从日志中可以看到，应用在启动时发生了崩溃，主要错误信息如下：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.activitytest/com.example.activitytest.MainActivity}: android.view.InflateException: Binary XML file line #11 in com.example.activitytest:layout/first_layout: Binary XML file line #11 in com.example.activitytest:layout/first_layout: Error inflating class com.example.activitytest.TitleLayout

这个错误表明在加载 first_layout 布局文件时，尝试实例化 com.example.activitytest.TitleLayout 类时发生了错误。具体原因可能有以下几种：

1. 自定义视图类 TitleLayout 的构造函数有问题：

   • 确保 TitleLayout 类有正确的构造函数。自定义视图类通常需要有以下两个构造函数之一：

     class TitleLayout @JvmOverloads constructor(
         context: Context, 
         attrs: AttributeSet? = null, 
         defStyleAttr: Int = 0
     ) : View(context, attrs, defStyleAttr) {
         // 你的代码
     }
     

2. 布局文件中的命名空间或属性有问题：

   • 确保 first_layout.xml 文件中使用的命名空间和属性是正确的。例如：

     <com.example.activitytest.TitleLayout
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         ... />
     

3. 资源文件或类路径有问题：

   • 确保 TitleLayout 类在 com.example.activitytest 包中，并且路径正确。
   • 确保所有相关资源文件（如布局文件、图片等）都存在且路径正确。

4. 其他可能的错误：

   • 检查 TitleLayout 类中的逻辑，确保没有其他可能导致崩溃的代码。
   • 检查 first_layout.xml 文件中是否有其他可能导致问题的视图或属性。

修复步骤

1. 检查 TitleLayout 类的构造函数： 确保 TitleLayout 类有正确的构造函数，例如：

   class TitleLayout @JvmOverloads constructor(
       context: Context, 
       attrs: AttributeSet? = null, 
       defStyleAttr: Int = 0
   ) : View(context, attrs, defStyleAttr) {
       // 你的代码
   }
   

2. 检查 first_layout.xml 文件： 确保布局文件中引用 TitleLayout 的方式是正确的，例如：

   <com.example.activitytest.TitleLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       ... />
   

3. 检查资源文件和类路径： 确保所有相关资源文件和类路径都是正确的。

4. 调试和日志：

   • 在 TitleLayout 类的构造函数中添加日志，查看是否有异常抛出。
   • 使用调试工具逐步检查代码，找出具体的错误原因。

通过以上步骤，应该可以找到并修复导致应用崩溃的问题。
