关键字：状态栏着色 透明状态栏 沉浸式 白底黑字Github Demo：https://github.com/imflyn/Eyes 在谷歌官方的material设计文档中定义了新的状态栏设计。https://material.io/guidelines/layout/structure.html#structure-system-bars 默认情况下,状态栏的颜色是黑色的。同时状态栏颜色也可以半透明或是指定任意一种颜色。1.改变颜色后的状态栏 2.半透明状态栏 3.黑色状态栏 黑色icon或文字的状态栏 接下来讲一下具体实现 一.改变状态栏颜色4.4-5.0的处理：4.4-5.0还没有API可以直接修改状态栏颜色，所以必须先将状态栏设置为透明，然后在布局中添加一个背景为期望色值的View来作为状态栏的填充。 static void setStatusBarColor(Activity activity, int statusColor) { Window window = activity.getWindow(); //设置Window为全透明 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); ViewGroup mContentView = (ViewGroup) window.findViewById(Window.ID_ANDROID_CONTENT); //获取父布局 View mContentChild = mContentView.getChildAt(0); //获取状态栏高度 int statusBarHeight = getStatusBarHeight(activity); //如果已经存在假状态栏则移除，防止重复添加 removeFakeStatusBarViewIfExist(activity); //添加一个View来作为状态栏的填充 addFakeStatusBarView(activity, statusColor, statusBarHeight); //设置子控件到状态栏的间距 addMarginTopToContentChild(mContentChild, statusBarHeight); //不预留系统栏位置 if (mContentChild != null) { ViewCompat.setFitsSystemWindows(mContentChild, false); } //如果在Activity中使用了ActionBar则需要再将布局与状态栏的高度跳高一个ActionBar的高度，否则内容会被ActionBar遮挡 int action_bar_id = activity.getResources().getIdentifier("action_bar", "id", activity.getPackageName()); View view = activity.findViewById(action_bar_id); if (view != null) { TypedValue typedValue = new TypedValue(); if (activity.getTheme().resolveAttribute(R.attr.actionBarSize, typedValue, true)) { int actionBarHeight = TypedValue.complexToDimensionPixelSize(typedValue.data, activity.getResources().getDisplayMetrics()); setContentTopPadding(activity, actionBarHeight); } } }private static void removeFakeStatusBarViewIfExist(Activity activity) { Window window = activity.getWindow(); ViewGroup mDecorView = (ViewGroup) window.getDecorView(); View fakeView = mDecorView.findViewWithTag(TAG_FAKE_STATUS_BAR_VIEW); if (fakeView != null) { mDecorView.removeView(fakeView); } }private static View addFakeStatusBarView(Activity activity, int statusBarColor, int statusBarHeight) { Window window = activity.getWindow(); ViewGroup mDecorView = (ViewGroup) window.getDecorView(); View mStatusBarView = new View(activity); FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, statusBarHeight); layoutParams.gravity = Gravity.TOP; mStatusBarView.setLayoutParams(layoutParams); mStatusBarView.setBackgroundColor(statusBarColor); mStatusBarView.setTag(TAG_FAKE_STATUS_BAR_VIEW); mDecorView.addView(mStatusBarView); return mStatusBarView; }private static void addMarginTopToContentChild(View mContentChild, int statusBarHeight) { if (mContentChild == null) { return; } if (!TAG_MARGIN_ADDED.equals(mContentChild.getTag())) { FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mContentChild.getLayoutParams(); lp.topMargin += statusBarHeight; mContentChild.setLayoutParams(lp); mContentChild.setTag(TAG_MARGIN_ADDED); } }static void setContentTopPadding(Activity activity, int padding) { ViewGroup mContentView = (ViewGroup) activity.getWindow().findViewById(Window.ID_ANDROID_CONTENT); mContentView.setPadding(0, padding, 0, 0); }Android5.0以上的处理： static void setStatusBarColor(Activity activity, int statusColor) { Window window = activity.getWindow(); //取消状态栏透明 window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //添加Flag把状态栏设为可绘制模式 window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); //设置状态栏颜色 window.setStatusBarColor(statusColor); //设置系统状态栏处于可见状态 window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); //让view不根据系统窗口来调整自己的布局 ViewGroup mContentView = (ViewGroup) window.findViewById(Window.ID_ANDROID_CONTENT); View mChildView = mContentView.getChildAt(0); if (mChildView != null) { ViewCompat.setFitsSystemWindows(mChildView, false); ViewCompat.requestApplyInsets(mChildView); } }二.