コールバック関数で実行すると、次のコードが例外をスローするのはなぜですか?
public class TeamPointsDayActivity extends Activity implements IMyCallBack<String>, IMyCallBackTeamPoints {
private String mDay;
private URLHandler mUrlHandler;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_select_team);
getActionBar().setDisplayHomeAsUpEnabled(true);
Intent intent = getIntent();
mDay = intent.getStringExtra(MainActivity.EXTRA_DAY);
// !!!!!Calling createTable() here works fine!!!!
}
private void createTable() {
TableLayout table = (TableLayout)findViewById(R.id.mytabletest);
TableRow tr = new TableRow(TeamPointsDayActivity.this);
tr.setLayoutParams(new TableRow.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
tr.setPadding(8, 8, 8, 8);
TextView labelTV = new TextView(TeamPointsDayActivity.this);
labelTV.setText("test1111111");
labelTV.setBackgroundResource(R.drawable.cell_shape);
labelTV.setPadding(3, 3, 3, 3);
tr.addView(labelTV);
table.addView(tr, new TableRow.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
}
public void onTeamPointsReadComplete(IGameData data) {
// Do stuff with "data"...not relevant
// Adding following line here in this callback function will throw an exception
createTable();
}
}

本当に奇妙です...
誰かがここで何が悪いのか教えてもらえますか? それ以外の場合、コールバック関数からのデータを使用して動的テーブル行を作成するにはどうすればよいですか?
編集: activity_select_team.xml ファイルを投稿するのを忘れました:

よろしく、サンドロ
