我必须通过在 android 中使用 arrayadapter 将项目添加到列表视图中,所以完成了编码,如果我运行项目,应用程序会强制关闭,甚至在清单中提到了该活动,但仍然找不到崩溃的确切原因。
public class Jobs extends ListActivity {
private TextView selection;
private static final String[] items={"Computer Hardware", "Featured", "Information Technology", "Software", "Technical"
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.jobs);
selection = (TextView)findViewById(R.id.selection);
ListView list = (ListView)findViewById(android.R.id.list);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.jobs, items);
setListAdapter(adapter);
}
public void onListItemClick(ListView parent, View v, int position, long id)
{
selection.setText(items[position]);
}
}
