Adding Buttons

Update CrimeFragment’s layout to include new buttons for accusation and tattling: namely, a suspect button and a report button. First, add the strings that these buttons will display.

Listing 15.1  Adding button strings (res/values/strings.xml) 

<resources>
    ...
    <string name="new_crime">New Crime</string>
    <string name="crime_suspect_text">Choose Suspect</string>
    <string name="crime_report_text">Send Crime Report</string>
</resources>

In res/layout/fragment_crime.xml, add two button widgets, as shown in Listing 15.2.

Listing 15.2  Adding CHOOSE SUSPECT and SEND CRIME REPORT buttons (res/layout/fragment_crime.xml) 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              ... >
    ...
    <CheckBox
            android:id="@+id/crime_solved"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/crime_solved_label"/>

    <Button
            android:id="@+id/crime_suspect"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/crime_suspect_text"/>

    <Button
            android:id="@+id/crime_report"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/crime_report_text"/>
</LinearLayout>

Preview the updated layout or run CriminalIntent to confirm that your new buttons are in place.
