所以,我打算做一個列表視圖,如果其中一個項目點擊,它會轉到其他活動。很明顯,我想用額外的意圖。listview onitemclick不能引用
但是在我的代碼中,額外功能並沒有受到重視。 我試着引用額外的準確值,它的工作,但如果我把額外的引用我的對象/變量,它將無法正常工作。
到目前爲止,我的代碼是這樣
public class bulan extends ListActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tagihan_list);
Intent i = getIntent();
final String no_pel = i.getStringExtra("no_pel");
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("nopel", no_pel));
ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
JSON json = new JSON();
JSONObject jobj = json.getJSON("http://10.0.2.2/KP/tagihan.php", pairs);
try {
int length = jobj.getInt("panjang");
for(int n = 1; n <= length; n++){
String m = Integer.toString(n);
JSONObject row = jobj.getJSONObject(m);
String id_tagihan = "No. tagihan : " + row.getString("id");
String bulan = row.getString("bulan");
String tahun = row.getString("tahun");
String tagihan = "Rp. " + row.getString("tagihan");
String status = row.getString("status");
HashMap<String, String> map = new HashMap<String, String>();
map.put("id_tagihan", id_tagihan);
map.put("bulan", bulan);
map.put("tahun", tahun);
map.put("tagihan", tagihan);
map.put("status", status);
list.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
ListAdapter adapter = new SimpleAdapter(this, list, R.layout.list,
new String[] {"id_tagihan","bulan","tahun","tagihan","status"}, new int[] {
R.id.id_tagihan, R.id.bulan, R.id.tahun, R.id.tagihan, R.id.status});
setListAdapter(adapter);
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
String sid = ((TextView) view.findViewById(R.id.id_tagihan)).getText().toString();
String snopel = no_pel;
Intent i = new Intent(bulan.this, rincian.class);
i.putExtra("id", sid);
i.putExtra("no_pel", snopel);
startActivity(i);
}
});
}
}
就像我之前解釋說,這是這部分
Intent i = new Intent(bulan.this, rincian.class);
i.putExtra("id", sid);
i.putExtra("no_pel", snopel);
startActivity(i);
是改變我的代碼,如果我寫他們喜歡這個
Intent i = new Intent(bulan.this, rincian.class);
i.putExtra("id", "00001");
i.putExtra("no_pel", "0620120001");
startActivity(i);
工作
「not reffering」then what are getting null? –
