Create one pojo class like
class student{
String id,
String name,
String age,
String titles
}
now replace below code
if(c.moveToFirst()) {
do {
titles.add(c.getString(id) + " \t " + c.getString(name) + " \t " + c.getString(age));
} while (c.moveToNext());
arrayAdapter.notifyDataSetChanged();
lst1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String tt = titles.get(position).toString();
Intent i = new Intent(getApplicationContext(),edit.class);
i.putExtra("age",tt);
startActivity(i);
}
});
with
ArrayList<student> stud = new ArrayList<student>();
if(c.moveToFirst()) {
do {
student stu = new student()
stu.id = c.getString(id);
stu.name = c.getString(name);
stu.age = c.getString(age);
//you need to add the Student object stu not the ArrayList Object stud
stud.add(stu);
titles.add(c.getString(id) + " \t " + c.getString(name) + " \t " + c.getString(age));
} while (c.moveToNext());
arrayAdapter.notifyDataSetChanged();
lst1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String tt = titles.get(position).toString();
student stu = stud.get(position);
Intent i = new Intent(getApplicationContext(),edit.class);
i.putExtra("age",stu.age);
startActivity(i);
}
});

You need to create a class for your custom items:
class Student{
String id;
String name;
String age;
String title;
public Student(String id, String name, String age)
{
this.id = id;
this.name = name;
this.age = age;
title = id + " \t" +name+" \t"+age;
}
}
//View.java:
if(c.moveToFirst()) {
do {
Student tmpStudent = new Student(c.getString(id), c.getString(name), c.getString(age));
titles.add(tmpStudent.title);
} while (c.moveToNext());
arrayAdapter.notifyDataSetChanged();
lst1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String studentString[] = titles.get(position).toString().Split(" \t");
Student tmpStringStudent = new Student(studentString[0], studentString[1], studentString[2]);
Intent i = new Intent(getApplicationContext(),edit.class);
i.putExtra("id",tmpStringStudent.id);
i.putExtra("name",tmpStringStudent.name);
i.putExtra("age",tmpStringStudent.age);
startActivity(i);
}
});
}
//Edit.java:
public class edit extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit);
EditText ageEditText = findViewById(R.id.age);
EditText idEditText = findViewById(R.id.id);
EditText nameEditText = findViewById(R.id.name);
Intent i = getIntent();
String id = i.getStringExtra("id").toString();
String name = i.getStringExtra("name").toString();
String age = i.getStringExtra("age").toString();
idEditText.setText(id);
nameEditText.setText(name);
ageEditText.setText(age);
}
}
I hope this helps.

