无法启动活动:UnsupportedOperationException:AdapterView 不支持 addView(View, LayoutParams) [英] Unable to start activity:UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView
问题描述
我想以基本格式编写ListView，但出现错误:
I want to write a ListView in basic format but I get an error:
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做一些事情:
I know something should be done here in the adapter class:
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;
}
我应该怎么做才能解决问题
What should I do to solve the problems

推荐答案
我该怎么办???
what should i do???
更正您的代码.
UnsupportedOperationException: addView(View, LayoutParams) 不是AdapterView 支持
UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView
AdapterView 的子类，如 ListView 不能在布局文件中或在代码中手动添加子类.因此，如果您在其中一种布局中有此功能:
A subclass of AdapterView like a ListView can't have children manually added either in the layout file or added in code. So if you have this in one of your layouts:
<ListView // .. other attributes>
<// other views <-- notice the children of the ListView tag
</ListView>
不要这样做，因为这会调用ListView的addView方法，抛出异常.而是使用:
don't do it, as this will call the addView method of ListView, throwing the exception. Instead use:
<ListView // .. other attributes />
< // other views
你也不能在这样的代码中使用ListView的任何addView方法:
You also can't use any of the addView methods of ListView in code like this:
listViewReference.addView(anotherView); // <-- don't do it
此外，如果您在 Activity 或适配器(其 getView 方法)的代码中使用了 LayoutInflater.inflate 方法，不要传递 ListView 作为第二个参数.例如，不要使用:
Also, if you use the LayoutInflater.inflate method in the code of the Activity or the adapter(its getView method), don't pass the ListView as the second parameter. For example, don't use:
convertView = inflator.inflate(R.layout.child_rows, parent);
在 Tamilarasi Sivaraj 的回答中，因为这将再次抛出异常.而是使用:
as in Tamilarasi Sivaraj's answer as that will throw the exception again. Instead use:
convertView = inflator.inflate(R.layout.child_rows, parent, false);
与您在问题中发布的异常相关，您似乎将 setText 方法与 int(s 或i 数组是一个 int 数组).问题在于，在这种情况下，TextView 会认为您正在尝试使用像这样的 R.string.astring 这样的字符串资源来设置文本.您传递的 int 不是字符串资源，因此将引发异常.如果 s 或 i 是 int 并且您尝试在 TextView 中显示它，请改用它:
Related to the exception you posted in the question, it appears you use the setText method with an int(one of the s or i arrays being an int array). The problem is that in this case TextView will think you're trying to set the text using a string resource like this R.string.astring. The int you pass is not a string resource so an exception will be thrown. If s or i is an int and you're trying to show it in the TextView use this instead:
tv.setText(String.valueOf(s[position])); // assuming s is the int array
