我已经关注了其他一些问题并将其拼凑起来得到这个：
public class FbFPS extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fbhtf);
ArrayAdapter<CharSequence> adapter = ArrayAdapter
.createFromResource(this, R.array.spagesarray,
android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner s = (Spinner) findViewById(R.id.spages);
s.setAdapter(adapter);
s.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// Display Selected option
if (parent.getItemAtPosition(pos).toString()
.equals("Under 16s Reccommended Settings")) {
Intent i = new Intent(getApplicationContext(),
FbU16RS.class);
startActivity(i);
finish();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
s.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// Display Selected option
if (parent.getItemAtPosition(pos).toString()
.equals("Recommended Privacy Settings")) {
Intent i = new Intent(getApplicationContext(), FbRS.class);
startActivity(i);
finish();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
}
还有两个类似的活动，但它们指向剩余的两个活动。所以基本上是这样的：
s.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// Display Selected option
if (parent.getItemAtPosition(pos).toString()
.equals("Recommended Privacy Settings")) {
Intent i = new Intent(getApplicationContext(), FbRS.class);
startActivity(i);
finish();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
每次活动两次。清单中提到了它们，并且 xml 是正确的。虽然它打开了最后一个选项，但确实打开了另一个选项，但它真的很奇怪。当在那个开始的时候，它不会打开任何......
我哪里错了？我也愿意接受任何更简单的方法。：） 提前致谢。
编辑：
好的，我已经在所有 3 个活动上进行了更改，现在它似乎在我选择的任何内容上都打开了相同的活动。这是代码：
public class FbRS extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fbhtf);
final Intent iFbHTF = new Intent(FbRS.this, FbHTF.class);
final Intent iFbU16RS = new Intent(FbRS.this, FbU16RS.class);
ArrayAdapter<CharSequence> adapter = ArrayAdapter
.createFromResource(this, R.array.spagesarray,
android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner s = (Spinner) findViewById(R.id.spages);
s.setAdapter(adapter);
s.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
if (parent.getItemAtPosition(pos).toString()
.equals("Finding Privacy Settings")) {
startActivity(iFbHTF);
finish();
} else if (parent.getItemAtPosition(pos).toString()
.equals("Under 16s Recommended Privacy Settings")) {
startActivity(iFbU16RS);
finish();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
}
这里还有清单：

我认为它到达那里希望感谢 AndroidPenguin 和 kongkea 的帮助。
