如何将listview所选项目传递到listview中的下一个活动？我通过从我的数据库中获取的id传递它，当我将所选列表传递到textview时它正在工作。但我不知道如何将它传递给listview。有人帮我。
这是我将id传递给下一个活动的代码
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent (this, Sample.class);
HashMap<String,String> map =(HashMap)parent.getItemAtPosition(position);
String s_id = map.get(Config.TAG_s_id).toString();
String s_name = map.get(Config.TAG_s_name).toString();
String s_gender = map.get(Config.TAG_s_gender).toString();
String teamone = map.get(Config.TAG_teamone).toString();
String teamonepts = map.get(Config.TAG_teamonepts).toString();
String teamtwo = map.get(Config.TAG_teamtwo).toString();
String teamtwopts = map.get(Config.TAG_teamtwopts).toString();
intent.putExtra(Config.S_id,s_id);
intent.putExtra(Config.S_name,s_name);
intent.putExtra(Config.S_gender,s_gender);
intent.putExtra(Config.Teamone,teamone);
intent.putExtra(Config.Teamonepts,teamonepts);
intent.putExtra(Config.Teamtwo,teamtwo);
intent.putExtra(Config.Teamtwopts,teamtwopts);
startActivity(intent);
}
}
这是我的下一个活动
editTextId = (EditText) findViewById(R.id.editTextId);
title1ID = (TextView) findViewById(R.id.s_genderID);
contentID = (TextView) findViewById(R.id.s_nameID);
dateID = (TextView) findViewById(R.id.teamone);
teamoneptsID = (TextView) findViewById(R.id.teamonepts);
teamtwoID = (TextView) findViewById(R.id.teamtwo);
teamtwoptsID = (TextView) findViewById(R.id.teamtwopts);
listview = (ListView) findViewById(R.id.listView);
Typeface font = Typeface.createFromAsset(getAssets(), "arial.ttf");
title1ID.setTypeface(font);
contentID.setTypeface(font);
dateID.setTypeface(font);
editTextId.setText(id);
title1ID.setText(titl);
contentID.setText(cont);
dateID.setText(date);
teamoneptsID.setText(teamonepts);
teamtwoID.setText(teamtwo);
teamtwoptsID.setText(teamtwopts);

try {

使用像这样的模态类可以帮助
public class Version implements Serializable{
public Version(String name, String version, String released) {
this.name = name;
this.version = version;
this.released = released;
}
private String name;
private String version;
private String released;
private String api;
private String image;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public String getReleased() {
return released;
}
public void setReleased(String released) {
this.released = released;
}
public String getApi() {
return api;
}
public void setApi(String api) {
this.api = api;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
}
并使用构造函数获取并设置所有值为
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
HashMap<String, String> selected = androidversions.get(position);
Version verison = new Version(selected.getString("name"),selected.getString("version"),selected.getString("released"))
Intent intent = new Intent(MainActivity.this, DetailActivity.class);
intent.putExtra("verisonDetails", verison);
startActivity(intent);
}
});
在详细信息活动中，您可以获得
version = (Version) getIntent().getExtras().getSerializable("verisonDetails");
并将每个值作为version.get ..

您可以在其他列表视图中使用这些详细信息：
private void showResult(){
JSONObject jsonObject = null;
ArrayList<HashMap<String,String>> list = new ArrayList<>();
try {
jsonObject = new JSONObject(JSON_STRING);
JSONArray result = jsonObject.getJSONArray(Config.TAG_JSON_ARRAY2);
//Get details from intent that is passed from previous listview and set it to new list.
HashMap<String,String> map = new HashMap<>();
map.put(Config.TAG_teamone, teamone);
map.put(Config.TAG_teamonepts,teamonepts);
map.put(Config.TAG_teamtwo,teamtwo);
map.put(Config.TAG_teamtwopts,teamonepts);
map.put(Config.TAG_s_name,s_name);
map.put(Config.TAG_s_gender,s_gender);
list.add(map);
for(int i = 0; i<result.length(); i++){
JSONObject jo = result.getJSONObject(i);
String teamone = jo.getString(Config.TAG_teamone);
String teamonepts = jo.getString(Config.TAG_teamonepts);
String teamtwo = jo.getString(Config.TAG_teamtwo);
String teamtwopts = jo.getString(Config.TAG_teamtwopts);
String s_name = jo.getString(Config.TAG_s_name);
String s_gender = jo.getString(Config.TAG_s_gender);
HashMap<String,String> match = new HashMap<>();
match.put(Config.TAG_teamone, teamone);
match.put(Config.TAG_teamonepts,teamonepts);
match.put(Config.TAG_teamtwo,teamtwo);
match.put(Config.TAG_teamtwopts,teamtwopts);
match.put(Config.TAG_s_name,s_name);
match.put(Config.TAG_s_gender,s_gender);
list.add(match);
}
} catch (JSONException e) {
e.printStackTrace();
}
ListAdapter adapter = new SimpleAdapter(
Sample.this, list, R.layout.gamesadapterlayout,
new String[]{Config.TAG_teamone,Config.TAG_teamonepts, Config.TAG_teamtwo, Config.TAG_teamtwopts, Config.TAG_s_name, Config.TAG_s_gender},
new int[]{ R.id.team1, R.id.score1, R.id.team2, R.id.score2, R.id.Type, R.id.s_gender});
listview.setAdapter(adapter);
}
