(Activity activity) {    return activity.getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();  }    public static int dp2px(Context context, float dpValue) {    float scale = context.getResources().getDisplayMetrics().density;    return (int) (dpValue * scale + 0.5f);  }    public static int px2dp(Context context, float pxValue) {    float scale = context.getResources().getDisplayMetrics().density;    return (int) (pxValue / scale + 0.5f);  }}
