EditText in RecycleView sum all value from editText

EditText in RecycleView sum all value from editText - android

I am new in android and I have two activities and each activity contains a recycled view. Now when I clicked on my first activity item, then this will go to new activity and get the result from second recycle view and I need to show this in my first recycle view, I have done all this, but am not able to get the value from second recycled view. How can i do this?
This is my some part of my code
holder.mGroup.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent individual = new Intent(Context, `enter code here`A.class);`enter code here`
individual.putExtra(Constants.REQ_TYPE,mCollectionDate);
individual.putExtra(Constants.GROUP_POSITION,position);
individual.putExtra(Constants.CENTER_POSITION,Selectedposition);
individual.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
((Activity)mContext).startActivityForResult(individual, 200);
//mContext.startActivity(individual);
}
});
}
Thank you!

You have to set a result on the second activity before get back:
Intent intent = new Intent();
intent.putExtra("parameter", response);
setResult(Activity.RESULT_OK, intent);
finish();
And then treat on the first activity:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if ( requestCode == 200 && resultCode == Activity.RESULT_OK ) {
<<YOUR PARAMETER>> = data.getExtra("parameter");
}
}

Two way binding on custom view

I have a componed view in android contains several textViews and one EditText. I defined an attribute for my custom view called text and getText, setText methods. Now I want to add a 2-way data binding for my custom view in a way its bind to inner edit text so if my data gets updated edit text should be updated as well (that's works now) and when my edit text gets updated my data should be updated as well.
My binding class looks like this
#InverseBindingMethods({
#InverseBindingMethod(type = ErrorInputLayout.class, attribute = "text"),
})
public class ErrorInputBinding {
#BindingAdapter(value = "text")
public static void setListener(ErrorInputLayout errorInputLayout, final InverseBindingListener textAttrChanged) {
if (textAttrChanged != null) {
errorInputLayout.getInputET().addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void afterTextChanged(Editable editable) {
textAttrChanged.onChange();
}
});
}
}
}
I tried to bind text with the code below. userInfo is an observable class.
<ir.avalinejad.pasargadinsurance.component.ErrorInputLayout
android:id="#+id/one_first_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:title="#string/first_name"
app:text="#={vm.userInfo.firstName}"
/>
When I run the project I get this error
Error:(20, 13) Could not find event 'textAttrChanged' on View type 'ir.avalinejad.pasargadinsurance.component.ErrorInputLayout'
And my custom view looks like this
public class ErrorInputLayout extends LinearLayoutCompat implements TextWatcher {
protected EditText inputET;
protected TextView errorTV;
protected TextView titleTV;
protected TextView descriptionTV;
private int defaultGravity;
private String title;
private String description;

} finally {

}

}
}

return text;
}

}
#Override

errorTV.setText(validationMap.get(validation));
errorTV.setVisibility(VISIBLE);
isValidObservable.onNext(false);
return;
}
}
isValidObservable.onNext(true);
}
}

After hours of debugging, I found the solution. I changed my Binding class like this.
#InverseBindingMethods({
#InverseBindingMethod(type = ErrorInputLayout.class, attribute = "text"),
})
public class ErrorInputBinding {
#BindingAdapter(value = "textAttrChanged")
public static void setListener(ErrorInputLayout errorInputLayout, final InverseBindingListener textAttrChanged) {
if (textAttrChanged != null) {
errorInputLayout.getInputET().addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void afterTextChanged(Editable editable) {
textAttrChanged.onChange();
}
});
}
}
#BindingAdapter("text")
public static void setText(ErrorInputLayout view, String value) {
if(value != null && !value.equals(view.getText()))
view.setText(value);
}
#InverseBindingAdapter(attribute = "text")
public static String getText(ErrorInputLayout errorInputLayout) {
return errorInputLayout.getText();
}
First, I added AttrChanged after the text like this #BindingAdapter(value = "textAttrChanged") which is the default name for the listener and then I added getter and setter methods here as well.

event = "android:textAttrChanged" works for me:
object DataBindingUtil {
#BindingAdapter("emptyIfZeroText") //replace "android:text" on EditText
#JvmStatic
fun setText(editText: EditText, text: String?) {
if (text == "0" || text == "0.0") editText.setText("") else editText.setText(text)
}
#InverseBindingAdapter(attribute = "emptyIfZeroText", event = "android:textAttrChanged")
#JvmStatic
fun getText(editText: EditText): String {
return editText.text.toString()
}
}

you need add one more function
#BindingAdapter("app:textAttrChanged")
fun ErrorInputLayout.bindTextAttrChanged(listener: InverseBindingListener) {
}

