在Android的5.0微调适配器问题 [英] Spinner adapter issue in Android 5.0

问题描述

我的应用不与Android兼容5

My app is not compatible with Android 5.

当我在其他任何版本上运行它它的工作原理没有问题。

When I run it in any other version it works with no issues.

这是当Android的5运行它什么出现在logcat的：

This is what appears in the logcat when run it in Android 5:

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

下面的问题所在基础上，logcat的：

Here's where the problem lies based on the logcat:

 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;
    }

regionSpinner和categorySpinner两者都是类型微调对象
...

Both regionSpinner and categorySpinner are objects of type Spinner ...

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onActivityCreated(savedInstanceState);
    regionSpinnerSetup();
    CategorySpinnerSetup();

}

不知道如何解决呢？

Any idea how to solve it?

推荐答案

我没有与 ParseQueryAdapter 的经验，但是从它阅读起来，似乎你可以做这样的事情。

I don't have experience with ParseQueryAdapter, but from reading up on it, it seems you could do something like this.

首先，创建自己的类扩展 ParseQueryAdapter ，并覆盖 getViewTypeCount（）：

First, create your own class that extends ParseQueryAdapter, and override getViewTypeCount():

public class MyParseAdapter extends ParseQueryAdapter<ParseObject> {

  public MyParseAdapter(Context context, QueryFactory<ParseObject> clazz){        
        super(context, clazz); 
  }

  @Override
  public int getViewTypeCount() {
     return 1;
  }
}

然后，只需每到一个地方，你有 ParseQueryAdapter 在code，用 MyParseAdapter 替换：

public void regionSpinnerSetup() {
    MyParseAdapter.QueryFactory<ParseObject> factory = new MyParseAdapter.QueryFactory<ParseObject>() {
        public ParseQuery create() {
            ParseQuery query = new ParseQuery("Region");
            return query;
        }
    };

    regionAdapter = new MyParseAdapter<ParseObject>(getActivity(),
            factory);
    regionAdapter.setTextKey("name");
    regionSpinner.setAdapter(regionAdapter);
    regionSpinner.setSelection(1);
    regionSpinner.setOnItemSelectedListener(new RegionSpinnerListener());
}

public void CategorySpinnerSetup() {
    MyParseAdapter.QueryFactory<ParseObject> factory = new MyParseAdapter.QueryFactory<ParseObject>() {
        public ParseQuery create() {
            ParseQuery query = new ParseQuery("Category");
            return query;
        }
    };

    categoryAdapter = new MyParseAdapter<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;
    }
