Using onClick to open a new android activity [duplicate]

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

So instead of MaijActivity.class use the second activity name — Shobhit Puri

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
