android 状态栏 statusbar
[TOC]
前言
由于公司项目的欢迎页是白色的，，修改状态栏颜色后，导致状态栏的白色字体完全被覆盖了，联想到之前在QQ、UC等一些app上都见到过状态栏的字体是深色的，想着，，必定有解决的方案。于是，有了本篇blog。
参考
下面是我在网上找到的两篇文章
1.白底黑字！Android浅色状态栏黑色字体模式
2.Android-->沉浸式状态栏字体颜色的修改(只针对小米和魅族)
解决方案
MIUI
public class MIUIHelper implements IHelper {
/**
* 设置状态栏字体图标为深色，需要MIUI6以上
*
* @param isFontColorDark 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
*/
@Override
public boolean setStatusBarLightMode(Activity activity, boolean isFontColorDark) {
Window window = activity.getWindow();
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 (isFontColorDark) {
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) {
e.printStackTrace();
}
}
return result;
}
}
flyme4+
public class FlymeHelper implements IHelper {
/**
* 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 isFontColorDark 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
*/
@Override
public boolean setStatusBarLightMode(Activity activity, boolean isFontColorDark) {
Window window = activity.getWindow();
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 (isFontColorDark) {
value |= bit;
} else {
value &= ~bit;
}
meizuFlags.setInt(lp, value);
window.setAttributes(lp);
result = true;
} catch (Exception e) {
e.printStackTrace();
}
}
return result;
}
}
android6.0+
1.代码设置
public class AndroidMHelper implements IHelper {
/**
* @return if version is lager than M
*/
@Override
public boolean setStatusBarLightMode(Activity activity, boolean isFontColorDark) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (isFontColorDark) {
// 沉浸式
// activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
//非沉浸式
activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
} else {
//非沉浸式
activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
}
return true;
}
return false;
}
}
2.style属性设置
<!--直接生效，状态栏文字颜色变成黑色，非沉浸式-->
<item name="android:windowLightStatusBar">true</item>
思路1
st=>start
condMIUI=>condition: set MIUI6 success?
condFlyme=>condition: set flyme4+ success?
cond6=>condition: set 6.0+ success?
e=>end
st->condMIUI
condMIUI(no)->condFlyme
condFlyme(no)->cond6
cond6(no)->e
cond6(yes)->e
condMIUI(yes)->e
condFlyme(yes)->e
思路2
st=>start
cond6=>condition: is 6.0+ ?
condFlyme=>condition: is flyme4+ ?
condMIUI=>condition: is MIUI6+ ?
e=>end
st->cond6
cond6(no)->condMIUI
condMIUI(no)->condFlyme
condFlyme(no)->6
cond6(yes)->e
condMIUI(yes)->e
condFlyme(yes)->e
思路实现
public class Helper {
@IntDef({
OTHER,
MIUI,
FLYME,
ANDROID_M
})
@Retention(RetentionPolicy.SOURCE)
public @interface SystemType {
}
public static final int OTHER = -1;
public static final int MIUI = 1;
public static final int FLYME = 2;
public static final int ANDROID_M = 3;
/**
* 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:MIUI 2:Flyme 3:android6.0
*/
public static int statusBarLightMode(Activity activity) {
@SystemType int result = 0;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if (new MIUIHelper().setStatusBarLightMode(activity, true)) {
result = MIUI;
} else if (new FlymeHelper().setStatusBarLightMode(activity, true)) {
result = FLYME;
} else if (new AndroidMHelper().setStatusBarLightMode(activity, true)) {
result = ANDROID_M;
}
}
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MIUI6、Flyme和6.0以上版本其他Android
*
* @param type 1:MIUI 2:Flyme 3:android6.0
*/
public static void statusBarLightMode(Activity activity, @SystemType int type) {
statusBarMode(activity, type, true);
}
/**
* 清除MIUI或flyme或6.0以上版本状态栏黑色字体
*/
public static void statusBarDarkMode(Activity activity, @SystemType int type) {
statusBarMode(activity, type, false);
}
private static void statusBarMode(Activity activity, @SystemType int type, boolean isFontColorDark) {
if (type == MIUI) {
new MIUIHelper().setStatusBarLightMode(activity, isFontColorDark);
} else if (type == FLYME) {
new FlymeHelper().setStatusBarLightMode(activity, isFontColorDark);
} else if (type == ANDROID_M) {
new AndroidMHelper().setStatusBarLightMode(activity, isFontColorDark);
}
}
}
结论
本方案适配一下系统
- android6.0+
- MIUI6
- flyme4+
据说：适配浅色状态栏深色字体的时候发现底层版本为Android6.0.1的MIUI7.1系统不支持View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR设置，还是得用MIUI自己的深色字体方法。所以，这里先适配MIUI跟flyme，再适配6.0，当然了，如果使用可以直接获取系统名，根据字符串判断，也可以先6.0在MIUI，但是这个不靠谱。还不如直接在6的系统上统一全配置上
说了这么多废话，，下面进入正题
