+
+**Goal:** 支持同时配置3个LLM模型，主页面同时显示3个结果框，发送时并行调用所有已配置的模型
+
+**Architecture:** 配置页面同时显示3组模型配置；主页结果显示区改为水平布局3个卡片；发送时并行调用所有模型
+
+**Tech Stack:** Kotlin, Android, OkHttp, Coroutine, SharedPreferences

+## 任务1: 修改 SecondActivity.kt 数据结构
+
+**Files:**
+- Modify: `flomo-ai/app/src/main/java/com/example/flomo_ai/SecondActivity.kt`
+
+- [ ] **Step 1: 修改 LLMConfig 类，添加 enabled 字段**
+
+在第650行 `data class LLMConfig` 中添加:
+```kotlin
+data class LLMConfig(
+    val name: String,
+    val baseUrl: String,
+    val apiKey: String,
+    val model: String,
+    val enabled: Boolean = true  // 新增：是否启用
+)
+```
+
+- [ ] **Step 2: 修改 SettingsData 类**
+
+在第663行 `data class SettingsData` 中，将 `llmConfigs` 类型改为固定3个元素的列表:
+```kotlin
+data class SettingsData(
+    val llmConfigs: List<LLMConfig>,
+    val selectedLlmIndex: Int?,
+    val headerConfigs: List<HeaderConfig>?,
+    val promptConfigs: List<PromptConfig>?,
+    val buttonConfigs: List<ButtonConfig>?,
+    val noteApiConfig: NoteApiConfig?,
+    val llmConfig: LLMConfig? = null
+)
+```
+
+- [ ] **Step 3: 提交**
+
+```bash
+git add flomo-ai/app/src/main/java/com/example/flomo_ai/SecondActivity.kt
+git commit -m "feat: add enabled field to LLMConfig"
+```
+
+---
+
+## 任务2: 修改 activity_second.xml 布局
+
+**Files:**
+- Modify: `flomo-ai/app/src/main/res/layout/activity_second.xml`
+
+- [ ] **Step 1: 将现有卡片内容包装为可复用的 LinearLayout**
+
+保留第一组配置，作为模板。新增2组相同的结构。
+
+每组配置需要唯一ID：
+- 第一组: etModelName1, etBaseUrl1, etApiKey1, btnToggleApiKey1, etModel1, btnTestConnection1, tvTestStatus1
+- 第二组: etModelName2, etBaseUrl2, etApiKey2, btnToggleApiKey2, etModel2, btnTestConnection2, tvTestStatus2
+- 第三组: etModelName3, etBaseUrl3, etApiKey3, btnToggleApiKey3, etModel3, btnTestConnection3, tvTestStatus3
+
+布局结构:
+```xml
+<!-- 第一组模型配置 -->
+<androidx.cardview.widget.CardView>
+    <LinearLayout>
+        <TextView android:text="模型1"/>
+        <!-- 配置名称、Base URL、API Key、Model、测试按钮 -->
+    </LinearLayout>
+</androidx.cardview.widget.CardView>
+
+<!-- 第二组模型配置 -->
+<androidx.cardview.widget.CardView>
+    <!-- 同上结构，ID带2 -->
+</androidx.cardview.widget.CardView>
+
+<!-- 第三组模型配置 -->
+<androidx.cardview.widget.CardView>
+    <!-- 同上结构，ID带3 -->
+</androidx.cardview.widget.CardView>
+```
+
+- [ ] **Step 2: 提交**
+
+```bash
+git add flomo-ai/app/src/main/res/layout/activity_second.xml
+git commit -m "feat: add 3 model config cards layout"
+```
+
+---
+
+## 任务3: 修改 SecondActivity.kt 逻辑
+
+**Files:**
+- Modify: `flomo-ai/app/src/main/java/com/example/flomo_ai/SecondActivity.kt:152-700`
+
+- [ ] **Step 1: 添加3组视图引用**
+
+在第46行后添加3组EditText和Button引用:
+```kotlin
+private lateinit var etBaseUrl1: EditText
+private lateinit var etApiKey1: EditText
+private lateinit var etModel1: EditText
+private lateinit var etModelName1: EditText
+private lateinit var btnTestConnection1: Button
+private lateinit var tvTestStatus1: TextView
+
+private lateinit var etBaseUrl2: EditText
+private lateinit var etApiKey2: EditText
+private lateinit var etModel2: EditText
+private lateinit var etModelName2: EditText
+private lateinit var btnTestConnection2: Button
+private lateinit var tvTestStatus2: TextView
+
+private lateinit var etBaseUrl3: EditText
+private lateinit var etApiKey3: EditText
+private lateinit var etModel3: EditText
+private lateinit var etModelName3: EditText
+private lateinit var btnTestConnection3: Button
+private lateinit var tvTestStatus3: TextView
+```
+
+- [ ] **Step 2: 修改 initViews() 方法，初始化所有视图**
+
+```kotlin
+etBaseUrl1 = findViewById(R.id.etBaseUrl1)
+// ... 其他第一组视图
+etBaseUrl2 = findViewById(R.id.etBaseUrl2)
+// ... 其他第二组视图
+etBaseUrl3 = findViewById(R.id.etBaseUrl3)
+// ... 其他第三组视图
+```
+
+- [ ] **Step 3: 修改 loadConfigurations() 方法，加载3个配置**
+
+从 SharedPreferences 加载3个配置，填充到对应视图。如果配置不足3个，补齐空配置。
+
+- [ ] **Step 4: 修改 saveConfigurations() 方法，保存3个配置**
+
+从3个视图组读取数据，保存为包含3个元素的列表。
+
+- [ ] **Step 5: 添加3个独立的测试方法**
+
+```kotlin
+private fun testConnection1() { testConnection(etBaseUrl1, etApiKey1, etModel1, tvTestStatus1, btnTestConnection1) }
+private fun testConnection2() { testConnection(etBaseUrl2, etApiKey2, etModel2, tvTestStatus2, btnTestConnection2) }
+private fun testConnection3() { testConnection(etBaseUrl3, etApiKey3, etModel3, tvTestStatus3, btnTestConnection3) }
+```
+
+- [ ] **Step 6: 设置3个测试按钮的点击事件**
+
+```kotlin
+btnTestConnection1.setOnClickListener { testConnection1() }
+btnTestConnection2.setOnClickListener { testConnection2() }
+btnTestConnection3.setOnClickListener { testConnection3() }
+```
+
+- [ ] **Step 7: 提交**
+
+```bash
+git add flomo-ai/app/src/main/java/com/example/flomo_ai/SecondActivity.kt
+git commit -m "feat: support 3 model configs with individual test"
+```
+

