我在android studio中有两个脚本，一个用于读取文本文件，以及何时决定如何处理文本文档中的信息。如果我手动运行阅读器，则可以正常运行，但如果尝试使用接口代码，则说找不到文件。 这是阅读器代码
public static Map<String, TreeMap<String, String>> connectionsMap = new TreeMap<String, TreeMap<String,String>>(String.CASE_INSENSITIVE_ORDER) ;
public static void main(String[] args) {
setUp();
}
public static void setUp() {
File file = new File("C:\\Users\\hunte\\AndroidStudioProjects\\Degrees\\Degrees.txt");//file with all the connections
System.out.println(file.exists());
try {
Scanner scanner = new Scanner(file, "UTF-8");
String description = "";
String key="";//key for map of main series
String secondKey="";//key for map of a mian serieses connections
String text = "";
while(scanner.hasNext()) {
String see = scanner.next();
if(see.equals("TITLEEND")) {
key=text;
text="";
}
if(see.equals("CONNECTIONTITLEEND")) {
secondKey=text;
text="";
}
if(see.equals("DESCRIPTIONEND")||see.equals("TERMINATE")) {
description =text;
text="";
mapMaker(key,secondKey,description, false);
}if(!see.equals("TERMINATE")&&!see.equals("CONNECTIONTITLEEND")&&!see.equals("DESCRIPTIONEND")&&!see.equals("TITLEEND")) {
if(text.length()<1)text=see;
else text+=" "+see;
}
}
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(connectionsMap.size());
}
public static void mapMaker(String key, String secondKey, String description, boolean recursed) {
if(!connectionsMap.containsKey(key)) {
connectionsMap.put(key, new TreeMap<String,String>(String.CASE_INSENSITIVE_ORDER));
}if(!connectionsMap.get(key).containsKey(secondKey)) {
connectionsMap.get(key).put(secondKey, description);
}
if(!recursed) {
mapMaker(secondKey,key,description,true);
}
}
它可以找到文件，但是当另一个脚本调用setUp方法时，它将引发文件未找到异常。这是另一个脚本。
public class MainActivity extends AppCompatActivity {
String FirstName, SecondName;
EditText InputOne, InputTwo;
Button submitButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Read.setUp();
InputOne=(EditText) findViewById(R.id.FirstImput);
InputTwo=(EditText) findViewById(R.id.SecondImput);
submitButton=(Button) findViewById(R.id.Submit);
submitButton.setOnClickListener(new android.view.View.OnClickListener(){
@Override
public void onClick(android.view.View v){
FirstName=InputOne.getText().toString();
SecondName=InputTwo.getText().toString();
showToast(String.valueOf(Read.connectionsMap.size()));
}
});
}
public void showToast(String s){
Toast.makeText(MainActivity.this,s,Toast.LENGTH_SHORT).show();
}
}
这是日志
