Android-多纱厂 [英] Android- Multiple Spinners

问题描述

我有这个code：

package lijap.app.starcraft2counters;

import java.io.File;
import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

public class Settings extends Activity implements OnItemSelectedListener {
Spinner answertime;
Spinner gametime;
Spinner missesallowed;

String[] answerseconds = { "Unlimited", "1 second", "2 seconds", "3 seconds",
        "4 seconds", " 5 seconds" };

String[] gameminutes = { "Unlimited", "1 minute", "2 minutes", "3 minutes",
        "4 minutes", " 5 minutes" };

String[] numberofmisses = { "Unlimited", "5", "10", "15",
        "20", "25" };

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.settings);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(Settings.this,
            android.R.layout.simple_spinner_item, gameminutes);

    answertime = (Spinner) findViewById(R.id.s_answertime);
    answertime.setAdapter(adapter);
    answertime.setOnItemSelectedListener(this);
}

@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
        long arg3) {
    // TODO Auto-generated method stub


}

@Override
public void onNothingSelected(AdapterView<?> arg0) {
    // TODO Auto-generated method stub

}
}

我越来越糊涂试图把超过1微调。难道我共享阵列适配器，或做我创建一个新的每一个？怎么样onItemSelected？正如你可以从我的琴弦在上面看到的，我要三纱厂。我将如何做到这一点？

I am getting confused trying to put in more than 1 spinner. Do I share the array adapter, or do I create a new one for each? What about the onItemSelected? As you can see from my strings at the top, I want three spinners. How would I do this?

推荐答案

您可以分享不同的微调 S之间的适配器，如果他们适应了相同的信息。显然，所有的适配器需要适应不同的一组的S 字符串，所以你需要创建一个 ArrayAdapter 为每微调。

You could share the adapter between different Spinners if they adapted the same information. Clearly each of your adapters need to adapt a different set of Strings, so you need to create an ArrayAdapter for each Spinner.

一个 OnItemSelectedListener 将工作3 纱厂（只要你设置）。您可以拨打的getId（）在适配器视图＆LT;＆GT; 作为参数传递知道哪个微调引发的事件。

A single OnItemSelectedListener will work for the 3 Spinners (as long as you set them). You can call getId() on the AdapterView<?> passed as an argument to know which Spinner raised the event.

public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
        long arg3) {
    switch(arg0.getId()){
        case R.id.s_answertime:
            break;
        case ...
    }
}
