Java Question

onClick view is already defined

I am trying to work with two buttons on one screen and I want to have two different actions occur when each button is clicked. This is my code and I am getting the error message onClick view is already defined on the method titles of both onClick methods. Any help is greatly appreciated.

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity2 extends AppCompatActivity implements View.OnClickListener {

private Button button3;
private Button button2;
private EditText editText;
private EditText editText9;
private EditText editText10;
private EditText editText11;
private EditText editText12;
private EditText editText13;
private EditText editText14;
private TextView textView;
private TextView textView22;
private View view;

protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity2_main);
Intent intent = getIntent();
button3 = (Button) findViewById(R.id.button3);
button3.setOnClickListener(this);
button2 = (Button) findViewById(R.id.button2);
button2.setOnClickListener(this);

editText = (EditText) findViewById(R.id.editText);
editText9 = (EditText) findViewById(R.id.editText9);
editText10 = (EditText) findViewById(R.id.editText10);
editText11 = (EditText) findViewById(R.id.editText11);
editText12 = (EditText) findViewById(R.id.editText12);
editText13 = (EditText) findViewById(R.id.editText13);
editText14 = (EditText) findViewById(R.id.editText14);
textView = (TextView) findViewById(R.id.textView);
textView22 = (TextView) findViewById(R.id.textView22);


}
public void onClick (View view) {
this.view = view;
if (view.getId() == R.id.button3) {
Intent intent = new Intent(MainActivity2.this, MainActivity.class);
MainActivity2.this.startActivity(intent);
}
}


public void onClick (View view){
if (view.getId() == R.id.button2) {
String value8 = editText.getText().toString();
String value9 = editText9.getText().toString();
String value10 = editText10.getText().toString();
String value11 = editText11.getText().toString();
String value12 = editText12.getText().toString();
String value13 = editText13.getText().toString();
String value14 = editText14.getText().toString();
}

}

}

Answer

You have two onClick methods with the same parameters so it doesn't know which to use. Combine the two and it should work.
