Create multiplication table layout - android

I am trying to generate Multiplication Table of any number that is input by user. I have developed the interface for the application but cannot understand where to start with the logical part(coding). What i want is when a user inputs a number into the EditText then in the TextView (id: printArea) should show the table of the input number in the format as given in image 2. [Just to show you example i used TextView in the printArea part and i do not know what to use instead]
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

and the MainActivity.java is:
package com.example.tara.multiplicationtable;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;

import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
EditText num;
Button credits;
Button calculate;
Button clear;
Button exit;
TextView printArea;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
num = new EditText(this);
clear = new Button(this);
calculate = new Button(this);
credits = new Button(this);
calculate = new Button(this);
printArea = new TextView(this);
num = (EditText) findViewById(R.id.num);
credits = (Button) findViewById(R.id.credits);
clear = (Button) findViewById(R.id.clear);
exit = (Button) findViewById(R.id.exit);
printArea = (TextView) findViewById(R.id.printArea);
calculate = (Button) findViewById(R.id.calculate);
calculate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//change the integer value into string
int num1 = Integer.parseInt(num.getText().toString());
// Perform action on click
for (int i = 1; i <= 10; i++) {
printArea.setText(num1 + "X" + i + "=" + i * num1);
}
}
});
clear.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
num.setText("");
}
});
credits.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this, Credits.class);
startActivity(i);
}
});
exit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
System.exit(0);
}
});
}
}
when application is launched it should show like thisThe initial state of application
and i want to make the application show the table like this if user input is 2 The Final Result

Make a Listview and then in its adapter add your table data.
Make adapter's layout like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="2" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="*" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="2" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="=" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="4" />

Here are the codes that i used to build the Multiplication Table that i imagined to build. The code for activity_main.xml file will be:
<?xml version="1.0" encoding="utf-8"?>

What is the meaning of SETAFFINITY ret = -1 in Android Studio? Here is the log of my Activity

In the below code, I've set the new Intent in the autocomplete_next TextView, but in my Mobile, when I run the app, and When I try to move to the next activity, It does not go the next Activity, Instead of that, it comes back again to the same previous Activity. In the Android Studio LOGCAT, I've seen the RenderScript: SETAFFINITY ret = -1 . I got no trace about this error on Google? Please Help me to fix my issue. Thank You in Advance...

Buttons wont work when used with created xml (Android Studio)

I've made a working simple calculator with some bugs here and there, I decided to make all the buttons round by adding the appropriate drawable xml files to make them round sadly after doing so the buttons now won't work.
Here is the Main.java

I've been trying to find the problem for a while now any help is greatly appreciated thank you.
PS. How do I lessen the number of xml files but still have a variety of round buttons with different colors?
My calculator was not showing any numbers after pushing the corresponding buttons, I realized the I changed the background color to black while my textView font color was also black, for anyone who was trying to comprehend my question and trying their best to help me I am deeply sorry for wasting your time and thank you.

As Kuti suggested, its better to keep only one OnClickListener, so keep his advice in mind.
A Boolean is an object, is not true or false, so the sentence if(addButton) when addButton is a Boolean is always false. Try using addButton.booleanValue() or use a boolean instead of a Boolean

why custom dialog buttons dont work?

I have a custom dialog in my app but when I click on the buttons of dialog they don't work!
I want to show dialog in one of the items of navigation drawer
and that's code:
dialog = new Dialog(MaterialCardsActivity.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(true);
dialog.setContentView(R.layout.dialog_mail);
dialog.show();
How can I resolve it?
