5.0以上效果如下：

/**
     * 安卓5.0以上版本设置状态栏颜色配合如下两条属性使用
     * android:clipToPadding="true"
     * android:fitsSystemWindows="true"
     * @param activity

                    | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

//            window.setNavigationBarColor(Color.TRANSPARENT);
        }
    }

    /**

        }

        SystemBarTintManager tintManager = new SystemBarTintManager(activity);
        tintManager.setStatusBarTintEnabled(true);
        // 使用颜色资源
        tintManager.setStatusBarTintResource(R.color.blue);
    }

    @TargetApi(19)

    private static void setTranslucentStatus(Activity activity, boolean on) {

        Window win = activity.getWindow();

        WindowManager.LayoutParams winParams = win.getAttributes();

        final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;

        if (on) {

            winParams.flags |= bits;

        } else {

            winParams.flags &= ~bits;

        }
        win.setAttributes(winParams);
    }

在Activity的onCreate方法中调用即可
