Android实现修改状态栏背景 字体 图标颜色

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:实现状态栏(statusbar)渐变效果其实很简单

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):

很明显的半透明黑色背景.

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;
    }

    /**

     */
    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;
    }

}
复制代码

activity中使用:

 StatusBarUtil.setStatusBarLightMode(getWindow());
复制代码

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);
        }
    }
复制代码

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(0); //这样也可以 
          statusBarView.setBackgroundResource(MVPConfig.statusDrawable);
        }
    }
复制代码

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;
    }


复制代码

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);
}
复制代码

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;
    }

复制代码

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");
            }
        }
    }

复制代码
  • 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.
