## 4.7 添加音乐、贴纸和气泡文字
|
|
|
|
添加音乐时要先通过MusicSet类进行音乐设置。
|
|
|
|
```
|
|
|
|
MusicSet musicSet = null;
|
|
|
|
if (isAddMusic) {
|
|
|
|
musicSet = new MusicSet();
|
|
|
|
int startMusicPos = startCutMusicPosition / 1000;
|
|
|
|
//设置音乐路径
|
|
|
|
musicSet.setMusicPath(bacMusicPath);
|
|
|
|
//设置音乐开始的位置，单位：秒
|
|
|
|
musicSet.setStartMusicPos(startMusicPos);
|
|
|
|
//原声大小 0.0~1.0f
|
|
|
|
musicSet.setOriginVolume(originVolume);
|
|
|
|
//音乐大小 0.0~1.0f
|
|
|
|
musicSet.setMusicVolume(musicVolume);
|
|
|
|
}
|
|
|
|
|
|
|
|
```
|
|
|
|
添加贴纸和气泡文字时，通过StickerSet进行贴纸和气泡文字设置。
|
|
|
|
```
|
|
|
|
List<StickerSet> stickerSets = new ArrayList<>();
|
|
|
|
StickerSet stickerSet = new StickerSet();
|
|
|
|
//设置贴纸和气泡文字开始显示的时间，单位：秒
|
|
|
|
stickerSet.setStartShowTime(sticker.getStartShowTime());
|
|
|
|
//设置贴纸和气泡文字结束显示的时间，单位：秒
|
|
|
|
stickerSet.setEndShowTime(sticker.getEndShowTime());
|
|
|
|
//设置X轴偏移位置
|
|
|
|
stickerSet.setxOffSet(xOffSet);
|
|
|
|
//设置y轴偏移位置
|
|
|
|
stickerSet.setyOffSet(yOffSet);
|
|
|
|
//设置贴纸和气泡文字路径
|
|
|
|
stickerSet.setStickerPath(stickerPath);
|
|
|
|
stickerSets.add(stickerSet);
|
|
|
|
```
|
|
|
|
只添加音乐时，传入参数musicSet，stickerSets传入参数null。只添加贴纸和气泡文字时，传入参数stickerSets，musicSet传入参数null。同时添加音乐、贴纸和气泡文字时，传入参数stickerSets和musicSet。
