问题描述
喜在我的项目我使用的是自定义适配器。当其中包含列表视图打开，图像视图和文本视图的活动出现在第一和经过时间观dissappears.I不可能找到一个解决方案做u有什么想法？
编辑：
此外，它工作在模拟器，但不正常的设备吗？
在这里我设置适配器类：
保护无效的onCreate（捆绑savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_person_deatil）;
意向detailIntent = getIntent（）;
GSON GSON =新GSON（）;
串物镜= detailIntent.getStringExtra（物镜）;
PeopleListItem人= gson.fromJson（OBJ，PeopleListItem.class）; ListView控件LW =（ListView控件）findViewById（R.id.perdetLw）; PeopleListItem [] =名单新PeopleListItem [6];
的for（int i = 0;我6;;我++）{
名单由[i] =人;
} 动作条AB = getActionBar（）;
ab.setDisplayHomeAsUpEnabled（真）;
ab.setTitle（people.getName（））;
ab.setIcon（R.drawable.ic_action_person）; PeopleDetailArrayAdapter ADP =新PeopleDetailArrayAdapter（这一点，R.layout.person_detail_item，清单）;
lw.setAdapter（ADP）;}
类的自定义适配器：
公共类PeopleDetailArrayAdapter扩展ArrayAdapter＆LT; PeopleListItem＆GT; {INT资源;
上下文语境;
诠释计数= 0;
公共PeopleDetailArrayAdapter（上下文的背景下，INT资源，
PeopleListItem []列表）{
超级（上下文，资源清单）;
this.resource =资源;
this.context =背景;
}
@覆盖
公共查看getView（INT位置，查看convertView，父母的ViewGroup）{
// TODO自动生成方法存根 最后PeopleListItem peopleObj =的getItem（位置）;
LayoutInflater layoutInflator =（LayoutInflater）context.getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
查看的ListViewItem = layoutInflator.inflate（资源，NULL）; 最终的TextView的TextView =（TextView中）listViewItem.findViewById（R.id.detailTw）;
最终的TextView textView1 =（TextView中）listViewItem.findViewById（R.id.detailTw1）;
最后ImageView的ImageView的=（ImageView的）listViewItem.findViewById（R.id.detailIw）; // IMG观点kişininresmine戈尔değişmeli
最后ImageView的imageView1 =（ImageView的）listViewItem.findViewById（R.id.detailIw1）; 开关（计数）{
情况下0：
textView.setText（标题：）;
字符串title = peopleObj.getTitle（）;
textView1.setText（职称）;
打破;
情况1：
textView.setText（部）;
字符串DEP = peopleObj.getDepart（）;
textView1.setText（DEP）;
打破;
案例2：
textView.setText（工作电话：）;
串的wp = peopleObj.getWorkPhone（）;
textView1.setText（WP）;
imageView.setVisibility（ImageView.VISIBLE）;
打破;
案例3：
textView.setText（手机）;
串熔点= peopleObj.getMobilePhone（）;
textView1.setText（MP）;
imageView.setVisibility（ImageView.VISIBLE）;
imageView1.setVisibility（ImageView.VISIBLE）;
打破;
情况4：
textView.setText（电子邮件：）;
字符串email = peopleObj.getEmail（）;
textView1.setText（电子邮件）;
打破;
情况5：
textView.setText（经理：）;
字符串男子= peopleObj.getManager（）;
textView1.setText（人）;
打破;
默认：
打破;
}
算上++;
返回ListViewItem的;
}}
解决方案
我解决了问题，通过使用位置而不是使用计数
公共类PeopleDetailArrayAdapter扩展ArrayAdapter＆LT; PeopleListItem＆GT; {INT资源;
上下文语境;公共PeopleDetailArrayAdapter（上下文的背景下，INT资源，
PeopleListItem []列表）{
超级（上下文，资源清单）;
this.resource =资源;
this.context =背景;
}
@覆盖
公共查看getView（INT位置，查看convertView，父母的ViewGroup）{
// TODO自动生成方法存根 最后PeopleListItem peopleObj =的getItem（位置）;
LayoutInflater layoutInflator =（LayoutInflater）context.getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
查看的ListViewItem = layoutInflator.inflate（资源，NULL）; 最终的TextView的TextView =（TextView中）listViewItem.findViewById（R.id.detailTw）;
最终的TextView textView1 =（TextView中）listViewItem.findViewById（R.id.detailTw1）; 开关（位置）{
情况下0：
textView.setText（标题）;
字符串title = peopleObj.getTitle（）;
textView1.setText（职称）;
打破;
情况1：
textView.setText（部）;
字符串DEP = peopleObj.getDepart（）;
textView1.setText（DEP）;
打破;
案例2：
textView.setText（工作）;
串的wp = peopleObj.getWorkPhone（）;
textView1.setText（WP）;
打破;
案例3：
textView.setText（手机）;
串熔点= peopleObj.getMobilePhone（）;
textView1.setText（MP）;
打破;
情况4：
textView.setText（电子邮件）;
字符串email = peopleObj.getEmail（）;
textView1.setText（电子邮件）;
打破;
情况5：
textView.setText（经理）;
字符串男子= peopleObj.getManager（）;
textView1.setText（人）;
打破;
} 返回ListViewItem的;
}
}
Hi in my project i am using an custom adapter. When the activity which contains listview opened, image views and text views appears at first and after a time views dissappears.I couldnt find a solution do u have any idea? edit: Also it works on emulator but dont work on normal device?
