Pass reference of view to CustomView - android

I have one linear layout in that I have two views for an email address, one is Textview and another one is Edittext.
When there is empty or not proper email address then Textview's color should change to red,
if the user gets focus on edit text Textview's color should change to blue.
if the user lost focus on EditText then TextView's color should change to black.
To check how to achieve with customview, I have created a custom view of its parent view which is LinearLayout which is below
CustomLinearLayout.java file
public class CustomLinearLayout extends LinearLayout {
int editTextResourceId, textViewResourceId;
EditText editText;
TextView textView;
Context mContext;
public CustomLinearLayout(Context context) {
super(context);
mContext = context;
}
public CustomLinearLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomLinearLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
mContext = context;
inflate(context, R.layout.activity_register_account_new, this);
TypedArray a = context.getTheme().obtainStyledAttributes(attrs, R.styleable.MyTextView, defStyleAttr, 0);
editTextResourceId = a.getResourceId(R.styleable.MyTextView_supportedEditText, NO_ID);
textViewResourceId = a.getResourceId(R.styleable.MyTextView_supportedTextView, NO_ID);
a.recycle();
}
#Override
public void onAttachedToWindow() {
super.onAttachedToWindow();
if (editTextResourceId != 0 && textViewResourceId != 0) {
editText = (EditText)findViewById(editTextResourceId);
editText.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {}
#Override
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start,
int before, int count) {
if(s.length() != 0){
textView.setText(s);
}
}
});
}
}
}
activity_main.xml file looks like
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/grey"
android:orientation="vertical">
<mobile.android.view.CustomLinearLayout
style="#style/RegisterItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
custom:supportedEditText="#id/edUserName"
custom:supportedTextView="#id/tvUserName"
android:orientation="horizontal">
<TextView
android:id="#+id/tvUserName"
style="#style/RegisterTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/username" />
<EditText
android:id="#+id/edUserName"
style="#style/RegisterEditText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="#string/hint_username"
android:inputType="textPersonName" />
</mobile.android.view.CustomLinearLayout>
attris.xml file
<declare-styleable name="MyTextView">
<attr name="supportedEditText" />
<attr name="supportedTextView" />
</declare-styleable>
But whenever I debug code, it shows me 0 (resource id) instead of proper id or NO_ID.
Can anyone help me how to resolve this? thanks,


Try this code inside CustomLinearLayout.java :
private EditText findEditText() {
int i = 0;
for (; i < getChildCount(); i++) {
if (getChildAt(i) instanceof EditText) {
return (EditText) getChildAt(i);
}
}
return null;
}
private TextView findTextView() {
int i = 0;
for (; i < getChildCount(); i++) {
if (getChildAt(i) instanceof TextView) {
return (TextView) getChildAt(i);
}
}
return null;
}
#Override
public void onAttachedToWindow() {
super.onAttachedToWindow();
TextView textView = findTextView();
EditText editText = findEditText();
if (editText != null) {
editText.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {
}
#Override
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start,
int before, int count) {
if (s.length() != 0) {
if (textView != null) {
textView.setText(s);
}
}
}
});
}
}


I built one thing like you want and I call it : EditTextComponent
This is java source code for EditTextComponent:
public class EdittextComponent extends InputComponent {
protected TextView tvTitle;
protected EditText edtInput;
protected int mInputType = InputType.TYPE_CLASS_TEXT;
protected int mMaxLine = 1;
protected InputFilter[] mInputFilter;
protected boolean hasFirstChange = false;
protected TextView tvWarning;
protected int mIDLayout = R.layout.component_edittext;
protected boolean isAlwaysShowWarning = false;
#Override
public View createView() {
LayoutInflater inflater = LayoutInflater.from(mContext);
rootView = inflater.inflate(mIDLayout, null, false);
tvTitle = rootView.findViewById(R.id.tv_title);
if (Utils.validateString(mTitle)) {
tvTitle.setText(mTitle);
}
edtInput = rootView.findViewById(R.id.edt_input);
if (Utils.validateString(mPlaceHolder)) {
edtInput.setHint(mPlaceHolder);
}
edtInput.setInputType(mInputType);
edtInput.setMaxLines(mMaxLine);
if (null != mInputFilter && mInputFilter.length > 0) {
edtInput.setFilters(mInputFilter);
}
if (Utils.validateString(mValue)) {
edtInput.setText(mValue);
}
if(null != mValueSelected){
isCompleted = true;
String value = (String) mValueSelected;
if(Utils.validateString(value)) {
edtInput.setText(value);
}
}
edtInput.addTextChangedListener(new TextWatcher() {
#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 void afterTextChanged(Editable s) {
if (null != s) {
hasFirstChange = true;
checkChange(s.toString().trim());
}
}
});
tvWarning = rootView.findViewById(R.id.tv_warning);
return rootView;
}
protected void checkChange(String source) {
if (null != mValidator) {
boolean newState = mValidator.validate(source);
if (isCompleted != newState) {
notifyStateChanged(newState, source);
}
} else {
if (source.length() == 0) {
if (isCompleted) {
notifyStateChanged(false, source);
}
} else if (!isCompleted) {
notifyStateChanged(true, source);
}
}
if(isCompleted){
edtInput.setBackgroundResource(R.drawable.bg_input);
tvWarning.setVisibility(View.INVISIBLE);
}
else{
showWarning(true);
}
}
protected void notifyStateChanged(boolean is_complete, String source) {
isCompleted = is_complete;
if (null != mCallBack) {
mCallBack.onChanged(isCompleted, source);
}
}
public void updateValue(String value){