透明状态栏4.4-5.0的处理： static void translucentStatusBar(Activity activity) { Window window = activity.getWindow(); //设置Window为透明 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); ViewGroup mContentView = (ViewGroup) activity.findViewById(Window.ID_ANDROID_CONTENT); View mContentChild = mContentView.getChildAt(0); //移除已经存在假状态栏则,并且取消它的Margin间距 removeFakeStatusBarViewIfExist(activity); removeMarginTopOfContentChild(mContentChild, getStatusBarHeight(activity)); if (mContentChild != null) { //fitsSystemWindow 为 false, 不预留系统栏位置. ViewCompat.setFitsSystemWindows(mContentChild, false); } }5.0以上的处理： static void translucentStatusBar(Activity activity, boolean hideStatusBarBackground) { Window window = activity.getWindow(); //添加Flag把状态栏设为可绘制模式 window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); if (hideStatusBarBackground) { //如果为全透明模式，取消设置Window半透明的Flag window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //设置状态栏为透明 window.setStatusBarColor(Color.TRANSPARENT); //设置window的状态栏不可见 window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN); } else { //如果为半透明模式，添加设置Window半透明的Flag window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //设置系统状态栏处于可见状态 window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); } //view不根据系统窗口来调整自己的布局 ViewGroup mContentView = (ViewGroup) window.findViewById(Window.ID_ANDROID_CONTENT); View mChildView = mContentView.getChildAt(0); if (mChildView != null) { ViewCompat.setFitsSystemWindows(mChildView, false); ViewCompat.requestApplyInsets(mChildView); } }三.使用CollapsingToolbarLayout使ToolBar具有折叠效果类似图片中的效果 首先是XML布局： 4.4-5.0的处理： static void setStatusBarColorForCollapsingToolbar(Activity activity, final AppBarLayout appBarLayout, final CollapsingToolbarLayout collapsingToolbarLayout, Toolbar toolbar, int statusColor) { Window window = activity.getWindow(); //设置Window为全透明 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); ViewGroup mContentView = (ViewGroup) window.findViewById(Window.ID_ANDROID_CONTENT); //AppBarLayout,CollapsingToolbarLayout,ToolBar,ImageView的fitsSystemWindow统一改为false, 不预留系统栏位置. View mContentChild = mContentView.getChildAt(0); mContentChild.setFitsSystemWindows(false); ((View) appBarLayout.getParent()).setFitsSystemWindows(false); appBarLayout.setFitsSystemWindows(false); collapsingToolbarLayout.setFitsSystemWindows(false); collapsingToolbarLayout.getChildAt(0).setFitsSystemWindows(false); toolbar.setFitsSystemWindows(false); //为Toolbar添加一个状态栏的高度, 同时为Toolbar添加paddingTop,使Toolbar覆盖状态栏，ToolBar的title可以正常显示. if (toolbar.getTag() == null) { CollapsingToolbarLayout.LayoutParams lp = (CollapsingToolbarLayout.LayoutParams) toolbar.getLayoutParams(); int statusBarHeight = getStatusBarHeight(activity); lp.height += statusBarHeight; toolbar.setLayoutParams(lp); toolbar.setPadding(toolbar.getPaddingLeft(), toolbar.getPaddingTop() + statusBarHeight, toolbar.getPaddingRight(), toolbar.getPaddingBottom()); toolbar.setTag(true); } //移除已经存在假状态栏则,并且取消它的Margin间距 int statusBarHeight = getStatusBarHeight(activity); removeFakeStatusBarViewIfExist(activity); removeMarginTopOfContentChild(mContentChild, statusBarHeight); //添加一个View来作为状态栏的填充 final View statusView = addFakeStatusBarView(activity, statusColor, statusBarHeight); CoordinatorLayout.Behavior behavior = ((CoordinatorLayout.LayoutParams) appBarLayout.getLayoutParams()).getBehavior(); if (behavior != null && behavior instanceof AppBarLayout.Behavior) { int verticalOffset = ((AppBarLayout.Behavior) behavior).getTopAndBottomOffset(); if (Math.abs(verticalOffset) > appBarLayout.getHeight() - collapsingToolbarLayout.getScrimVisibleHeightTrigger()) { statusView.setAlpha(1f); } else { statusView.setAlpha(0f); } } else { statusView.setAlpha(0f); } appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() { @Override public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) { if (Math.abs(verticalOffset) > appBarLayout.getHeight() - collapsingToolbarLayout.getScrimVisibleHeightTrigger()) { //toolbar被折叠时显示状态栏 if (statusView.getAlpha() == 0) { statusView.animate().cancel(); statusView.animate().alpha(1f).setDuration(collapsingToolbarLayout.getScrimAnimationDuration()).start(); } } else { //toolbar展开时显示状态栏 if (statusView.getAlpha() == 1) { statusView.animate().cancel(); statusView.animate().alpha(0f).setDuration(collapsingToolbarLayout.getScrimAnimationDuration()).start(); } } } }); }5.0以上的处理： static void setStatusBarColorForCollapsingToolbar(final Activity activity, final AppBarLayout appBarLayout, final CollapsingToolbarLayout collapsingToolbarLayout, Toolbar toolbar, final int statusColor) { final Window window = activity.getWindow(); //取消设置Window半透明的Flag window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); ////添加Flag把状态栏设为可绘制模式 window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); //设置状态栏为透明 window.setStatusBarColor(Color.TRANSPARENT); //设置系统状态栏处于可见状态 