The class where i set adapter:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_person_deatil);
Intent detailIntent = getIntent();
Gson gson = new Gson();
String obj = detailIntent.getStringExtra("obj");
PeopleListItem people = gson.fromJson(obj, PeopleListItem.class);
ListView lw = (ListView) findViewById(R.id.perdetLw);
PeopleListItem[] list = new PeopleListItem[6];
for(int i=0; i<6; i++){
list[i] = people;
}
ActionBar ab = getActionBar();
ab.setDisplayHomeAsUpEnabled(true);
ab.setTitle(people.getName());
ab.setIcon(R.drawable.ic_action_person);
PeopleDetailArrayAdapter adp = new PeopleDetailArrayAdapter(this, R.layout.person_detail_item, list);
lw.setAdapter(adp);
}
The class of custom Adapter:
public class PeopleDetailArrayAdapter extends ArrayAdapter<PeopleListItem> {
int resource;
Context context;
int count = 0;
public PeopleDetailArrayAdapter(Context context, int resource,
PeopleListItem[] list) {
super(context, resource, list);
this.resource = resource;
this.context = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
final PeopleListItem peopleObj = getItem(position);
LayoutInflater layoutInflator = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View listViewItem = layoutInflator.inflate(resource, null);
final TextView textView = (TextView) listViewItem.findViewById(R.id.detailTw);
final TextView textView1 = (TextView) listViewItem.findViewById(R.id.detailTw1);
final ImageView imageView = (ImageView) listViewItem.findViewById(R.id.detailIw);//img view kişinin resmine göre değişmeli
final ImageView imageView1 = (ImageView) listViewItem.findViewById(R.id.detailIw1);
switch (count) {
case 0:
textView.setText("Title:");
String title = peopleObj.getTitle();
textView1.setText(title);
break;
case 1:
textView.setText("Department:");
String dep = peopleObj.getDepart();
textView1.setText(dep);
break;
case 2:
textView.setText("Work Phone:");
String wp = peopleObj.getWorkPhone();
textView1.setText(wp);
imageView.setVisibility(ImageView.VISIBLE);
break;
case 3:
textView.setText("Mobile Phone:");
String mp = peopleObj.getMobilePhone();
textView1.setText(mp);
imageView.setVisibility(ImageView.VISIBLE);
imageView1.setVisibility(ImageView.VISIBLE);
break;
case 4:
textView.setText("Email:");
String email = peopleObj.getEmail();
textView1.setText(email);
break;
case 5:
textView.setText("Manager:");
String man = peopleObj.getManager();
textView1.setText(man);
break;
default:
break;
}
count++;
return listViewItem;
}
}
解决方案
i solved problem by using position instead of using count
public class PeopleDetailArrayAdapter extends ArrayAdapter<PeopleListItem> {
int resource;
Context context;
public PeopleDetailArrayAdapter(Context context, int resource,
PeopleListItem[] list) {
super(context, resource, list);
this.resource = resource;
this.context = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
final PeopleListItem peopleObj = getItem(position);
LayoutInflater layoutInflator = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View listViewItem = layoutInflator.inflate(resource, null);
final TextView textView = (TextView) listViewItem.findViewById(R.id.detailTw);
final TextView textView1 = (TextView) listViewItem.findViewById(R.id.detailTw1);
switch (position) {
case 0:
textView.setText("Title");
String title = peopleObj.getTitle();
textView1.setText(title);
break;
case 1:
textView.setText("Department");
String dep = peopleObj.getDepart();
textView1.setText(dep);
break;
case 2:
textView.setText("Work");
String wp = peopleObj.getWorkPhone();
textView1.setText(wp);
break;
case 3:
textView.setText("Mobile");
String mp = peopleObj.getMobilePhone();
textView1.setText(mp);
break;
case 4:
textView.setText("Email");
String email = peopleObj.getEmail();
textView1.setText(email);
break;
case 5:
textView.setText("Manager");
String man = peopleObj.getManager();
textView1.setText(man);
break;
}
return listViewItem;
}
}
