项目要求 滑动图片卡，背景会自动变色，并且动态修改状态栏沉浸色
关键代码 ：
在图片切换的回调接口中
执行
Bitmap bit = drawableToBitmap(resource); int pixel = bit.getPixel(resource.getIntrinsicWidth()/ 2,0);//取图片最上面的中间色图 int redValue = Color.red(pixel); int blueValue = Color.blue(pixel); int greenValue = Color.green(pixel); int alpha = Color.alpha(pixel); StatusBarCompat.compat(getActivity(), Color.argb(alpha, redValue, greenValue, blueValue));//StatusBarCompat为修改状态栏工具类
public class StatusBarCompat { private static final int INVALID_VAL = -1; private static final int COLOR_DEFAULT = Color.parseColor("#00000000"); public static void compat(Activity activity, int statusColor) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { if (statusColor != INVALID_VAL) { activity.getWindow().setStatusBarColor(statusColor); } return; } if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) { int color = COLOR_DEFAULT; ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content); if (statusColor != INVALID_VAL) { color = statusColor; } statusBarView = new View(activity); ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(activity)); statusBarView.setBackgroundColor(color); contentView.addView(statusBarView, lp); } } public static void Clean(Activity activity, int statusColor) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) { ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content); contentView.removeView(statusBarView); } if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { activity.getWindow().setStatusBarColor(statusColor); } } private static View statusBarView; public static void compat(Activity activity) { compat(activity, INVALID_VAL); } public static int getStatusBarHeight(Context context) { int result = 0; int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android"); if (resourceId > 0) { result = context.getResources().getDimensionPixelSize(resourceId); } return result; } } StatusBarCompat工具类取自网络，在其基础上加了Clean方法，其原因因为fragment基于activity，修改单个fragment状态栏，其它fragment状态栏也会变色。。 要求只修改 图片卡这个fragment的状态栏，其他fragment的状态栏 都为fragment白色默认色，在图片卡这个fragment中
public void onPause() { super.onPause(); StatusBarCompat.Clean(getActivity(),Color.WHITE); }
