这是我原来的代码
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);
}
}这是我修改之后的代码：目的，每次点击之后就删除该选项
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，希望对你有用！！
