Question

我有一个ListActivity从MYSQL得到一些数据，并插入他们的ListView里面......现在我有一个shareMethod，我需要接收该数据从的ListView分享..我很抱歉，但我想我已经把这里的整个活动..

“在此先感谢”

ListActivity.java

public class ListActivity extends AppCompatActivity implements 
AsyncResponse, AdapterView.OnItemClickListener { 


public static final int NOTIFICATION_ID = 1; 

final String LOG = "ListActivity"; 

private ArrayList<Product> productList; 
private ListView lvProduct; 
private FunDapter<Product> adapter; 

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

    ImageLoader.getInstance().init(UILConfig.config(ListActivity.this)); 

    PostResponseAsyncTask taskRead = new PostResponseAsyncTask(ListActivity.this, this); 

    //taskRead.execute("http://10.0.3.2/customer/product.php"); 
    taskRead.execute("http://symphonyrecords.6te.net/product.php"); 

    lvProduct = (ListView)findViewById(R.id.lvProduct); 

    registerForContextMenu(lvProduct); 


}//onCreate 


@Override 
public void processFinish(String s) { 
    productList = new JsonConverter<Product>().toArrayList(s, Product.class); 

    BindDictionary<Product> dict = new BindDictionary<Product>(); 
    dict.addStringField(R.id.tvName, new StringExtractor<Product>() { 
     @Override 
     public String getStringValue(Product product, int position) { 
      return product.name; 
     } 
    }); 

    dict.addStringField(R.id.tvDescription, new StringExtractor<Product>() { 
     @Override 
     public String getStringValue(Product product, int position) { 
      return product.description; 
     } 
    }); 


    dict.addStringField(R.id.tvDate, new StringExtractor<Product>() { 
     @Override 
     public String getStringValue(Product product, int position) { 
      return "" + product.date; 
     } 
    }); 


    dict.addStringField(R.id.tvQty, new StringExtractor<Product>() { 
     @Override 
     public String getStringValue(Product product, int position) { 
      return "" + product.qty; 
     } 
    }); 


    dict.addDynamicImageField(R.id.ivImage, 
      new StringExtractor<Product>() { 
       @Override 
       public String getStringValue(Product product, int position) { 
        return product.image_url; 
       } 
      }, new DynamicImageLoader() { 
       @Override 
       public void loadImage(String url, ImageView imageView) {    

        ImageLoader.getInstance().displayImage(url, imageView); 
        imageView.setPadding(0, 0, 0, 0); 
        imageView.setAdjustViewBounds(true); 
       } 
      }); 

    adapter = new FunDapter<>(
      ListActivity.this, productList, R.layout.layout_list, dict); 


    lvProduct.setAdapter(adapter); 
    lvProduct.setOnItemClickListener(this); 
} 

@Override 
public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
    Product selectedProduct = productList.get(position); 
    Intent in = new Intent(ListActivity.this, DetailActivity.class); 
    in.putExtra("product", (Serializable) selectedProduct); 
    startActivity(in); 


} 




//This is my share method 
public void shareMethod(View view1) 
{ 

    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); 
    sharingIntent.setType("text/plain"); 
    String shareBody = "Share content body"; 
    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here"); 
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT,shareBody); 
    startActivity(Intent.createChooser(sharingIntent, "share via")); 

} 



}

当单击列表中的项目，可以形成一个实例字符串变量，并从Product填写数据。在shareMethod中，您可以添加此字符串shareStr作为额外和共享。例如，

public class ListActivity..{ 
     private String mShareStr; 
      ... 
     < *When the list item is clicked fill in* 
    mShareStr = String.format("%s - %s for %s : %s", name, description, date, qty); > 

     public void shareMethod(View view1) 
     { 
      ... 
      sharingIntent.putExtra(Intent.EXTRA_TEXT, mShareStr); 
     } 
    }
