Question

我想以基本格式编写ListView但我收到错误：

UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

和

androidview.LayoutInfalater.inflate(LayoutInflater.java: some numbers....like 720,658...so on)

我知道应该在适配器类中完成一些事情：

public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    RelativeLayout rv = new RelativeLayout(c);

    TextView tv = new TextView(c);
    TextView tv1 = new TextView(c);
    ImageView imgv = new ImageView(c);

    tv.setText(s[position]);
    tv1.setText(i[position]);
    imgv.setImageResource(d[position]);

    rv.addView(tv);
    rv.addView(tv1);
    rv.addView(imgv);
    return rv;

}

我该怎么做才能解决问题

Answer 1

我该怎么办？

更正您的代码。

UnsupportedOperationException：addView（View，LayoutParams）不是 AdapterView支持

像AdapterView 这样的ListView的子类不能在布局文件中手动添加子项或在代码中添加子项。所以，如果你在一个布局中有这个：

<ListView // .. other attributes>
     <// other views <-- notice the children of the ListView tag
</ListView>

不要这样做，因为这会调用addView的{{1}}方法，抛出异常。而是使用：

ListView

你也在代码中使用<ListView // .. other attributes /> < // other views addView方法中的任何一种方法：

ListView

此外，如果您在listViewReference.addView(anotherView); // <-- don't do it或适配器（其LayoutInflater.inflate方法）的代码中使用Activity方法，则不会传递 getView作为第二个参数。例如，不使用：

ListView

像在Tamilarasi Sivaraj的回答一样，这将再次引发异常。而是使用：

convertView  = inflator.inflate(R.layout.child_rows, parent);

与您在问题中发布的异常相关，您似乎使用convertView = inflator.inflate(R.layout.child_rows, parent, false);方法setText（其中一个int或s数组为{ {1}}数组）。问题是，在这种情况下，i会认为您正在尝试使用像int这样的字符串资源来设置文本。您传递的TextView不是字符串资源，因此会抛出异常。如果R.string.astring或int是s而您试图在i中显示，请改用：

int

Answer 2

替换inflater中的布局

 @Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub

    if (convertView == null) {

        LayoutInflater inflater = (LayoutInflater) LayoutInflater
                .from(contex);
        convertView = inflater.inflate(R.layout.your_layout, parent, false);

    }

    txtName = (TextView) convertView.findViewById(R.id.txtName);
    txtName.setText(""+ContactsArr.get(position).get("ContName"));
    txtPhoneNumber = (TextView) convertView.findViewById(R.id.txtContact);
    txtPhoneNumber.setText(""+ContactsArr.get(position).get("ContPhone"));

    return convertView;
}

Answer 3

如果您喜欢我，并完全跳过我在@Lacksprog的答案中所需要的答案，因为它已经埋没在其中，请尝试将第三个参数添加到inflate方法，也提到here：

inflater.inflate(R.layout.group_row, parent, false);

请勿使用true代替false，否则您会收到相同的错误，因为它会尝试将其附加/添加到父级，因此addView is not supported in AdapterView错误。

Answer 4

试试这样：

public static class ViewHolder {
    public ImageView imageView;
    public TextView textView; 

    public View getView(int position, View convertView, ViewGroup parent) {
        try{
            ViewHolder holder;

            if (convertView == null)  {
                holder = new ViewHolder(); 
                LayoutInflater inflater = context1.getLayoutInflater();
                convertView = inflater.inflate(R.layout.your_layout, null,true);  

                holder.imageView = (ImageView) convertView.findViewById(R.id.imgview);

                holder.textView = (TextView) convertView.findViewById(R.id.txtview);

                convertView.setTag(holder);  
            } else {
                holder = (ViewHolder) convertView.getTag();  
            }

            holder.textView.setText("your text");
            holder.imageView.setImageResource("your image resource");
        } catch (Exception e) {
            System.out.println("Error: "+e);    
        }

        return convertView;
    }
}

Answer 5

我也收到了这个问题：

<块引用>

android.view.InflateException：二进制 XML 文件第 2 行：addView(View, LayoutParams) 在 AdapterView 中不受支持，原因是： java.lang.UnsupportedOperationException: addView(View, LayoutParams) AdapterView 不支持

我在给 .xml 充气时忘记添加 "false"。添加后它就可以工作了。我的代码短语如下。我为我的 LinearLayout 使用了 .xml。

if(convertView == null){
        convertView = LayoutInflater.from(getContext()).inflate(R.layout.row_format,parent,false);
    }

无法启动活动：UnsupportedOperationException：AdapterView不支持addView（View，LayoutParams）
