发送图片ID从片段到另一个活动

问题描述：

大家好我有一个问题，使用从片段意图发送图片ID到另一个活动，我搜索了有关问题，我看到了意图发送ID为双不int整理任何想法如何分享图片活动之间的ID。此问题与我的问题相同，但解决方案对我无效：How can i get Image Resource ID and send it to other activity in Android?。这里是我的程序发送图片ID从片段到另一个活动

public class BestTenPlaces extends Fragment { 

public BestTenPlaces() { 
    // Required empty public constructor 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    View rootView = inflater.inflate(R.layout.list, container, false); 
    final View detailsView = inflater.inflate(R.layout.details, container, false); 
    ArrayList<InfoObject> objects = new ArrayList<InfoObject>(); 
    objects.add(new InfoObject("baghdad 1", "gitnge", R.drawable.capture)); 
    objects.add(new InfoObject("string 2", "gitnge", R.drawable.capture)); 
    objects.add(new InfoObject("string 3", "gitnge", R.drawable.capture)); 
    objects.add(new InfoObject("string 4", "gitnge", R.drawable.capture)); 
    objects.add(new InfoObject("string 5", "gitnge", R.drawable.capture)); 
    objects.add(new InfoObject("string 6", "gitnge", R.drawable.capture)); 
    final ArrayList<InfoObject> details = new ArrayList<InfoObject>(); 
    details.add(new InfoObject("string 1", R.drawable.capture)); 
    details.add(new InfoObject("string 2", R.drawable.capture)); 
    details.add(new InfoObject("string 3", R.drawable.capture)); 
    details.add(new InfoObject("string 4", R.drawable.capture)); 
    details.add(new InfoObject("string 5", R.drawable.capture)); 
    details.add(new InfoObject("string 6", R.drawable.capture)); 
    GeneralAdapter BestPlaces = new GeneralAdapter(getActivity(),             objects); 
    ListView BestPlacesList = (ListView) rootView.findViewById(R.id.list); 
    BestPlacesList.setAdapter(BestPlaces); 
    BestPlacesList.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) { 
      InfoObject detailsArray = details.get(position); 
      String m = detailsArray.getmTextDetails(); 
      int s = (int) detailsArray.getImageResourcesObject(); 
      Intent intent = new Intent(getActivity(), details.class); 
      intent.putExtra("message", m); 
      intent.putExtra("resource", s); 
      startActivity(intent); 

     } 

    }); 
    return rootView; 
} 
}

，这里是活动

public class details extends AppCompatActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.details); 
    Bundle bundle = getIntent().getExtras(); 
    Bundle extra = getIntent().getExtras(); 
    int resources = extra.getInt("resource"); 
    String message = bundle.getString("message"); 
    TextView textDetails = (TextView) findViewById(R.id.text_details); 
    textDetails.setText(message); 
    ImageView imageDetails = (ImageView) findViewById(R.id.image_details); 
    imageDetails.setImageResource(resources); 
} 
}

这里的遍历infoObject

public class InfoObject { 
private String locationObject; 
private String placeNameObject; 
private int imageResourcesObject; 
private String mTextDetails; 
private int mDetailsImageResource; 

public InfoObject(String location, String placeName, int imageResources) { 
    locationObject = location; 
    placeNameObject = placeName; 
    imageResourcesObject = imageResources; 
} 

public InfoObject(String textDetails, int detailsImageResource) { 
    mTextDetails = textDetails; 
    mDetailsImageResource = detailsImageResource; 
} 

public String getmTextDetails() { 
    return mTextDetails; 
} 

public int getmDetailsImageResource() { 
    return mDetailsImageResource; 
} 

public String getLocationObject() { 
    return locationObject; 
} 

public String getPlaceNameObject() { 
    return placeNameObject; 
} 

public int getImageResourcesObject() { 
    return imageResourcesObject; 
} 

public void setLocationObject(String locationObject) { 
    this.locationObject = locationObject; 
} 

public void setPlaceNameObject(String placeNameObject) { 
    this.placeNameObject = placeNameObject; 
} 

public void setImageResourcesObject(int imageResourcesObject) { 
    this.imageResourcesObject = imageResourcesObject; 
} 
}

你是否在'details'活动中获得''message“'（'textDetails' TextView）？ –

是的我在“textDetails”TextView中得到的消息，但我没有得到图像Id –

请发布'InfoObject'的源代码。 –

答

当你填充阵列details在onCreateView方法，你使用的InfoObject下面的构造：

new InfoObject("string 3", R.drawable.capture)

此构造函数初始化场mDetailsImageResource NOT imageResourcesObject您稍后再试从读。

由于Java中未初始化int类成员将当您尝试从imageResourcesObject这是0阅读被自动初始化为0。

非常感谢你 –

答

简化您的方法，他们会更有效。例如，让我们传递消息。基本上，你会从一个片段发送一个字符串到一个新的活动。

在片段，请致电：

intent.putExtra("message", detailsArray.getmTextDetails());

然后在活动：

String message = getIntent().getStringExtra().getString("message");

答

使用此而不是详细活动

int resources = getIntent().getIntExtra("resource", 0); 
String message = getIntent().getString("message");

希望这将有助于。

答

您可以通过适当的方式做到这一点：

使有方法可以从片段调用一个接口。
在您的活动中实现此接口
从您的片段中创建接口的对象onAttach()给出活动上下文的方法。
借助于这个对象onActivityCreated()调用你的方法。