You need context in order to call showDialog() from Fragment. Try calling
getActivity().showDialog(DIALOG_EXIT);

Use of different TextWatcher-implementations inside RecyclerView.Adapter

Currently I use a RecyclerView to represent a dynamically configuration list form.
Every configuration item (entry at RecyclerView list) contains one EditText item.
To avoid wrong user input (some fields allow only integer, others only one digit after comma), I've implemented two different TextWatcher-filters which correct illegal input ("DecimalFilterDigitsAfterComma" and "DecimalFilterInteger").
My RecyclerView has 16 configuration items in total, but can only display maximum 8 at one time.
My problem is that the TextWatchers are assigned to specific Items (Integers and Decimal-Point TextEdit). But when I'm scrolling a bit, they change their order, so that Decimal- and Integer-Filters get swapped.
The TextWatcher items will be created inside the ConfigurationAdapter which is a RecyclerView.Adapter. I've event managed that the TextWatcher is only created once for each entry by using the mListConfigInit which is a boolean flag list for the items.
ConfigurationAdapter.java:
public class ConfigurationAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
/*
...
*/
private List<ConfigItem> mConfiguration = new ArrayList<>();
// make sure that DecimalFilter is only created once for each item
private List<Boolean> mListConfigInit = new ArrayList<>();
public ConfigurationAdapter() {
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(
R.layout.listitem_configuration,
parent,
false);
final ConfigurationViewHolder vh = new ConfigurationViewHolder(v);
/*
...
*/
return vh;
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
final ConfigurationViewHolder vh = (ConfigurationViewHolder) holder;
ConfigItem config = mConfiguration.get(position);
if(config.ShowValueAsFloat()) {
vh.SetTextWatcherType(ConfigurationViewHolder.TextWatcherType.type_FloatActive);
} else {
vh.SetTextWatcherType(ConfigurationViewHolder.TextWatcherType.type_IntActive);
}
// set name and unit
vh.mName.setText(config.mName);
vh.mUnit.setText(config.mUnit);
/*
...
*/
}
#Override
public int getItemCount() {
return mConfiguration.size();
}
public void addConfigItem(ConfigItem item) {
mConfiguration.add(item);
mListConfigInit.add(new Boolean(false));
notifyItemInserted(mConfiguration.size() - 1);
//notifyDataSetChanged();
}
/*
...
*/
}
ConfigurationViewHolder.java (changed according to pskink-comments):
public final class ConfigurationViewHolder extends RecyclerView.ViewHolder implements TextWatcher {
public TextView mName;
public CheckBox mCheckbox;
public SeekBar mSeekbar;
public EditText mValueEditText;
public TextView mUnit;
private List<TextWatcher> mListTextWatchers = new ArrayList<>();
public enum TextWatcherType {
type_FloatActive(0),
type_IntActive(1);
private int mValue;
TextWatcherType(int value) {
mValue = value;
}
int val() { return mValue; }
}
private TextWatcherType mTextWatcherType = TextWatcherType.type_FloatActive;
public ConfigurationViewHolder(View itemView) {
super(itemView);
mName = (TextView) itemView.findViewById(R.id.textView_configuration_name);
mValueEditText = (EditText) itemView.findViewById(R.id.editText_configuration_value);
mUnit = (TextView) itemView.findViewById(R.id.textView_configuration_unit);
mCheckbox = (CheckBox) itemView.findViewById(R.id.checkbox_configuration);
mSeekbar = (SeekBar) itemView.findViewById(R.id.seekBar_configuration);
mListTextWatchers.add(0, new DecimalFilterDigitsAfterComma(mValueEditText, 1));
mListTextWatchers.add(1, new DecimalFilterInteger(mValueEditText));
mValueEditText.addTextChangedListener(this);
}
public void SetTextWatcherType(TextWatcherType textWatcherType) {
mTextWatcherType = textWatcherType;
}
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {}
#Override
public void afterTextChanged(Editable editable) {
mListTextWatchers.get(mTextWatcherType.val()).afterTextChanged(editable);
}
}
DecimalFilterInteger.java
public class DecimalFilterInteger implements TextWatcher {
private final static String TAG = ConfigurationAdapter.class.getSimpleName();
private final EditText mEditText;
private String mLastTextValue = new String("");
public DecimalFilterInteger(EditText editText) {
this.mEditText = editText;
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public synchronized void afterTextChanged(final Editable text) {
String strInput = text.toString().trim();
if(strInput.isEmpty()) {
return;
}
if(strInput.equals(mLastTextValue)) { // return when same value as last time to avoid endless loop
return;
}
if ((strInput.charAt(0) == '.')) { // handle dot at beginning
strInput = "";
}
if(strInput.contains(".")){ // cut trailing comma
String numberBeforeDecimal = strInput.split("\\.")[0];
strInput = numberBeforeDecimal;
}
mEditText.removeTextChangedListener(this);
mEditText.getText().clear(); // do not use setText here to avoid changing the keyboard
mEditText.append(strInput); // back to default (e. g. from 123-mode to abc-mode),
// see: http://stackoverflow.com/questions/26365808/edittext-settext-changes-the-keyboard-type-to-default-from-123-to-abc
mLastTextValue = mEditText.getText().toString();
mEditText.setSelection(mEditText.getText().toString().trim().length());
mEditText.addTextChangedListener(this);
}
}
Many thanks in advance for your help!

