每次用户点击popup menu右下角的button时，我都会尝试显示card，但每次点击此{{1}我收到此错误：
android.view.InflateException：二进制XML文件行＃0：无法解析索引6处的属性：TypedValue {t = 0x3 / d = 0x6db“res / drawable-xxhdpi-v4 / ic_dots.png”a = 4 r = 0x7f080080}
我认为错误可能是因为我将错误的图标放在错误的文件夹中，所以我尝试将所有图标放在正确的可绘制文件夹中，例如button，drawable-hdpi，{{1} }，drawable-xxhdpi drawable-mdpi drawable-xxxhdpi drawable-xhdpi logcat`，代码如下：
logcat的

表示错误位于方法public class CourseAdapter extends RecyclerView.Adapter<CourseAdapter.MyViewHolder> {
private Context mContext;
private List<Courses> coursesList;
public CourseAdapter(Context mContext, List<Courses> coursesList) {
this.mContext = mContext;
this.coursesList = coursesList;
}
@Override
public CourseAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.courses_list, parent, false);
return new MyViewHolder(itemView);
}
@Override
public void onBindViewHolder(final CourseAdapter.MyViewHolder holder, int position) {
Courses album = coursesList.get(position);
holder.title.setText(album.getName());
holder.subtext.setText(album.getSubtext());
// loading album cover using Glide library
Glide.with(mContext).load(album.getThumbnail()).into(holder.thumbnail);
holder.overflow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
showPopupMenu(holder.overflow);
}
});
}
/**
* Showing popup menu when tapping on 3 dots
*/
private void showPopupMenu(View view) {
// inflate menu
PopupMenu popup = new PopupMenu(mContext, view);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.menu_course, popup.getMenu());
popup.setOnMenuItemClickListener(new MyMenuItemClickListener());
popup.show();
}
/**
* Click listener for popup menu items
*/
class MyMenuItemClickListener implements PopupMenu.OnMenuItemClickListener {
public MyMenuItemClickListener() {
}
@Override
public boolean onMenuItemClick(MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.action_apply:
Toast.makeText(mContext, "Apply", Toast.LENGTH_SHORT).show();
return true;
default:
}
return false;
}
}
@Override
public int getItemCount() {
return coursesList.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title, subtext;
public ImageView thumbnail, overflow;
public MyViewHolder(View view) {
super(view);
title = (TextView) view.findViewById(R.id.title);
subtext = (TextView) view.findViewById(R.id.subtext);
thumbnail = (ImageView) view.findViewById(R.id.thumbnail);
overflow = (ImageView) view.findViewById(R.id.overflow);
}
}
}
logcat的{{1}}文件如下：
menu_course
showPopupMenu(View view)有人可以帮忙吗？
答案 0 :(得分：0)
尝试使用 -
mContext.getMenuInflater();
而不是
popup.getMenuInflater();
