Kumulos を使用して ListView を作成するのは非常に困難です。私の調査では、SQLite やその他のデータベースの使用に関する多数のチュートリアルや投稿を見つけましたが、Kumulos =/.
助けが必要なこと:
1) ListView を埋めるための Kumulos の実装
ソース: https://docs.kumulos.com/integration/android/
実施された研究:
Android で base64 文字列のビットマップ オブジェクトをエンコードおよびデコードする
Multicolumn ListView で HashMap を使用して DBHelper からデータを取得する方法
主な活動：
public class PersonSearchPop extends Activity {
private ListView personlist;
private CustomListViewAdapter customListViewAdapter;
public static final String YOUR_API_KEY = "HIDDEN";
public static final String YOUR_SECRET_KEY = "HIDDEN";
public static String encodeToBase64(Bitmap image, Bitmap.CompressFormat compressFormat, int quality)
{
ByteArrayOutputStream byteArrayOS = new ByteArrayOutputStream();
image.compress(compressFormat, quality, byteArrayOS);
return Base64.encodeToString(byteArrayOS.toByteArray(), Base64.DEFAULT);
}
public static Bitmap decodeBase64(String input)
{
byte[] decodedBytes = Base64.decode(input, 0);
return BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.length);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listview_popup);
Kumulos.initWithAPIKeyAndSecretKey(YOUR_API_KEY, YOUR_SECRET_KEY, this);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels;
int height = dm.heightPixels;
getWindow().setLayout((int) (width * .4), (int) (height * .6));
?????????????????????????????????????????????????????????????????????????????????
personlist.setOnItemClickListener(new AdapterView.OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
finish();
}
});
}
}
カスタムアダプター:
public class CustomListViewAdapter extends CursorAdapter {
public CustomListViewAdapter(Context context, Cursor c){
super (context, c);
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View retView = inflater.inflate(R.layout.personlist_row, parent, false);
return retView;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
TextView dl = (TextView) view.findViewById(R.id.tvdl);
dl.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(7))));
TextView last = (TextView) view.findViewById(R.id.tvLastName);
last.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(1))));
TextView first = (TextView) view.findViewById(R.id.tvFirstName);
first.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(3))));
TextView middle = (TextView) view.findViewById(R.id.tvMiddleName);
middle.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(2))));
TextView ss = (TextView) view.findViewById(R.id.tvSS);
ss.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(8))));
//ImageView image = (ImageView) view.findViewById(R.id.idPic);
//image.setImageDrawable(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(12))));
}
}
データを入力してください:
public class EnterData extends Activity {
EditText lName;
EditText dl;
EditText ss;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.persons_popup);
lName = (EditText) findViewById(R.id.etLastName);
dl = (EditText) findViewById(R.id.etDL);
ss = (EditText) findViewById(R.id.etSocial);
}
public void onClickSearch (View btnSearch) {
String personName = lName.getText().toString();
String personDL = dl.getText().toString();
String personSS = ss.getText().toString();
}
}
}
更新: わかりました、コードを 2 つのクラスだけに変更しましたが、動作しているようです。ただし、Kumulos からエラーが発生しています =/.
