获取Android设备屏幕大小
1.Java 代码
Android获取屏幕宽度与长度的五个方法 (taodudu.cc) 存在的问题 ：获取到的数据 只是屏幕大小 没有包含系统导航栏的高度/宽度。
解决方法：使用 WindowMetrics
public void getScreenParams(){ WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE); if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.R) { WindowMetrics currentWindowMetrics = wm.getCurrentWindowMetrics(); int width = currentWindowMetrics.getBounds().width(); int height = currentWindowMetrics.getBounds().height(); screenInfo.setText("屏幕分辨率为："+width+"*"+height); Log.e(getClass().getName(),"screen width:"+width+" screen height:"+height); }else { int width = wm.getDefaultDisplay().getWidth(); int height = wm.getDefaultDisplay().getHeight(); screenInfo.setText("屏幕分辨率为："+width+"*"+height); Log.e(getClass().getName(),"screen width:"+width+" screen height:"+height); } // // // DisplayMetrics dm = new DisplayMetrics(); // // getWindowManager().getDefaultDisplay().getMetrics(dm); // int mScreenWidth = dm.widthPixels;// 获取屏幕分辨率宽度 // int mScreenHeight = dm.heightPixels; // // Log.e(getClass().getName(),"screen width:"+mScreenWidth+" screen height:"+mScreenHeight); // // int mScreenWidth1 = getResources().getDisplayMetrics().widthPixels; // // int mScreenHeight1 = getResources().getDisplayMetrics().heightPixels; // // Log.e(getClass().getName(),"screen width:"+mScreenWidth1+" screen height:"+mScreenHeight1); }
2.adb 命令
wm 命令
adb shell wm usage: wm [subcommand] [options] wm size [reset|WxH] wm density [reset|DENSITY] wm overscan [reset|LEFT,TOP,RIGHT,BOTTOM]

3.获取导航栏高度
public static int getStatusBarHeight(Context context) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) { WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); WindowMetrics windowMetrics = wm.getCurrentWindowMetrics(); WindowInsets windowInsets = windowMetrics.getWindowInsets(); Insets insets = windowInsets.getInsetsIgnoringVisibility(WindowInsets.Type.navigationBars() | WindowInsets.Type.displayCutout()); return insets.bottom; } .... }
getInsetsIgnoringVisibility
