どのように私は2つの活性を有する

Question

dinamically 2つの活動を使用してリストビューとカスタムアダプタにギャラリーから画像やカメラで撮影を追加しますタイトルのTextView、ListView - 私のスタンプのリストとFloatingButtonActionを表示します。

私がFloatingButtonActionをクリックすると、私が話している2番目のアクティビティ、InsertStampActivityを開始したいと思います。

第二活性

：InsertStampActivity

I 3のEditText（挿入国、値、年間）のImageButton及び（挿入されたイメージのために）空のImageViewのを有するInsertStampActivity 。 ImageButtonをクリックすると、Button - FROM GALLERY、Button - TAKE PHOTOまたはButton - EXITの3つのボタンでAlertDialogBoxがポップアップします。

FROM GALLERYをクリックすると、写真を撮るために写真を撮るために写真をクリックし、写真を撮るために写真をクリックし、EXITをクリックしてMyCollectionActivityに戻るために、電話のギャラリーから写真を選択します。

私はCustomAdapterを使用したいと思います。

--- 私の問題は、挿入されたイメージを管理する方法です。 ---

私のクラスTimbru（スタンプを意味する）：

public class Timbru implements Parcelable { 

private Integer year; 
private String country; 
private Float value; 
private String imagePath; 

public Timbru(int year, String country, float value, String imagePath) { 
    this.year = year; 
    this.country = country; 
    this.value = value; 
    this.imagePath = imagePath; 
} 

public Timbru() { 
} 

public String getImagePath() { 
    return imagePath; 
} 

public void setImagePath(String imagePath) { 
    this.imagePath = imagePath; 
} 

public Integer getYear() { 
    return year; 
} 

public void setYear(Integer year) { 
    this.year = year; 
} 

public String getCountry() { 
    return country; 
} 

public void setCountry(String country) { 
    this.country = country; 
} 

public Float getValue() { 
    return value; 
} 

public void setValue(Float value) { 
    this.value = value; 
} 

@Override 
public String toString() { 
    return "Timbru{" + 
      "year=" + year + 
      ", country='" + country + '\'' + 
      ", value=" + value + 
      ", imagePath='" + imagePath + '\'' + 
      '}'; 
} 

public Timbru(Parcel in) { 
    this.year = in.readInt(); 
    this.country = in.readString(); 
    this.value = in.readFloat(); 
} 

public static Parcelable.Creator<Timbru> CREATOR = new Creator<Timbru>() { 
    @Override 
    public Timbru createFromParcel(Parcel parcel) { 
     return new Timbru(parcel); 
    } 

    @Override 
    public Timbru[] newArray(int i) { 
     return new Timbru[i]; 
    } 
}; 

@Override 
public int describeContents() { 
    return 0; 
} 

@Override 
public void writeToParcel(Parcel parcel, int i) { 
    parcel.writeInt(year); 
    parcel.writeString(country); 
    parcel.writeFloat(value); 
    } 
} 

これはリストを維持するためのクラスです：

public class ListaTimbru { 

private static ArrayList<Timbru> timbre = new ArrayList<>(); 

public static ArrayList<Timbru> getTimbre() { 
    return timbre; 
} 

public ListaTimbru() { 

    } 
} 

これはTimbruAdapterクラスです：

public class TimbruAdapter extends ArrayAdapter { 

private int resource; 
private List<Timbru> objects; 
private LayoutInflater inflater; 


public TimbruAdapter(@NonNull Context context, @LayoutRes int resource, @NonNull List objects, LayoutInflater inflater) { 
    super(context, resource, objects); 
    this.inflater = inflater; 
    this.resource = resource; 
    this.objects = objects; 
} 

@NonNull 
@Override 
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) { 

    View row = inflater.inflate(this.resource, parent, false); 

    TextView tvYear = (TextView) row.findViewById(R.id.tv_year_rowLayout2); 
    TextView tvCountry = (TextView) row.findViewById(R.id.tv_country_rowLayout2); 
    TextView tvValue = (TextView) row.findViewById(R.id.tv_value_rowLayout2); 

    Timbru timbru = objects.get(position); 

    tvCountry.setText(timbru != null && timbru.getCountry() != null ? timbru.getCountry() : ""); 
    tvYear.setText(timbru != null && timbru.getYear() != null ? timbru.getYear().toString() : ""); 
    tvValue.setText(timbru != null && timbru.getValue() != null ? timbru.getValue().toString() : ""); 

    return row; 
    } 
} 

これはMyCollectionActivityです：

public class MyColectionActivity extends AppCompatActivity { 

    FloatingActionButton fltBtn_insert; 
    ListView listViewStamps; 
    List<String> listStamps = new ArrayList<>(); 
    List<Timbru> listStamps2 = new ArrayList<>(); 

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

    fltBtn_insert = (FloatingActionButton) 
    findViewById(R.id.flBtn_insertNewStamp_myCollection); 
    listViewStamps = (ListView) 
    findViewById(R.id.lv_stampList_myCollection); 

    TimbruAdapter adapter = new TimbruAdapter(getApplicationContext(), R.layout.row_layout2, ListaTimbru.getTimbre(), getLayoutInflater()); 
    listViewStamps.setAdapter(adapter); 

    fltBtn_insert.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent intent = new Intent(getApplicationContext(), InsertStampActivity.class); 
      startActivityForResult(intent, Constants.ADD_STAMP_REQUEST_CODE); 
     } 
    }); 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == Constants.ADD_STAMP_REQUEST_CODE && resultCode == RESULT_OK && data != null) { 
     Timbru result = data.getParcelableExtra(Constants.ADD_STAMP_KEY); 
     if (result != null) { 
      ListaTimbru.getTimbre().add(result); 
      TimbruAdapter currentAdapter = (TimbruAdapter) listViewStamps.getAdapter(); 
      currentAdapter.notifyDataSetChanged(); 
     } 
    } 
} 

これはInsertStampActivityです：

Answer 1

同じ活動（InsertStampActivity）ではあなたは、アダプタクラスビューの追加に続いてImageViewの

case REQUEST_IMAGE_TAKEN: 
if (requestCode == REQUEST_IMAGE_TAKEN && resultCode == RESULT_OK) 
{ 
    Bitmap photo = (Bitmap) data.getExtras().get("data"); 
    poza_timbru.setImageBitmap(photo); //poza_timbru is your imageview. 
} 
case PICK_IMAGE_REQUEST: 
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) 
{ 

    Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath)); 
    poza_timbru.setImageBitmap(thumbnail); //poza_timbru is your imageview. 
} 

にカメラ&ギャラリーから画像を表示するには、このコードを使用することができますR.Layout.row_layout2の1つのイメージビューは、データをアダプタクラスに渡して、それをlistviewに表示します。

希望することができます..！
