Android实现修改状态栏背景、字体和图标颜色的方法

前言:

android开发,对于状态栏的修改,实在是不友好,没什么api可以用,不像ios那么方便.但是ui又喜欢只搞ios一套.没办法.各种翻源码,写反射.真的蛋疼.

需求场景:

当toolbar及状态栏需要为白色或浅色时(如简书),状态栏由于用的light风格theme,字体,图标也都是白色,会看不清.如果改变成黑色就很和谐了.

一.修改状态栏颜色:

改变状态栏颜色,可以看看这篇文章.传送门:

传送门实现的效果:

这种方法实现的状态栏变色,没有黑色背景.

使用全屏模式实现的效果如下(qq的效果):

很明显的黑色背景.

我用的手机是华为,系统7.0

二.修改状态栏字体:

通用工具类:

public class statusbarutil {

  /**
   * 设置状态栏黑色字体图标，
   * 适配4.4以上版本miuiv、flyme和6.0以上版本其他android
   *
   * @return 1:miuui 2:flyme 3:android6.0
   */
  public static int getstatusbarlightmode(window window) {
    int result = 0;
    if (build.version.sdk_int >= build.version_codes.kitkat) {
      if (miuisetstatusbarlightmode(window, true)) {
        result = 1;
      } else if (flymesetstatusbarlightmode(window, true)) {
        result = 2;
      } else if (build.version.sdk_int >= build.version_codes.m) {
        window.getdecorview().setsystemuivisibility(view.system_ui_flag_light_status_bar);
        result = 3;
      } else {//5.0

      }
    }
    return result;
  }

  /**
   * 已知系统类型时，设置状态栏黑色字体图标。
   * 适配4.4以上版本miuiv、flyme和6.0以上版本其他android
   */
  public static void setstatusbarlightmode(window window) {
    int type = getstatusbarlightmode(window);
    if (type == 1) {
      miuisetstatusbarlightmode(window, true);
    } else if (type == 2) {
      flymesetstatusbarlightmode(window, true);
    } else if (type == 3) {
      window.getdecorview().setsystemuivisibility(view.system_ui_flag_light_status_bar);
    } else {//5.0
      
    }
  }

  /**
   * 清除miui或flyme或6.0以上版本状态栏黑色字体
   */
  public static void statusbardarkmode(window window) {
    int type = getstatusbarlightmode(window);
    if (type == 1) {
      miuisetstatusbarlightmode(window, false);
    } else if (type == 2) {
      flymesetstatusbarlightmode(window, false);
    } else if (type == 3) {
      window.getdecorview().setsystemuivisibility(view.system_ui_flag_visible);
    }

  }

  /**
   * 设置状态栏图标为深色和魅族特定的文字风格
   * 可以用来判断是否为flyme用户
   *
   * @param window 需要设置的窗口
   * @param dark  是否把状态栏字体及图标颜色设置为深色
   * @return boolean 成功执行返回true
   */
  public static boolean flymesetstatusbarlightmode(window window, boolean dark) {
    boolean result = false;
    if (window != null) {
      try {
        windowmanager.layoutparams lp = window.getattributes();
        field darkflag = windowmanager.layoutparams.class
            .getdeclaredfield("meizu_flag_dark_status_bar_icon");
        field meizuflags = windowmanager.layoutparams.class
            .getdeclaredfield("meizuflags");
        darkflag.setaccessible(true);
        meizuflags.setaccessible(true);
        int bit = darkflag.getint(null);
        int value = meizuflags.getint(lp);
        if (dark) {
          value |= bit;
        } else {
          value &= ~bit;
        }
        meizuflags.setint(lp, value);
        window.setattributes(lp);
        result = true;
      } catch (exception e) {

      }
    }
    return result;
  }

  /**
   * 设置状态栏字体图标为深色，需要miuiv6以上
   *
   * @param window 需要设置的窗口
   * @param dark  是否把状态栏字体及图标颜色设置为深色
   * @return boolean 成功执行返回true
   */
  public static boolean miuisetstatusbarlightmode(window window, boolean dark) {
    boolean result = false;
    if (window != null) {
      class clazz = window.getclass();
      try {
        int darkmodeflag = 0;
        class layoutparams = class.forname("android.view.miuiwindowmanager$layoutparams");
        field field = layoutparams.getfield("extra_flag_status_bar_dark_mode");
        darkmodeflag = field.getint(layoutparams);
        method extraflagfield = clazz.getmethod("setextraflags", int.class, int.class);
        if (dark) {
          extraflagfield.invoke(window, darkmodeflag, darkmodeflag);//状态栏透明且黑色字体
        } else {
          extraflagfield.invoke(window, 0, darkmodeflag);//清除黑色字体
        }
        result = true;
      } catch (exception e) {

      }
    }
    return result;
  }

}

activity中使用:

statusbarutil.setstatusbarlightmode(getwindow());

效果:

出现的问题:

1.statusbar背景色变成了colorprimarydark默认颜色,但是我的配置是白色背景(具体配置代码见最后).

