androidstyle沉浸式 安卓沉浸式

一、沉浸式实现方式

实现沉浸式状态样主要有两种方式，一种是通过设置theme来实现，另一种是代码中实现

1.1通过设置theme来实现

通过theme设置也有两种方法

方法一：
values/style.xml
values-v19/style.xml
true
true
values-v21/style.xml
false
true
@android:color/transparent
方法二：
直接在values/style.xml中通过函数API进行区分
true
true
@android:color/transparent
1.2 代码中设置
/**
* 通过设置全屏，设置状态栏透明
*
* @param activity
*/
private void fullScreen(Activity activity) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = activity.getWindow();
View decorView = window.getDecorView();
//两个 flag 要结合使用，表示让应用的主体内容占用系统状态栏的空间
int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
decorView.setSystemUiVisibility(option);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
//设置状态栏为透明，否则在部分手机上会呈现系统默认的浅灰色
window.setStatusBarColor(Color.TRANSPARENT);
//导航栏颜色也可以考虑设置为透明色
//window.setNavigationBarColor(Color.TRANSPARENT);
} else {
Window window = activity.getWindow();
WindowManager.LayoutParams attributes = window.getAttributes();
int flagTranslucentStatus = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
int flagTranslucentNavigation = WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION;
attributes.flags |= flagTranslucentStatus;
// attributes.flags |= flagTranslucentNavigation;
window.setAttributes(attributes);
}
}
}
上面设置完之后，会出现页面挤到状态栏中去了，如下图，
image.png
针对这种情况又有2种解决办法，一种是设置android:fitsSystemWindows，另一种获取状态样高度后，设置页面的paddingTop值。
方案一：
values/style.xml中设置
true
true
@android:color/transparent
true
方案二：
首先通过反射获取状态栏高度
StatusBarCompat.class
public static int getStatusBarHeight(Context context) {
int result = 0;
int resId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resId > 0) {
result = context.getResources().getDimensionPixelOffset(resId);
}
return result;
}
再获取页面的根布局设置paddingTop
final int statusHeight = StatusBarCompat.getStatusBarHeight(this);
root.mToolBar.setPadding(0, statusHeight, 0, 0);
修改后的效果：

二、状态栏颜色修改
通过上面的设置可以实现状态栏的沉浸效果，状态栏颜色和字体颜色似乎不太近人意
android 5.0之后提供了修改状态栏颜色的方法
window.setStatusColor(@ColorInt int color)
该方法的生效条件是给window添加LAG_DRAWS_SYSTEM_BAR_BACKGROUNDS并取消FLAG_TRANSLUCENT_STATUS属性，android 4.4 需要用到SystemBarTintManager 辅助类，在build.gradle中引用compile 'com.readystatesoftware.systembartint:systembartint:1.0.3'
修改的状态栏颜色的代码如下：
/**
* 修改状态栏颜色，支持4.4以上版本
* @param activity
* @param colorId
*/
public static void setStatusBarColor(Activity activity, int colorId) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = activity.getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(activity.getResources().getColor(colorId));
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
//使用SystemBarTint库使4.4版本状态栏变色，需要先将状态栏设置为透明
transparencyBar(activity);
SystemBarTintManager tintManager = new SystemBarTintManager(activity);
tintManager.setStatusBarTintEnabled(true);
tintManager.setStatusBarTintResource(colorId);
}
}
三、状态栏文字颜色修改
android 6.0以上才添加修改状态栏字体颜色，修改相对比较麻烦点，分为google原生、小米、魅族三种情况。
google原生状态栏文字颜色修改
这个方法比较简单，通过切换DecorView两个不同的标志位
private static void setAndroidNativeLightStatusBar(Activity activity, boolean dark) {
View decor = activity.getWindow().getDecorView();
if (dark) {
decor.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
} else {
decor.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
}
}
小米系统状态栏文字颜色修改
直接来代码
public static boolean MIUISetStatusBarLightMode(Activity activity, boolean dark) {
boolean result = false;
Window window = activity.getWindow();
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;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && RomUtils.isMiUIV7OrAbove()) {
//开发版 7.7.13 及以后版本采用了系统API，旧方法无效但不会报错，所以两个方式都要加上
if (dark) {
activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
} else {
activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
}
}
} catch (Exception e) {
}
}
return result;
}
魅族系统状态栏文字颜色修改
private static boolean setFlymeLightStatusBar(Activity activity, boolean dark) {
boolean result = false;
if (activity != null) {
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 (dark) {
value |= bit;
} else {
value &= ~bit;
}
meizuFlags.setInt(lp, value);
activity.getWindow().setAttributes(lp);
result = true;
} catch (Exception e) {
}
}
return result;
}

四、使用建议
android 6.0之前，不能够修改状态栏文字颜色，默认的文字颜色是白色，所以，在6.0以下要设置状态栏颜色不能设置为白色，为了防止文字和背景颜色相同。
我的使用，6.0以上白色状态栏，黑色背景；6.0以下黑色状态栏，白色背景
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
StatusBarUtils.setLightStatusBar(this, true);//黑色文字
StatusBarUtils.setStatusBarColor(this, R.color.white);//白色背景
}else {
//6.0以下默认白色文字
StatusBarUtils.setStatusBarColor(this, R.color.black);//黑色背景
}
五、附加代码

/**

| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window window = activity.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
}
