Android的：两个微调onItemSelected（） [英] Android: two Spinner onItemSelected()

问题描述

我有两个纱厂（day_spin和time_spin）在一个活动。我想选择的day_spin值保存到一个变量。是否有可能在同一个监听器两纺纱之间者区分？还是我写我自己的监听器类的每个微调？

此外，我想获得所选项目的数量。比如我有6个元素字符串数组。我选择3号。我怎样才能得到的ID？

  day_spin =（微调）findViewById（R.id.spinner）;
    ArrayAdapter＆LT; CharSequence的＆GT; adapter_day = ArrayAdapter
            .createFromResource（这一点，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（本）;

    time_spin =（微调）findViewById（R.id.spinner1）;
    ArrayAdapter＆LT; CharSequence的＆GT; adapter_time = ArrayAdapter
            .createFromResource（这一点，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（本）;
 

这是我的监听器：

 公共无效onItemSelected（适配器视图＆LT;＆GT;母公司视图中查看，诠释POS，长I​​D）{
    DAY = parent.getItemAtPosition（POS）的ToString（）;
    TIME = parent.getItemAtPosition（POS）的ToString（）;
}
 

我希望你能帮帮我！

解决方案

 公共无效onItemSelected（适配器视图＆LT;＆GT;母公司视图中查看，诠释POS，长I​​D）{

     微调微调=（微调）父母;
     如果（spinner.getId（）== R.id.spinner1）
     {
       //做这个
     }
     否则，如果（spinner.getId（）== R.id.spinner2）
     {
       //做这个
     }

}
 

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?

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);

This is my Listener:

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

I hope you can help me!

解决方案

public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

     Spinner spinner = (Spinner) parent;
     if(spinner.getId() == R.id.spinner1)
     {
       //do this                    
     }
     else if(spinner.getId() == R.id.spinner2)
     {
       //do this
     }

}
