我收到这个错误
java.lang.IllegalArgumentException: Wrong state class, expecting View State but received class android.widget.AbsListView$SavedState instead. This usually happens when two views of different type have the same id in the same hierarchy. This view's id is id/unique111123234. Make sure other views do not use the same id.
当我在 View 寻呼机中切换选项卡时会发生此错误。我在下面使用自定义复合 View
public class RefreshableListView extends SwipeRefreshLayout {
private ListView listView;
private boolean disabled = false;
private Context context = null;
private AttributeSet attributes = null;
private RelativeLayout layout;
public RefreshableListView(Context context) {
super(context);
this.context = context;
initView();
}
public RefreshableListView(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
this.attributes = attrs;
initView();
}
private void initListView() {
listView = new ListView(context, attributes);
layout = new RelativeLayout(context);
this.addView(layout);
layout.addView(listView);
}
private void initView() {
initListView();
setColorScheme(android.R.color.holo_blue_bright,
android.R.color.holo_green_light,
android.R.color.holo_orange_light,
android.R.color.holo_red_light);
}
public void setAdapter(ListAdapter adapter) {
listView.setAdapter(adapter);
}
public void setOnItemClickListener(AdapterView.OnItemClickListener listener) {
listView.setOnItemClickListener(listener);
}
@Override
public boolean canChildScrollUp() {
boolean canScroll = listView.getFirstVisiblePosition() != 0;
if (disabled) {
canScroll = true;
}
return canScroll;
}
public Object getItemAtPosition(int position) {
return listView.getItemAtPosition(position);
}
public void setDisabled(boolean disable) {
disabled = disable;
}
public boolean isDisabled() {
return disabled;
}
public void setEmptyView(View emptyView) {
layout.addView(emptyView);
listView.setEmptyView(emptyView);
}
public void setSelection(int selection) {
listView.setSelection(selection);
}
public int getFirstVisiblePosition() {
return listView.getFirstVisiblePosition();
}
public Adapter getAdapter() {
return listView.getAdapter();
}
public int getCount() {
return listView.getCount();
}
}
我很困惑有没有人有煽动?
最佳答案
或者,您可以自己设置 Id 以避免冲突。当我以编程方式向我的自定义复合小部件添加 View 时,我遇到了完全相同的错误!
在您的情况下,解决方法是:
private void initListView() {
listView = new ListView(context, attributes);
layout = new RelativeLayout(context);
// Set Id's to ensure they are not the same
listView.setId(1000);
layout.setId(10001);
this.addView(layout);
layout.addView(listView);
}
我想当您从 XML 中扩充资源时,android 会为扩充的 View 分配一个随机 ID
