Not a valid result with a checkBox

I try to use CheckBox in my app. The status of checkBox(checked/uncheked), I use in putExtra and then in next activity, depending on the result I send a query to database. The problem is with multiply check.

public class Myactivity extends AppCompatActivity implements View.OnClickListener{

CheckBox mCheck1;
CheckBox mCheck2;
CheckBox mCheck3;
ImageButton mImageButton;

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

    mImageButton = findViewById(R.id.button_ok_option);
    mCheck1 = findViewById(R.id.checkBox1);
    mCheck2 = findViewById(R.id.checkBox2);
    mCheck3 = findViewById(R.id.checkBox3);

    mImageButton.setOnClickListener(this);
}

@Override
public void onClick(View v) {
    Intent intent = new Intent(this, Choose_meet_activity.class);
    intent.putExtra("1", mCheck1.isChecked());
    intent.putExtra("2", ((mCheck1.isChecked()) && (mCheck2.isChecked()));
    intent.putExtra("3", mCheck2.isChecked());
    startActivity(intent)
}
}

For example, if I use mCheck1 - in database searching results with "colour":"red",mCheck2 - "size":"big". When I press the Check1 - all good, all results with "red" come to me. And the same positive result with mCheck2, that is, under any single condition. But when I pressed mCheck1 && mCheck2 - all results with color:"red", even if "size" not "big" come back to me. What is wrong?
