View.OnClickListener无效

Question

我的View.OnClickListener中有Recycler View，但每当我点击一个视图时，它都不会触发onClick事件

以下是代码：

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
    TextView name;
    ImageView image;
    Context context;
    ArrayList<Categories_Model_Class> arrayList;

    public ViewHolder(View view, Context context, ArrayList<Categories_Model_Class> arrayList) {
        super(view);
        name = view.findViewById(R.id.category_name);
        image = view.findViewById(R.id.category_image);
        this.context = context;
        this.arrayList = arrayList;
        view.setOnClickListener(this);
        Log.i("Created", "ViewHolder");
    }

    @Override
    public void onClick(View view) {
        //Pair<View, String> pair1 = Pair.create((View) this.image, this.image.getTransitionName());
        Intent intent = new Intent(context, FullWallpaperViewActivity.class);
        //ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation((Activity)context, pair1);
        context.startActivity(intent);
        Log.i("TOUCH", "TOUCH");
    }
}

任何建议？

• CardView模型类的布局

  <?xml version="1.0" encoding="utf-8"?>

  </FrameLayout>
  </LinearLayout>
  

Answer 1

顶部布局（<LinearLayout>中的view视图（在代码中作为android:clickable访问）正在自行处理点击事件。

您需要从<FrameLayout>中移除<FrameLayout android:layout_width="match_parent" android:layout_height="150dp" android:layout_margin="4dp" android:focusable="true" android:foreground="?attr/selectableItemBackground"> ，如此：

< LinearLayout>

如果没有，它将消耗点击，不会到达父var options = new ParallelOptions { MaxDegreeOfParallelism = 4 }; Parallel.ForEach(items, options, t => { try { var result = DoWork(t.A, t.Range).Result; } catch (Exception ex) { _logger.LogError(ex, $"{ex.ToString()}"); } }); public async Task<string> DoWork(A table, SqlXml range) { _context.Database.SetCommandTimeout(150000); using (var cmd = Conn.CreateCommand()) { cmd.CommandTimeout = 1200; cmd.CommandText = "storedProc"; cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new SqlParameter("@id", SqlDbType.SmallInt) { Value = table.Id }); cmd.Parameters.Add(new SqlParameter("@Range", SqlDbType.Xml) { Value = range }); var result = await cmd.ExecuteScalarAsync(); return result as string; } } 。

Answer 2

view.setClickable(true);
view.setOnClickListener(this);
