Chapter 5: Intents, Broadcast Receivers, Adapters, and the Internet 128 import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; public class ContentPickerTester extends Activity { public static final int PICK_CONTACT = 1; @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.contentpickertester); } } Button button = (Button)findViewById(R.id.pick_contact_button); button.setOnClickListener(new OnClickListener() { public void onClick(View _view) { Intent intent = new Intent(Intent.ACTION_PICK, Uri.parse(“content://contacts/”)); startActivityForResult(intent, PICK_CONTACT); } }); 8. When the sub-Activity returns, use the result to populate the Text View with the selected contact’s name. @Override public void onActivityResult(int reqCode, int resCode, Intent data) { super.onActivityResult(reqCode, resCode, data); } switch(reqCode) { case (PICK_CONTACT) : { if (resCode == Activity.RESULT_OK) { Uri contactData = data.getData(); Cursor c = managedQuery(contactData, null, null, null, null); c.moveToFirst(); String name; name = c.getString(c.getColumnIndexOrThrow(People.NAME)); TextView tv; tv = (TextView)findViewById(R.id.selected_contact_textview); tv.setText(name); } break; } } 9. With your test harness complete, simply add it to your application manifest. You’ll also need to add a READ_CONTACTS permission within a uses-permission tag, to allow the application to access the contacts database.

The contact picker Activity should be shown as in Figure 5-1. Figure 5-1 Once you select a contact, the parent Activity should return to the foreground with the selected contact name displayed, as shown in Figure 5-2. Figure 5-2 129
