只顯示文本中的數字

我有一個既有字母又有數字的字符串。只顯示文本中的數字

如下圖所示：

我想從字母分離號碼和當用戶點擊的數字這些數字被顯示在屏幕的按鈕上。

如下面的照片：

我有一個的活動，藉此到另一個字符串活動。

基本上我該怎麼辦？謝謝。

我的活動1：

public class BoxActivity extends AppCompatActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.box); 
    TextView textView = (TextView) findViewById(R.id.txtView); 
    Bundle bundle = getIntent().getExtras(); 
    if(bundle != null){ 
     String strBox = bundle.getString("fln"); 
     textView.setText(strBox); 
    } 

}

看一看在該線程http://stackoverflow.com/questions/1558432/extracting-一個數字從一個字符串在Java和也是http：//stackoverflow.com/questions/10734989/extract-numbers-from-an-alpha-numeric-string-using-android ... – chirag90

達達， mikhay faghat shomararo neshoon bede？阿蘭奇奈舒恩？ – nafas

使用英語，所以每個人都可以讀它 –

你應該使用正則表達式從字符串

Pattern p = Pattern.compile("-?\\d+"); 
Matcher m = p.matcher("There are more than -2 and less than 12 numbers here"); 
while (m.find()) { 
System.out.println(m.group()); 
}

exgtract上視圖點擊收聽號碼，你可以做到這一點。

@Override 
void onClick(View view){ 
String allTxt = editText.getText.toString() 
Pattern p = Pattern.compile("-?\\d+"); 
    Matcher m = p.matcher(allTxt); 
    while (m.find()) { 
    System.out.println(m.group());//here are the numbers then you can set it to another TextView 
    } 
}

String str = "test-asdfdfg 455 yuoyr 4";  
str = str.replaceAll("[^-?0-9]+", " "); 
System.out.println(Arrays.asList(str.trim().split(" ")));

輸出[455，4]使用此陣列來顯示選擇器
