Android自定义修改状态栏（字体颜色均可修改）

状态栏

在一些安卓app中，我们会发现app界面上方状态栏的字体和颜色与手机待机时不一样，难道系统会根据背景去主动变色？？答案当然是否定的，系统绝对不会根据背景去主动变色。而是需要我们去手动改变系统状态栏的背景和字体颜色。之前接到一个需求就是要求系统状态栏改变，然后就在网上找了一些所谓的可以改变的文章，试了之后发现没有什么卵用。最后在多篇文章中找到了一些可用的类，然后自己组合了一下，发现可以达到需要的结果。特此记录，方便大家指导和后续使用。

首先看看对比效果：

右图中的就是改过的样式，看起来和谐了一点是吧，，，，

activity调用很简单。共两行：

StatusBarCompat.translucentStatusBar(activity, false);StatusBarUtil.setImmersiveStatusBar(activity, true);

StatusBarCompat类。先判断版本号，然后根据版本号调用不同的版本去处理状态栏。全码如下：

package .systembar;import android.annotation.TargetApi;import android.app.Activity;import android.content.Context;import android.os.Build;import android.support.design.widget.AppBarLayout;import android.support.design.widget.CollapsingToolbarLayout;import android.support.design.widget.CoordinatorLayout;import android.support.v4.view.ViewCompat;import android.support.v7.widget.Toolbar;import android.view.Gravity;import android.view.View;import android.view.ViewGroup;import android.view.Window;import android.view.WindowManager;import android.widget.FrameLayout;/*** After kitkat add fake status bar* Created by qiu on 8/27/16.*/@TargetApi(Build.VERSION_CODES.KITKAT)class StatusBarCompatKitKat {private static final String TAG_FAKE_STATUS_BAR_VIEW = "statusBarView";private static final String TAG_MARGIN_ADDED = "marginAdded";/*** return statusBar's Height in pixels*/private static int getStatusBarHeight(Context context) {int result = 0;int resId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");if (resId > 0) {result = context.getResources().getDimensionPixelOffset(resId);}return result;}/*** 1.

mStatusBarView;}/*** use reserved order to remove is more quickly.*/private static void removeFakeStatusBarViewIfExist(Activity activity) {Window window = activity.getWindow();ViewGroup mDecorView =

注：找不到的类可在源码中复制，这里就不写了，有点多。

StatusBarUtil类。同样是根据版本号去使用不同的方式去处理。全码如下：
