RecyclerView内のEditTextのフォーカスを取得

Question

私は、デビットカードを保存できるアプリケーションを実装しています。後で同じカードのCVV番号を入力するだけで使用できます。私はRecyclerViewをユーザーが保管したすべてのアイテム（デビットカード）に使用しました。すべてがうまくいき、ビューがすべてレンダリングされ、LinearLayoutManagerを使って水平スクロールを表示しています。

今私が直面している問題は、私がそれをクリックするとすぐにCVVを入力しようとすると、ビューは保存カードのリストの最後のアイテムに向かって移動します。カードは私のリストに格納されていて、CVVを最初に入力しようとすると、ビューは第3のカードに直接シフトしますが、フォーカスは最初のカードのEditTextに残ります。私は同じことが何に起こっているのか分かりません。私は同じもののためにいくつかのコード部分を共有しています。

アダプタを設定し、水平スクロールを定義： -

recyclerAdapter = new RecyclerStoredCardAdapter(mContext, storedCards); 
       LinearLayoutManager layoutManager 
         = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false); 
       storedCardListRecycler.setLayoutManager(layoutManager); 
       storedCardListRecycler.setVisibility(View.VISIBLE); 
       storedCardListRecycler.setAdapter(recyclerAdapter); 

それを明確になりますので、これでスクリーンショットを共有します。どんな助けにも感謝します。ありがとう。

私はRecyclerView

とListViewないを使用してこれをしなかったしている。しかし、あなたはまた、RecyclerViewで行うことができます。

私の使用したクラスのデモです。

私はあなたに私のクラス全体を与えています。どうして？これは、私がListViewでどのように使用したかをより深く理解するためです。

テストして教えてください。 :)

注

• このコード行は非常に重要である - この問題を再現することができgetActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_MASK_ADJUST);

Answer 2

ありません。次のコードがあなたが直面していることをしているかどうかを教えてください。そうでない場合は、アダプタのコードを共有すると、より多くのフィードバックを提供することができます。

MainActivity.java 
public class MainActivity 
    extends AppCompatActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view); 
    MyAdapter adapter = new MyAdapter(); 
    recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)); 
    recyclerView.setAdapter(adapter); 
} 
} 


public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> { 

@Override 
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_ite, parent); 
    return new MyViewHolder(view); 
} 

@Override 
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 
    ((EditText)((MyViewHolder)holder).mBinding.findViewById(R.id.editText)).setHint(position + " "); 
} 

@Override 
public int getItemCount() { 
    return 100; 
} 

public class MyViewHolder extends RecyclerView.ViewHolder { 
    View mBinding; 
    public MyViewHolder(View binding) { 
     super(binding); 
     this.mBinding = binding; 
    } 
} 
} 

the 2xml layouts. 
<android.support.v7.widget.CardView 
android:id="@+id/card_view" 
android:layout_height="wrap_content" 
android:layout_width="wrap_content" 
xmlns:android="http://schemas.android.com/apk/res/android"> 

<EditText 
    android:id="@+id/editText" 
    android:layout_height="200dp" 
    android:layout_width="300dp"/> 

</android.support.v7.widget.CardView> 

マイmain_activity.xml次のとおりです。

<RelativeLayout 
android:layout_height="match_parent" 
android:layout_width="match_parent" 
xmlns:android="http://schemas.android.com/apk/res/android"> 

<android.support.v7.widget.RecyclerView 
    android:id="@+id/recycler_view" 
    android:layout_height="wrap_content" 
    android:layout_width="match_parent"/> 
</RelativeLayout> 

あなたは、これが最も単純なケースで見ることができるように。もし私が何かを見逃したら教えてください。
