Android：将文件从特定字符读取到另一个特定字符

Question

我试图读取资产中的txt文件。该文件的结构如下所示：1 [some text] 1 2 [some text] 2 3 [some text] 3 ...。 我想要做的是阅读[some text]部分对应于一个特定的数字，即如果我通过数字1，我​​会从1读到1.我试过这个，但它没有工作：

AssetManager manager = this.getAssets(); 
    InputStream input = null; 
    InputStreamReader in = null; 
    try { 
     input = manager.open("facil/alexubago/songlyrics.txt"); 
     in = new InputStreamReader(input); 
    } catch (IOException e1) { 
     Log.d("ERROR DETECTED", "ERROR WHILE TRYING TO OPEN FILE"); 
    } 
    try { 
     char current; 
     char current2; 
     String themessage ="" ; 
     while (in.ready()) { 

      final Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/Roland.ttf"); 
      final TextView extField = (TextView) findViewById(R.id.thelyrics); 
      extField.setTypeface(tf); 
      current = (char) in.read(); 
      int a = 1; 
      char b = (char) a; 
      if(current == b){ 
        current2 = (char) in.read(); 
       while(current2 != b){ 
        themessage = themessage+current2;} 
       extField.setText(themessage); 
       Log.d("caracter", ""+current);} 
       Toast.makeText(lyricsfreakgame.this,themessage, Toast.LENGTH_SHORT).show(); 
     } 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

Answer 1

int a = 1; 
char b = (char) a; 

这不转换1至字符 '1'。 b的值是1而不是'1'。你应该做这样的

char b = '1';
