About this task

For more information, review layouts and activities on the Android developer site.

Procedure

Create the related warranty display page layout.

In the Package Explorer, navigate to res > layout.
Right click and select New > Android XML File.
In the file creation dialog, name the file catalog_product_warranty.xml. Notice that Layout is already selected as the type of resource to create and LinearLayout is selected by default. Keep these default values and click Finish.
Switch to the XML view.

Replace existing code with the following code in the file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical" >
  
  <LinearLayout
    android:orientation="vertical"
    android:background="@drawable/category_name_bg"
    android:layout_width="match_parent"
    android:layout_weight="match_parent"
    android:layout_weight="1">
    
    <TextView android:id="@+id/warrantyTermLabel"
    android:layout_height="wrap_content"
    android:layout_marginBottom="3dp"
    android:text="@String/Warranty1"
    style="@style/BoldText"/>
		 
    <TextView android:id="@+id/warrantyTerm"	
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:layout_marginBottom="1dp"
    android:layout_marginLeft="3dp"
    android:layout_marginRight="1dp"
    android:layout_marginTop="1dp"
    android:padding="5dp"
    android:text="@string/WarrantyTerm"
    style="@style/BoldText"/>
    
    <TextView android:id="@+id/warrantyTypeLabel"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:layout_marginBottom="3dp"
    android:text="@string/Warranty2"
    style="@style/BoldText"/>
    
    <TextView android:id="@+id/warrantyType"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:layout_marginBottom="1dp"
    android:layout_marginLeft="3dp"
    android:layout_marginRight="1dp"
    android:layout_marginTop="1dp"
    android:padding="5dp"
    android:text="@string/WarrantyType"
    style="@style/BoldText"/>
    
  </LinearLayout>
</LinearLayout>

The first section defines the related warrantyTerm display area while the second section defines the related warrantyType display area. Notice that the text is reusing the resource string that you created in the previous part. Warranty information is shown in a grid layout.

Save the file and before you close it, switch back to the Graphical Layout tab to see your new page layout.

Create an activity for the related warranty display page

In the Package Explorer, navigate to src > com.ibm.commerce.android.nativeapp.mobile.activity.catalog
Right-click and select New > Class
Name the class WarrantyActivity and set the superclass to android.app.Activity. Click Finish.

Implement the following class. The R class is auto-generated.

package com.ibm.commerce.android.nativeapp.mobile.activity.catalog;

import com.ibm.commerce.android.nativeapp.mobile.activity.R;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class WarrantyActivity extends Activity {

public void onCreate(Bundle bundle)
{
super.onCreate(bundle);
Bundle extras = getIntent().getExtras();

// Get the String value from the parameter passed from putExtra method
String warrantyTerm = extras.getString("warrantyTerm");
String warrantyType = extras.getString("warrantyType");

// Set the screen content from a layout resource.
setContentView(R.layout.catalog_product_warranty);

//Set the text value
TextView tv1 = (TextView)findViewById(R.id.warrantyTerm);
tv1.setText(warrantyTerm);
TextView tv2 = (TextView)findViewById(R.id.warrantyType);
tv2.setText(warrantyType);
}
	}

Save and close the file.

Register the new activity in the manifest file
1. In the Package Explorer view, open the AndroidManifest.xml file.
2. Click the AndroidManifest.xml tab to see the code, and scroll to the bottom on the file.
3. Add your new activity before the </application> tag.
```
<activity
  android:name="com.ibm.commerce.android.nativeapp.mobile.activity.catalog.WarrantyActivity"
  android:configChanges="locale|orientation|keyboard"
  android:screenOrientation="portrait">
</activity>
```
4. Save and close the file.
If there are errors in any of your files, clean your project.
1. In the Package Explorer view, right-click MyProject and select Properties > Java Compiler.
2. Set Compiler compliance level to 1.6 and press OK.
3. In Eclipse, select Project > Clean...
  All errors should now be fixed.
