Android中如何修改GitHub Square Calendar的月份文本颜色

Got it, let's tackle this problem together—since the provided color configs don't include a direct option for the month title, we need a couple of workarounds to get that white text you want. Here are three reliable methods you can try:

Method 1: Modify the Month Title via Code (Most Direct) #

The CalendarPickerView’s month title is a hidden TextView inside the custom view. You can locate it programmatically and update its color after initializing the calendar.

Option A: Recursive View Traversal #

If you don’t know the exact ID of the month title TextView, you can traverse the calendar’s child views to find it (month titles follow the "Month Year" format, so we can use that as a clue):

CalendarPickerView calendar = findViewById(R.id.calendar);
// First, initialize your calendar (set date ranges, selected dates, etc.)

// Locate the month title TextView
TextView monthTitle = findMonthTitle(calendar);
if (monthTitle != null) {
    monthTitle.setTextColor(getResources().getColor(R.color.white));
}

// Helper method to find the month title TextView
private TextView findMonthTitle(ViewGroup parent) {
    for (int i = 0; i < parent.getChildCount(); i++) {
        View child = parent.getChildAt(i);
        if (child instanceof TextView) {
            TextView tv = (TextView) child;
            // Month titles have a space (e.g., "October 2024")
            if (tv.getText().toString().contains(" ")) {
                return tv;
            }
        } else if (child instanceof ViewGroup) {
            TextView result = findMonthTitle((ViewGroup) child);
            if (result != null) {
                return result;
            }
        }
    }
    return null;
}

Option B: Use the Exact View ID #

Looking into the TimesSquare library source code, the month title TextView has the ID month_title. You can directly reference it using getResources().getIdentifier() (since the library’s R class isn’t publicly accessible):

CalendarPickerView calendar = findViewById(R.id.calendar);
// Initialize calendar first

int monthTitleId = getResources().getIdentifier("month_title", "id", getPackageName());
TextView monthTitle = calendar.findViewById(monthTitleId);
if (monthTitle != null) {
    monthTitle.setTextColor(Color.WHITE);
}

Method 2: Override Text Style via Theme #

If the month title uses a system text appearance (like TextAppearance.Large), you can override this style in your app’s theme to set white text. Note that this might affect other views using the same text style, so test carefully.

Add this to your styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Your existing theme attributes -->
    <item name="android:textAppearanceLarge">@style/CustomMonthTitleStyle</item>
</style>

<style name="CustomMonthTitleStyle" parent="android:TextAppearance.Large">
    <item name="android:textColor">@color/white</item>
</style>

Method 3: Modify the Library Source Code (For Full Control) #

If the above methods don’t work, you can fork the TimesSquare library and adjust the month title color directly:

1. Download the library source code from its GitHub repo.
2. Navigate to library/src/main/res/layout/month_header.xml.
3. Update the android:textColor attribute of the TextView to @color/white.
4. Import the modified library as a local module in your Android project instead of using the remote dependency.