Changing the textview to 2 decimal place in android recyclerview textview

I have a textview in a recyclerview which shows decimal money values saved in an sqlite database. But when I enter $10.00 into the database the recyclerview textview shows it as $10 instead of $10.00. How do I fix this?
This is my layout for the recyclerview:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/pound"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:paddingBottom="5dp"
android:paddingTop="5dp"
android:paddingStart="8dp"
android:text="£"
android:textSize="20sp"
android:textColor="#color/fab2_color"/>
<TextView
android:id="#+id/favourite_textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginRight="8dp"
android:layout_weight="1"
android:maxLength="9"
android:paddingBottom="5dp"
android:paddingTop="5dp"
android:textSize="20sp"
android:textColor="#color/fab2_color"
/>
</LinearLayout>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_marginEnd="5dp"
android:layout_marginRight="5dp"
android:color="#ffffff" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingTop="30dp">
<TextView
android:id="#+id/category_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="2"
android:maxLines="1"
android:paddingBottom="5dp"
android:paddingTop="5dp"
android:paddingStart="8dp"/>
<TextView
android:id="#+id/verse_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginRight="8dp"
android:layout_weight="1"
android:gravity="end"
android:maxLines="1"
android:paddingBottom="5dp"
android:paddingTop="5dp" />
</LinearLayout>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_marginEnd="5dp"
android:layout_marginRight="5dp"
android:color="#ffffff" />
</android.support.v7.widget.CardView>
Here is where I insert the values into the database:
public void AddData(){
FloatingActionButton fab2 = (FloatingActionButton) findViewById(R.id.fab_tick_income);
fab2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
formatter = new DecimalFormat("0.00");
RawincomeValue = editAmountincome.getRawValue();
FormatedincomeVal = (double) RawincomeValue/100;
if (FormatedincomeVal > 0){
isAmountInserted = true;
}
else{
isAmountInserted = false;
}
noteCheck = editNotesincome.getText().toString().trim();
if(noteCheck.isEmpty())
{
noteCheck = noteCheck.replace("", "No Note Inserted");
}
else
{
//EditText is not empty
}
if(isCategoryInserted && isDateInserted && isAmountInserted && isAccountInserted) {
myDbincome.insertincomeData(
FormatedincomeVal,
editDateincome.getText().toString(),
noteCheck,
category,
account);
Toast.makeText(add_income.this,"Income Registered",Toast.LENGTH_LONG).show();
Intent intent=new Intent(add_income.this, MainActivity.class);
startActivity(intent);
}
adapter viewholder as per request:
public class IncomeAdapter extends RecyclerView.Adapter<IncomeAdapter.ViewHolder> {
private final ArrayList<String> dataSet;
private final ArrayList<String> dataSet2;
private final ArrayList<String> dataSet3;
private ItemClickListener clickListener;
DecimalFormat formatter = new DecimalFormat("0.00");
String myListPreference;
Context ctx;
class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
final TextView pound;
final TextView mTextView;
final TextView textView;
final TextView categoryText;
final CardView cardView;
ViewHolder(View v) {
super(v);
SharedPreferences sharedPreferences = android.support.v7.preference.PreferenceManager.getDefaultSharedPreferences(ctx);
myListPreference = sharedPreferences.getString("CurrencyType", "£");
pound = (TextView) v.findViewById(R.id.pound);
mTextView = (TextView) v.findViewById(R.id.favourite_textView);
categoryText = (TextView) v.findViewById(R.id.category_text);
textView = (TextView) v.findViewById(R.id.verse_text);
cardView = (CardView) v.findViewById(R.id.cardview);
pound.setText(""+ myListPreference);
v.setOnClickListener(this);
}
#Override
public void onClick(View view) {
if (clickListener != null) clickListener.onClick(view, getAdapterPosition());
}
}
public IncomeAdapter(ArrayList<String> myDataset, ArrayList<String> myDataSet2, ArrayList<String> myDataset3, Context ctx) {
this.dataSet = myDataset;
this.dataSet2 = myDataSet2;
this.dataSet3 = myDataset3;
this.ctx = ctx;
}
How I put the information into the recyclerview:
private void populateListView() {
Log.d(TAG, "populateListView: Displaying data in the ListView.");
ArrayList<String> arrayList = new ArrayList<>();
ArrayList<String> arrayList2 = new ArrayList<>();
ArrayList<String> arrayList3 = new ArrayList<>();
IncomeAdapter incomeAdapter = new IncomeAdapter(arrayList,arrayList2,arrayList3, getContext());
mListView.setAdapter(incomeAdapter);
incomeAdapter.setClickListener(this);
incomedata = mDatabaseHelper.getincomeData();
if(incomedata.moveToFirst()){
do {
arrayList.add(incomedata.getString(incomedata.getColumnIndex(DatabaseHelper.INCOME_AMOUNT)));
arrayList2.add(incomedata.getString(incomedata.getColumnIndex(DatabaseHelper.INCOME_DATE)));
arrayList3.add(incomedata.getString(incomedata.getColumnIndex(DatabaseHelper.INCOME_CATEGORY)));
}
while (incomedata.moveToNext());
}
incomeAdapter.notifyDataSetChanged();
}

textview.setText( String.format( "Value
of a: %.2f", a ) );

Circular imageview dissappears in listview after fling

Im generating a feed full of images (similar to instagram post) using Glide for loading images and user's profile picture. After i get the data from server, i load the Url's of images inside the listitem. Initally All items are being loaded properly.

