|
||
|
||
**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">
|
||
|

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"?>

## 任务5: 修改 MainActivity.kt 逻辑
|
||
|
||
**Files:**
|
||
- Modify: `flomo-ai/app/src/main/java/com/example/flomo_ai/MainActivity.kt`

```
|
||
|

- [ ] **Step 2: 在 onCreate() 中初始化视图**
|
||
|
||
```kotlin
|
||
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()

- [ ] **Step 5: 添加3个复制按钮的点击事件**
|
||
|
||
```kotlin
|
||
btnCopyResult1.setOnClickListener { copyToClipboard(outputTextView1.text.toString()) }
|
||
btnCopyResult2.setOnClickListener { copyToClipboard(outputTextView2.text.toString()) }
