Android(安卓)沉浸式状态栏完美解决方案

2021-12-04
项目中经常需要状态栏沉浸式解决方案，网上很多解决方案的文章，现在总结一种实际项目中可行的方案：
1、前期准备
全局搜索你的代码里 是否有 android:fitsSystemWindow，如果有就删掉。
检查你的values、values-v19、values-v21等 是否配置了如下item标签：
// values-v19。v19 开始有 android:windowTranslucentStatus 这个属性
// values-v21。5.0 以上提供了 setStatusBarColor() 方法设置状态栏颜色。
凡是在style.xml中 有关 windowTranslucentNavigation、windowTranslucentStatus、statusBarColor 统统删掉，因为我们要通过代码去实现, xml中的各种属性全部不要写, 避免代码出现互相干扰, 会出现各种无效等的bug。
2、需要的工具类

}}这个类支持了设置状态栏透明, 设置状态栏颜色, 支持了状态栏深色浅色切换(则状态栏上的文字图标颜色) 3、使用
首先在Activity 的setContentView 下一行编写如下代码(一般你可以写到你的BaseActivity里,否则你每个activity都得写一次)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.xxx);
//注意调用setRootViewFitsSystemWindows里面 winContent.getChildCount()=0 导致代码无法继续
//是因为你需要在setContentView之后才可以调用 setRootViewFitsSystemWindows
//当FitsSystemWindows设置 true 时，会在屏幕最上方预留出状态栏高度的 padding
StatusBarUtil.setRootViewFitsSystemWindows(this,true);
//设置状态栏透明
StatusBarUtil.setTranslucentStatus(this);
//一般的手机的状态栏文字和图标都是白色的, 可如果你的应用也是纯白色的, 或导致状态栏文字看不清
//所以如果你是这种情况,请使用以下代码, 设置状态使用深色文字图标风格, 否则你可以选择性注释掉这个if内容
if (!StatusBarUtil.setStatusBarDarkTheme(this, true)) {
//如果不支持设置深色风格 为了兼容总不能让状态栏白白的看不清, 于是设置一个状态栏颜色为半透明,
//这样半透明+白=灰, 状态栏的文字能看得清
StatusBarUtil.setStatusBarColor(this,0x55000000);
}
}
由于界面风格很多, 比如同一个app有的界面是黑色风格的页面, 有的是白色风格的页面,有的是顶部是图片的界面希望沉浸进去, 同时此时状态栏文字要跟随改变。
比如4个不同的fragment,有一个是白色，一个是黑色, 另外两个是顶部是图片的
你还可以随时使用StatusBarUtil.setStatusBarColor(this,颜色值);设置不同fragment时 的状态栏颜色
前面设置了setRootViewFitsSystemWindows(this,true)带有 paddingTop=状态栏高度的效果，如果顶部不是图片布局 , 可以直接使用 setStatusBarColo设置相同颜色即可
如果顶部是图片布局, 想要图片沉浸, 必须设置fitsSystemWindows=false, 以去掉padding效果, 然后想办法 把图片上层的 其他View 整体 paddingTop=状态栏高 让其他View向下挪动。
当前带图片的activity重新设置setRootViewFitsSystemWindows(this,false);效果如下(你会发现图标跑左边了 )，去掉padding效果后图片沉浸了! 但内容进入了状态栏里被遮挡.
怎么以最方便的方式 让整个内容布局 往下挪动?
有很多教程都是写的是在代码里 findView，然后设置padding , 很是麻烦, 要是多个界面都这样代码岂止乱?在xml中使用状态栏高度值 ,结果发现这是几乎是不可能的, 因为编译后xml固定了值,除非使用反射, 但这到了安卓9.0不能反射系统api怎么办？
解决方案：自定义一个View ,用来做状态栏高度占位
/**
* 功能:状态栏高度View,用于沉浸占位
*/
public class StatusBarHeightView extends LinearLayout {
private int statusBarHeight;
private int type;
public StatusBarHeightView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
init(attrs);
}
public StatusBarHeightView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(attrs);
}
public StatusBarHeightView(Context context, @Nullable AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr);
init(attrs);
}
private void init(@Nullable AttributeSet attrs) {
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if(resourceId>0) {
statusBarHeight = getResources().getDimensionPixelSize(resourceId);
}
}else{
//低版本 直接设置0
statusBarHeight = 0;
}
if (attrs != null) {
TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.StatusBarHeightView);
type = typedArray.getInt(R.styleable.StatusBarHeightView_use_type, 0);
typedArray.recycle();
}
if (type == 1) {
setPadding(getPaddingLeft(), statusBarHeight, getPaddingRight(), getPaddingBottom());
}
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (type == 0) {
setMeasuredDimension(getDefaultSize(getSuggestedMinimumWidth(), widthMeasureSpec),
statusBarHeight);
} else {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
}
attrs.xml
解释下两个类型:
use_height: 设置当前布局高度=状态栏高度值 用于无子View时的占位
use_padding_top: 设置当前顶部padding=状态栏高度值 用于有子View时的占位
适配低于4.4时 占位View的高度为0 所以不可见
使用方法, 用StatusBarHeightView 来包住你要往下移动的内容! 单独留出要沉浸的View不包住,
举例:
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
android:layout_height="match_parent"
android:background="@mipmap/icon_top_bg"
android:scaleType="centerCrop" />
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_marginEnd="@dimen/widget_size_5"
app:use_type="use_padding_top"
android:orientation="vertical" >
android:layout_width="@dimen/title_height"
android:layout_height="@dimen/title_height"
android:padding="@dimen/widget_size_10"
android:src="@mipmap/icon_share_white" />
//不要忘记了, 在当前activity onCreate中设置 取消padding, 因为这个padding 我们用代码实现了,不需要系统帮我
StatusBarUtil.setRootViewFitsSystemWindows(this,false);
如果你按上面去做, 状态栏颜色无法被修改, 请检查上层布局是否设置了背景或者受了全局主题的
- @color/xxx
的颜色影响