The cause of the swap/switching behaviour of the two different TextWatcher-implementations inside the RecyclerView was that I called removeTextChangedListenerand addTextChangedListenerinside their afterTextChanged-methods to avoid retriggering of the afterTextChanged-method.
The best way to avoid retriggering is a simple check if the text changed since the last call:
public class DecimalFilterInteger implements TextWatcher {
private final static String TAG = ConfigurationAdapter.class.getSimpleName();
private final EditText mEditText;
private String mLastTextValue = new String("");
// ...
#Override
public synchronized void afterTextChanged(final Editable text) {
String strInput = text.toString().trim();
if(strInput.isEmpty()) {
return;
}
if(strInput.equals(mLastTextValue)) { // return when same value as last time to avoid endless loop
return;
}
if ((strInput.charAt(0) == '.')) { // handle dot at beginning
strInput = "";
}
if(strInput.contains(".")){ // cut trailing comma
String numberBeforeDecimal = strInput.split("\\.")[0];
strInput = numberBeforeDecimal;
}
//mEditText.removeTextChangedListener(this); // CAUSE OF SWAP-ERROR !!!
mEditText.getText().clear(); // do not use setText here to avoid changing the keyboard
mEditText.append(strInput); // back to default (e. g. from 123-mode to abc-mode),
// see: http://stackoverflow.com/questions/26365808/edittext-settext-changes-the-keyboard-type-to-default-from-123-to-abc
mLastTextValue = mEditText.getText().toString();
mEditText.setSelection(mEditText.getText().toString().trim().length());
//mEditText.addTextChangedListener(this); // CAUSE OF SWAP-ERROR !!!
}
}

Add numbers from EditTexts

I've created an Activity where I've got an "Add subject" button. When I press it, it creates an item in a ListView, which is formed by an EditText where the user enters a number.
What I want to do is to add the numbers inside the EditTexts of each item created, depending if the user has created 3, 4, 5, etc. items in the ListView, via button.
Here is the code of the Activity:
public class PersActivity extends Activity {
Button start, calcaverage1;
private SubjectAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.subject_list_view);
setupListViewAdapter();
setupAddMarkButton();
// Accept button
Button acceptbn= (Button)findViewById(R.id.start1);
acceptbn.setOnClickListener(new OnClickListener()
{ public void onClick(View v)
{
Intent intent = new Intent(PersActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
});
}
public void removeClick(View v) {
Mark itemToRemove = (Mark)v.getTag();
adapter.remove(itemToRemove);
}
private void setupListViewAdapter() {
adapter = new SubjectAdapter(PersActivity.this, R.layout.subject_list_item, new ArrayList<Mark>());
ListView atomPaysListView = (ListView)findViewById(R.id.subject_list_item);
atomPaysListView.setAdapter(adapter);
}
private void setupAddMarkButton() {
findViewById(R.id.addsubject).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
adapter.insert(new Mark("", 0), 0);
}
});
}
}
Here is the code of the adapter:
public class SubjectAdapter extends ArrayAdapter<Mark> {
protected static final String LOG_TAG = SubjectAdapter.class.getSimpleName();
private List<Mark> items;
private int layoutResourceId;
private Context context;
public SubjectAdapter(Context context, int layoutResourceId, List<Mark> items) {
super(context, layoutResourceId, items);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.items = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
MarkHolder holder = null;
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new MarkHolder();
holder.Mark = items.get(position);
holder.removePaymentButton = (ImageButton)row.findViewById(R.id.remove);
holder.removePaymentButton.setTag(holder.Mark);
holder.name = (TextView)row.findViewById(R.id.subjectname);
setNameTextChangeListener(holder);
holder.value = (TextView)row.findViewById(R.id.subjectmark);
setValueTextListeners(holder);
row.setTag(holder);
setupItem(holder);
return row;
}
private void setupItem(MarkHolder holder) {
holder.name.setText(holder.Mark.getName());
holder.value.setText(String.valueOf(holder.Mark.getValue()));
}
public static class MarkHolder {
Mark Mark;
TextView name;
TextView value;
ImageButton removePaymentButton;
}
private void setNameTextChangeListener(final MarkHolder holder) {
holder.name.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
holder.Mark.setName(s.toString());
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) { }
#Override
public void afterTextChanged(Editable s) { }
});
}
private void setValueTextListeners(final MarkHolder holder) {
holder.value.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
try{
holder.Mark.setValue(Double.parseDouble(s.toString()));
}catch (NumberFormatException e) {
Log.e(LOG_TAG, "error reading double value: " + s.toString());
}
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) { }
#Override
public void afterTextChanged(Editable s) { }
});
}
}
I've implemented serializable to pass data through the adapter:
public class Mark implements Serializable {
private static final long serialVersionUID = -5435670920302756945L;
private String name = "";
private double value = 0;
public Mark(String name, double value) {
this.setName(name);
this.setValue(value);
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getValue() {
return value;
}
public void setValue(double value) {
this.value = value;
}
}
Hope there's a solution. Thanks!

