一、沉浸式實(shí)現(xiàn)方式

實(shí)現(xiàn)沉浸式狀態(tài)樣主要有兩種方式，一種是通過(guò)設(shè)置theme來(lái)實(shí)現(xiàn)，另一種是代碼中實(shí)現(xiàn)

1.1通過(guò)設(shè)置theme來(lái)實(shí)現(xiàn)

通過(guò)theme設(shè)置也有兩種方法

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中通過(guò)函數(shù)API進(jìn)行區(qū)分

true

true

@android:color/transparent

1.2 代碼中設(shè)置

/**

* 通過(guò)設(shè)置全屏，設(shè)置狀態(tài)欄透明

*

* @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();

//兩個(gè) flag 要結(jié)合使用，表示讓?xiě)?yīng)用的主體內(nèi)容占用系統(tǒng)狀態(tài)欄的空間

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);

//設(shè)置狀態(tài)欄為透明，否則在部分手機(jī)上會(huì)呈現(xiàn)系統(tǒng)默認(rèn)的淺灰色

window.setStatusBarColor(Color.TRANSPARENT);

//導(dǎo)航欄顏色也可以考慮設(shè)置為透明色

//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);

}

}

}

上面設(shè)置完之后，會(huì)出現(xiàn)頁(yè)面擠到狀態(tài)欄中去了，如下圖，

image.png

針對(duì)這種情況又有2種解決辦法，一種是設(shè)置android:fitsSystemWindows，另一種獲取狀態(tài)樣高度后，設(shè)置頁(yè)面的paddingTop值。

方案一：

values/style.xml中設(shè)置

true

true

@android:color/transparent

true

方案二：

首先通過(guò)反射獲取狀態(tài)欄高度

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;

}

再獲取頁(yè)面的根布局設(shè)置paddingTop

final int statusHeight = StatusBarCompat.getStatusBarHeight(this);

root.mToolBar.setPadding(0, statusHeight, 0, 0);

修改后的效果：

二、狀態(tài)欄顏色修改

通過(guò)上面的設(shè)置可以實(shí)現(xiàn)狀態(tài)欄的沉浸效果，狀態(tài)欄顏色和字體顏色似乎不太近人意

android 5.0之后提供了修改狀態(tài)欄顏色的方法

window.setStatusColor(@ColorInt int color)

該方法的生效條件是給window添加LAG_DRAWS_SYSTEM_BAR_BACKGROUNDS并取消FLAG_TRANSLUCENT_STATUS屬性，android 4.4 需要用到SystemBarTintManager 輔助類(lèi)，在build.gradle中引用compile 'com.readystatesoftware.systembartint:systembartint:1.0.3'

修改的狀態(tài)欄顏色的代碼如下：

/**

* 修改狀態(tài)欄顏色，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庫(kù)使4.4版本狀態(tài)欄變色，需要先將狀態(tài)欄設(shè)置為透明

transparencyBar(activity);

SystemBarTintManager tintManager = new SystemBarTintManager(activity);

tintManager.setStatusBarTintEnabled(true);

tintManager.setStatusBarTintResource(colorId);

}

}

三、狀態(tài)欄文字顏色修改

android 6.0以上才添加修改狀態(tài)欄字體顏色，修改相對(duì)比較麻煩點(diǎn)，分為google原生、小米、魅族三種情況。

google原生狀態(tài)欄文字顏色修改

這個(gè)方法比較簡(jiǎn)單，通過(guò)切換DecorView兩個(gè)不同的標(biāo)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);

}

}

小米系統(tǒng)狀態(tài)欄文字顏色修改

直接來(lái)代碼

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);//狀態(tài)欄透明且黑色字體

} else {

extraFlagField.invoke(window, 0, darkModeFlag);//清除黑色字體

}

result = true;

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && RomUtils.isMiUIV7OrAbove()) {

//開(kāi)發(fā)版 7.7.13 及以后版本采用了系統(tǒng)API，舊方法無(wú)效但不會(huì)報(bào)錯(cuò)，所以?xún)蓚€(gè)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;

}

魅族系統(tǒng)狀態(tài)欄文字顏色修改

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;

}

修改成功之后的效果圖

四、使用建議

android 6.0之前，不能夠修改狀態(tài)欄文字顏色，默認(rèn)的文字顏色是白色，所以，在6.0以下要設(shè)置狀態(tài)欄顏色不能設(shè)置為白色，為了防止文字和背景顏色相同。

我的使用，6.0以上白色狀態(tài)欄，黑色背景；6.0以下黑色狀態(tài)欄，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以下默認(rèn)白色文字

StatusBarUtils.setStatusBarColor(this, R.color.black);//黑色背景

}

五、附加代碼

StatusBarUtils類(lèi)

/**

window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

window.setStatusBarColor(Color.TRANSPARENT);

window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE

| 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,

}

}
