如何在Toast中获取此charSequence卷？

Question

在Toast中无法找到charSequence卷。

int volume_level= am.getStreamVolume(AudioManager.STREAM_MUSIC);
if (volume_level == 0) {
    CharSequence volume = "Text...";
}
Toast toast = Toast.makeText(context, volume, Toast.LENGTH_SHORT);
toast.show();

注意：忽略此解决方案：

int volume_level= am.getStreamVolume(AudioManager.STREAM_MUSIC);
if (volume_level == 0) {
    CharSequence volume = "Text...";
    Toast toast = Toast.makeText(context, volume, Toast.LENGTH_SHORT);
    toast.show();
}
