Android java button value check-CodePudding

I'm trying to learn basic stuff in android studio with java. I need to create 1 activity where we need a Button and a text to input. When the button is clicked to check is the input value is between 3 words "Primary, Secondary , Higher). Here is the mainactivity code

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

private Button button;
private int check = 1;

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


    button = findViewById(R.id.button);
    button.setOnClickListener(this);
}


@Override
public void onClick(View view) {

    // Check for valid education


    // if yes -> next view
    if (check == 0 ) {
            Toast.makeText(this, R.string.error, Toast.LENGTH_SHORT).show();
    } else if ( check == 1) {
        startActivity(new Intent(this, Activity2.class));
    }
}

}

Follow this way

add input field in you xml file above button view .

<EditText
      android:id="@ id/edu"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:hint="Enter your education" />

In your mainactivity.java

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

private Button button;
private EditText edu; 


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

    edu = findViewById(R.id.edu);
    button = findViewById(R.id.button);

  button.setOnClickListener(
            new View.OnClickListener() {
 
      @Override
       public void onClick(View v){

       String check_edu= edu.getText().toString().toLowerCase();

      if ( check_edu.equals("primary") || check_edu.equals("secondary") || check_edu.equals("higher") ){
           startActivity(new Intent(this, Activity2.class));
                   
              } else {
                   Toast.makeText(this, R.string.error, Toast.LENGTH_SHORT).show();
                 }

            });


  }
}
