在开发过程中可能会有将状态栏设置成白底黑字的样式，但是Android系统只有在4.4之上才可以修改状态栏颜色，想要设置状态栏为黑字，只有在Android6.0以上系统或者小米的MIUI V6以上版本或者，魅族的Flyme4.0以上版本才可以设置。
Android6.0以上设置状态栏白底黑字
首先需要通过修改colors.xml文件中的colorPrimaryDark来将状态栏背景设为白色
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#fff</color>
<color name="colorAccent">#FF4081</color>
</resources>
然后在Activity中添加代码
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
this.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN|View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
}
}
小米的MIUI V6以上版本设置状态栏白底黑字
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;
}
魅族的Flyme4.0以上版本设置状态栏白底黑字
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;
}
