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.
