android - SimpleCursorAdapter をサブクラス化して、メモリ節約のために convertView を含める

Question

私は例とチュートリアルを精査してきましたが、サブクラス化された SimpleCursorAdapter 内でリサイクルを処理する方法について理解できないようです。通常の ArrayAdapter では、convertView で null をチェックし、null の場合は xml からインフレートし、null でない場合はリサイクルできることを知っていますが、SimpleCursorAdapter サブクラス内の from 配列と to 配列でそれがどのように機能するかを視覚化するのに少し問題があります。Commonsware の The Busy Coders Guide to Android Development からこれを理解しようとしましたが、うまくいきませんでした。誰かがヒント、例、またはチュートリアルを知っている場合は、それらを見て感謝します.

Answer 1

SimpleCursorAdapter をサブクラス化して convertView リサイクル方法論を使用するための良い例を見つけることができなかったため、代わりに CursorAdapter をサブクラス化することになりました。これは実際に私の実装では非常にうまく機能し、メモリ使用量が劇的に減少して非常に高速です。ビューのリサイクルは本当に機能するので、強くお勧めします!

これが私の実装の例です：

 private static class MyNiftyAdapter extends CursorAdapter
    {
        private LayoutInflater mInflater;
        private Cursor cur;

        public MyNiftyAdapter(Context context, Cursor c) {
            super(context,c);       
            this.mInflater = LayoutInflater.from(context);
            this.cur = c;
        }
        public MyNiftyAdapter(Context context, Cursor c, boolean autoRequery)
        {
            super(context, c, autoRequery);
            this.mInflater = LayoutInflater.from(context);
            this.cur = c;
        }
        @Override
        public View getView(int position, View convertView, ViewGroup parent)
        {
            ViewHolder viewHolder;
            if(convertView == null)
            {
                convertView = this.mInflater.inflate(R.layout.chamber_item, null);
                viewHolder = new ViewHolder();
                viewHolder.name = (TextView)convertView.findViewById(R.id.Name);
                viewHolder.city = (TextView)convertView.findViewById(R.id.city);
                viewHolder.state = (TextView)convertView.findViewById(R.id.state);
                viewHolder.country = (TextView)convertView.findViewById(R.id.country);
                convertView.setTag(viewHolder);
            }else
            {
                viewHolder = (ViewHolder)convertView.getTag();
            }
            this.cur.moveToPosition(position);

            viewHolder.name.setText(this.cur.getString(this.cur.getColumnIndex(MyDBHelper.NAME)));          
            viewHolder.city.setText(this.cur.getString(this.cur.getColumnIndex(MyDBHelper.CITY)));
            viewHolder.state.setText(this.cur.getString(this.cur.getColumnIndex(MyDBHelper.STATE)));
            viewHolder.country.setText(this.cur.getString(this.cur.getColumnIndex(MyDBHelper.COUNTRY)));            

            return convertView;
        }
        /* (non-Javadoc)
         * @see android.widget.CursorAdapter#bindView(android.view.View, android.content.Context, android.database.Cursor)
         */
        @Override
        public void bindView(View view, Context context, Cursor cursor) {
            // Dont need to do anything here

        }
        /* (non-Javadoc)
         * @see android.widget.CursorAdapter#newView(android.content.Context, android.database.Cursor, android.view.ViewGroup)
         */
        @Override
        public View newView(Context context, Cursor cursor, ViewGroup parent) {
            // Dont need to do anything here either
            return null;
        }

        static class ViewHolder
        {
            TextView name;
            TextView city;
            TextView state;
            TextView country;
        }
    }

リストの各行には、希望どおりに名前、都市、州、国が表示されるようになりました。お役に立てれば。

Answer 2

CursorAdapter は部分的に作業を行います。新しいビューを作成する必要がある場合は newView() をオーバーライドするだけでよく、既存のビューを再利用する場合は bindView() をオーバーライドする必要があります。

Answer 3

import java.util.ArrayList;

import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CursorAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class AccountsAdapter extends CursorAdapter {

 public static final String TAG = AccountsAdapter.class.getSimpleName();

 private Boolean DEBUG=true;
 private LayoutInflater mInflater;
 private int layoutResource;
 private Cursor mCursor;
 private int acctInd;
 private int upicInd;
 private  ViewHolder holder;
 public AccountsAdapter(Context context,Cursor c,int resourceId) {
     super(context,c);
     this.mCursor=c;
     acctInd=mCursor.getColumnIndex(LJDB.KEY_JOURNALNAME);
     upicInd=mCursor.getColumnIndex(LJDB.KEY_DEFAULTUSERPIC);

     this.layoutResource=resourceId;
     this.mInflater = LayoutInflater.from(context);
 }


 private static class ViewHolder {
     ImageView userpic;
     TextView journalname;
 }


