Menggunakan setelan teks sistem
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Di Android TV, setelan disediakan bagi pengguna untuk menentukan gaya teks mereka sendiri.
Panduan ini menunjukkan cara aplikasi bisa mendapatkan dan menerapkan API yang disediakan
gaya teksnya.
Opsi teks dapat ditemukan di Setelan > Sistem > Aksesibilitas > Teks:
Mendapatkan CaptioningManager
Dari suatu aktivitas, Anda bisa mendapatkan layanan teks dari Context-nya menggunakan
CaptioningManager:
CaptioningManager captioningManager = (CaptioningManager)context.getSystemService(Context.CAPTIONING_SERVICE);
Menangani perubahan gaya teks
Anda kemudian dapat menangani perubahan gaya teks dengan mengimplementasikan CaptioningChangeListener:
if (captioningManager != null) {
// Define a class to store the CaptionStyle details.
CurrentCaptionStyle currentCaptionStyle = new CurrentCaptionStyle;
// Define the listeners.
captioningManager.addCaptioningChangeListener(new CaptioningChangeListener() {
@Override
public void onEnabledChanged(boolean enabled) {
super.onEnabledChanged(enabled);
Log.d(TAG, "onEnabledChanged");
currentCaptionStyle.isEnabled = enabled;
}
@Override
public void onLocaleChanged(@Nullable Locale locale) {
super.onLocaleChanged(locale);
Log.d(TAG, "onLocaleChanged");
currentCaptionStyle.locale = locale;
}
@Override
public void onFontScaleChanged(float fontScale) {
super.onFontScaleChanged(fontScale);
Log.d(TAG, "onFontScaleChanged");
currentCaptionStyle.fontScale = fontScale;
}
@Override
public void onUserStyleChanged(@NonNull CaptionStyle userStyle) {
super.onUserStyleChanged(userStyle);
Log.d(TAG, "onUserStyleChanged");
currentCaptionStyle.hasBackgroundColor = userStyle.hasBackgroundColor();
currentCaptionStyle.backgroundColor = userStyle.backgroundColor;
currentCaptionStyle.backgroundOpcity = userStyle.backgroundColor >>> 24;
currentCaptionStyle.hasForegroundColor = userStyle.hasForegroundColor();
currentCaptionStyle.foregroundColor = userStyle.foregroundColor;
currentCaptionStyle.foregroundOpacity = userStyle.foregroundColor >>> 24;
currentCaptionStyle.hasWindowColor = userStyle.hasWindowColor();
currentCaptionStyle.windowColor = userStyle.windowColor;
currentCaptionStyle.windowOpcity = userStyle.windowColor >>> 24;
currentCaptionStyle.hasEdgeColor = userStyle.hasEdgeColor();
currentCaptionStyle.edgeColor = userStyle.edgeColor;
currentCaptionStyle.hasEdgeType = userStyle.hasEdgeType();
currentCaptionStyle.edgeType = userStyle.edgeType;
currentCaptionStyle.typeFace = userStyle.getTypeface();
}
});
Untuk mendapatkan CaptionStyle sistem, Anda dapat memanggil getUserStyle()
secara langsung:
CaptionStyle systemCaptionStyle = captioningManager.getUserStyle();
