Horizontally Scrolling Text Performance Issues

My app contains a few textViews which are supposed to be scrolling horizontally. This works when my layout is first loaded but after clicking on a button to load another layout and then re-click on that button to load back the first layout those textViews start scrolling after a "big" delay(like 20 secs+). I'm trying to figure out the source of this problem with the Layout Inspector, Hierarchy Viewer etc. but no luck.
UPDATE: I noticed something strange today.When i go from the 1st layout to the 2nd one and vice versa, although the TextViews stop scrolling, if i close and re-open the phone's screen, the scrolling works like a charm. This seems totally strange to me, do you know what's causing this and why?

I'd suggest using a RecyclerView with a custom Adapter, RecyclerView can be used vertically or horizontally.

Only shows one tetview rating

I am developing an app to help people know when it is time for a phone upgrade. I ran into a little problem along the way, mainly when trying to test the functionality of the code. I rated all 6 categories and pressed the continue button. Only the rating for the "Game" shows up. I don't know what is going on since I have all six textviews included.

Your code is fine, try rebuild/clean the project.
If you're using Android Studio, go to Build -> Clean Project and then Build -> Rebuild Project.

Hide and show when check box is checked

In my Activity A , I have checkbox, spinner and editText. If checkbox is checked, it will show editText and hide spinner and textView .Otherwise, it will show them.
public void addListenerOnChk() // for checkbox
{
checkBox2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(((CheckBox)v).isChecked())
{
typeProject.setVisibility(View.VISIBLE);
project.setVisibility(View.GONE);
ProjectName.setVisibility(View.GONE);
}
else
{
typeProject.setVisibility(View.GONE);
project.setVisibility(View.VISIBLE);
ProjectName.setVisibility(View.VISIBLE);
}
}
});
So this is my layout
Before checkbox is checked
After
If the checkbox did not checked, how can I move the progress bar below the checkbox(Currently it has a space for editText)?
If checkbox checked, how to move up the checkbox and hide the spinner and text ? Thanks.
Here my layout...sorry, it a bit long (but the things I want to change is id/ProjectName, id/checkbox2 and id/editText). id/checkbox2 and id/editText is in the last two paragraph.

Your problem is because you are using absolute_layout with layout_x and layout_y, so all views will be at your predefined positions of x and y, no matter what elements will you remove or what elements will you leave.
So, you have to change the layout parameters for the elements not just set it's visibility to VISIBLE or GONE, so the complete solution will be:
checkBox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
typeProject.setVisibility(View.VISIBLE);
project.setVisibility(View.GONE);
ProjectName.setVisibility(View.GONE);
// now settings the new parameters
AbsoluteLayout.LayoutParams params = ((AbsoluteLayout.LayoutParams) typeProject.getLayoutParams());
params.x = 100; // the new value
params.y = 100; // the new value
typeProject.setLayoutParams(params);
}
else{
typeProject.setVisibility(View.GONE);
project.setVisibility(View.VISIBLE);
ProjectName.setVisibility(View.VISIBLE);
// use the same way here with 'project' and 'ProjectName'
}
});

Try with OnCheckedChangeListener:
checkBox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
typeProject.setVisibility(View.VISIBLE);
project.setVisibility(View.GONE);
ProjectName.setVisibility(View.GONE);
}
else{
typeProject.setVisibility(View.GONE);
project.setVisibility(View.VISIBLE);
ProjectName.setVisibility(View.VISIBLE);
}
});

You should use OnCheckedChangeListener, rather than OnClickListener
Do this
checkBox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
if(isChecked)
{
typeProject.setVisibility(View.VISIBLE);
project.setVisibility(View.GONE);
ProjectName.setVisibility(View.GONE);
}
else
{
typeProject.setVisibility(View.GONE);
project.setVisibility(View.VISIBLE);
ProjectName.setVisibility(View.VISIBLE);
}
}
});

