EditText autoscroll doesn't work after showing dialog

I'm developing an app for users to share their books. To achieve this, I'm getting different data about the book from the user. The problem is, horizontal autoscrolling of all EditTexts are working until Dialog has been shown and dismissed. Once a dialog has been dismissed on the fragment, horizontal autoscrolling of the EditText's on this layout won't work.
I added:
android:focusable="true"
android:focusableInTouchMode="true"
to parent layout of the edittext but doesn't work.
Also to make sure that autoscrolling is enabled I've added:
android:scrollHorizontally="true"
But none of above helped.
Here is XML code of the fragment layout.

UI Design and Dialog
In the image above, there are EditTexts Name Of Book and Name of Author. Before showing a dialog, both of them work like a charm. When writing something, the cursor automatically scrolls to the end. Once Dialog has been shown and dismissed, none of them works properly, and the cursor stays at the end of the EditText but still the characters are being written continues in the hidden part.
In this UI it cannot be seen because of the issue, but I've written.

Weird buggy layout UI image
Please, help me to solve this problem. Thanks in advance.

As a solution, I don't know the underlying reason, but the problem solved once I removed Butterknife library from my project.

Animation Problems in Android

I've got few problems in using animation in android studios:
I'm trying to translate certain images at an angle. Like in the image below I want to move that attachment pin like icons to all the ends of the corner. How can I do this?
I was trying to scale up the image of the gear image in the center every time its tapped and scale down when tapped again. However, the image starts losing its quality. How can I prevent the quality from getting deteriorated?
Here's the code:
MainActivity.java

public class MainActivity extends AppCompatActivity {
PulseView pulseView;
Button btnStart, btnStop;
ImageView gear;
ImageView icon1,icon2,icon3,icon4,icon5,icon6;
int chkClick = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pulseView = (PulseView)findViewById(R.id.pv);
btnStart = (Button)findViewById(R.id.btnStart);
btnStop = (Button)findViewById(R.id.btnStop);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pulseView.startPulse();
}
});
btnStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pulseView.finishPulse();
}
});
gear = (ImageView)findViewById(R.id.gear);
gear.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
gear.animate().scaleX(1.5f).scaleY(1.5f).setDuration(500);
animateDiagonalPan();
icon1 = findViewById(R.id.icon1);
icon1.animate().translationXBy(120).translationYBy(120).setDuration(500);
if(chkClick==0)
{
pulseView.animate().alpha(0).setDuration(500);
gear.animate().scaleX(1.5f).scaleY(1.5f).setDuration(500);
pulseView.finishPulse();
chkClick = 1;
}else{
pulseView.animate().alpha(1f).setDuration(500);
gear.animate().scaleX(1f).scaleY(1f).setDuration(500);
pulseView.startPulse();
chkClick = 0;
}
}
});

Dynamically Remove EditText Field in LinearLayout

My problem is that once my editText fields are created, I don't know how to remove them one by one with the other button in my app. I don't really understand the android:id element as it relates to setID() in my java code. I guess my main question is, how do I figure out how to target dynamically created editText views with their id's if I don't know their id's. Here is my code, any help is really appreciated:

There is no relationship between android:id and your setID.
Check this answer to unsderstand more about that.
Anyway, one approach to achieve to remove a generated line could be based on the children index of your LinearLayout like this:
private LinearLayout mEditTextContainer;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
mEditTextContainer = (LinearLayout)findViewById(R.id.linearLayoutDecisions);
...
}
public void addLine() {
// add edittext
EditText et = new EditText(this);
LinearLayout.LayoutParams p = new
LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
et.setLayoutParams(p);
et.setText("Enter Answer #" + (mEditTextContainer.getChildCount()+1));
mEditTextContainer.addView(et);
Toast.makeText(MainActivity.this, "1", Toast.LENGTH_LONG).show();
}
public void removeLine() {
mEditTextContainer.removeViewAt(mEditTextContainer.getChildCount()-1);
}

CardView not displaying content due any errors

I created a Recyclerview in my main_activity and I wanted to use this cardview in a partial activity... I put extras variables and data to the new activity but any thing not showing in new activity...
this is my partial xml code (hotel_page.xml) :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:orientation="vertical">
<android.support.v7.widget.CardView
android:id="#+id/card_view1"
android:layout_width="match_parent"
android:layout_height="288dp"
android:layout_margin="#dimen/card_margin"
android:elevation="3dp"
card_view:cardCornerRadius="0dp"
android:gravity="top">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/card"
android:focusable="true"
android:contextClickable="true"
android:gravity="top"
android:layout_alignParentBottom="true">
</RelativeLayout>
</android.support.v7.widget.CardView>
<TextView
android:id="#+id/title1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="10dp"
android:paddingRight="25dp"
android:paddingTop="10dp"
android:textColor="#color/cardview_dark_background"
android:textSize="15dp"
android:layout_above="#+id/count1"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<ImageView
android:id="#+id/thumbnail1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/selectableItemBackgroundBorderless"
android:clickable="true"

<TextView

android:textSize="12dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</LinearLayout>
This is My HotelPageList.java :
package ir.homa;
public class HotelPageList {
private String name;
private int numOfRooms;
private int thumbnail;
public HotelPageList() {
}
public HotelPageList(String name, int numOfRooms, int thumbnail) {
this.name = name;
this.numOfRooms = numOfRooms;
this.thumbnail = thumbnail;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNumOfRooms() {
return numOfRooms;
}
public void setNumOfRooms(int numOfRooms) {
this.numOfRooms = numOfRooms;
}
public int getThumbnail() {
return thumbnail;
}
public void setThumbnail(int thumbnail) {
this.thumbnail = thumbnail;
}
}
This is HotelPageAdapter.java :
package ir.homa;
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.ImageView;
import android.widget.TextView;
import com.bumptech.glide.Glide;
import java.util.List;
/**
* Created by SMQ on 7/20/2016.
*/
public class HotelPageAdapter extends RecyclerView.Adapter<HotelPageAdapter.MyViewHolder> {
private Context mContext;
private List<HotelPageList> hotelPage;
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title1, count1;
public ImageView thumbnail1, overflow1;
public MyViewHolder(View view) {
super(view);
title1 = (TextView) view.findViewById(R.id.title1);
count1 = (TextView) view.findViewById(R.id.count1);
thumbnail1 = (ImageView) view.findViewById(R.id.thumbnail1);
overflow1 = (ImageView) view.findViewById(R.id.overflow);
}
}
public HotelPageAdapter(Context mContext, List<HotelPageList> hotelPage) {
this.mContext = mContext;
this.hotelPage = hotelPage;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.hotel_page, parent, false);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
final HotelPageList hotel = hotelPage.get(position);
holder.title1.setText(hotel.getName());
holder.count1.setText(hotel.getNumOfRooms() + " اتاق");
// loading hotel cover using Glide library
Glide.with(mContext).load(hotel.getThumbnail()).into(holder.thumbnail1);
}
#Override
public int getItemCount() {return hotelPage.size();}
}
and this is result:
Where is problem ?
