Android:两个 Spinner onItemSelected() [英] Android: two Spinner onItemSelected()

问题描述

我在一个 Activity 中有两个微调器(day_spin 和 time_spin).我想将选定的 day_spin 值保存到一个变量中.是否可以区分同一个 Listener 中的两个微调器?还是我必须为每个微调器编写自己的 Listener 类?

I have two spinners (day_spin and time_spin) in one Activity. I want to save the selected day_spin value into a variable. Is it possible to differenciate between the two spinners in the same Listener? Or do I have to write my own Listener class for each spinner?

我还想获取所选项目的编号.例如，我有 6 个元素的字符串数组.我选择了数字 3.如何获取 ID?

Also I want to get the number of the selected item. For example I have String Array with 6 elements. I select number 3. How can I get the id?

    day_spin = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter<CharSequence> adapter_day = ArrayAdapter
            .createFromResource(this, R.array.spinner_day_array,
                    android.R.layout.simple_spinner_item);
    adapter_day
            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    day_spin.setAdapter(adapter_day);
    day_spin.setOnItemSelectedListener(this);

    time_spin = (Spinner) findViewById(R.id.spinner1);
    ArrayAdapter<CharSequence> adapter_time = ArrayAdapter
            .createFromResource(this, R.array.spinner_time_array,
                    android.R.layout.simple_spinner_item);
    adapter_time
            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    time_spin.setAdapter(adapter_time);
    time_spin.setOnItemSelectedListener(this);

这是我的Listener:

public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
    DAY = parent.getItemAtPosition(pos).toString();
    TIME = parent.getItemAtPosition(pos).toString();
}

希望你能帮帮我！

推荐答案

public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
    if(parent.getId() == R.id.spinner1)
    {
      //do this                    
    }
    else if(parent.getId() == R.id.spinner2)
    {
      //do this
    }
}
