如何使用正则表达式基于fullstops获取子字符串？我们只希望在完全停止后获取数据

Str = “i like cows. I also like camels”
// Regex Code here
Output : “I also like camels”

Answer 1

不需要使用正则表达式。使用private Handler handler = new Handler(Looper.getMainLooper()); private int temperature = 0; private TextView textView; public Runnable runnable = new Runnable() { @Override public void run() { if (textView != null) { textView.setText(String.valueOf(temperature)); } } }; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textView = findViewById(R.id.text); findViewById(R.id.btn_add).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { handler.removeCallbacksAndMessages(runnable); handler.postDelayed(runnable, 1000); if (temperature < 32) { temperature++; } } }); findViewById(R.id.btn_minus).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { handler.removeCallbacksAndMessages(runnable); handler.postDelayed(runnable, 1000); if (temperature > 17) { temperature--; } } }); } @Override protected void onStop() { handler.removeCallbacksAndMessages(runnable); super.onStop(); }方法。

split()

Answer 2

您可以使用此方法：

str1 = 'i like cows. I also like camels'
print(str1.split('.')[1:][0].strip())

输出：

I also like camels

Answer 3

尝试此拆分

String dataIWant = mydata.split（“。”）[1];

结果：我也喜欢骆驼

Answer 4

使用split（'。'）并选择最后一个元素通常会更好，但对于 fun ，这是一个RegEx解决方案：

Answer 5

此String: "abcdefg" Code unit count : 11 Grapheme cluster count: 9选择(?:[.]\s([A-Z].+))
