how to move the buttons from one page to another using android codings

you have to use startintenet method after you add your activity to your AndroidManifest.xml

<pre lang="xml"><activity android:name=".ListViewExampleActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

then you can use on buttonclick the :

Button orderButton = (Button)findViewById(R.id.order);
orderButton.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View view) {
    Intent intent = new Intent(FirstActivity.this, OrderScreen.class);
    startActivity(intent);
  }
});
