为什么我的自定义getView未被调用？

Question

我不熟悉制作自定义适配器，但是我已经看到并遵循了我在线看到的很多示例。我不知道为什么我的getView没有被调用。

下面是代码：

private String[] numbers = new String[] { 

"42", "0", "0", "39", "32", "0", "0", "0", "0", "0", "0", "0", "0", "0", 
     "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "45", "0", "51", 
     "36", "35", "20", "0", "22", "0", "53", "0", "1", "2", "0", "16", 
     "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "5", 
     "6", "0", "0", "0", "57", "0", "0", "64", "7", "0", "0", "0" }; 



@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
//other code 
grid = (GridView) findViewById(R.id.GridViewGame); 
    CustomArrayAdapter adapter = new CustomArrayAdapter(this, 
      R.layout.item_layout, R.id.editTextGridItem, numbers); 
    grid.setAdapter(adapter); 

的CustomArrayAdapter类：

public class CustomArrayAdapter extends ArrayAdapter<String> { 

public CustomArrayAdapter(Context context, int resource, 
     int textViewResourceId, Object[] objects) { 

    super(context, resource, textViewResourceId); 

} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    View v = convertView; 
    if (v == null) { 
     LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     v = inflater.inflate(R.layout.item_layout, null); 
    } 
    else{ 
    v.setTag(Integer.toString(position)); 
    System.out.println(v.getTag()); 
    } 
    return v; 
} 

总体什么，我想设置一个视图到GridView（在我来说，每一个细胞都含有1 EDITTEXT）时发生这种情况我想分配editText一个将匹配它在数字[]中的位置的标签。我不确定你的代码我现在会这样做，但因为getView永远不会被调用

您还没有将对象数组传递给父ArrayAdapter类，所以它认为有零个项目要显示。

构造函数改成这样：

public class CustomArrayAdapter extends ArrayAdapter<Object> { 

    public CustomArrayAdapter(Context context, int resource, 
     int textViewResourceId, Object[] objects) { 

     super(context, resource, textViewResourceId, objects); 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View v = convertView; 
     if (v == null) { 
      LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      v = inflater.inflate(R.layout.item_layout, null); 
     } 
     else{ 
     v.setTag(Integer.toString(position)); 
     System.out.println(v.getTag()); 
     } 
     return v; 
    } 
}
