Then  go to Text view of activity_main.xml  

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <TextView android:text="@string/hello_world" android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:id="@+id/textView" />

/** adding button to the view*/
    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="New Button"        android:id="@+id/button"        android:layout_below="@+id/textView"        android:layout_centerHorizontal="true"        android:layout_marginTop="85dp" />


</RelativeLayout>

import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

/** Ater AppCompatActivity  you should write implements then onclicklistner and enter*/
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private Button btn;
   
    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn =(Button)findViewById(R.id.button);
        btn.setOnClickListener(this);/**btn lai onclicklistner sanga set gareko*/        
    }

public void onClick(View view){

        Intent intent = new Intent(getApplicationContext(), SecondActivity.class);/**intent le yauta activity bata aarko activity ma shift garna madat garcha*/
        startActivity(intent);

       }

}

    <application        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >
        <activity            android:name=".MainActivity"            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity            android:name=".SecondActivity"            android:label="@string/title_activity_second" >
