怎么把xml文件转为java文件

最近我们老大跟我说要我在XML里面写布局,在java中写，不用画出来，就是动态添加就可以了，

然后呢要我提供几个方法，改变文字图片之类的。一时有点懵，后来还是写出来了，以下只供大家参考

因为之前老大让我写了一个MyDesignButton类来继承

AbsoluteLayout，你们也可以继承view或者ViewGruop
//下面是代码，我写的是绝对布局，老大要求的，公司做车载的

public class MyCustomLayout extends MyDesignButton {
    Context context;
   

    private ImageView iv;
    private TextView tv;
    MyDesignButton Mylayout;

    public MyCustomLayout(Context context, AttributeSet attrs) {
        super(context, attrs);

        AbsoluteLayout layout = new AbsoluteLayout(context);

        AbsoluteLayout.LayoutParams lp = new AbsoluteLayout.LayoutParams(152, 182,0,0);
        Mylayout = new MyDesignButton(context, attrs);
        Mylayout.setLayoutParams(lp);
        this.addView(Mylayout);
 iv = new ImageView(context);
        tv = new TextView(context);
        AbsoluteLayout.LayoutParams lp1 = new AbsoluteLayout.LayoutParams(152,152, 0, 0);
        iv.setLayoutParams(lp1);
        Mylayout.addView(iv);
        iv.setImageResource(R.drawable.vehicle_img_101);

        AbsoluteLayout.LayoutParams lp2 = new AbsoluteLayout.LayoutParams(152,34, 0, 152);
        tv.setLayoutParams(lp2);
        Mylayout.addView(tv);

        tv.setTextSize(10);
        tv.setText("11222");
    }


    //这个几个方法
    public void SetChangeText(String string){

        tv.setText(string);
    }
    public void SetChangeImage(int picture){
        iv.setImageResource(picture);
    }
    public void SetChangeTextSize(float size){
        tv.setTextSize(size);
    }
    public void SetTextCenter(){
        tv.setGravity(Gravity.CENTER);
    }
