我想做一个2个微调器活动,第二个微调器依赖于第一个微调器,类似于州/城市示例。我用字符串数组填充了微调器,所以继承我的
的strings.xml
<string-array name="Jornadas">
<item >1</item>
<item >2</item>
<item >3</item>
<item >4</item>
<item >5</item>
</string-array>
<string-array name="partidosj1">
<item >c11</item>
<item >c12</item>
<item >c15</item>
<item >c13</item>
</string-array>
<string-array name="partidosj2">
<item >c1</item>
<item >c2</item>
<item >c5</item>
<item >c3</item>
</string-array>
//and so on....
继承我的oncreate
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Spinner jornadas = (Spinner) findViewById(R.id.spinner1);
Spinner partidos = (Spinner) findViewById(R.id.spinner2);
ArrayAdapter adapter1 = ArrayAdapter.createFromResource(this, R.array.Jornadas, android.R.layout.simple_spinner_item);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
jornadas.setAdapter(adapter1);
jornadas.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
String a= "partidosj "+pos;
}
});
ArrayAdapter adapter2 = ArrayAdapter.createFromResource(this,R.array.a, android.R.layout.simple_spinner_item);
//Do whatever
}}
因此字符串“a”与我想要填充第二个微调器的字符串数组具有相同的名称,但我不能在数组适配器上引用它,因为它必须是一个int变量。有没有办法将“a”变量转换为正确的字符串数组资源?
非常感谢!

你去了:
int arrayId = getResources().getIdentifier(a, "array", getPackageName());
