[英]removing words from a string in java
誰能告訴我代碼中的錯誤嗎?
我試圖將字符串傳遞給函數removeWords()
並且此函數從String
刪除一些信息。
例如,如果我通過:
“我有頭痛”
該函數應返回:
“頭痛”
但是,我的功能不起作用:
public class WordChosen extends Activity {
private TextView wordsList;
private String symptom;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_word_chosen);
//Getting String from VoiceRecognition Activity and displaying it
Intent intent = getIntent();
String wordChosen = intent.getExtras().getString("wordChosen");
//casting the string with TextView to display the result
wordsList = (TextView) findViewById(R.id.wordChosen);
Log.v("Word List:", "+++++"+wordChosen);
//Setting text to be displayed in the textView
removeWords(wordChosen);
Log.v("removewords:", "------- message is displayed");
}
public void removeWords(String wordList)
{
ArrayList<String> stopList = null;
stopList.add("i");
stopList.add("have");
stopList.add("a");
ArrayList<String> result = new ArrayList<String>(Arrays.asList(wordList.split(" ")));
for(int i=0; i<result.size();i++)
{
for(int j=0; j<stopList.size();j++)
{
if (result.get(i).equals(stopList.get(j))) {
break;
}
else {
if(j==stopList.size()-1)
{
wordsList.setText(result.get(i));
}
}
}
}
}
}
public static void main(String[] args) {
String word = "I Have a Headach";
String remove = "I Have a ";
System.out.println(removeWords(word, remove));
}
public static String removeWords(String word ,String remove) {
return word.replace(remove,"");
}
輸出: Headach