When loading multiple images there is always caching problem when using Async Tasks. I recommend an open source library Picasso. It will load the images and cache it. After that most probably, your fast scroll problem will solve.
The cause can also be the size of the images being received. Picasso has methods by which you can resize the image before putting it onto the image view

try with this modified getView

I know this is probably really simple but looking online doesn't answer it...
why does this crash upon getting to here?:

Edit*
Search() is an onClick button in ps.xml while the textview are in list.xml

Inside your onCreate() method:
change from setContentView(R.layout.ps); to setContentView(R.layout.list); because you are using list.xml as your main layout.
and delete this line setContentView(R.layout.list); inside your Search() method:
public void Search(View view) {
int clist = -2;
String oID = "";
String oName = "";
String oWorld = "";
// Delete this line setContentView(R.layout.list);
while (clist != -1)
{
oID = tID.getText().toString();
tID.setText(oID+"ddf"+"\n");
oName = tName.getText().toString();
clist = -1;
}
}

Android: archiving items in listview

I'm having a listview in which I'm displaying the text items. I want to display a checkbox along with the text for two type of actions to be performed. one is when the user click on the list item it should take to another activity and another is the user can select the checkbox of the list item and can move the items to some groups. As similar to that we do in the gmail inbox. how can i do it ? Any help ?
Here I attach my code.
keywords.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/keywordlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background_gradient"
android:orientation="vertical"
>
<LinearLayout
android:id="#+id/category_title_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#fff"
>
<TextView
android:id="#+id/category_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=""
android:textColor="#000"
android:textStyle="italic"
android:typeface="sans"
android:gravity="center"
/>
</LinearLayout>
<ListView
android:id="#+id/keywordslist"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background_gradient"
>
</ListView>
</LinearLayout>
The xml file used for displaying list items layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

and my java code for the activity
package com.sample.epiphron;
public class KeywordsList extends Activity {
TextView category_title;
ListView keywords_list ;
String categoryid, categoryname;
private ArrayList<KeywordDetails> listItems = new ArrayList<KeywordDetails>();
#Override

super.onCreate(savedInstanceState);

Bundle extras = getIntent().getExtras();

categoryname = extras.getString("category_name");
category_title = (TextView) findViewById(R.id.category_title);
category_title.setText(""+categoryname+"- Keywords");
keywords_list = (ListView) findViewById(R.id.keywordslist);
drawList(LoginScreen.user_credential, categoryid);
//Toast.makeText(this, chkbx.toString(), Toast.LENGTH_SHORT).show();
keywords_list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
TextView txtv1 = (TextView) arg1.findViewById(R.id.key_id);
Toast.makeText(KeywordsList.this, txtv1.getText(), Toast.LENGTH_LONG).show();
}
});
}
public void drawList(String userid, String cat_id){
WebServiceCall res = new WebServiceCall();
SoapObject result = res.fetchKeyword(userid, cat_id);
ArrayList<String> al = new ArrayList<String>();
for (int i = 0; i<result.getPropertyCount(); i++){
SoapObject obj = (SoapObject) result.getProperty(i);
al.add((String) obj.getProperty("keywordname"));
KeywordDetails object = new KeywordDetails(Integer.parseInt(obj.getProperty("keywordid").toString()), obj.getProperty("keywordname").toString());
listItems.add(object);
}
for ( int j = 0; j < result.getPropertyCount(); j++ ) {
}
keywords_list.setAdapter(new ListItemsAdapter(listItems));
}
public class KeywordDetails{
private int keyword_id;
private String keyword_name;
public KeywordDetails(int key_id, String key_name){
this.keyword_id = key_id;
this.keyword_name = key_name;
}
public int getId(){
return this.keyword_id;
}
public String getName(){
return this.keyword_name;
}
//...
}
private class ListItemsAdapter extends ArrayAdapter<KeywordDetails> {
ArrayList<KeywordDetails> obj = null;
KeywordDetails keyworddtls = null;
public ListItemsAdapter(ArrayList<KeywordDetails> items) {
super(KeywordsList.this, android.R.layout.simple_list_item_1, items);
this.obj = items;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = getLayoutInflater();
convertView = inflater.inflate(R.layout.keyword_list_item, null);
final TextView text1 = (TextView) convertView.findViewById(R.id.key_id);
TextView text2 = (TextView) convertView.findViewById(R.id.key_name);
CheckBox chkbx = (CheckBox) convertView.findViewById(R.id.chk_box);
keyworddtls = obj.get(position);
text1.setText(Integer.toString(keyworddtls.getId()));
text2.setText(keyworddtls.getName());
chkbx.setVisibility(View.VISIBLE);
return convertView;
}
}
}

Add the CheckBox in the xml where is your <ListView > or in the xml which you use as item layout. Then in the getView() instantiate the CheckBox along the TextView. Implement listview.setOnItemClickListener() and based on which item was clicked (position) you start the activity [matter of logic] For the grouped of check items you can use getCheckedItemPositions(). I hope this will give you fire up idea.
