1、相关配置有先后顺序之分
class ToolBarBuilder {
private Toolbar toolbar;
/** 标题 */
private String title;
/** 是否要隐藏返回键 */
private boolean hideNavigationIcon = false;
/** 返回键图标 */
private int navigationIconId = R.drawable.icon_back;
/** NavigationIcon点击事件监听（返回键监听）*/
private View.OnClickListener navigationClickListener;
/** Menu响应事件监听 */
private Toolbar.OnMenuItemClickListener menuItemClickListener;
public ToolBarBuilder setToolbar(Toolbar toolbar){
this.toolbar = toolbar;
return this;
}
/** 标题 */
public ToolBarBuilder setTitle(String title){
this.title = title;
return this;
}
/** 返回键图标设置 */
public ToolBarBuilder setNavigationIconId(int navigationIconId){
this.navigationIconId = navigationIconId;
return this;
}
/** NavigationIcon点击事件监听（返回键监听）*/
public ToolBarBuilder setNavigationClickListener(View.OnClickListener menuItemClickListener){
this.navigationClickListener = navigationClickListener;
return this;
}
/** Menu Item 点击事件监听（返回键监听）*/
public ToolBarBuilder setMenuItemClickListener(Toolbar.OnMenuItemClickListener menuItemClickListener){
this.menuItemClickListener = menuItemClickListener;
return this;
}
/** 是否要隐藏返回键 */
public ToolBarBuilder setHideNavigationIcon(boolean hideNavigationIcon){
this.hideNavigationIcon = hideNavigationIcon;
return this;
}
public Toolbar build(){
if(toolbar != null){
if(!hideNavigationIcon){// 在不隐藏返回键的情况下要显示返回键
toolbar.setNavigationIcon(navigationIconId);
}
// 这个属性的配置要写在 setSupportActionBar（）之前才会有效果
toolbar.setTitle(title);
// 设置返回键监听事件
if(navigationClickListener == null){
navigationClickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
};
}
// 设置Toolbar为导航栏
setSupportActionBar(toolbar);
// 这个配置必须写在setSupportActionBar（）之后才会有效果。
toolbar.setNavigationOnClickListener(navigationClickListener);
// 这个配置必须写在setSupportActionBar（）之后才会有效果。
if(menuItemClickListener != null){
toolbar.setOnMenuItemClickListener(menuItemClickListener);
}
}
return toolbar;
}// end build
}// end ToolBarBuilder
2、样式设置
<style name="AppTheme" parent="AppTheme.Base">
</style>
<style name="AppTheme.Base" parent="Theme.AppCompat">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<!--配置toolbar的颜色，但是要在toolbar中进行设置才会起作用-->
<item name="colorPrimary">@color/bg_toolbar</item>
<!--配置系统栏的颜色-->
<item name="colorPrimaryDark">@color/bg_system_bar</item>
<!--配置整个窗口的背景颜色-->
<item name="android:windowBackground">@color/bg_window</item>
</style>
<style name="ToolbarTheme" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

<!-- Enable these below if you want clicking icons to trigger a ripple effect -->
<item name="selectableItemBackground">?android:selectableItemBackground</item>
<item name="selectableItemBackgroundBorderless">?android:selectableItemBackground</item>
</style>
<!-- This configures the styles for the title within the Toolbar -->
<style name="Toolbar.TitleText" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
