Using onClick to open a new android activity

Question

I've seen a few other questions similar to this, but I still cant seem to get an answer.

What I would ideally like is to use the intent method as shown below to switch to another activity.

Here is my MainActivity.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}
public void sendCalc (View view){
    Intent intent = new Intent (this, MainActivity.class);
    startActivity(intent);
}

and this is my second activity: {

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

    Intent intent = getIntent();
}

and here is my xml file for the button.

 <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/createCalc"
        android:onClick="sendCalc"
        android:elevation="2dp" />

Also, I have added the second activity in the manifest file.

Thank you in advance for the help.

What is the name of second activity? Is `MainActivity` the second activity which you want to start? `Intent intent = new Intent (this, MainActivity.class);` — Shobhit Puri, Nov 15 '16 at 17:20
So instead of MaijActivity.class use the second activity name — Shobhit Puri, Nov 15 '16 at 18:12

I'm gonna give you an example of one of my app's code to change to the next activity

NextPage = (Button)findViewById(R.id.button);

    NextPage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent (MainActivity.this, Main2Activity.class);
            startActivity(intent);

        }
    });

You put this over the:

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

You need to have a button to do a OnClick intent "NextPage" is the Button name in the MainActivity.class – Marroquino Nov 15 '16 at 18:12
You need to create another activity so it can move to there else you wont get anything from this code – Marroquino Nov 15 '16 at 18:13
I have another activity its called calculation. here is it in full: – Muaaz Kasker Nov 15 '16 at 18:15
`package com.example.muaaz.emscalculator; import android.content.Intent; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; public class calculation extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Intent intent = getIntent(); } } ` @Marroquino – Muaaz Kasker Nov 15 '16 at 18:16

I get an error saying that it needs something like a `public void` or something (your given code). invalid method type – Muaaz Kasker Nov 15 '16 at 18:21
