我的应用与Android 5不兼容。
当我在任何其他版本中运行它时,它没有任何问题。
这是在Android 5中运行它时在logcat中出现的内容:
"\"
这里的问题在于logcat:
05-16 23:44:10.287 1969-1969/com.barakah.camel E/AndroidRuntime﹕ FATAL EXCEPTION: main
Process: com.barakah.camel, PID: 1969
java.lang.IllegalArgumentException: Spinner adapter view type count must be 1
regionSpinner和categorySpinner都是Spinner类型的对象 ...
public void regionSpinnerSetup() {
ParseQueryAdapter.QueryFactory<ParseObject> factory = new ParseQueryAdapter.QueryFactory<ParseObject>() {
public ParseQuery create() {
ParseQuery query = new ParseQuery("Region");
return query;
}
};
regionAdapter = new ParseQueryAdapter<ParseObject>(getActivity(),
factory);
regionAdapter.setTextKey("name");
regionSpinner.setAdapter(regionAdapter);
regionSpinner.setSelection(1);
regionSpinner.setOnItemSelectedListener(new RegionSpinnerListener());
}
public void CategorySpinnerSetup() {
ParseQueryAdapter.QueryFactory<ParseObject> factory = new ParseQueryAdapter.QueryFactory<ParseObject>() {
public ParseQuery create() {
ParseQuery query = new ParseQuery("Category");
return query;
}
};
categoryAdapter = new ParseQueryAdapter<ParseObject>(getActivity(),
factory);
categoryAdapter.setTextKey("name");
categorySpinner.setAdapter(categoryAdapter);
categorySpinner.setSelection(1);
categorySpinner
.setOnItemSelectedListener(new CategorySpinnerListener());
}
class RegionSpinnerListener implements Spinner.OnItemSelectedListener {
@Override
public void onItemSelected(AdapterView parent, View v, int position,
long id) {
// TODO Auto-generated method stub
ParseObject theSelectedObject = regionAdapter.getItem(position);
Log.e("ABC", "Name is : " + theSelectedObject.getString("name") + " objectId is : " + theSelectedObject.getObjectId());
regionobject = theSelectedObject;
}
知道怎么解决吗?

我没有54b5ed4b967a4e3b96fe8a39
的经验,但是通过阅读它,似乎你可以做这样的事情。
首先,创建一个扩展ParseQueryAdapter
的自己的类,并覆盖ParseQueryAdapter
:
getViewTypeCount()
然后,只有代码中public class MyParseAdapter extends ParseQueryAdapter<ParseObject> {
public MyParseAdapter(Context context, QueryFactory<ParseObject> clazz){
super(context, clazz);
}
@Override
public int getViewTypeCount() {
return 1;
}
}
的每个地方都将其替换为ParseQueryAdapter
:
MyParseAdapter

你无法解决这个问题,因为在lollypop中这个问题是有关系的。所以这个应用程序可以在API 19或更低版本上运行。
如果您正在开发此应用程序,那么只有您可以对项目进行一些小改动。将您的adapter.getViewTypeCount()
更改为1.这是唯一的解决方案。
