Question

您好我一直在尝试使用自定义列表项目布局的自定义列表活动，我迫切需要帮助。我用作列表适配器的自定义适配器类可能是错误的或者是正确的，但无论是什么方法，getView（）都没有被使用，当我将日志放入其中时它没有显示，我的适配器类是这样的：

private class MyAdapter extends ArrayAdapter<String>{

    int position1;

    public MyAdapter(Context context, int resource,int pos) {
        super(context, resource);
        position1 = pos;
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View row = inflater.inflate(R.layout.privatep_single_list_item, parent, false);
        String[] general_Items = new String[Items.length()] ;
        String[] financial_Items = new String[Items.length()] ; 
        String[] address_Items = new String[Items.length()] ; 
        StringBuilder general_sb = new StringBuilder();
        StringBuilder financial_sb = new StringBuilder();
        StringBuilder address_sb = new StringBuilder();
        if(position1 == 0){
        try{
        for(int i = 0; i < Items.length(); i++){

                general_sb.append(Items.getJSONObject(i).getString("Area").toString());
                general_sb.append(" متر ");
                general_sb.append(Items.getJSONObject(i).getString("Bedrooms").toString());
                general_sb.append(" خواب ");
                general_sb.append(Items.getJSONObject(i).getString("CA").toString());
                general_sb.append(" ساخت ");

                financial_sb.append("متری ");
                financial_sb.append(Items.getJSONObject(i).getString("OPPM").toString());
                financial_sb.append(" تومان");

                address_sb.append(Items.getJSONObject(i).getString("address").toString());

                general_Items[i] = general_sb.toString();
                financial_Items[i] = financial_sb.toString();
                address_Items[i] = address_sb.toString();

        }}
        catch (Exception e){
            Log.e("Fail 3", e.toString());
        }
        } else if (position1 == 1){

            try{
                for(int i = 0; i < Items.length(); i++){

                        general_sb.append(Items.getJSONObject(i).getString("Area").toString());
                        general_sb.append(" متر ");
                        general_sb.append(Items.getJSONObject(i).getString("Bedrooms").toString());
                        general_sb.append(" خواب ");
                        general_sb.append(Items.getJSONObject(i).getString("CA").toString());
                        general_sb.append(" ساخت ");

                        financial_sb.append("کرایه ");
                        financial_sb.append(Items.getJSONObject(i).getString("Rent").toString());
                        financial_sb.append(" /n");
                        financial_sb.append("رهن ");
                        financial_sb.append(Items.getJSONObject(i).getString("PrePayment").toString());

                        address_sb.append(Items.getJSONObject(i).getString("address").toString());

                        general_Items[i] = general_sb.toString();
                        financial_Items[i] = financial_sb.toString();
                        address_Items[i] = address_sb.toString();

                }}
                catch (Exception e){
                    Log.e("Fail 3", e.toString());
                }
        } else if (position1 == 2){
            try{
                for(int i = 0; i < Items.length(); i++){

                        general_sb.append(Items.getJSONObject(i).getString("Area").toString());
                        general_sb.append(" متر ");
                        general_sb.append(Items.getJSONObject(i).getString("Bedrooms").toString());
                        general_sb.append(" خواب ");
                        general_sb.append(Items.getJSONObject(i).getString("CA").toString());
                        general_sb.append(" ساخت ");

                        financial_sb.append("رهن ");
                        financial_sb.append(Items.getJSONObject(i).getString("Price").toString());

                        address_sb.append(Items.getJSONObject(i).getString("address").toString());

                        general_Items[i] = general_sb.toString();
                        financial_Items[i] = financial_sb.toString();
                        address_Items[i] = address_sb.toString();

                }}
                catch (Exception e){
                    Log.e("Fail 3", e.toString());
                }
        }


        TextView general_text = (TextView) row.findViewById(R.id.General_Info);
        TextView financial_text = (TextView) row.findViewById(R.id.Financial_Info);
        TextView address_text = (TextView) row.findViewById(R.id.Address_Info);

        general_text.setText(general_Items[position]);
        financial_text.setText(financial_Items[position]);
        address_text.setText(address_Items[position]);

        return super.getView(position, convertView, parent);
    }
}

这是我的适配器构造

protected void onCreate(Bundle savedInstanceState) {        
    super.onCreate(savedInstanceState);
    setContentView(R.layout.privatep);
    setListAdapter(new MyAdapter(this,android.R.layout.simple_list_item_1,0));

    Spinner spinner = (Spinner) findViewById(R.id.select_Spinner);

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
            R.array.select_Options_personal, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);

    spinner.setOnItemSelectedListener(this);


}

我将非常感谢您对此事的评论。

而不是这样做 - ＆gt; return super.getView(position, convertView, parent); 您应该返回变量行，因为这是您自己构建的ui视图。 getView（）方法中的return row;

未使用自定义列表适配器中的getView（）方法
