自定义标题栏

现在很多人用toolbar 来代替 标题栏， 不过还是有些公司设计的还是左中右那种标题，

初入android 

还是很多人对toolbar的使用不是很好。

自己封装了一个 标题栏

可以 带 返回 标题 右侧按钮的

 方便灵活

自学的android 不是很好。

代码附上

布局文件：include_head
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="@style/title_style" >

<include layout="@layout/include_back_button_layout" />

<TextView
android:id="@+id/include_head_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="标题"
android:textColor="@color/white"
android:textSize="20sp" />

<ImageView
android:id="@+id/include_head_logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:padding="10dp"
android:text="右侧按钮"
android:textColor="@color/darkgrey"
android:textSize="16sp"

<Button
android:id="@+id/include_right_brn"

android:layout_centerVertical="true"
android:gravity="center"
android:padding="10dp"
android:text="右侧按钮"
android:visibility="gone" />

</RelativeLayout>

需要个返回按钮，也是自己瞎封装了一个 ，用着方便
include_back_button_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >

<Button
android:id="@+id/back_btn"
style="@style/back_btn_style"
android:drawableStart="@drawable/back" />

</LinearLayout>

使用方法
appTitle.init(AppTitleStyle.BACK_TITLE_RIGHT);
appTitle.setTitleRightText("发表", "发表");
appTitle.setbackClisener(this);
appTitle.setRightClisener(this);
