安卓沉浸式状态栏

安卓沉浸式状态栏
实现Activity嵌套fragment，不同fragment顶部实现不同的效果(图片沉浸状态栏，设置不同颜色的状态栏)
效果图
- 首先在Activity的onCreate(Bundle savedInstanceState)方法中setContentView(R.layout.xxx)下面设置动态显示隐藏状态栏
if (Build.VERSION. SDK_INT >= 21) {
View decorView = getWindow().getDecorView();
int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
decorView.setSystemUiVisibility(option);
getWindow().setStatusBarColor(Color.TRANSPARENT);//状态栏透明
}
/* setSystemUiVisibility(int visibility) 动态显示隐藏状态栏
* View.SYSTEM_UI_FLAG_FULLSCREEN 全屏显示并隐藏状态栏
* View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 全屏显示布局不占用状态栏空间，状态栏正常显示，activity顶部布局被状态栏遮住
* */
2.上面设置会导致顶部布局被状态栏遮挡住，所以我们需要写一个View，高度等于状态栏的高度,将布局标题显示出来
在具体xml中加入下面代码
<!--android:background="@color/colorAccent"根据具体自己需要的标题栏颜色去进行设置，
若顶部是图片则不需要加背景-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="@+id/ll_title"
android:background="@color/colorAccent"
>
<View
android:id="@+id/status_bar"
android:layout_width="match_parent"
android:layout_height="0dp"
/>
</LinearLayout>
并通过java代码获取状态栏高度
View view = inflater.inflate(R.layout.fragment_first, container, false);
View mStateBar = view.findViewById( R.id.status_bar);
mStateBar.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,StatusBarUtil.getStatusBarHeight(getActivity())));//填充状态栏
/*StatusBarUtil.getStatusBarHeight(getActivity())获取状态栏高度*/

//获取状态栏高度

if (resourceId > 0) {
result = context.getResources().getDimensionPixelSize(resourceId);
}
return result;
}
}
状态栏默认字体是白色,我们可以在Activiy当中点击切换不同fragment中设置白色 黑色字体切换
switch (getmDefaultShow) {
case first:
StatusBarUtil.setStatusBarDarkTheme(this, false);
break;
case second:
StatusBarUtil.setStatusBarDarkTheme(this, false);
break;
case third:
StatusBarUtil.setStatusBarDarkTheme(this, false);
break;
case forth:
//黑色字体
StatusBarUtil.setStatusBarDarkTheme(this, true);
break;
}
