Erstellen Sie benutzerdefinierte Methoden, die auf Objekte von oncreate zugreifen()

Question

Ich versuche, eine Anwendung zu entwickeln, wo ich eine Reihe von Code haben, die jedes Mal aufgerufen werden muss, wenn eine Taste aus 5 Taste gedrückt ist. nur die ID der Datei zugeordneten geöffnet werden damit ändert so muss ich ein Verfahren schaffen, etc. in der onCreate() wie Schaltflächen erstellt alle Objekte zugreifen können

public class Aero extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.aero); 
    final SlidingDrawer slider = (SlidingDrawer) findViewById(R.id.slidingDrawer1); 
    final TextView secondyear = (TextView) findViewById(R.id.ae2yrsyll); 
    final ScrollView scrl = (ScrollView) findViewById(R.id.scrollView1); 
    Button one = (Button) findViewById(R.id.ae_three_sem_am3); 
    Button two = (Button) findViewById(R.id.ae_three_sem_at); 
    Button three = (Button) findViewById(R.id.ae_three_sem_fmm); 
    Button four = (Button) findViewById(R.id.ae_three_sem_cp); 
    Button five = (Button) findViewById(R.id.ae_three_sem_ea); 
    one.setOnClickListener(new OnClickListener() { 

     public void mymethod(int resourse) { 
      scrl.pageScroll(View.FOCUS_UP); 
      InputStream is = getResources().openRawResource(resourse); 
      BufferedReader br = new BufferedReader(
        new InputStreamReader(is)); 
      String line; 
      String entireFile = ""; 
      try { 
       while ((line = br.readLine()) != null) { // <--------- place 
                  // readLine() 
                  // inside loop 
        entireFile += (line + "\n"); // <---------- add each 
                // line to entireFile 
       } 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      secondyear.setText(entireFile); // <------- assign entireFile to 
              // TextView 
      if (slider.isOpened()) { 
       slider.close();

     } 

     @Override

      String line; 
      String entireFile = ""; 
      try {

    two.setOnClickListener(new OnClickListener() {

      secondyear.setText(entireFile); // <------- assign entireFile to

    four.setOnClickListener(new OnClickListener() {

      InputStream is = getResources().openRawResource(R.raw.aero5); 
      BufferedReader br = new BufferedReader(
        new InputStreamReader(is)); 
      String line; 
      String entireFile = ""; 
      try { 
       while ((line = br.readLine()) != null) { // <--------- place 
                  // readLine() 
                  // inside loop 
        entireFile += (line + "\n"); // <---------- add each 
                // line to entireFile 
       } 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      secondyear.setText(entireFile); // <------- assign entireFile to 
              // TextView 
      if (slider.isOpened()) { 
       slider.close(); 
      } 
     } 
    }); 

therfore möchte ich ein erstellen Methode namens myMethod, die wie folgt sein würde

myMethod(int reso){scrl.pageScroll(View.FOCUS_UP); 
      InputStream is = getResources().openRawResource(reso); 
      BufferedReader br = new BufferedReader(
        new InputStreamReader(is)); 
      String line; 
      String entireFile = ""; 
      try { 
       while ((line = br.readLine()) != null) { // <--------- place 
                  // readLine() 
                  // inside loop 
        entireFile += (line + "\n"); // <---------- add each 
                // line to entireFile 
       } 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      secondyear.setText(entireFile); // <------- assign entireFile to 
              // TextView 
      if (slider.isOpened()) { 
       slider.close(); 
      }} 

wo stelle ich diese Methode? Bitte helfen Sie

Speichern Sie Ihre Ansichten in Variablen in der Aktivität und greifen Sie darauf zu.

public class Aero extends Activity { 

    TextView mSecondYear; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.aero); 
     mSecondYear = (TextView) findViewById(R.id.ae2yrsyll); 
     ... 
    } 

    public void myMethod() { 
     mSecondYear.setText("bla"); 
    } 
}
