合計を追跡し、テーブルに含まれる TextEdit を介してそれらを表示するアプリケーションを作成しようとしています。さまざまなテーブル、したがってさまざまな合計を追跡するために、いくつかのタブが必要です。ただし、アプリケーションがエミュレーターで起動すると、すぐに動作を停止してクラッシュします。誰が何が悪いのか教えてもらえますか?
Android コード:
public class CounterCounterActivity extends TabActivity implements OnClickListener {
/** Called when the activity is first created. */
TextView YourLife, OppLife;
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabHost=(TabHost)findViewById(R.id.tabHost);
tabHost.setup();
TabSpec spec1=tabHost.newTabSpec("Tab 1");
spec1.setContent(R.id.tab1);
spec1.setIndicator("Life");
TabSpec spec2=tabHost.newTabSpec("Tab 2");
spec2.setIndicator("+/-");
spec2.setContent(R.id.tab2);
TabSpec spec3=tabHost.newTabSpec("Tab 3");
spec3.setIndicator("Poison");
spec3.setContent(R.id.tab3);
tabHost.addTab(spec1);
tabHost.addTab(spec2);
tabHost.addTab(spec3);
tabHost.getTabWidget().getChildAt(0).getLayoutParams().height =50;
