我该如何解决这个错误.底部的所有三个字符串都会出现以下错误"对于Apps类型,方法getString(int)未定义".请帮忙,我是这样的菜鸟.

package com.actionbarsherlock.sample.fragments;

import android.content.Context;
import android.content.res.Resources;


public final class Apps {
/**
 * Our data, part 1.
 */
public static final String[] TITLES =
{
        "title1",
        "title2",
        "title3"
};

/**
 * Our data, part 2.
 */
public static final String[] DIALOGUE = { 

    getString(R.string.text1),

    getString(R.string.string2),

    getString(R.string.string3)

};
}

我在尝试对定义的函数启用 numba 优化时遇到错误。

这是简化的函数：

@jit
def monte_carlo(iterations):
    key1 = []
    key2 = []
    score = []
    for i in range(iterations):
        random.seed(i)
        temp_matrix = random.sample(matrix, length)

        for j in range(iterations):
            random.seed(j)
            key2.append(i)
            key1.append(j)

            for x in range(...):
                try: temp_matrix[x] = random.sample(matrix[x], len(matrix[x]))
                except: continue


        scores.append(...)
    return scores, keyA, keyB

monte_carlo(1000)

然后我收到这个错误，在使用 Cuda 而不是 Jit 时也遇到了问题。

Traceback (most recent call last):
  File "..."
  File ...\numba\dispatcher.py", line 404, in _compile_for_args
    error_rewrite(e, 'unsupported_error')
  File "...\numba\dispatcher.py", line 344, in error_rewrite

给定客户的电子邮件地址，我如何访问他们的订阅，特别是他们的订阅状态。我只提供 1 项订阅服务，因此任何查询都只能显示一项结果。

例如

import stripe  

def functionA(customer_email):
    ...
    return customer_sub

sub  = stripe.Subscription.retrieve(functionA("xyz@gmail.com"))
status = sub.status

好的,这是一个菜鸟问题.如何设置列表视图,点击时最好在新页面上显示描述.截至目前,应用程序仅打开并显示菜单,每次更改标题部分时,它都会更改页码.
