问题描述
我已经在parse.com dashboard.i使这个阵列列是能从我的应用程序在数组中添加值,但中号无法获取数组或列表,并使用它的所有功能(即使大小())给该行零点例外。
我已经使用了许多解决方案,但没有奏效。
我的code,其中它给错误。
=实(的TextView)v.findViewById(R.id.realtext);
假=(TextView中)v.findViewById(R.id.faketext);
realbutton =(的ImageButton)v.findViewById(R.id.realbutton);
fakebutton =(的ImageButton)v.findViewById(R.id.fakebutton);
real.setText(将String.valueOf(news.getRealvote()));
fake.setText(将String.valueOf(news.getFake()));
fakebutton.setOnClickListener(新View.OnClickListener(){ @覆盖
公共无效的onClick(视图v){
// TODO自动生成方法存根 news.setuserArray(news.getAuthor()getUsername());
清单<&的parseObject GT;一个= news.getUserArray();
Toast.makeText(C,a.toString(),Toast.LENGTH_SHORT).show(); //用a.size()等任何东西给任何错误 news.setFake();
news.saveInBackground();
fake.setText(将String.valueOf(news.getFake())); realbutton.setVisibility(View.GONE);
fakebutton.setVisibility(View.GONE); }
});
这是我的getUserArray()方法
公开名单<&的parseObject GT; getUserArray(){ 返回的GetList(users_rated);
}
存储数据的方法的工作
公共无效setuserArray(字符串文件){
addUnique(users_rated文件);
}
我已经尝试了很多,但没有success.plss帮我取回数组。
你要求列表适配器?
公共类Customnewslistview扩展ParseQueryAdapter<新闻> {上下文℃;公共Customnewslistview(上下文的背景下){
超(背景下,新闻报);
C =背景;
}@覆盖
公共查看getItemView(最终新闻新闻,视图V的ViewGroup以及母公司){ 如果(V == NULL){
最终的TextView真实;
最终的TextView假的;
最终的ImageButton realbutton;
最终的ImageButton fakebutton;
最终进度装载机;
V = View.inflate(的getContext(),R.layout.item_list_news_public,NULL); 装载机=(进度)v.findViewById(R.id.eachnewsloder); ParseImageView newsImage =(ParseImageView)V
.findViewById(R.id.icon);
ParseFile photoFile = news.getParseFile(照片);
如果(photoFile!= NULL){
newsImage.setParseFile(photoFile);
newsImage.loadInBackground(新GetDataCallback(){

公共无效完成(字节[]数据,ParseException的E){

fakebutton.setVisibility(View.GONE); }
});
fakebutton.setOnClickListener(新View.OnClickListener(){ @覆盖
公共无效的onClick(视图v){

text.setText(news.getTitle());
//图像解析
ParseImageView newsImage =(ParseImageView)D

