android - 微调器 setOnItemSelectedListner 在创建活动时触发

Question

创建活动后，将自动调用微调器setOnItemSelectedListner()事件。如何停止此自动呼叫。

Answer 1

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    int count=0;
    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        if(count >= 1){
        //do something
        }
        count++;
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
    }
});
