答

而不是创建不同的选择监听器，实现与onItemSelectedListener它会为您提供方法

@Override 
    public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) { 
if(view==sp1){//do something} 
    } 

    @Override 
    public void onNothingSelected(AdapterView<?> adapterView) { 

    }

和你的OnCreate

活动

sp1.setOnItemSelectedListener(this); 
sp2.setOnItemSelectedListener(this);
