android - AdapterView 不支持无法启动 Activity :UnsupportedOperationException: addView(View, LayoutParams)

Question

我想写一个基本格式的 ListView 但我得到一个错误:

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做一些事情:

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;

}

我应该怎么做才能解决问题

Answer 1

what should i do???

更正您的代码。

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

AdapterView 的子类，例如 ListView 不能 在布局文件中手动添加子类或在代码中添加子类。因此，如果您在其中一种布局中有此功能:

<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:

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

您也不能在如下代码中使用 ListView 的任何 addView 方法:

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

另外，如果你在Activity或适配器(它的getView方法)的代码中使用LayoutInflater.inflate方法，< strong>不要传递 ListView 作为第二个参数。例如，不要使用:

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

在 Tamilarasi Sivaraj 的回答中，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有关，您似乎将 setText 方法与 int(s 之一或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 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 并且您试图在 TextView 中显示它，请改用:

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