透明状态栏的实现
这里需要适配android4.0和android5.0的效果。
效果图如下：
1.定义样式
在style.xml
<style name="AppThemeBase" parent="Theme.AppCompat.Light.NoActionBar"> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorAccent</item> <item name="android:divider">@drawable/ic_list_divider</item> <item name="android:dividerHeight">@dimen/division_line</item> <item name="android:listDivider">@drawable/ic_list_divider</item> <item name="android:homeAsUpIndicator">@drawable/ic_arrow_back_white_24dp</item></style><style name="AppTheme" parent="AppThemeBase">
在style-v19.xml<style name="AppTheme.Toolbar" parent="Widget.AppCompat.ActionBar"> <item name="android:layout_width">match_parent</item> <item name="android:layout_height">?attr/actionBarSize</item> <item name="android:background">?attr/colorPrimary</item> <item name="android:theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item></style>
<!-- Base application theme. --><style name="AppTheme" parent="AppThemeBase"></style><style name="AppTheme.TranslucentStatus"> <item name="android:windowTranslucentStatus">true</item></style>在style-v21.xml
<!-- Base application theme. --><style name="AppTheme" parent="AppThemeBase"></style><style name="AppTheme.TranslucentStatus"> <item name="android:windowTranslucentStatus">true</item> <item name="android:statusBarColor">@android:color/transparent</item></style><style name="AppTheme.Toolbar" parent="Widget.AppCompat.ActionBar"> <item name="android:layout_width">match_parent</item> <item name="android:layout_height">?attr/actionBarSize</item> <item name="android:background">?attr/colorPrimary</item> <item name="android:theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item> <item name="android:elevation">2dp</item></style>2.设置状态栏的工具类

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="supplier.ztxx.com.test.MainActivity"> <android.support.v7.widget.Toolbar style="@style/AppTheme.Toolbar" android:id="@+id/toolbar" app:title="标题栏"/> <com.scwang.smartrefresh.layout.SmartRefreshLayout android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/refreshLayout" > <android.support.v7.widget.RecyclerView android:id="@+id/recyclerView" android:layout_width="match_parent" android:layout_height="match_parent" android:overScrollMode="never" android:background="#fff" /> </com.scwang.smartrefresh.layout.SmartRefreshLayout> </LinearLayout>
5.在需要的activity中进行设置
StatusBarUtil.setPaddingSmart(this,findViewById(R.id.toolbar));//设置toolbar的样式StatusBarUtil.immersive(this, 0xff000000, 0.1f);//设置状态栏的参数
