Create multiplication table layout

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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity"
android:weightSum="1">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView

android:textSize="20sp" />
<EditText

<Button

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

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:

How do I create popup input field for Android?
I need Xml and Java Code.

try to use this custom popup dialog code
main.xml
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"

<EditText

</LinearLayout>
main.java
package cm.kikani.kalpesh;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
final Context context = this;
private Button button;
private EditText result;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// components from main.xml
button = (Button) findViewById(R.id.buttonPrompt);

});
// create alert dialog

}
}

You can create a custom dialog class for your case.
your_custom_dialog.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="120dp"
android:background="#android:color/black"
android:orientation="vertical" >
<TextView
android:id="#+id/txt_exit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="10dp"
android:text="Do you realy want to exit ?"
android:textColor="#android:color/white"
android:textSize="16sp"
android:textStyle="bold"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#android:color/blue"
android:orientation="horizontal" >
<Button
android:id="#+id/btn_yes"
android:layout_width="100dp"
android:layout_height="30dp"
android:background="#android:color/white"
android:clickable="true"
android:text="Yes"
android:textColor="#android:color/white"
android:textStyle="bold" />
<Button
android:id="#+id/btn_no"
android:layout_width="100dp"
android:layout_height="30dp"
android:layout_marginLeft="5dp"
android:background="#android:color/white"
android:clickable="true"
android:text="No"
android:textColor="#android:color/blue"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
and you CustomDialog class must extend Dialog
public class CustomDialogClass extends Dialog {
public Activity activity;
public Dialog dialog;
public Button yes, no;
public CustomDialogClass(Activity a) {
super(a);
// TODO Auto-generated constructor stub
this.activity = a;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.custom_dialog);
yes = (Button) findViewById(R.id.btn_yes);
no = (Button) findViewById(R.id.btn_no);
yes.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
activity.finish();
}
});
no.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
dismiss();
}
});
}
}
and you can call it like this
CustomDialogClass customDialog =new CustomDialogClass(activity);
customDialog .show();

i need to make a button that opens a custom dialogbox

I'm creating an android app for my school project.

public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
And when this appears and I type in and click on next. This dialog box dismisses and another msg box I'll create later shows a msg.
how to do it ?

Here is a fully working code for you:
Context context = getAplicationContext();
final Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.your_dialog_layout);
Button button2 = (Button) dialog.findViewById(R.id.Suivantbtn);
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog2 = new Dialog(context);
dialog2.setContentView(R.layout.your_second_dialog_layout);
Button button3 = (Button) dialog2.findViewById(R.id.Suivantbtn2);
button3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog2.dismiss();
}
});
dialog.dismiss();
dialog2.show();
}
});
dialog.show();
}
});
Hope my answer helped!

Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener(){
#Override
//On click function
public void onClick(View view) {
//do something - for example open the dialog box you want
final Dialog dialog = new Dialog(getActivity());
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_alert_dialogue);
dialog.show();
}
});

You should add onClickListener to your buttons. For example (this code is for your Activity class):
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener(){
#Override
//On click function
public void onClick(View view) {
//do something - for example open the dialog box you want
}
});
