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

Question

我想写一个ListView基本格式,但我收到一个错误:

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？？？

纠正你的代码.

UnsupportedOperationException:AdapterView不支持addView(View,LayoutParams)

AdapterView类似a 的子类ListView 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,因为这将调用抛出异常的addView方法ListView.而是使用:

<ListView // .. other attributes />
< // other views

您也不能使用代码中的任何addView方法,ListView如下所示:

listViewReference.addView(anotherView); // <-- don't do it

此外,如果您LayoutInflater.inflate在Activity或适配器的代码(其getView方法)中使用该方法,请不要将其ListView作为第二个参数传递.例如,不要使用:

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

就像在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, false);

与您在问题中发布的异常相关,您似乎使用该setText方法int(其中一个s或i数组是一个int数组).问题是,在这种情况下,TextView您会认为您正在尝试使用像这样的字符串资源来设置文本R.string.astring.在int您传递不是一个字符串资源,以便一个异常将被抛出.如果s或者i是,int并且您试图在TextView使用中显示它而不是:

tv.setText(String.valueOf(s[position])); // assuming s is the int array

Answer 2

在inflater中替换您的布局

 @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

如果你像我一样,完全跳过我在@Lacksprog的答案中所需要的答案,因为它被埋在里面,试着在inflate方法中添加第三个参数,这里也提到:

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

不要使用true代替false或者你会得到相同的错误,因为它试图将它附加/添加到父,因此addView is not supported in AdapterView错误.