Here is how you would do it
addNumberFromText()
{
int total=0;
for(int i=0;i<listView.getChildCount();i++)
{
View wantedView = listView.getChildAt(i);
EditText edtText=view.findViewById(R.id.specificEditTextId);
//not checking wheter integer valid or not, Please do so
int value=Integer.parseInt(edtText.toString());
total+=value;
}
Log.d(TAG,"total sum is "+total);
}
update your activity from following code
public class PersActivity extends Activity
{
Button start, calcaverage1;
private SubjectAdapter adapter;
ListView atomPaysListView;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.subject_list_view);
atomPaysListView = (ListView)findViewById(R.id.subject_list_item);
setupListViewAdapter();
setupAddMarkButton();
// Accept button
Button acceptbn= (Button)findViewById(R.id.start1);
acceptbn.setOnClickListener(new OnClickListener()
{ public void onClick(View v)
{
Intent intent = new Intent(PersActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
});
}
public void removeClick(View v) {
Mark itemToRemove = (Mark)v.getTag();
adapter.remove(itemToRemove);
}
private void setupListViewAdapter() {
adapter = new SubjectAdapter(PersActivity.this, R.layout.subject_list_item, new ArrayList<Mark>());
atomPaysListView.setAdapter(adapter);
}
private void setupAddMarkButton() {
findViewById(R.id.addsubject).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
adapter.insert(new Mark("", 0), 0);
}
});
}
addNumberFromText()
{
double total=0;
for(int i=0;i<atomPaysListView.getChildCount();i++)
{
View wantedView = atomPaysListView.getChildAt(i);
/*
// if edit text
EditText edt=(EditText)view.findViewById(R.id.editText);
//not checking wheter valid or not, Please do so
double value=Double.parseDouble(edt.toString());
*/
//you say edittext, but its a textview or so it seems
TextView txv=(TextView)view.findViewById(R.id.subjectmark);
//not checking wheter valid or not, Please do so
double value=Double.parseDouble(txv.toString());
total+=value;
}
Log.d(TAG,"total sum is "+total);
}
}

Setting text to a custom dialog class

The LogCat is point to my DialogClass on the line
rn.setText(redName);
I have never set the text to a custom built dialog, so please explain what I am doing wrong.
EDIT DUE TO blackbelt This is how I tried to do a class member. If it is not obvious by my reputation, I am a beginner so please explain a better way to do this:
Changed this in my activity that calls for the dialog
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
HomeItem homeItem = (HomeItem) adapter.getItem(position);
DialogClass dialogClass = new DialogClass(homeItem);
dialogClass.show();
}
});
Changed this in my DialogClass
public DialogClass(HomeItem context) {
super(context);
this.hi = context;
}
Then in my onCreate of my DialogClass:
rn.setText(hi.getHomeItemRedName());
bn.setText(hi.getHomeItemBlueName());
Because I had to use Context of HomeItem, or whatever I did I have to make my HomeItem class extend Context. I had to #Override about 80 methods:
public class HomeItem extends Context {

