为什么我这样写,代码有问题呢?

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b1 = (button)findViewById(R.id.button1);
imageButton1 = (button)findViewById(R.id.imageButton1);
b1.setOnClickListener(new MysetOnClickListener(){
@Override
public void onClick(View v){
super.onClick(v);

}
});
b1.setOnClickListener(new MysetOnClickListener(){
@Override

}
