這是我原來的代碼

public class FileDeleteActivity extends ListActivity {
??? /** Called when the activity is first created. */
?ArrayList<String> listStr=new ArrayList<String>();
?private Handler handler=null;

??? @Override
??? public void onCreate(Bundle savedInstanceState) {
??????? super.onCreate(savedInstanceState);
??????? setContentView(R.layout.main);
??????? final ListView list=new ListView(this);
??????? listStr=getDataSource();
??????? Adapter adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listStr);
??????? list.setAdapter(adapter);
??????? setListAdapter(adapter);

?}
???
??? private ArrayList<String> getDataSource(){
??? ?ArrayList<String> source=new ArrayList<String>();
??? ?source.add("11");
??? ?source.add("aa");
??? ?source.add("Aa");
??? ?source.add("EE");
??? ?source.add("--23");
??? ?return source;
??? }
???
??? @Override
??? protected void onListItemClick(ListView l, View v, int position, long id){
??? ?listStr.remove(position);
?????super.onListItemClick(l, v, position, id);
??? }
}

這是我修改之后的代碼：目的，每次點(diǎn)擊之后就刪除該選項(xiàng)

public class FileDeleteActivity extends ListActivity {
??? /** Called when the activity is first created. */
?ArrayList<String> listStr=new ArrayList<String>();
?private Handler handler=null;
?private ArrayAdapter<String> adapter=null;
??? @Override
??? public void onCreate(Bundle savedInstanceState) {
??????? super.onCreate(savedInstanceState);
??????? setContentView(R.layout.main);
??????? final ListView list=new ListView(this);
??????? listStr=getDataSource();
??????? adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listStr);
??????? list.setAdapter(adapter);
??????? setListAdapter(adapter);

? }
???
??? private ArrayList<String> getDataSource(){
??? ?ArrayList<String> source=new ArrayList<String>();
??? ?source.add("11");
??? ?source.add("aa");
??? ?source.add("Aa");
??? ?source.add("EE");
??? ?source.add("--23");
??? ?return source;
??? }
???
??? @Override
??? protected void onListItemClick(ListView l, View v, int position, long id){
??? ?listStr.remove(position);
??? ?adapter.notifyDataSetChanged();//更新一下就行了
?????super.onListItemClick(l, v, position, id);
??? }
}

好了，希望對你有用！！
