我在使用应用程序主题更改背景颜色时遇到问题。
NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(this);
TypedValue typedValue = new TypedValue();
getTheme().resolveAttribute(R.attr.colorPrimary, typedValue, true);
int iPrimaryColor = typedValue.data;
getTheme().resolveAttribute(R.attr.colorPrimaryDark, typedValue, true);
int iPrimaryDarkColor = typedValue.data;
Intent notIntent = new Intent(getApplicationContext(), MainActivity.class);
notIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent notOpenOnClick = PendingIntent.getActivity(getApplicationContext(), 0, notIntent, PendingIntent.FLAG_UPDATE_CURRENT);
RemoteViews smallContentView = new RemoteViews(getPackageName(), R.layout.notification_small);
RemoteViews bigContentView = new RemoteViews(getPackageName(), R.layout.notification_expanded);
nBuilder.setSmallIcon(R.drawable.not_icon)
.setOngoing(true)
.setContentTitle(getCurrentSong().getTitle())
.setContentIntent(notOpenOnClick);
Notification not = nBuilder.build();
smallContentView.setInt(R.id.not_linLayout, "setBackgroundColor", iPrimaryColor);
smallContentView.setInt(R.id.not_imvDivider, "setBackgroundColor", iPrimaryDarkColor);
bigContentView.setInt(R.id.not_linLayout, "setBackgroundColor", iPrimaryColor);
bigContentView.setInt(R.id.not_imvDivider, "setBackgroundColor", iPrimaryDarkColor);
setListeners(smallContentView);
setListeners(bigContentView);
not.contentView = smallContentView;
not.bigContentView = bigContentView;
if (isPlaying()) {
not.contentView.setImageViewResource(R.id.not_btnPlayPause, R.drawable.ic_pause_48dp);
not.bigContentView.setImageViewResource(R.id.not_btnPlayPause, R.drawable.ic_pause_48dp);
}
else {
not.contentView.setImageViewResource(R.id.not_btnPlayPause, R.drawable.ic_play_48dp);
not.bigContentView.setImageViewResource(R.id.not_btnPlayPause, R.drawable.ic_play_48dp);
}
我已经尝试过了,但我的通知背景仍然是白色的。ID 是正确的,View linLayout 是一个 LinearLayout。
请记住:整个代码都是在服务中调用的!
谢谢!
