R.string 字符与CharSequence (工作记录)

Notification getProgressNotification(@StringRes int msgId) {
    mProgressTracker.update(mProgressBuilder, (remainingTime) -> service.getString(msgId, FormatUtils.formatDuration(remainingTime)));
    if(mProgressTracker.mRemainingTime>=1000000){
        mProgressBuilder.setContentText();
    }
    return mProgressBuilder.build();
}

mProgressBuilder.setContentText();需要用到R.string中的字符用于各国语言适配

/**
 * Set the second line of text in the platform notification template.
 */
@NonNull
public Builder setContentText(CharSequence text) {
    mN.extras.putCharSequence(EXTRA_TEXT, safeCharSequence(text));
    return this;
}v
其中

CharSequence本身是一个接口，在该接口中有如下方法：

获取指定索引的字符：public char charAt​(int index)；
获取字符串长度：public int length​()；
截取部分字符串：public CharSequence subSequence​(int start, int end)；

我想将R.string中的字符应用到

setContentText()中
方法:

String str;
CharSequence cs;
str=String.valueOf((R.string.Copy_time_dean));
cs=str;

 if(mProgressTracker.mRemainingTime>=1000000){
        mProgressBuilder.setContentText();
    }
    return mProgressBuilder.build(cs);

结果:显示了地址的数字此方法不生效.
使用service获取

Notification getProgressNotification(@StringRes int msgId) {
    String str;
    CharSequence cs;
    str=service.getString(R.string.Copy_time_dean);
    cs=str;
    Log.w(TAG,"CS under =: "+cs);
    mProgressTracker.update(mProgressBuilder, (remainingTime) -> service.getString(msgId, FormatUtils.formatDuration(remainingTime)));
    if(mProgressTracker.mRemainingTime>=1000000){
        mProgressBuilder.setContentText(cs);
        Log.w(TAG,"CS in struct : "+cs);
    }
    return mProgressBuilder.build();
}
解决!!
