ListView order get's mixed up when scrolling

I am developing an Android application and I am facing a seemingly well-known problem (I found a lot of similar questions but no answer works for me).
I use a ListView that displays an EditText and 2 TextView by adding an item in an ArrayList each time a user presses the button enter. However when I scroll the ListView the order of the elements changes and I can not fix this problem. I understand that the problem comes from the GetView which is recharged each time and therefore, on the view each item changes position but I do not know how to adjust it.
Thanks for your help.
I have already tried to overload the getViewTypeCount () and getItemViewType functions, I also tried to remove the maximum action in the (if convertView == null) but nothing has fixed my problem.

How to Store EditText Into ListView Item With Buttons

I am just starting with android, so I don't have much to show of what I have so far...
I am trying to make a to-do list. I have seen tutorials on how to do this with a menu for input and have the tasks displayed in a ListView, however I would like the user to input the task into an EditText instead. I was using this (which doesn't use a ListView) to just have a button click make a new TextView underneath the EditText, however I couldn't add buttons next to the TextView which would remove it (when the user finishes a task).
Using a ListView seems much easier for this, but how can I have the EditText input go to a ListView with all the tasks and buttons to remove them (permanently, not just set visibility to 0)? I would also like the tasks to be stored, so the user can close the app and return with the tasks still there.
Any ideas? I haven't made much progress.

I recommend you to use RecyclerView instead of Listview. compile this in your Gradle
compile 'com.levelupstudio:expandable-recyclerview:1.0.1'
Here is the mainActivity.java
public class MainActivity extends ActionBarActivity implements
RecyclerViewAdapter.OnItemClickListener{
private RecyclerView myRecyclerView;
private LinearLayoutManager linearLayoutManager;
private RecyclerViewAdapter myRecyclerViewAdapter;
EditText nameField;
Button btnAdd;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myRecyclerView = (RecyclerView)findViewById(R.id.myrecyclerview);
linearLayoutManager =
new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
/*
linearLayoutManager =
new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
*/
myRecyclerViewAdapter = new RecyclerViewAdapter(this);
myRecyclerViewAdapter.setOnItemClickListener(this);
myRecyclerView.setAdapter(myRecyclerViewAdapter);
myRecyclerView.setLayoutManager(linearLayoutManager);
nameField = (EditText)findViewById(R.id.namefield);
btnAdd = (Button)findViewById(R.id.addbutton);
btnAdd.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
String newName = nameField.getText().toString();
Context context= getApplicationContext();
myRecyclerViewAdapter.add(0,newName);
Toast.makeText(context,"You added" +newName.toUpperCase()+ "in your view",Toast.LENGTH_LONG).show();
}
});
}
#Override
public void onItemClick(RecyclerViewAdapter.ItemHolder item, int position) {
Toast.makeText(this,
"Remove " + position + " : " + item.getItemName(),
Toast.LENGTH_SHORT).show();
}}
And AdapterClass for Recycler
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.List;
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ItemHolder> {
private List<String> itemsName;
private OnItemClickListener onItemClickListener;
private LayoutInflater layoutInflater;
public RecyclerViewAdapter(Context context){
layoutInflater = LayoutInflater.from(context);
itemsName = new ArrayList<String>();
}
#Override
public RecyclerViewAdapter.ItemHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = layoutInflater.inflate(R.layout.list_item, parent, false);
return new ItemHolder(itemView, this);
}
#Override
public void onBindViewHolder(RecyclerViewAdapter.ItemHolder holder, int position) {
holder.setItemName(itemsName.get(position));
}
#Override
public int getItemCount() {
return itemsName.size();
}
public void setOnItemClickListener(OnItemClickListener listener){
onItemClickListener = listener;
}
public OnItemClickListener getOnItemClickListener(){
return onItemClickListener;
}
public interface OnItemClickListener{
public void onItemClick(ItemHolder item, int position);
}
public void add(int location, String iName){
itemsName.add(location, iName);
notifyItemInserted(location);
}
public static class ItemHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
private RecyclerViewAdapter parent;
TextView textItemName;
public ItemHolder(View itemView, RecyclerViewAdapter parent) {
super(itemView);
itemView.setOnClickListener(this);
this.parent = parent;
textItemName = (TextView) itemView.findViewById(R.id.item_name);
}
public void setItemName(CharSequence name){
textItemName.setText(name);
}
public CharSequence getItemName(){
return textItemName.getText();
}
#Override
public void onClick(View v) {
final OnItemClickListener listener = parent.getOnItemClickListener();
if(listener != null){
listener.onItemClick(this, getPosition());
}
}
}}

