我的代码是这样的......

public class MainActivity extends Activity {
    String a = new String("1,2,3,4,5")

    private Button button1;
    private Button button2;
    private Button button3;
    private Button button4;
    private Button button5;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        startBtn = (Button) findViewById(R.id.startBtn);

        startBtn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View view) {
                String[] splited=a.split(",");
                for(String b : splited){
                    (button"b").setBackground(Color.RED); 
                   //This is the part where I get stucked//
                    //I know the code is wrong but I just want to express my idea//
                }
            }
        });
    } …
