How to filter data using where Clause and “AND” in Android sqlite?

Before getting into example, we should know what sqlite data base in android is. SQLite is an open source SQL database that stores data to a text file on a device. Android comes in with built in SQLite database implementation. SQLite supports all the relational database features. In order to access this database, you don't need to establish any kind of connections for it like JDBC, ODBC etc.
This example demonstrates How to filter data using where Clause and “AND” in Android sqlite.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
   xmlns:tools = "http://schemas.android.com/tools"
   android:layout_width = "match_parent"
   android:layout_height = "match_parent"
   tools:context = ".MainActivity"
   android:orientation = "vertical">
   <EditText
      android:id = "@+id/name"
      android:layout_width = "match_parent"
      android:hint = "Enter Name"
      android:layout_height = "wrap_content" />
   <EditText
      android:id = "@+id/salary"
      android:layout_width = "match_parent"
      android:inputType = "numberDecimal"
      android:hint = "Enter Salary"
      android:layout_height = "wrap_content" />
   <LinearLayout
      android:layout_width = "wrap_content"
      android:layout_height = "wrap_content"><Button
      android:id = "@+id/save"
      android:text = "Save"
      android:layout_width = "wrap_content"
      android:layout_height = "wrap_content" />
   <Button
      android:id = "@+id/refresh"
      android:text = "Refresh"
      android:layout_width = "wrap_content"
      android:layout_height = "wrap_content" />
   <ListView
      android:id = "@+id/listView"
      android:layout_width = "match_parent"
      android:layout_height = "wrap_content">
   </ListView>
</LinearLayout>
In the above code, we have taken name and salary as Edit text, when user click on save button it will store the data into sqlite data base. Click on refresh button after insert values to update listview from cursor.
Step 3 − Add the following code to src/MainActivity.java
package com.example.andy.myapplication;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
   Button save, refresh;
   EditText name, salary;
   private ListView listView;
   @Override
   protected void onCreate(Bundle readdInstanceState) {
      super.onCreate(readdInstanceState);
      setContentView(R.layout.activity_main);
      final DatabaseHelper helper = new DatabaseHelper(this);
      final ArrayList array_list = helper.getAllCotacts();
      name = findViewById(R.id.name);
      salary = findViewById(R.id.salary);
      listView = findViewById(R.id.listView);
      final ArrayAdapter arrayAdapter = new ArrayAdapter(MainActivity.this,        android.R.layout.simple_list_item_1, array_list);
      listView.setAdapter(arrayAdapter);
      findViewById(R.id.refresh).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            array_list.clear();
            array_list.addAll(helper.getAllCotacts());
            arrayAdapter.notifyDataSetChanged();
            listView.invalidateViews();
            listView.refreshDrawableState();
         }
      });
      findViewById(R.id.save).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            if (!name.getText().toString().isEmpty() && !salary.getText().toString().isEmpty()) {
               if (helper.insert(name.getText().toString(), salary.getText().toString())) {
                  Toast.makeText(MainActivity.this, "Inserted", Toast.LENGTH_LONG).show();
               } else {
                  Toast.makeText(MainActivity.this, "NOT Inserted", Toast.LENGTH_LONG).show();
               }
            } else {
               name.setError("Enter NAME");
               salary.setError("Enter Salary");
            }
         }
      });
   }
}
Step 4 − Add the following code to src/ DatabaseHelper.java
package com.example.andy.myapplication;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteException;
import android.database.sqlite.SQLiteOpenHelper;
import java.io.IOException;
import java.util.ArrayList;
class DatabaseHelper extends SQLiteOpenHelper {
   public static final String DATABASE_NAME = "salaryDatabase3";
   public static final String CONTACTS_TABLE_NAME = "SalaryDetails";
   public DatabaseHelper(Context context) {
      super(context,DATABASE_NAME,null,1);
   }
   @Override
   public void onCreate(SQLiteDatabase db) {
      try {
         db.execSQL(
            "create table "+ CONTACTS_TABLE_NAME +"(id INTEGER PRIMARY KEY, name text,salary text )"
         );
      } catch (SQLiteException e) {
         try {
            throw new IOException(e);
         } catch (IOException e1) {
            e1.printStackTrace();
         }
      }
   }
   @Override
   public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
      db.execSQL("DROP TABLE IF EXISTS "+CONTACTS_TABLE_NAME);
      onCreate(db);
   }
   public boolean insert(String s, String s1) {
      SQLiteDatabase db = this.getWritableDatabase();
      ContentValues contentValues = new ContentValues();
      contentValues.put("name", s);
      contentValues.put("salary", s1);
      db.insert(CONTACTS_TABLE_NAME, null, contentValues);
      return true;
   }
   public ArrayList getAllCotacts() {
      SQLiteDatabase db = this.getReadableDatabase();
      ArrayList<String> array_list = new ArrayList<String>();
      Cursor res = db.rawQuery( "select * from "+CONTACTS_TABLE_NAME+" WHERE name = 'Me'"+"AND salary = '1234567890'", null );
      res.moveToFirst();
      while(res.isAfterLast() = = false) {
         array_list.add(res.getString(res.getColumnIndex("name")));
         res.moveToNext();
      }
      return array_list;
   }
}
Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –
In the above result it is showing “Me” in list view because we have given where cause and salary should be “1234567890” with select command so it is filtering name and salary.
