我從資產文件夾中讀取文本文件時遇到了FileNotFound異常

Question

public class intro extends AppCompatActivity { 

    private StringBuilder text = new StringBuilder(); 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.intro); 
     BufferedReader reader = null; 

     try { 
      reader = new BufferedReader(
        new InputStreamReader(getAssets().open("assets/Introduction.txt"))); 

      // do reading, usually loop until end of file reading 
      String mLine; 
      while ((mLine = reader.readLine()) != null) { 
       text.append(mLine); 
       text.append('\n'); 
      } 
     } catch (IOException e) { 
      Toast.makeText(getApplicationContext(),"Error reading file!", Toast.LENGTH_LONG).show(); 
      e.printStackTrace(); 
     } finally { 
      if (reader != null) { 
       try { 
        reader.close(); 
       } catch (IOException e) { 
        //log the exception 
       } 
      } 

      TextView output= (TextView) findViewById(R.id.intro); 
      output.setText((CharSequence) text); 

     } 
    }

我嘗試了很多打開資產文件夾的路徑，但它顯示filenotfound異常。在這裏，我在Assets文件夾中創建了Introduction.txt文件，並在其上編寫了一些內容。但我無法通過提供路徑或文件名來打開它。

從"assets/Introduction.txt"刪除assets/。提供給open()的路徑是內的相對路徑您的assets/。
