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);
  }

}
