如何实现
首先只有Android版本大于等于4.4才能够实现这样的效果，并且在4.4和5.0的上可以有不同的方式实现，这里我就讲一讲我是如何实现的。
效果一：状态栏变色
大致的思路就是设置状态栏透明，然后为根ViewGroup添加一个与状态栏相同高度的View，设置其颜色。
/**
* Android4.4以上的状态栏着色
*
* @param window 一般都是用于Activity的window,也可以是其他的例如Dialog,DialogFragment
* @param statusBarColor 状态栏颜色
* @param alpha 透明栏透明度[0.0-1.0]
*/
public static void tintStatusBar(Window window, @ColorInt int statusBarColor, @FloatRange(from = 0.0, to = 1.0)
float alpha) {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
return;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.TRANSPARENT);
} else {
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
ViewGroup decorView = (ViewGroup) window.getDecorView();
ViewGroup contentView = (ViewGroup) window.getDecorView().findViewById(Window.ID_ANDROID_CONTENT);
View rootView = contentView.getChildAt(0);
if (rootView != null) {
//设置为true后，布局会自动加上状态栏高度的距离
ViewCompat.setFitsSystemWindows(rootView, true);
}
//设置一个状态栏
setStatusBar(decorView, statusBarColor, true);
//设置一个半透明效果，Material Design的效果
setTranslucentView(decorView, alpha);
}
/**
* 创建假的状态栏View
*/
private static void setStatusBar(ViewGroup container, @ColorInt int statusBarColor, boolean visible, boolean
addToFirst) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
View statusBarView = container.findViewById(R.id.statusbar_view);
if (statusBarView == null) {
statusBarView = new View(container.getContext());
statusBarView.setId(R.id.statusbar_view);
ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(container.getContext()));
if (addToFirst) {
container.addView(statusBarView, 0, lp);
} else {
container.addView(statusBarView, lp);
}
}
statusBarView.setBackgroundColor(statusBarColor);
statusBarView.setVisibility(visible ? View.VISIBLE : View.GONE);
}
}
效果二：全屏状态栏透明
/**
* Android4.4以上的沉浸式全屏模式
* <p>
* 注:
* 1.删除fitsSystemWindows属性:Android5.0以上使用该方法如果出现界面展示不正确,删除布局中所有fitsSystemWindows属性
* 或者调用forceFitsSystemWindows方法
* 2.不删除fitsSystemWindows属性:也可以区别处理,Android5.0以上使用自己的方式实现,不调用该方法
*

* @param alpha 透明栏透明度[0.0-1.0]