这是我用得到的DB的
对象:列表
的方法TrackedLocation
ParseQuery<&的parseObject GT;查询= ParseQuery.getQuery(TrackedLocation);
query.whereEqualTo(IMEI,helpUtils.getDeviceIDEqualsIMEI());
query.setLimit(1000);
query.findInBackground(新FindCallback<&的parseObject GT;()
{
@覆盖
公共无效完成(列表<&的parseObject GT; DataList控件,ParseException的E){}
});
你想用的DataList
的parseObject
的是你将收到一份关于什么完成
回调。
i have made this array column in parse.com dashboard.i am able to add values in the array from my app but m not able to get the array or list and using any function on it(even size() ) give null point exception on that line.
i have used many solutions but none worked.
my code where it is giving error.
real = (TextView) v.findViewById(R.id.realtext);
fake = (TextView) v.findViewById(R.id.faketext);
realbutton = (ImageButton) v.findViewById(R.id.realbutton);
fakebutton = (ImageButton) v.findViewById(R.id.fakebutton);
real.setText(String.valueOf(news.getRealvote()));
fake.setText(String.valueOf(news.getFake()));
fakebutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
news.setuserArray(news.getAuthor().getUsername());
List<ParseObject> a = news.getUserArray();
Toast.makeText(c, a.toString(), Toast.LENGTH_SHORT).show();//any thing with a.size() etc anything gives error
news.setFake();
news.saveInBackground();
fake.setText(String.valueOf(news.getFake()));
realbutton.setVisibility(View.GONE);
fakebutton.setVisibility(View.GONE);
}
});
here is my getUserArray() method
public List<ParseObject> getUserArray() {
return getList("users_rated");
}
the method to store data is working
public void setuserArray(String file) {
addUnique("users_rated", file);
}
i have tried a lot but no success.plss help me retrieving the array.
are you asking for list adapter??
public class Customnewslistview extends ParseQueryAdapter<News> {
Context c;
public Customnewslistview(Context context) {
super(context, "News");
c = context;
}
@Override
public View getItemView(final News news, View v, ViewGroup parent) {
if (v == null) {
final TextView real;
final TextView fake;
final ImageButton realbutton;
final ImageButton fakebutton;
final ProgressBar loader;
v = View.inflate(getContext(), R.layout.item_list_news_public, null);
loader = (ProgressBar) v.findViewById(R.id.eachnewsloder);
ParseImageView newsImage = (ParseImageView) v
.findViewById(R.id.icon);
ParseFile photoFile = news.getParseFile("photo");
if (photoFile != null) {
newsImage.setParseFile(photoFile);
newsImage.loadInBackground(new GetDataCallback() {
@Override
public void done(byte[] data, ParseException e) {
Log.d("done pic", data.toString());
loader.setVisibility(View.GONE);
}
});
} else {
loader.setVisibility(View.GONE);
newsImage.setBackgroundResource(R.drawable.image40);
}
TextView titleTextView = (TextView) v.findViewById(R.id.text1);
titleTextView.setText(news.getTitle());
// trying real fake buttons
real = (TextView) v.findViewById(R.id.realtext);
fake = (TextView) v.findViewById(R.id.faketext);
realbutton = (ImageButton) v.findViewById(R.id.realbutton);
fakebutton = (ImageButton) v.findViewById(R.id.fakebutton);
real.setText(String.valueOf(news.getRealvote()));
fake.setText(String.valueOf(news.getFake()));
realbutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
news.setuserArray(news.getAuthor().toString());
news.setRealvote();
news.saveInBackground();
real.setText(String.valueOf(news.getRealvote()));
Toast.makeText(getContext(), "No Cheating",
Toast.LENGTH_SHORT).show();
realbutton.setVisibility(View.GONE);
fakebutton.setVisibility(View.GONE);
}
});
fakebutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
news.setuserArray(news.getAuthor().getUsername());
List<ParseObject> a=null;
try {
a = news.fetchIfNeeded().getList("users_rated");
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Toast.makeText(c, a.toString(), Toast.LENGTH_SHORT).show();
news.setFake();
news.saveInBackground();
fake.setText(String.valueOf(news.getFake()));
realbutton.setVisibility(View.GONE);
fakebutton.setVisibility(View.GONE);
}
});
titleTextView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Dialog d = new Dialog(c);
d.setContentView(R.layout.publicnewsdialog);
d.setTitle("News");
TextView text = (TextView) d.findViewById(R.id.dialogtext);
text.setText(news.getTitle());
// parsing image
ParseImageView newsImage = (ParseImageView) d
.findViewById(R.id.dialogimage);
ParseFile photoFile = news.getParseFile("photo");
if (photoFile != null) {
newsImage.setParseFile(photoFile);
newsImage.loadInBackground(new GetDataCallback() {
@Override
public void done(byte[] data, ParseException e) {
Log.d("done pic", data.toString());
}
});
} else {
loader.setVisibility(View.GONE);
newsImage.setBackgroundResource(R.drawable.image40);
}
d.show();
}
});
}
return v;
}
}
This is the method I use to get a List
of a DB of TrackedLocation
objects:
ParseQuery<ParseObject> query = ParseQuery.getQuery("TrackedLocation");
query.whereEqualTo("imei", helpUtils.getDeviceIDEqualsIMEI());
query.setLimit(1000);
query.findInBackground(new FindCallback<ParseObject>()
{
@Override
public void done(List<ParseObject> dataList, ParseException e) {}
});
Do what you want with the dataList
of ParseObject
s you will receive on the done
callback.
