Android屏幕适配(底部虚拟按键)

先上图：

可以发现，虚拟键位，挡住了取消按钮的触控区域，网上百度一下，大多是在布局内家加上（Android:fitsSystemWindows=”true”）　，ＢＵＴ我的控件不是布局，里面写好的啊！我采用的自定义布局，SO 问题就是如何让取消按钮的触控区域显示出来。

解决办法：获取虚拟键高度，然后定位显示布局的位置

public static Point getNavigationBarSize(Context context) { Point appUsableSize = getAppUsableScreenSize(context); Point realScreenSize = getRealScreenSize(context); // navigation bar on the right if (appUsableSize.x < realScreenSize.x) { return new Point(realScreenSize.x - appUsableSize.x, appUsableSize.y); } // navigation bar at the bottom if (appUsableSize.y < realScreenSize.y) { return new Point(appUsableSize.x, realScreenSize.y - appUsableSize.y); } // navigation bar is not present return new Point(); } public static Point getAppUsableScreenSize(Context context) { WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); Display display = windowManager.getDefaultDisplay(); Point size = new Point(); display.getSize(size); return size; } public static Point getRealScreenSize(Context context) { WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); Display display = windowManager.getDefaultDisplay(); Point size = new Point(); if (Build.VERSION.SDK_INT >= 17) { display.getRealSize(size); } else if (Build.VERSION.SDK_INT >= 14) { try { size.x = (Integer) Display.class.getMethod("getRawWidth").invoke(display); size.y = (Integer) Display.class.getMethod("getRawHeight").invoke(display); } catch (IllegalAccessException e) {} catch (InvocationTargetException e) {} catch (NoSuchMethodException e) {} } return size; }