storing value of EditText to a string variable is not working

My question is different from other questions previously asked on this site on the same topic. The answer as to how we can store text from EditText field to a string was given as
EditText input = (EditText) findViewById(R.id.inputId);
String str = input.getText().toString();
my question is a bit different.
my java main activity is:
package com.example.fahadsaleem.xyz;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import org.w3c.dom.Text;
public class MainActivity extends AppCompatActivity {
public String str;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView calc_monday = (TextView) findViewById(R.id.monday_calc);
calc_monday.setOnClickListener(
new Button.OnClickListener(){
public void onClick(View v){
CustomDialogClass cdd = new CustomDialogClass(MainActivity.this);
cdd.show();
TextView text1 = (TextView) cdd.findViewById(R.id.Subject_ID);
text1.setText(str);
TextView text2 = (TextView) cdd.findViewById(R.id.Room_ID);
text2.setText("6 (SEECS)");
TextView text3 = (TextView) cdd.findViewById(R.id.Time_ID);
text3.setText("09:00am 09:50am");
}
}
);
calc_monday.setOnLongClickListener(
new Button.OnLongClickListener() {
public boolean onLongClick(View v) {
kj monday_calc = new kj(MainActivity.this);
monday_calc.show();
return true;
}
}
);
}
}
The kj class has the following code:
package com.example.fahadsaleem.xyz;
import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
/**
* Created by Fahad Saleem on 12/22/2015.
*/
public class kj extends Dialog implements android.view.View.OnClickListener {
public Activity c;
public Dialog d;
public Button back;
public kj(Activity a) {
super(a);
// TODO Auto-generated constructor stub
this.c = a;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.setting_dialog);
back = (Button) findViewById(R.id.set_btnn);
back.setOnClickListener(this);
}
#Override
public void onClick(View v){
switch (v.getId()){
case R.id.set_btnn:
MainActivity police = new MainActivity();
EditText set_monday_calc = (EditText) findViewById(R.id.set_Subject_ID);
// Store EditText in Variable
police.str = set_monday_calc.getText().toString();
dismiss();
break;
default:
break;
}
dismiss();
}
}
Basically the app's interface has a time table of subjects. When you click on a subject name, a dialog box appears showing 3 things: Subject name, room number and time period.
Now what I want is I should be able to change the 3 things by making a long click on the subject name. I am trying to use this button in class kj to achieve that:
case R.id.set_btnn:
MainActivity police = new MainActivity();
EditText set_monday_calc = (EditText) findViewById(R.id.set_Subject_ID);
// Store EditText in Variable
police.str = set_monday_calc.getText().toString();
dismiss();
this variable str is declared in MainActivity java file. When the user enters the text on the subject name and clicks on this button, the text should be stored in the str variable.
But this is not happening. When I start writing any text on the EditText field on my interface which looks like this:
The following error is seen in the log:
then when I click Go Back button which should set the text I wrote to variable str, the following error is seen in the log:
Later on when I single click on the subject, what I wrote before I clicked on the button is not being showed, rather a blank space is being shown as was declared by this line in mainactivity java file:
public String str;
Like this:
What is the problem? Here are the rest of the files:
CustomDialogClass:
package com.example.fahadsaleem.xyz;
import android.app.Activity;

I did not post the whole of java main activity, I only posted that which is relevant.

I haven't noticed you're using any database. I see that in your app you need to share data between classes, so MUST HAVE is to use SharedPreferences standard database:
Read please this:
How to use SharedPreferences in Android to store, fetch and edit values
You tried to get a string value which was temporary and available only for specific class. That's your problem. Solution above.
Hope it help

In onClick you are creating a new instance with which you don't really seem to be doing anything.
If you were to have in you kj class something like:
public MainActivity c;
...
public kj(MainActivity a) {
and then in onClick(View v) under "case R.id.set_btnn":
c.str = set_monday_calc.getText().toString();
you would manage to update str.

Updating button in android

I am creating an address Book app but I have a problem. When I am trying to set text to the button it doesn't update on the screen.
Here is a part of my main layout:
public void call(View v){
setContentView(R.layout.call);
Numbers num = new Numbers(cont);
final Names names = new Names(cont);
button = (Button) findViewById(R.id.name1);
if(num.getNumber("1").isEmpty()) {
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setContentView(R.layout.activity_aseta_numero);
Button button1 = (Button) findViewById(R.id.readyButton);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
EditText text = (EditText) findViewById(R.id.Number);
Numbers j = new Numbers(cont);
j.setNumber(text.getText().toString(), "1");
EditText tex = (EditText) findViewById(R.id.NameField);
names.adName(tex.getText().toString(), "1");
button.setText(names.getNimi("1") + "moi");
setContentView(R.layout.call);
System.out.println(button.getText());
}
});
}
});
}else {
}
Here is my name class:
public class Names extends Activity{
SharedPreferences pres;
Button Nappi;
Context context;
public Names(Context mcontext){
context = mcontext;
pres = context.getSharedPreferences("1",0);
}
public void adName(String name, String place){
SharedPreferences.Editor editor = pres.edit();
editor.putString(name,place);
editor.commit();
System.out.println(pres.getString("1", ""));
}
public String getName(String place){
return pres.getString(place,"");
}
}
