Fragment editText data getting cleared when i am moving to another activity and coming back

I have an FragmentActivity which contain WebView, Edittext1, Edittext2, Checkboxes and button. When I click the button in fragment it will move to Results_activity. And if I click button from Results_activity it move back to FragmentActivity.
But my edittext values getting cleared while moving back.

this is my question yearwise activity(from this I launched the fragment activity)

protected void onCreate (Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.question_yearwise);
Button btn2018ii = (Button)findViewById(R.id.btn2018ii);

public void onClick(View v) {

MyServerData2018ii.getInstance().setTestState("inProgress");
startActivity(Quiz2018ii);
}
});
}
}

Replace the method like this,
mainView.findViewById(R.id.check_results).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});

UI glitch in Listview android

I'm implementing a ListView and on quick scrolling in large lists this glitch occurs. I am using ViewHolder Pattern
[![UI Glitch in ListView][1]][1]

getView :
public View getView(int position, View convertView, ViewGroup parent) {

}
This does not occur all the time, and it doesn't occur for small lists. I have no other common problems described in other posts here (as long as this glitch doesn't occur, all views work correctly, and are in proper order).

How can I put numbers In several TextViews?

Hey I have gridview buttons like keyboard with green light if I click on one of them turns to red anyways and I have 4 TextViews so I want when I press a number text it on textview1 then second number goes to txt2 the third to txt3 the fourth to txt4 but the txt4 must be changeable if I pressed on another number automatically changes and it is important that I can't use same number for example in txt1 I pressed number 1 the button goes red so I can't use it in txt2,3,4 Until I delete it from txt1 look at my picture and if someone want the code i'm happy to put it
(and how automatically jumps to the next textview after one number)
MainActivity.java this helps me with edit text I want it for TextView

button_selector.xml Place this in your drawable folder.
<?xml version="1.0" encoding="utf-8"?>

</selector>
Logic (as OP asked for it)
The values array stores the numbers that are supposed to be displayed in TextViews.
When a button is pressed the values array is updated in the setText() method.
When clear is pressed this is what happens -
if (size == 0) {
return; // if size is 0 do nothing.
}
String numberToCleared = values[size - 1];
//You've to clear the button color. So, get the last value in array
//and send it to clearButton() function.
clearButton(Integer.parseInt(numberToCleared));
//remove the number from values array and decrement size
size--;
values[size] = " ";
bindText();
break;

Hope this code helps you !!!
if its not working please let me know i will try to help more.
