如何使用dagger2forandroid将视图注入演示者?

inject 这个 view (Activity object) Presenter . 现在我正在使用Presenter类的setter手动设置视图。我怎么用匕首来达到这个目的?你能给我看一个如何做的示例代码吗?

现在主活动就是这样创建演示者的

public class MainActivity extends AppCompatActivity implements CountPresenter.View, ToastPresenter.View {

    @Inject
    CountPresenter countPresenter;
    @Inject
    ToastPresenter toastPresenter;
    TextView countText;
    Toast toast;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        countText = findViewById(R.id.text_count);

        DaggerToastPresenterComponent.create().inject(this);
        DaggerCountPresenterComponent.create().inject(this);
        countPresenter.setView(this);
        toastPresenter.setView(this) ;

        findViewById(R.id.button_count).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                countPresenter.incrementCount();
            }
        });

        findViewById(R.id.button_toast).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                toastPresenter.handleToastButtonClick();
            }
        });
    }
}

public class CountPresenter {
    private Counter counter ;


    public void setView(View view) {
        this.view = view;
    }

    private View view ;

    @Inject
    public CountPresenter() {
        counter =  Counter.getInstance() ;
    }

    public void incrementCount(){
        counter.setCount(counter.getCount()+1);
        view.setCounterText(counter.toString());
    }

    public interface View {
        void setCounterText(String val) ;
    }
}
