从 Azure 检索数据

Question

I created an azure account connected it with a current android application, created a table and added data to this table from within my application. The text is added into a textbox and one the button is clicked the data is sent to Azure. I want to be able to retrieve this data in the "Text" field in a list. Could anyone show me how I would do this.

My Code is as fallows

MainActivity

public class MainActivity extends AppCompatActivity {
    private MobileServiceClient mClient;
    private EditText title;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        try {
            mClient = new MobileServiceClient(
                    "https://craigsapp.azure-mobile.net/",
                    "BTkcgnFQvevAdmmRteHCmhHPzdGydq84",
                    this
            );
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }

    }

    public void onClickB(View view) {

title= (EditText) findViewById(R.id.editText);

        Item item = new Item();
        item.Text = title.getText().toString();

        mClient.getTable(Item.class).insert(item, new TableOperationCallback<Item>() {
            public void onCompleted(Item entity, Exception exception, ServiceFilterResponse response) {
                if (exception == null) {
                    // Insert succeeded
                } else {
                    // Insert failed
                }
            }
        });
    }

}

Item Activity

public class Item {
    public String Id;
    public String Text;

}

Answer 1

For the POJO Class file Item.java .

public class Item {
    @com.google.gson.annotations.SerializedName("id")
    private String id;

    @com.google.gson.annotations.SerializedName("text")
    private String text;

    public Item() {}
    public Item(String id, String text) {
        this.id = id;
        this.text = text
    }

    // The getter and setter functions for echo property, and the functions `toString` and `equals`
    ......
}

As reference, there is a similiar sample project GetStartedWithData , please see https://github.com/Azure/mobile-services-samples/tree/master/GettingStartedWithData/Android/GetStartedWithData/src/com/example/GetStartedWithData .

For inserting data into mobile service, please refer to the section How to: Insert data into a mobile service .

To retrieve your data from azure sql database you have to do it through an asynctask or android service and then use a broadcast receiver to get it to a text field. If you still need help comment below.
