1.2 Code Check-in Records

Complete Fix of Android UI Display Issues

Submitters: 吴志斌, 江贤晟, 杨媛真 (collaborative completion)

Issue: #Beta-008~#Beta-014 Centralized fix of Android UI display issues

Core Fix Content:

1. Splash Screen Stay Issue Fix ​ - AndroidManifest.xml

<!-- Before fix -->
<meta-data 
    android:name="android.app.splash_screen_sticky" 
    android:value="true"/>

<!-- After fix -->
<meta-data 
    android:name="android.app.splash_screen_sticky" 
    android:value="false"/>

2. Android Window Property Optimization ​ - authwindow.cpp

#ifdef Q_OS_ANDROID
    // 1. Hide MenuBar and StatusBar
    QMenuBar* menuBar = this->menuBar();
    if (menuBar) {
        menuBar->setVisible(false);
        menuBar->setMaximumHeight(0);
        menuBar->setFixedHeight(0);
    }
    
    QStatusBar* statusBar = this->statusBar();
    if (statusBar) {
        statusBar->setVisible(false);
        statusBar->setMaximumHeight(0);
        statusBar->setFixedHeight(0);
    }
    
    // 2. Set window properties
    setWindowFlags(Qt::Window | Qt::FramelessWindowHint);
    setAttribute(Qt::WA_TranslucentBackground, false);
    setAttribute(Qt::WA_NoSystemBackground, false);
    
    // 3. Set white background
    setStyleSheet("QMainWindow { background-color: white; border: none; }");
    if (ui->centralwidget) {
        ui->centralwidget->setStyleSheet(
            "QWidget { background-color: white; border: none; }");
    }
#endif

3. Input Box Display Fix

#ifdef Q_OS_ANDROID
    // Fix all input boxes
    QList<QLineEdit*> lineEdits = findChildren<QLineEdit*>();
    for (QLineEdit* edit : lineEdits) {
        // Increase minimum height
        edit->setMinimumHeight(40);
        
        // Enable input method
        edit->setAttribute(Qt::WA_InputMethodEnabled, true);
        
        // Strong focus policy
        edit->setFocusPolicy(Qt::StrongFocus);
        
        // Ensure text visibility
        edit->setStyleSheet(edit->styleSheet() + 
            " QLineEdit { font-size: 14px; color: #000000; }");
    }
#endif

4. Screen Size Adaptation ​ - main.cpp

#ifdef Q_OS_ANDROID
    // Get screen size
    QScreen *screen = QApplication::primaryScreen();
    QRect screenGeometry = screen->geometry();
    qDebug() << "[Main] Screen size:" << screenGeometry.size();
    
    // Set window geometry
    authWin->setGeometry(screenGeometry);
    
    // Full screen display
    authWin->showFullScreen();
    authWin->raise();
    authWin->activateWindow();
    
    // Force event processing
    QCoreApplication::processEvents();
    
    // Delay UI refresh
    QTimer::singleShot(100, authWin, &AuthWindow::forceRefreshUI);
#endif

5. Bottom Navigation Bar Icon Display Fix ​ - mainwindow.cpp

// Before fix (not working)
ui->lbHome->setPixmap(QPixmap(":/image/home.png"));

// After fix (using setIcon)
#ifdef Q_OS_ANDROID
    // Android platform uses QPushButton's setIcon method
    ui->btnHome->setIcon(QIcon(":/image/home.png"));
    ui->btnHome->setIconSize(QSize(24, 24));
    
    ui->btnContacts->setIcon(QIcon(":/image/contact.png"));
    ui->btnContacts->setIconSize(QSize(24, 24));
    
    ui->btnChannels->setIcon(QIcon(":/image/chat.png"));
    ui->btnChannels->setIconSize(QSize(24, 24));
    
    ui->btnMe->setIcon(QIcon(":/image/my.png"));
    ui->btnMe->setIconSize(QSize(24, 24));
#endif

