在下面的代碼中,我想在我的行的某些「元素」上設置Onclick監聽器。我應該在哪裏放置setOnclick監聽器代碼?在活動代碼或適配器中?我想第一個,但在那種情況下,我將如何確定哪一行已被選中 (每行應該讓我看到不同的意見)?從列表視圖行進入另一個屏幕
Java代碼:
List<String[]> info=new ArrayList<String[]>();
String[] names_info=new String[5];
String[] phones_info=new String[5];
String[] map_info=new String[5];
String[] web_info=new String[5];
String[] photos_info=new String[5];
for(int i=0;i<names_info.length;i++)
{
info.add(new String[]{names_info[i],phones_info[i],map_info[i],web_info[i],photos_info[i]});
}
for (int i = 0; i < info.size(); i++) {
Log.d("TAG", "item " + i +
" name:" + info.get(i)[0] +
" info:" + info.get(i)[1]);
}
FacilitiesAdapter adapter = new FacilitiesAdapter(this,info,want_info_display,want_phone_display,want_photos_display);
//System.out.println(info[0]);
setListAdapter(adapter);
EDIT
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// When clicked, show a toast with the TextView text
//Toast.makeText(getApplicationContext(), ((TextView) arg1).getText(),
//Toast.LENGTH_SHORT).show();
Intent i33 = new Intent(HotelsScreen.this,AbousUsScreen.class);
i33.putExtra("position", arg2);
System.out.println(arg2);
System.out.println(info.get(arg2)[0]);
startActivity(i33);
}
});
我看到日誌的結果,這樣就意味着我的信息通常是獲取其結果。
這是我的適配器。
public class FacilitiesAdapter extends ArrayAdapter<String[]> {
private final Context context;
List <String[]> dataList;
public FacilitiesAdapter(Context context, List<String[]> dataList, int need_phone, int need_info, int need_photos) {
super(context, R.layout.expand_row);
this.context = context;
this.dataList = dataList;
//this.tracks_condition=tracks_condition;
//this.count=count;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.expand_row, parent, false);
System.out.println("I am here");
String[] data = dataList.get(position);
String name=data[0];
TextView textView = (TextView) rowView.findViewById(R.id.name);
System.out.println("I am in the adapter "+name);
textView.setText(name);
return rowView;
}
}
編輯1: 我我現在應該在每一個項目,看我點擊它的位置,它的名字?因爲我什麼都看不到?
這可能會去你的onCreate – dldnh 2012-03-20 13:43:49
好的這一點。我怎麼能作爲參數傳遞文本的ID(名稱和信息,我命令使用它們,以便知道如果'onItemClick'訪問與適配器具有相同的'dataList',可以打開 – 2012-03-20 13:46:47
的Whick屏幕,它可以獲取它需要的數據,然後使用'i33.putExtra(...)'類似於上面顯示的 – dldnh 2012-03-20 13:55:47
