我想问一下,我正在和微调器一起工作。我有一个列表视图和一个微调器。在我的微调器中,我声明“月”、“六月”、“七月”、“八月”、“九月”、“十月”、“十一月”、“十二月”
在列表视图中,最初它是空的。当我点击“August”时,它会在列表视图中显示August(august.java)的数据,请问有什么办法吗?
因为现在,我正在上课。意思是,当我点击 Aug 时,它会打开新的意图。但我想将它合并到一个类中,这样当我点击“八月”时,它会在列表视图中发生变化,而不是打开新的意图。有没有办法做到这一点?
这是我的代码
String [] months = {
"June",
"July",
"August",
"Septemeber",
"November",
"December",
我的 date.java 的一部分
//SpinnerView
s1 = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, months);
s1.setAdapter(adapter);
s1.setOnItemSelectedListener(new OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> arg0,View arg1, int arg2, long arg3) {
int index = s1.getSelectedItemPosition();
//Toast.makeText(getBaseContext(), "You have seleted item :" + months[index] , Toast.LENGTH_SHORT).show();
}
public void onNothingSelected(AdapterView<?>arg0) {}
});
if ( s1.equals("August")) {
startActivity(new Intent(date.this,MainActivity.class));
}
else{
startActivity(new Intent(date.this,august
.class));
}
我得到的数据代码。八月.java
public class august extends ListActivity {
String URL = "http://api.eventful.com/rest/events/search?app_key=42t54cX7RbrDFczc&location=singapore&page_size=20&date=august";
