Question

我想动态更改textviews的高度以适合其他linearlayout中的单元格。

我试图通过这种方式做到这一点：

    @Override
    public void onBindViewHolder(@NonNull final MyViewHolder holder, final int position) {



         holder.numberCage.setText(cages.get(position).getNumberCage());
         holder.eggsDescription.setText(cages.get(position).getEggsDescription());
         holder.eggsFrom.setText(cages.get(position).getNumberCageFrom());

         if(cages.get(position).getBasicEggs().toString().equals("true"))
         holder.basicEggs.setText("Tak");
         else
             holder.basicEggs.setText("Nie");

         holder.dateEggs.setText(cages.get(position).getDateEggs());

         holder.description.setText(cages.get(position).getDescription());
         holder.pigeonsInside.setText(cages.get(position).getPigeonsInside());


         holder.numberCageTitle.setHeight(holder.numberCage.getHeight());
         holder.eggsDescriptionTitle.setHeight(holder.eggsDescription.getHeight());
         holder.eggsFromTitle.setHeight(holder.eggsFrom.getHeight());
         holder.basicEggsTitle.setHeight(holder.basicEggs.getHeight());
         holder.dateEggsTitle.setHeight(holder.dateEggs.getHeight());
         holder.descriptionTitle.setHeight(holder.description.getHeight());
         holder.pigeonsInsideTitle.setHeight(holder.pigeonsInside.getHeight());
    }
    class MyViewHolder extends RecyclerView.ViewHolder{
         TextView numberCage,pigeonsInside,description, dateEggs, basicEggs, eggsFrom, eggsDescription, numberCageTitle, pigeonsInsideTitle, descriptionTitle, dateEggsTitle, basicEggsTitle, eggsFromTitle, eggsDescriptionTitle;
         LinearLayout linearLayout, linearLayoutLeft, linearLayoutRight;
         public MyViewHolder(View view){
             super(view);
             numberCage = view.findViewById(R.id.numberCage);
             pigeonsInside = view.findViewById(R.id.pigeonsInside);
             description = view.findViewById(R.id.description);
             dateEggs = view.findViewById(R.id.dateEggs);
             basicEggs = view.findViewById(R.id.basicEggs);
             eggsFrom = view.findViewById(R.id.eggsFrom);
             eggsDescription = view.findViewById(R.id.eggsDescription);


             numberCageTitle = view.findViewById(R.id.numberCageTitle);
             pigeonsInsideTitle = view.findViewById(R.id.pigeonsInsideTitle);
             descriptionTitle = view.findViewById(R.id.descriptionTitle);
             dateEggsTitle = view.findViewById(R.id.dateEggsTitle);
             basicEggsTitle = view.findViewById(R.id.basicEggsTitle);
             eggsFromTitle = view.findViewById(R.id.eggsFromTitle);
             eggsDescriptionTitle = view.findViewById(R.id.eggsDescriptionTitle);


            linearLayout = view.findViewById(R.id.linearLayout);
         }
    }

我有很好的结果，但是我的问题是我必须向下滚动并向上滚动列表才能“加载”这个高度，我不知道该如何告诉我，所以我向您展示了屏幕截图。

Answer 1

创建另一个名为sub_layout.xml的文件，该文件将具有以下代码：-

 <LinearLayout
        android:id="@+id/linear"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:weightSum="1"
        android:orientation="horizontal">
        <TextView
            android:id="@+id/txtTitleStatic"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.45"
            android:text="Jajka przełożone skąd? (klatka)"
            android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

        <TextView
            android:id="@+id/txtTitle"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight=".55" />
    </LinearLayout>

，然后使用以下代码将其包含在主布局中（您的内容XML文件）：-

<include
        android:id="@+id/numberCageLayout"
        layout="@layout/sub_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />


<include
        android:id="@+id/pigeonsInsideLayout"
        layout="@layout/sub_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

<include
        android:id="@+id/descriptionLayout"
        layout="@layout/sub_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

现在，在Java文件中，其定义如下：-

View numberCageLayout =  findViewById(R.id.numberCageLayout);
View pigeonsInsideLayout =  findViewById(R.id.pigeonsInsideLayout);
View descriptionLayout =  findViewById(R.id.descriptionLayout);

TextView numberCageStatic =numberCageLayout.findViewById(R.id.txtTitleStatic);
TextView numberCage =numberCageLayout.findViewById(R.id.txtTitle);


TextView pigeonsInsideStatic =pigeonsInsideLayout.findViewById(R.id.txtTitleStatic);
TextView pigeonsInside =pigeonsInsideLayout.findViewById(R.id.txtTitle);

现在像这样，您不必担心单元格的高度。