@Override
  public void bindView(View view, Context context, Cursor cursor) {
       holder = (ViewHolder) view.getTag();
            holder.journalname.setText(cursor.getString(acctInd));
            holder.userpic.setTag(cursor.getString(upicInd));

}
  @Override
  public View newView(Context context, Cursor cursor, ViewGroup parent) {
     View v = mInflater.inflate(layoutResource, null);
             holder = new ViewHolder();
             holder.userpic = (ImageView) v.findViewById(R.id.duserpic);
             holder.journalname = (TextView) v.findViewById(R.id.uname);

         v.setTag(holder);
         return v;

}}

Answer 4

ResourceCursorAdapterをサブクラス化することもできます。その場合、bindviewメソッドをオーバーライドするだけで済みます。

public class MySimpleCursorAdapter extends ResourceCursorAdapter {

public MySimpleCursorAdapter(Context context, Cursor c) {
    super(context, R.layout.myLayout, c);
}

@Override
public void bindView(View view, Context context, Cursor cursor) {
    ViewHolder viewHolder = (ViewHolder) view.getTag();
    if (viewHolder == null) {
        viewHolder = new ViewHolder(view);
        view.setTag(viewHolder);
    }
    viewHolder.bind(cursor, context);
}

/**
 * A ViewHolder keeps references to children views to avoid unnecessary calls
 * to findViewById() on each row (especially during scrolling)
 */
private static class ViewHolder {
    private TextView text;

    private ToggleButton toggle;

    public ViewHolder(View view) {
        text = (TextView) view.findViewById(R.id.rowText);
        toggle = (ToggleButton) view.findViewById(R.id.rowToggleButton);
    }

    /**
     * Bind the data from the cursor to the proper views that are hold in
     * this holder
     * @param cursor
     */
    public void bind(Cursor cursor, Context context) {
        toggle.setChecked(0 != cursor.getInt(cursor.getColumnIndex("ENABLED")));
        text.setText(cursor.getString(cursor.getColumnIndex("TEXT")));
    }
}

}

Answer 5

私のテストに基づくと、受け入れられた回答は正しくないようです (さらに、不必要です)。

（単純なLog.e出力テストに基づいて）私が知る限り、ビューのリサイクルはデフォルトで正しく処理されます（@Romain Guyが述べたように）。これは、私が遭遇したドキュメントでgetView()をオーバーライドする必要があるという推奨事項がないことを正当化すると思います。

これは、私がこの結論に達するために使用した単純な例で使用されたコード スニペットです。

public class MediaAdapter extends CursorAdapter {

    @Override
    public void bindView(View arg0, Context arg1, Cursor arg2) {
        Log.e("bindView", "Called: " + arg2.getPosition());
        ImageView iv = (ImageView) arg0;
        iv.setImageDrawable(new BitmapDrawable(getResources(), MediaStore.Images.Thumbnails.getThumbnail(arg1.getContentResolver(), 
                arg2.getInt(arg2.getColumnIndex(MediaStore.Images.Media._ID)), MediaStore.Images.Thumbnails.MICRO_KIND, null)));

    }

    @Override
    public View newView(Context arg0, Cursor arg1, ViewGroup arg2) {
        Log.e("newView", "Called: " + arg1.getPosition());
        ImageView iv = new ImageView(ctFrag);
        iv.setLayoutParams(new AbsListView.LayoutParams(LayoutParams.WRAP_CONTENT, 96));
        iv.setPadding(Spine.getDp(2), Spine.getDp(2), Spine.getDp(2), Spine.getDp(2));

        return iv;
    }

}

これを GridView で使用して、使用可能な画像サムネイルのグリッドを表示すると、LogCat 出力は次のようになりました。

これは、ビューがnewView()の呼び出しによって作成されると、bindView()がビューの変換を処理してメモリを最適化することを非常に明確に示しているようです。

(途中でnewView()が呼び出される数行は、行全体ではなく行の 2 つの部分を表示するときに新しい行を必要とするGridViewです)。