window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); //通过OnApplyWindowInsetsListener()使Layout在绘制过程中将View向下偏移了,使collapsingToolbarLayout可以占据状态栏 ViewCompat.setOnApplyWindowInsetsListener(collapsingToolbarLayout, new OnApplyWindowInsetsListener() { @Override public WindowInsetsCompat onApplyWindowInsets(View v, WindowInsetsCompat insets) { return insets; } }); ViewGroup mContentView = (ViewGroup) window.findViewById(Window.ID_ANDROID_CONTENT); View mChildView = mContentView.getChildAt(0); //view不根据系统窗口来调整自己的布局 if (mChildView != null) { ViewCompat.setFitsSystemWindows(mChildView, false); ViewCompat.requestApplyInsets(mChildView); } ((View) appBarLayout.getParent()).setFitsSystemWindows(false); appBarLayout.setFitsSystemWindows(false); collapsingToolbarLayout.setFitsSystemWindows(false); collapsingToolbarLayout.getChildAt(0).setFitsSystemWindows(false); //设置状态栏的颜色 collapsingToolbarLayout.setStatusBarScrimColor(statusColor); toolbar.setFitsSystemWindows(false); //为Toolbar添加一个状态栏的高度, 同时为Toolbar添加paddingTop,使Toolbar覆盖状态栏，ToolBar的title可以正常显示. if (toolbar.getTag() == null) { CollapsingToolbarLayout.LayoutParams lp = (CollapsingToolbarLayout.LayoutParams) toolbar.getLayoutParams(); int statusBarHeight = getStatusBarHeight(activity); lp.height += statusBarHeight; toolbar.setLayoutParams(lp); toolbar.setPadding(toolbar.getPaddingLeft(), toolbar.getPaddingTop() + statusBarHeight, toolbar.getPaddingRight(), toolbar.getPaddingBottom()); toolbar.setTag(true); } appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() { private final static int EXPANDED = 0; private final static int COLLAPSED = 1; private int appBarLayoutState; @Override public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) { //toolbar被折叠时显示状态栏 if (Math.abs(verticalOffset) > collapsingToolbarLayout.getScrimVisibleHeightTrigger()) { if (appBarLayoutState != COLLAPSED) { appBarLayoutState = COLLAPSED;//修改状态标记为折叠 setStatusBarColor(activity, statusColor); } } else { //toolbar显示时同时显示状态栏 if (appBarLayoutState != EXPANDED) { appBarLayoutState = EXPANDED;//修改状态标记为展开 translucentStatusBar(activity, true); } } } }); }四.更改状态栏字体颜色在Android 6.0的Api中提供了SYSTEM_UI_FLAG_LIGHT_STATUS_BAR这么一个常量，可以使状态栏文字设置为黑色，但对6.0以下是不起作用的。小米和魅族的手机也可以达到这个效果，要做一些特殊的处理。可以参考小米和魅族的开发者文档。Flyme沉浸式状态栏MIUI 6 沉浸式状态栏调用方法MIUI 9「状态栏黑色字符」实现方法变更通知 public static void setStatusBarLightMode(Activity activity, int color) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //判断是否为小米或魅族手机，如果是则将状态栏文字改为黑色 if (MIUISetStatusBarLightMode(activity, true) || FlymeSetStatusBarLightMode(activity, true)) { //设置状态栏为指定颜色 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {//5.0 activity.getWindow().setStatusBarColor(color); } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {//4.4 //调用修改状态栏颜色的方法 setStatusBarColor(activity, color); } } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { //如果是6.0以上将状态栏文字改为黑色，并设置状态栏颜色 activity.getWindow().setBackgroundDrawableResource(android.R.color.transparent); activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR); activity.getWindow().setStatusBarColor(color); //fitsSystemWindow 为 false, 不预留系统栏位置. ViewGroup mContentView = (ViewGroup) activity.getWindow().findViewById(Window.ID_ANDROID_CONTENT); View mChildView = mContentView.getChildAt(0); if (mChildView != null) { ViewCompat.setFitsSystemWindows(mChildView, true); ViewCompat.requestApplyInsets(mChildView); } } } }小米MiUi修改状态栏方法 static boolean MIUISetStatusBarLightMode(Activity activity, boolean darkmode) { boolean result = false; 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); extraFlagField.invoke(activity.getWindow(), darkmode ? darkModeFlag : 0, darkModeFlag); result = true; } catch (Exception e) { e.printStackTrace(); } return result; }如果是MIUI9的系统还需要加上这段代码 Window window = getWindow();window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);Flyme修改状态栏方法 static boolean FlymeSetStatusBarLightMode(Activity activity, boolean darkmode) { boolean result = false; try { WindowManager.LayoutParams lp = activity.getWindow().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 (darkmode) { value |= bit; } else { value &= ~bit; } meizuFlags.setInt(lp, value); activity.getWindow().setAttributes(lp); result = true; } catch (Exception e) { e.printStackTrace(); } return result; }结语：更详细的参考Demo在github中，如果有错误也希望大家能够指出。 作者：imflyn链接：https://www.jianshu.com/p/932568ed31af |
