如何编辑main activity以外的类中动态添加的按钮

LayoutInflater inflater = LayoutInflater.from(context);
ViewGroup parentLayout = (ViewGroup) inflater.inflate(R.layout.activity_main, null);

Button button = new Button(context);
button.setText("动态按钮");
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 按钮点击事件处理逻辑
    }
});

parentLayout.addView(button);

public interface OnButtonAddedListener {
    void onButtonAdded(ViewGroup parentLayout);
}

public class MainActivity extends AppCompatActivity implements ButtonHelper.OnButtonAddedListener {
    // ...

    @Override
    public void onButtonAdded(ViewGroup parentLayout) {
        setContentView(parentLayout);
    }
}