Still getting NullPointerException on
rn.setText(homeItem.getHomeItemRedName()+"");

setDialog is called before the Dialog's onCreate . Instead of passing all the Strings to setDialog you can pass a HomeItem reference and you can keep it as class member. Inside the onCreate, after setContentView you can perform all the findViewById and set the text accordingly
Edit
public class DialogClass extends Dialog implements View.OnClickListener {
public Activity c;
public Dialog d;
public Button yes, no;
public TextView rn, ra, rr, rh, rw, rc, re, bn, ba, br, bh, bw, bc, be;
private HomeItem homeItem;
public void setDialog(HomeItem homeItem){
this.homeItem = homeItem;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.custom_dialog);
yes = (Button) findViewById(R.id.bPlay);
no = (Button) findViewById(R.id.bDone);
yes.setOnClickListener(this);
no.setOnClickListener(this);
rn = (TextView) findViewById(R.id.tvRName);
ra = (TextView) findViewById(R.id.tvRAge);
rr = (TextView) findViewById(R.id.tvRRecord);
rh = (TextView) findViewById(R.id.tvRHeight);
rw = (TextView) findViewById(R.id.tvRWeight);
rc = (TextView) findViewById(R.id.tvRCity);
re = (TextView) findViewById(R.id.tvRExp);
bn = (TextView) findViewById(R.id.tvBName);
ba = (TextView) findViewById(R.id.tvBAge);
br = (TextView) findViewById(R.id.tvBRecord);
bh = (TextView) findViewById(R.id.tvBHeight);
bw = (TextView) findViewById(R.id.tvBWeight);
bc = (TextView) findViewById(R.id.tvBCity);
be = (TextView) findViewById(R.id.tvBExp);
rn.setText(homeItem.getHomeItemRedName());
// the rest of your code
}
// other code
}

This was actually really simple. I just ditched the Dialog class, and did it all here in my onClick.
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
HomeItem homeItem = (HomeItem) adapter.getItem(position);
final Dialog dialog = new Dialog(databaseFightCard.this);
Window window = dialog.getWindow();
window.setGravity(Gravity.CENTER);
window.requestFeature(window.FEATURE_NO_TITLE);
LayoutInflater inflater = (LayoutInflater) databaseFightCard.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout relative = (RelativeLayout) inflater.inflate(R.layout.custom_dialog, null, false);
dialog.setContentView(relative);
Button play = (Button) relative.findViewById(R.id.bPlay);
Button done = (Button) relative.findViewById(R.id.bDone);
TextView rn = (TextView) relative.findViewById(R.id.tvRName);
TextView ra = (TextView) relative.findViewById(R.id.tvRAge);
TextView rr = (TextView) relative.findViewById(R.id.tvRRecord);
TextView rh = (TextView) relative.findViewById(R.id.tvRHeight);
TextView rw = (TextView) relative.findViewById(R.id.tvRWeight);
TextView rc = (TextView) relative.findViewById(R.id.tvRCity);
TextView re = (TextView) relative.findViewById(R.id.tvRExp);
TextView bn = (TextView) relative.findViewById(R.id.tvBName);
TextView ba = (TextView) relative.findViewById(R.id.tvBAge);
TextView br = (TextView) relative.findViewById(R.id.tvBRecord);
TextView bh = (TextView) relative.findViewById(R.id.tvBHeight);
TextView bw = (TextView) relative.findViewById(R.id.tvBWeight);
TextView bc = (TextView) relative.findViewById(R.id.tvBCity);
TextView be = (TextView) relative.findViewById(R.id.tvBExp);
rn.setText(homeItem.getHomeItemRedName()+"");
ra.setText(homeItem.getHomeItemRedAge()+"");
rr.setText(homeItem.getHomeItemRedRecord()+"");
rh.setText(homeItem.getHomeItemRedHeight()+"");
rw.setText(homeItem.getHomeItemRedWeight()+"");
rc.setText(homeItem.getHomeItemRedCity()+"");
re.setText(homeItem.getHomeItemRedExp()+"");
bn.setText(homeItem.getHomeItemBlueName()+"");
ba.setText(homeItem.getHomeItemBlueAge()+"");
br.setText(homeItem.getHomeItemBlueRecord()+"");
bh.setText(homeItem.getHomeItemBlueHeight()+"");
bw.setText(homeItem.getHomeItemBlueWeight()+"");
bc.setText(homeItem.getHomeItemBlueCity()+"");