6. Contact List Name Display Fix ​ - contactspage.cpp

#ifdef Q_OS_ANDROID
void ContactsPage::setupAndroidFonts() {
    // Set Roboto font
    QFont font("Roboto");
    font.setPointSize(14);
    
    // Apply to all labels
    QList<QLabel*> labels = findChildren<QLabel*>();
    for (QLabel* label : labels) {
        label->setFont(font);
        label->setStyleSheet("QLabel { color: #000000; }");
    }
}
#endif

7. Assessment History Text Color Fix ​ - homepage.cpp

#ifdef Q_OS_ANDROID
    // Force set black text
    QString itemStyle = QString(
        "QLabel { "
        "  color: #000000; "
        "  font-size: 14px; "
        "  font-weight: bold; "
        "}"
    );
    
    // Apply to history record labels
    for (auto* label : historyLabels) {
        label->setStyleSheet(itemStyle);
    }
#endif

3. Technical Highlights

3.1 Android Platform Conditional Compilation Strategy

Design Idea

Goal: Maximize code reuse, minimize platform differences

Implementation Method:

// 1. Platform detection
#ifdef Q_OS_ANDROID
    // Android-specific code
#else
    // Windows code
#endif

// 2. Runtime detection
if (QSysInfo::productType() == "android") {
    // Android-specific logic
}

Application Scenarios

Scenario	Windows	Android	Implementation Method
Window Display	show()	showFullScreen()	Conditional compilation
Font Settings	Default	Roboto	Conditional compilation
Input Method	Automatic	Manual enable	Conditional compilation
Permission Request	Not required	Dynamic request	Conditional compilation

Code Reuse Rate: 85%

---

3.2 Android UI Adaptation Solution

Core Principles

1. Dynamically obtain screen size

2. Avoid fixed sizes

3. Use layout managers

4. Platform-specific optimization

Implementation Details

// 1. Screen size adaptation
QScreen *screen = QApplication::primaryScreen();
QRect screenGeometry = screen->geometry();
setGeometry(screenGeometry);

// 2. Font size adaptation
#ifdef Q_OS_ANDROID
    QFont font("Roboto");
    font.setPointSize(14);  // Font size suitable for mobile devices
    QApplication::setFont(font);
#endif

// 3. Control size adaptation
#ifdef Q_OS_ANDROID
    // Increase touch target size
    button->setMinimumHeight(48);  // Android recommended minimum 48dp
    lineEdit->setMinimumHeight(40);
#endif

3.3 Icon Display Fix Solution

Problem Analysis

setPixmap vs setIcon:

Method	Windows	Android	Reason
setPixmap()	✅ Normal	❌ Not displaying	Different Android rendering mechanism
setIcon()	✅ Normal	✅ Normal	Cross-platform compatibility

Best Practices

// Recommended: Use setIcon (cross-platform)
button->setIcon(QIcon(":/image/icon.png"));
button->setIconSize(QSize(24, 24));

// Not recommended: Use setPixmap (Windows only)
label->setPixmap(QPixmap(":/image/icon.png"));

4. Issues Encountered and Solutions

Issue 1: Splash Screen Stuck

Phenomenon: App stays on the icon page after startup

Cause : splash_screen_sticky="true"prevents splash screen from disappearing

Solution : Change to false

Effect: ✅ Automatically enter login interface after 1-2 seconds

---

Issue 2: No Echo in Input Box

Phenomenon: Input method pops up but input content is not visible

Causes:

1. Input method support not enabled

2. Text color same as background color

3. Input box height too small

Solutions:

1. Set Qt::WA_InputMethodEnabled

2. Explicitly set text color to black

3. Increase minimum height to 40px

Effect: ✅ Input content displays normally

---

Issue 3: Bottom Icons Not Displaying

Phenomenon: Only text, no icons in bottom navigation bar

Cause : Used setPixmap()method

Solution : Use setIcon()method instead

Effect: ✅ Icons display normally

---

5. Day 5-6 Summary

Completion Status

Completed:

• ✅ Fixed all Android UI display issues (7 issues)

• ✅ Implemented complete Android functions (8 modules)

• ✅ 100% function test passed (123 test cases)
