Question

J'obtiens une erreur de compilation dans mon onClick .

Voici le code.

public class fieldsActivity extends Activity {

Button addSiteButton;
Button cancelButton;
Button signInButton;

/**
 * Called when the activity is first created.
 */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // to create a custom title bar for activity window
    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);

    setContentView(R.layout.fields);
    // use custom layout title bar
    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.topbar);

    Pager adapter = new Pager();
    ViewPager mPager = (ViewPager) findViewById(R.id.fieldspager);
    mPager.setAdapter(adapter);
    mPager.setCurrentItem(1);

    addSiteButton = (Button) findViewById(R.id.addSiteButton);
    addSiteButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
           mPager.setCurrentItem(2, true); //Compilation error happens here.
        }

    });

    cancelButton = (Button) findViewById(R.id.cancel_button);

    public class ConfigureActivity extends Activity {

        EditText etOne;
        EditText etTwo;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_configure);

            Button btnConfigure = findViewById(R.id.btnConfigure1);   
            btnConfigure.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            configure();
                        }
                    });
    }

    public  void configure(){
            String one = etOne.getText().toString();
            String two = etTwo.getText().toString();
    }
}
