我对两个不同的项目布局使用相同的适配器。一个用于网格,一个用于线性显示。我将带有itemLayout的布局ID传递给适配器。但是,我无法正确添加数据绑定。你能帮帮我吗?
到目前为止,这是我的适配器工作:
public class OyuncuAdapter extends RecyclerView.Adapter<OyuncuAdapter.ViewHolder> {
ArrayList<Oyuncu> oyuncuListesi;
Context context;
int itemLayout;
public OyuncuAdapter(ArrayList<Oyuncu> oyuncuListesi, Context context, int itemLayout) {
this.oyuncuListesi = oyuncuListesi;
this.context=context;
this.itemLayout = itemLayout;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(itemLayout, parent, false);
return new ViewHolder(v);
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
Oyuncu oyuncu = oyuncuListesi.get(position);
holder.binding.setVariable(BR.oyuncu, oyuncu);
holder.binding.executePendingBindings();
}
@Override
public int getItemCount() {
return oyuncuListesi.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder{
private ViewDataBinding binding;
public ViewHolder(View itemView) {
super(itemView);
binding = DataBindingUtil.bind(itemView);
}
}
}
这是项目布局:
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto">
<data>
<variable
name="oyuncu"
type="com.figengungor.suits.model.Oyuncu" />
</data>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical"
android:padding="@dimen/itemPadding"
tools:background="@color/darkgrey">
<ImageView
android:id="@+id/foto"
android:layout_width="150dp"
android:layout_height="150dp"
android:gravity="center"
android:scaleType="centerCrop"
app:imageResource="@{oyuncu.foto}"
tools:src="@drawable/gabrielmacht" />
<TextView
android:id="@+id/isim"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="@android:color/white"
android:text="@{oyuncu.isim}"
tools:text="Gabriel Macht" />
</LinearLayout>
</layout>
我得到的错误并没有多大帮助:
Caused by: java.lang.RuntimeException: view tag isn't correct on view:null

我的坏。这部分很完美。我的问题是扩展BaseActivity,它也使用DataBinding。崩溃与此有关。从我的活动中删除扩展BaseActivity后,它工作正常。但是,我打开了另一个问题。如果你能看一下,我会感激不尽。 DataBinding: How to use BaseActivity
