Android实现修改状态栏背景、字体和图标颜色的方法
作者:Jlanglang
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.
