android可搜索旋转适配器中的问题

Question

我正在我的应用程序中集成可搜索的旋转器。下面是我的代码

    compile 'com.toptoche.searchablespinner:searchablespinnerlibrary:1.3.1'

Xml文件

 <com.toptoche.searchablespinnerlibrary.SearchableSpinner
    android:id="@+id/spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:hintText="Select Country"/>

Man.java

public class MainActivity extends AppCompatActivity {

SearchableSpinner mSearchableSpinner;
ArrayList<GetCountry> mGetCountries;
PriorityAdapter mPriorityAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mSearchableSpinner = (SearchableSpinner) findViewById(R.id.spinner);

    mGetCountries = new ArrayList<>();
    GetCountry mGetCountry = new GetCountry();
    mGetCountry.setId("1");
    mGetCountry.setName("India");
    mGetCountries.add(mGetCountry);

    GetCountry mGetCountry2 = new GetCountry();
    mGetCountry2.setId("2");
    mGetCountry2.setName("USA");
    mGetCountries.add(mGetCountry2);


    GetCountry mGetCountry3 = new GetCountry();
    mGetCountry3.setId("3");
    mGetCountry3.setName("UK");
    mGetCountries.add(mGetCountry3);

    GetCountry mGetCountry4 = new GetCountry();
    mGetCountry4.setId("4");
    mGetCountry4.setName("CHINE");
    mGetCountries.add(mGetCountry4);

    GetCountry mGetCountry5 = new GetCountry();
    mGetCountry5.setId("5");
    mGetCountry5.setName("MALASIYA");
    mGetCountries.add(mGetCountry5);

    mPriorityAdapter=new PriorityAdapter(mGetCountries);
    mSearchableSpinner.setAdapter(mPriorityAdapter);
}


public class PriorityAdapter extends ArrayAdapter<GetCountry> {

    ArrayList<GetCountry> list;

    public PriorityAdapter(ArrayList<GetCountry> list) {
        super(MainActivity.this, R.layout.spin_layout, list);
        this.list = list;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) { // Ordinary


        return initView(position, convertView, parent);
    }

    @Override
    public View getDropDownView(int position, View convertView,
                                ViewGroup parent) { // This view starts when we click the
        // spinner.
        return initView(position, convertView, parent);
    }

    public View initView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflator = getLayoutInflater();
        convertView = inflator.inflate(R.layout.spin_layout, null);
        TextView mTextView = (TextView) convertView
                .findViewById(android.R.id.text1);
        mTextView.setText(list.get(position).getName());
        return convertView;
    }

}

}

当我运行上面的代码时，我得到的输出如下图所示。自定义arraylist数据不显示它是打印java每个项目旋转器输出的垃圾值

    public class PriorityAdapter extends ArrayAdapter<GetCountry> {

    ArrayList<GetCountry> list;

    public PriorityAdapter(ArrayList<GetCountry> list) {
        super(MainActivity.this, R.layout.spin_layout, list);
        this.list = list;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) { // Ordinary


        return initView(position, convertView, parent);
    }

    @Nullable
    @Override
    public GetCountry getItem(int position) {
        return super.getItem(position);
    }



    @Override
    public View getDropDownView(int position, View convertView,
                                ViewGroup parent) { // This view starts when we click the

        View view = convertView;
        LayoutInflater layoutInflater = LayoutInflater.from(getContext());
        view = layoutInflater.inflate(R.layout.spin_layout_1, parent, false);

        TextView tv= (TextView) view.findViewById(R.id.text1);
        tv.setText(list.get(position).getName());
        return view;

    }

    public View initView(int position, View convertView, ViewGroup parent) {


        View view = convertView;
        LayoutInflater layoutInflater = LayoutInflater.from(getContext());
        view = layoutInflater.inflate(R.layout.spin_layout_1, parent, false);

        TextView tv= (TextView) view.findViewById(R.id.text1);
        tv.setText(list.get(position).getName());
        return view;
    }

}

public class GetCountry {
String name;
String id;

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}
}

Answer 1

您可以重写模型（GetCountry）的toString（）函数，如下所示：

getCountry.java

public class GetCountry {
    String name;
    String id;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    @Override
    public String toString() {
        return name;
    }
}
