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: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.
