画面遷移

最初にリストを表示してリスト選択で画面遷移する例
AndroidManifest.xml にActivityを登録すること

リスト表示画面

public class MainActivity extends ListActivity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, SampleActivity.VIEWS));
 } 
 @Override
 protected void onListItemClick(ListView l, View v, int position, long id) {
  super.onListItemClick(l, v, position, id);
  Log.i("mytest" , "onListItemClick =" + position);
  Intent i = new Intent(this, SampleActivity.class);
  i.putExtra(SampleActivity.SAMPLE_NO, position);
  startActivity(i);
 }
}

リスト選択後の画面

public class SampleActivity extends Activity {

 public static final String SAMPLE_NO = "sample no";
 public static final String[] VIEWS = { "1. sample1", "2. sample2", "3. sample3"};

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  Intent i = getIntent();
  int no = i.getIntExtra(SAMPLE_NO, 0);
  Log.i("myteset", "SampleActivity.onCreate " + no);
  switch (no) {
  case 0:
   setContentView(new MyView1(this));
   break;
  case 1:
   setContentView(new MyView2(this));
   break;
  case 2:
   setContentView(new MyView3(this));
   break;
  default:
   setContentView(new MyView1(this));
   break;
  }
 }
}