分析原因:

setsystemuivisibility()会刷新view的属性配置.由于statusbar默认使用colorprimarydark属性.所以颜色会变回默认颜色

此时步骤一设置背景的方法就会失效.

  private void initstatusbar() {
    if (statusbarview == null) {
      int identifier = getresources().getidentifier("statusbarbackground", "id", "android");
      statusbarview = getwindow().findviewbyid(identifier);
    }
    if (statusbarview != null) {
      statusbarview.setbackgroundresource(mvpconfig.statusdrawable);
    }
  }

原因:当传入的resid相同时,就不会再次去设置背景色.

解决办法:

  private void initstatusbar() {
    if (statusbarview == null) {
      int identifier = getresources().getidentifier("statusbarbackground", "id", "android");
      statusbarview = getwindow().findviewbyid(identifier);
    }
    if (statusbarview != null) {
      statusbarview.setbackgrounddrawable(null);//在设置前将背景设置为null;
      statusbarview.setbackgroundresource(mvpconfig.statusdrawable);
    }
  }

修改后的效果:

三.完整代码:

1.mvpconfig

public class mvpconfig {
  public static int statusdrawable;
  public static int toolbarbackgroundcolor;
  public static int toolbarbackgrounddrawable;
  public static int backdrawable;
  public static boolean isstatusbarlight;

  public static void setstatusbardrawable(@drawableres int statusdraw) {
    statusdrawable = statusdraw;
  }

  public static boolean isstatusbar() {
    return statusdrawable > 0;
  }

  public static void settoolbardrawable(int toolbarbackgrounddrawable) {
    mvpconfig.toolbarbackgrounddrawable = toolbarbackgrounddrawable;
  }

  public static void setbackdrawable(int backdrawable) {
    mvpconfig.backdrawable = backdrawable;
  }

  public static void setisstatusbarlight(boolean isstatusbarlight) {
    if (build.version.sdk_int <= build.version_codes.lollipop_mr1) {
      mvpconfig.statusdrawable = color.parsecolor("#33ffffff");
    }
    mvpconfig.isstatusbarlight = isstatusbarlight;
  }

2.application中

 

@override
  public void oncreate() {
    super.oncreate();
    mvpconfig.settoolbardrawable(r.color.white);
    mvpconfig.setstatusbardrawable(r.color.white);
    mvpconfig.setbackdrawable(r.drawable.back);
    mvpconfig.setisstatusbarlight(true);
}

3.baseactivity

  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
 //延时加载数据.
    looper.myqueue().addidlehandler(new messagequeue.idlehandler() {
      @override
      public boolean queueidle() {
        if (isstatusbarlight()) {
          statusbarutil.setstatusbarlightmode(getwindow());
        }
        if (isstatusbar()) {
          initstatusbar();
          getwindow().getdecorview().addonlayoutchangelistener(new view.onlayoutchangelistener() {
            @override
            public void onlayoutchange(view v, int left, int top, int right, int bottom, int oldleft, int oldtop, int oldright, int oldbottom) {
              initstatusbar();
            }
          });
        }
        mpresenter.initdata();
        return false;
      }
    });
  }

 private void initstatusbar() {
    if (statusbarview == null) {
      int identifier = getresources().getidentifier("statusbarbackground", "id", "android");
      statusbarview = getwindow().findviewbyid(identifier);
    }
    if (statusbarview != null) {
      if (isstatusbarlight()) {
        statusbarview.setbackgrounddrawable(null);
      }
      statusbarview.setbackgroundresource(mvpconfig.statusdrawable);
    }
  }
  //子类通过复写该方法,控制是否改变statusbar
  protected boolean isstatusbar() {
    return mvpconfig.isstatusbar();
  }
//子类通过复写该方法,控制是否需要改变statusbar字体颜色
  protected boolean isstatusbarlight() {
    return mvpconfig.isstatusbarlight;
  }

四.补充:

6.0以下,5.0原生系统无法修改字体颜色,用了个比较取巧的办法,设置成半透明灰色.

 public static void setstatusbarlightmode(window window) {
    int type = getstatusbarlightmode(window);
    if (type == 1) {
      miuisetstatusbarlightmode(window, true);
    } else if (type == 2) {
      flymesetstatusbarlightmode(window, true);
    } else if (type == 3) {
      window.getdecorview().setsystemuivisibility(view.system_ui_flag_light_status_bar);
    } else {
      //5.0
      if (build.version.sdk_int <= build.version_codes.lollipop_mr1) {
        mvpconfig.statusdrawable = color.parsecolor("#33ffffff");
      }
    }
  }

由于是直接修改window中的statusbarview的背景,而frgament依赖于activity,所以在activity与fragment直接跳转时,状态栏不是很适用.比如:activity是蓝色,fragment需要是白色,fragment需要通过window修改状态栏颜色.有点麻烦.
