Android Button控件Inflate报错原因及解决方案

问题描述

在Schedule Activity中使用普通Button控件，点击按钮跳转至另一个Activity进行字段更新与API调用时，触发报错导致Activity无法启动。

相关代码

UpdateSchedule.class

public class UpdateSchedule extends AppCompatActivity {

    Button btnAddRoute, btnAddSource, btnRouteInfo, btnScheduleInfo;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_update_schedule);

        initViews();
    }
}

原因分析

从错误日志核心信息可定位问题：

系统尝试加载res/color/mtrl_btn_text_color_selector.xml资源时，出现文件缺失、损坏或内容格式错误
项目使用Material Components主题时，布局中的普通Button会被自动替换为MaterialButton，但对应的文本颜色选择器资源缺失，或资源中的颜色引用（如?attr/colorOnPrimary）在当前主题中未定义
资源编译缓存异常，导致正确的资源未被加载

解决方案

检查Material Components依赖：确保app模块的build.gradle中包含正确版本的Material Components依赖，同步后重新编译：

implementation 'com.google.android.material:material:1.9.0'

修复颜色选择器资源：若res/color/mtrl_btn_text_color_selector.xml缺失或损坏，可创建该文件并添加正确内容：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/your_pressed_color" android:state_enabled="true" android:state_pressed="true"/>
    <item android:color="@color/your_focused_color" android:state_enabled="true" android:state_focused="true"/>
    <item android:color="@color/your_enabled_color" android:state_enabled="true"/>
    <item android:color="@color/your_disabled_color"/>
</selector>

将上述颜色值替换为项目中已定义的具体颜色，或使用已在主题中声明的属性。

强制使用原生Button：若无需MaterialButton特性，可在布局中明确指定原生Button类：

<android.widget.Button
    android:id="@+id/add_route"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="80dp"
    android:text="Add Route" />

清理重建项目：执行Build -> Clean Project，再执行Build -> Rebuild Project，清除编译缓存并重新生成资源。
检查主题配置：确保AndroidManifest.xml中UpdateSchedule Activity的主题为Material Components兼容主题，例如：

<activity
    android:name=".activity.UpdateSchedule"
    android:theme="@style/Theme.MaterialComponents.Light.DarkActionBar"/>
