Android系统都有深色状态栏字体模式,但是目前只看到了小米和魅族公开了各自的实现方法,小米的支持MIUI V6以上版本,魅族的支持Flyme4.0以上版本。Android6.0以上系统好多品牌手机都好多都可以修改:/*** 设置状态栏图标为深色和魅族特定的文字风格,Flyme4.0以上* 可以用来判断是否为Flyme用户* @param window 需要设置的窗口* @param dark

官方在Android6.0中提供了亮色状态栏模式,配置只需一行代码:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
activity.getWindow().getDecorView().setSystemUiVisibility( View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN|View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
}
在设置状态栏全透明后,整个activity布局都会上移充满整个屏幕,如果你不想让布局上移的话就需要在根布局设置:
android:fitsSystemWindows="true"
以下是工具类:
public class StatusBarUtil {
/**
* 修改状态栏为全透明
* @param activity
*/

public static void transparencyBar(Activity activity){
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.TRANSPARENT);
} 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);
}
