Can I merge the activity and the viewProxy?

Yes you can. But I'm not sure you want.
The main goal of this architecture is to separate behavior by classes. Yes this create more classes but is that a problem? The code will just be more readable.

An example of how to merge ViewProxy and Activity:

public class FormActivity extends BaseAppCompatActivity
        implements FormDef.IView, View.OnClickListener {

    private FormDef.IPresenter mPresenter;

    @Override
    protected int getContentView() {
        return R.layout.activity_form;
    }

    @Override
    protected BasePresenter newPresenter() {
        FormDef.IDataProvider provider = new FormDataProvider();
        return new FormPresenter(provider, this);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        findViewById(R.id.save_button).setOnClickListener(this);
    }

    @Override
    public void setValueSaved(String text) {
        TextView textView = (TextView) findViewById(R.id.save_value_textview);
        textView.setText(text);
    }

    @Override
    public Context getContext() {
        return this;
    }

    @Override
    public void setPresenter(Base.IPresenter pvBasePresenter) {
        mPresenter = (FormDef.IPresenter) pvBasePresenter;
    }

    @Override
    public void onClick(View v) {
        if (v.getId() == R.id.save_button) {
            EditText editText = (EditText) findViewById(R.id.value_edittext);
            mPresenter.onClickSaveButton(editText.getText().toString());
        }
    }
}

But still, if I was you I will avoid to mix two different classes like that.

Ps: I changed your title for a more explicit one for the others ;)
