如何在Android編程中使用數組索引列表？

Question

我利用數組列表imageView shuffle，如何將輸入列表中的數組索引值轉換爲if條件？示例代碼如下，但如果條件不想走路，解決方案是什麼？

這是代碼：（。soal.equals（list.get（0））& & text.getText（）的toString（）等於（ 「1」））如果

public class tebakgambar extends Activity implements OnClickListener { 

    private Button ok; 
    private ImageView soal; 
    private EditText text; 

    ArrayList<Integer> list = new ArrayList<Integer>() {{ 
     add(R.drawable.siji); 
     add(R.drawable.loro); 
     add(R.drawable.telu); 
     add(R.drawable.papat); 
     add(R.drawable.limo); 
     add(R.drawable.enem); 
     add(R.drawable.pitu); 
     add(R.drawable.wolu); 
     add(R.drawable.songo); 
     add(R.drawable.nol); 
    }}; 



    /** 
    * Called when the activity is first created. 
    */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.soal); 


     soal = (ImageView) findViewById(R.id.imageView); 
     text = (EditText) findViewById(R.id.editText); 
     ok = (Button) findViewById(R.id.button); 

     ok.setOnClickListener(this); 
    } 
    public void onClick(View v) { 
     acak(); 
     jawaban(); 

    } 

    private void acak(){ 

     Collections.shuffle(list); 
     soal.setImageResource(list.get(0)); 
     soal.setTag(list.get(0)); 

    } 

    private void jawaban() { 

     if (soal.equals(list.get(0)) && text.getText().toString().equals("one")) { 
      text.setText(""); 
      // get your custom_toast.xml ayout 
      LayoutInflater inflater = getLayoutInflater(); 

      View layout = inflater.inflate(R.layout.custom_toast, 
        (ViewGroup) findViewById(R.id.custom_toast_layout_id)); 

      // set a dummy image 
      ImageView image = (ImageView) layout.findViewById(R.id.image); 
      image.setImageResource(R.drawable.benar); 

      // set a message 
      // TextView text = (TextView) layout.findViewById(R.id.text); 
      //text.setText("Benar"); 

      // Toast... 
      Toast toast = new Toast(getApplicationContext()); 
      toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0); 
      toast.setDuration(Toast.LENGTH_LONG); 
      toast.setView(layout); 
      toast.show(); 
     } else { 
      text.setText(""); 
      LayoutInflater inflater = getLayoutInflater(); 

      View layout = inflater.inflate(R.layout.custom_toast, 
        (ViewGroup) findViewById(R.id.custom_toast_layout_id)); 

      // set a dummy image 
      ImageView image = (ImageView) layout.findViewById(R.id.image); 
      image.setImageResource(R.drawable.salah); 

      // set a message 
      // TextView text = (TextView) layout.findViewById(R.id.text); 
      //text.setText("Benar"); 

      // Toast... 
      Toast toast = new Toast(getApplicationContext()); 
      toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0); 
      toast.setDuration(Toast.LENGTH_LONG); 
      toast.setView(layout); 
      toast.show(); 
     } 
    }

如果我正確理解你的問題，

soal.equals(list.get(0)) 

是錯誤的。 「soal」是一個ImageView對象，您將它與Integer等同（因爲ArrayList是Integer類型的）。這在任何方面都是不正確的。

你需要這樣做，

soal.getId().equals(list.get(0)) 

我不知道你的代碼邏輯的其餘部分，但這應該工作。