+
+## 任务4: 修改 activity_main.xml 布局
+
+**Files:**
+- Modify: `flomo-ai/app/src/main/res/layout/activity_main.xml`
+
+- [ ] **Step 1: 修改结果显示区为水平布局**
+
+将原来的单个结果卡片改为水平 ScrollView + LinearLayout，包含3个结果卡片。
+
+```xml
+<!-- 结果显示区标题 -->
+<TextView android:text="大模型返回结果"/>
+
+<!-- 水平滚动容器 -->
+<HorizontalScrollView
+    android:layout_width="match_parent"
+    android:layout_height="wrap_content">
+
+    <LinearLayout
+        android:layout_width="wrap_content"
+        android:layout_height="wrap_content"
+        android:orientation="horizontal">
+
+        <!-- 结果卡片1: 300dp宽 -->
+        <include layout="@layout/result_card" android:id="@+id/resultCard1"/>
+
+        <!-- 结果卡片2: 300dp宽 -->
+        <include layout="@layout/result_card" android:id="@+id/resultCard2"/>
+
+        <!-- 结果卡片3: 300dp宽 -->
+        <include layout="@layout/result_card" android:id="@+id/resultCard3"/>
+
+    </LinearLayout>
+</HorizontalScrollView>
+```
+
+- [ ] **Step 2: 创建 result_card.xml 布局**
+
+创建 `flomo-ai/app/src/main/res/layout/result_card.xml`:
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
+    android:layout_width="300dp"
+    android:layout_height="wrap_content"
+    android:orientation="vertical"

+    android:padding="16dp"
+    android:layout_marginEnd="12dp">
+
+    <TextView
+        android:id="@+id/tvModelName"
+        android:layout_width="match_parent"
+        android:layout_height="wrap_content"
+        android:textSize="14sp"
+        android:textColor="@color/text_secondary"

+        android:background="@color/primary"
+        android:layout_marginTop="8dp"
+        android:layout_marginBottom="8dp"/>
+
+    <TextView
+        android:id="@+id/outputStatusLabel"
+        android:layout_width="match_parent"
+        android:layout_height="wrap_content"
+        android:textSize="12sp"
+        android:textColor="@color/primary"/>
+
+    <EditText
+        android:id="@+id/outputTextView"
+        android:layout_width="match_parent"
+        android:layout_height="wrap_content"
+        android:minLines="3"
+        android:textSize="14sp"
+        android:editable="true"
+        android:gravity="top"
+        android:background="@android:drawable/edit_text"/>
+
+    <Button
+        android:id="@+id/btnCopyResult"
+        android:layout_width="match_parent"
+        android:layout_height="32dp"
+        android:layout_marginTop="8dp"
+        android:text="复制结果"/>
+</LinearLayout>
+```
+
+- [ ] **Step 3: 提交**
+
+```bash
+git add flomo-ai/app/src/main/res/layout/activity_main.xml flomo-ai/app/src/main/res/layout/result_card.xml
+git commit -m "feat: add horizontal result cards layout"

+## 任务5: 修改 MainActivity.kt 逻辑
+
+**Files:**
+- Modify: `flomo-ai/app/src/main/java/com/example/flomo_ai/MainActivity.kt`
+
+- [ ] **Step 1: 添加3组视图引用**
+

+outputTextView1 = findViewById(R.id.outputTextView1)
+outputTextView2 = findViewById(R.id.outputTextView2)
+outputTextView3 = findViewById(R.id.outputTextView3)
+// ... 其他视图
+```
+
+- [ ] **Step 3: 修改 sendButton.setOnClickListener，并行发送**
+
+```kotlin
+sendButton.setOnClickListener {
+    val inputText = inputEditText.text.toString()
+    if (inputText.isEmpty()) {
+        Toast.makeText(this, "请输入内容", Toast.LENGTH_SHORT).show()