Button OnClickListener within ListView

I am having some trouble with my button listener in my listView. I have my custom adapter which is printing out my row (TextView..Button..Edittext..Button), Within this class I have set up my Listeners. What I am trying to do is when either one of the buttons is clicked they will increment or decrement the editText in the row. The trouble that I am having though is the onClickListener() and getLayoutInflater() are both coming up red. How do I fix this and is my code correct for what I am trying to do? Thanks
My custom adapter class
package com.example.rory.dbtest;
import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.CursorAdapter;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.TextView;
import com.pinchtapzoom.R;
public abstract class CustomCursorAdapter extends CursorAdapter implements View.OnClickListener {
public int counter = 0;
public CustomCursorAdapter(Context context, Cursor c) {
super(context, c);
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
// when the view will be created for first time,
// we need to tell the adapters, how each item will look
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View retView = inflater.inflate(R.layout.row, parent, false);
return retView;
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
// here we are setting our data
// that means, take the data from the cursor and put it in views
TextView textViewPersonName = (TextView) view.findViewById(R.id.item1);
textViewPersonName.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(0))));
}
public View getView(final int position, View convertView, ViewGroup parent)
{
if (convertView == null)
{
LayoutInflater inflater = getLayoutInflater();
convertView = (LinearLayout)inflater.inflate(R.layout.row, null);
}
final EditText edit1 = (EditText)convertView.findViewById(R.id.runningTotal);
Button plusButton = (Button) convertView.findViewById(R.id.plusButton);
plusButton.setOnClickListener(new onClickListener()
{
public void onClick(View v)
{
counter++;
edit1.setText(Integer.toString(counter));
}
});
//final EditText edit1 = (EditText)convertView.findViewById(R.id.runningTotal);
Button minusButton = (Button) convertView.findViewById(R.id.minusButton);
plusButton.setOnClickListener(new onClickListener()
{
public void onClick(View v)
{
counter--;
edit1.setText(Integer.toString(counter));
}
});
return convertView;
}
}
And if it is needed my XML file for each row
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView android:id="#+id/item1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="30sp"
android:paddingBottom="5dp"
android:hint="#string/hint"/>
<Button
android:id="#+id/plusButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/plusButton"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<EditText
android:id="#+id/runningTotal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="#string/hint"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/minusButton"
android:layout_toStartOf="#+id/minusButton"
android:layout_marginRight="30dp" />
<Button
android:id="#+id/minusButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/minusButton"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>

Instead of getLayoutInflater() use
LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
you can get the context from the constructor:
Context context;
public CustomCursorAdapter(Context context, Cursor c) {
super(context, c);
this.context = context;
}
And instead of onClickListener use View.onClickListener
You can remove the implements View.OnClickListener as well, you're not using it anyway.

Android Dynamic List View

I want to fix a button on top of the layout and just below the button a dynamic edit text is created. I am creating my own Adapter. On button click another activity starts and returns string which is to be shown on the list view items below the button. How can I do this ?
My XML Layout -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button1"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
<EditText
android:id="#+id/etList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" >
</EditText>
</LinearLayout>
My list view adapter -
package com.example.tasktable;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.TextView;
public class TaskAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
Button click;
TextView textView;
public TaskAdapter(Context context, String[] values) {
super(context, R.layout.list_view, values);
this.context = context;
this.values = values;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflator = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflator.inflate(R.layout.list_view, parent, false);
click = (Button) rowView.findViewById(R.id.button1);
textView = (TextView) rowView.findViewById(R.id.etList);
textView.setText(values[position]);
return rowView;
}
}
I don't want to inflate button with every edit text.

You can position layout elements with Relative Layouts https://developer.android.com/reference/android/widget/RelativeLayout.html

LayoutInflater not Updating the View Property

I am simply using LayoutInflater to get A View(Button) From a layout.xml file other then the activity_main.xml. but When I change the setText("") property of the button the button property does not updates.
I am checking if I can change the text property of the button element in the testlayout.xml But when I set the property of the Button in onCreate and when I check for that property in call that was not changed...
MainActivity.java
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LayoutInflater inflater = (LayoutInflater)this.getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout linearLayout = (LinearLayout) inflater.inflate(R.layout.testlayout, null);
Button btn = (Button)linearLayout.findViewById(R.id.testbtn);
btn.setText("Hello");
}
public void call(View v){
Button btn = (Button)findViewById(R.id.testBtn);
Toast.makeText(this, btn.getText(), Toast.LENGTH_SHORT).show();
}
Activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView
android:layout_width="wrap_content"

<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="73dp"
android:text="Button"
android:onClick="call"
/>
</RelativeLayout>
testlayout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/testBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>

You need to add this linearlayout to your activity:
LayoutInflater inflater = (LayoutInflater)this.getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout linearLayout = (LinearLayout) inflater.inflate(R.layout.testlayout, null);
Button btn = (Button)linearLayout.findViewById(R.id.button1);
btn.setText("Hello");
RelativeLayout rl=findViewById(R.id.root);
rl.addView(linearLayout);

You need to add testlayout.xml as a child to the activity view using ViewGroup.addView(View child) method. Currently you see the button from the first layout. What are you trying to do ?

You need to add the other xml to your current view :-
package com.example.testdynamicviews;
import android.app.Activity;
import android.graphics.Color;
