Sugar ORM SQlite Android Part 2


Code Walkthrough :

      Previously you have seen how to use SugarORM with Android . In this , I will be giving you a walkthrough how the whole code works in an application, with a sample application which I have created. 

you can also download the complete android studio project from here

AndroidManifest.xml:

This is how the sample application will look like, when the application get installed, android will create an sqlite database named codexandroid.db as mentioned in this manifest. 

It will also assign the database version to be 1, if you add more table to your database you have to increement your database version number before deploying it on Google play store or for demo.

android:noHistory="true"  --> This is to stop android from keeping activity in stack , so that when you press back in this application, you won't be taken back to the previously used activity. 


    <application
        android:allowBackup="true"
        android:name="com.orm.SugarApp"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <meta-data android:name="DATABASE" android:value="codexandroid.db" />
        <meta-data android:name="VERSION" android:value="1" />
        <meta-data android:name="QUERY_LOG" android:value="true" />
        <meta-data android:name="DOMAIN_PACKAGE_NAME" android:value="com.hourglass.lingaraj.sugarormtuts.database" />

        <activity android:name=".Home">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".AddDataToTable" android:noHistory="true"/>
        <activity android:name=".ViewTableData" android:noHistory="true"/>
        <activity android:name=".UpdateTableData" android:noHistory="true"/>
        <activity android:name=".DeleteTableData" android:noHistory="true"/>

    </application>

UserTableSugar.java:

      A table name USER_TABLE_SUGAR will be created with the structure mentioned below.
     i. Member variable and methods must be static so that you can access it outside it's class scope. 
     ii. Empty Constructor is a must. 


public class UserTableSugar extends SugarRecord {

    public String name;
    public String profession;
    public boolean senior;

    public UserTableSugar()
    {

    }

   public UserTableSugar(String person_name,String profess,boolean value)
    {
        this.name = person_name;
        this.profession = profess;
        this.senior = value;
    }

}














AddDataToTable.java:



   In this class you will be adding new data to your table. I have commented inside code, so that you can understand easily, rather than explaining, it here. 








public class AddDataToTable extends AppCompatActivity {
    private Button submit,clear;
    private EditText name,profession,senior;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_data);
        initialDeclaration();
        submit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                /* If submit button is pressed, this listener will be triggered, and get Text from each fields and right it to database.
                 *
                 */
                String temp_name = name.getText().toString();
                String temp_profession = profession.getText().toString();
                String temp_senior = senior.getText().toString();
                boolean value;
                if (temp_senior.equals("true")) {
                    value = true;
                } else if (temp_senior.equals("false")) {
                    value = false;
                } else {
                    value = false;
                }
                //Passing data to Table using Constructor which we have Created  inside UserTableSugar.java
                UserTableSugar userTable = new UserTableSugar(temp_name, temp_profession, value);
                userTable.save();
                //calling save will write the data in UserTableSugar.java variable to SQLite Table
                clearAllFields();
                Toast.makeText(getApplicationContext(), "Data added to Table", Toast.LENGTH_SHORT).show();

            }
        });

        clear.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                clearAllFields();
            }
        });

    }

    private void clearAllFields() {

        name.setText("");
        profession.setText("");
        senior.setText("");
    }

    private void initialDeclaration() {
        name = (EditText) findViewById(R.id.name_edittext);
        profession = (EditText) findViewById(R.id.professsion_editText);
        senior = (EditText) findViewById(R.id.senior_editText);
        submit =(Button) findViewById(R.id.submit);
        clear = (Button) findViewById(R.id.clear);


    }
}














UpdateTableData.java:








public class UpdateTableData extends AppCompatActivity {

    EditText update_name,update_profession,update_senior,searchNameEditText;
    Button search,update;
    List<UserTableSugar> userTable;


    protected void onCreate(Bundle savedInstanceState) {

        update = (Button) findViewById(R.id.update);
        update_name = (EditText) findViewById(R.id.update_name);
        update_profession = (EditText) findViewById(R.id.update_profession);
        update_senior =  (EditText) findViewById(R.id.update_senior);

        /* Here we are searching by name from table, when you enter a name and press search , it will fetch the particular row,
         * and display in editText field, after changing the data you can save it with update code return below.
         */


        search.setOnClickListener(new View.OnClickListener() {
            @Override

                if(searchNameEditText.getText().toString().isEmpty())

 Adding Json array to Serializable Class using Gson. 




























       Why you should use Gson and Serializable Class to Handle Json Data:   Gson can be used along with Serializable class to save variables, unnecessary loops and memory  to save the data you get from Json.      Let's Imagine you have array of contact detail and its total count is four. which is something like this.