}
checkChange(value);
}
#Override
public boolean validate() {
if(!isVisible){
return true;
}
if (!isCompleted ) {
showWarning(false);
}
return isCompleted;
}
protected void showWarning(boolean isCallByItSelf) {
String message = "Cannot be empty";
if (null != mValidator) {
message = mValidator.getMessage();
}
if(null != tvWarning) {
tvWarning.setText(message);
tvWarning.setVisibility(View.VISIBLE);
}
if(null != edtInput) {
edtInput.setBackgroundResource(R.drawable.bg_input_warning);
}
}
#Override
public String getValue() {

#Override

}
public void setInputType(int inputType) {

BaseComponet.java

return rootView;
}
#Override
public int compareTo( BaseComponent otherComponent) {
if (null != otherComponent) {
return (otherComponent.getPosition() - getPosition());
}
return 0;
}
}
And this is how you can use EditTextComponent:
EdittextComponent lastNameComponent = new EdittextComponent();
lastNameComponent.setPlaceHolder("Enter last name");
lastNameComponent.setTitle("Last name");
lastNameComponent.setKey("lastname");
lastNameComponent.setCallBack(new InputCallBack() {
#Override
public void onChanged(boolean isSelected, Object data) {
checkComplete();
}
});
listInputComponents.add(lastNameComponent);
You can use this component to create email, last name, phonecode .... and add them to listInputComponents ( an array)
Then you can add them to a linearlaylout like this:
LinearLayout llBody = findViewById(...)
for(BaseComponent component: listInputComponents)
{ llBody.addView(component.createView()
}

I have updated code,

Just Override toString methods and return data that you want to display.
public class SearchResults {

public SearchResults(String suggetions, String suggetionId) {
this.suggetions = suggetions;
this.suggetionId = suggetionId;

}
public String getSuggetionId() {
return suggetionId;
}
public void setSuggetionId(String suggetionId) {
this.suggetionId = suggetionId;
}
#Override
public final String toString()
{
return suggetions;
}
}

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

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) {
}

clicking on calendar icon in the editext for the first time is not showing the datepicker dialog

Hai I have editext in my app where we can set the date of birth. in that editext I have a calendar icon. If we click on calendar icon it should open the datepicker dialog. But in my case if I click on calendar icon it is showing paste, clicpboard, selectall options in my editext instead of showing the date picker dialog and if we click on the calendar icon again for the second time it is opening the date picker dialog. How to make the datepicker dialog open for the first click on my calendar icon. I alreadt set setFocusable and setFocusableInTouchMode to false but no use. please help to fix the same.

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);
}
}

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 {
private int HomeItemID;
private String HomeItemRedName, HomeItemRedAge, HomeItemRedRecord, HomeItemRedHeight, HomeItemRedWeight,
HomeItemRedCity, HomeItemRedExp;
private String HomeItemBlueName, HomeItemBlueAge, HomeItemBlueRecord, HomeItemBlueHeight, HomeItemBlueWeight,
HomeItemBlueCity, HomeItemBlueExp;
public int getHomeItemID() {
return HomeItemID;
}
public void setHomeItemID(int ID) {

Compiling this, in my LogCat, I receive this error:

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()+"");
be.setText(homeItem.getHomeItemBlueExp()+"");
play.setOnClickListener(new View.OnClickListener() {
#Override

done.setOnClickListener(new View.OnClickListener() {
