首先，我尝试使用来自 hashmap 的数组的意图意图只是一个类并且可以工作
try{
JSONArray earthquakes = json.getJSONArray("result");
for(int i=0;i<earthquakes.length();i++){
HashMap<String, String> map = new HashMap<String, String>();
JSONObject e = earthquakes.getJSONObject(i);
map.put("id", String.valueOf(i));
map.put("tempat", "" + e.getString("place"));
map.put("kode", "" + e.getString("code"));
map.put("jarak", "Jarak: " + e.getString("distance"));
mylist.add(map);
}
}catch(JSONException e) {
Log.e("log_tag", "Error parsing data "+e.toString());
}
ListAdapter adapter = new SimpleAdapter(this, mylist , R.layout.main,
new String[] { "tempat", "jarak" },
new int[] { R.id.item_title, R.id.item_subtitle });
setListAdapter(adapter);
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
@SuppressWarnings("unchecked")
HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);
Toast.makeText(KalkulasiJson.this, "ID '" + o.get("id") + "' was clicked.", Toast.LENGTH_SHORT).show();
Intent i = new Intent(KalkulasiJson.this, Details.class);
startActivity(i);
}
});
}
然后我想用数组中的许多类和特定值来制作意图
try{
JSONArray earthquakes = json.getJSONArray("result");
for(int i=0;i<earthquakes.length();i++){
HashMap<String, String> map = new HashMap<String, String>();
JSONObject e = earthquakes.getJSONObject(i);
map.put("id", String.valueOf(i));
map.put("tempat", "" + e.getString("place"));
map.put("kode", "" + e.getString("code"));
map.put("jarak", "Jarak: " + e.getString("distance"));
mylist.add(map);
}
}catch(JSONException e) {
Log.e("log_tag", "Error parsing data "+e.toString());
}
ListAdapter adapter = new SimpleAdapter(this, mylist , R.layout.main,
new String[] { "tempat", "jarak", "kode" },
new int[] { R.id.item_title, R.id.item_subtitle, R.id.item_kode });
setListAdapter(adapter);
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
@SuppressWarnings("unchecked")
HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);
Toast.makeText(KalkulasiJson.this, "ID '" + o.get("kode") + "' was clicked.", Toast.LENGTH_SHORT).show();
TextView theCode = (TextView) findViewById(R.id.item_kode);
String Codefix = theCode.getText().toString();
if(Codefix=="kode001")
{
Intent i = new Intent(KalkulasiJson.this, Menu1.class);
startActivity(i);
}
else if(Codefix=="kode005")
{
Intent i = new Intent(KalkulasiJson.this, Menu5.class);
startActivity(i);
}
else if(Codefix=="kode003")
{
Intent i = new Intent(KalkulasiJson.this, Menu3.class);
startActivity(i);
}
else if(Codefix=="kode089")
{
Intent i = new Intent(KalkulasiJson.this, Menu89.class);
startActivity(i);
}
}
});
}
只有脚本吐司正在工作，意图不受影响
