hamid I don't find any difficulty upon your problem. These can be done by just basic of Android skills. However I have simple prototype for your password generator.

Just write this XML code for simple layout of your app. <?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="match_parent" android:gravity="center" android:orientation="vertical"> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:layout_marginEnd="10dp" android:id="@+id/txt"/> <Button android:text="click" android:layout_width="100dp" android:layout_height="wrap_content" android:layout_marginTop="72dp" android:id="@+id/btn"/> </LinearLayout>

And just paste this following code for MainActivity.java. package com.mycompany.myapp; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button btn=(Button)findViewById(R.id.btn); final TextView txt=(TextView)findViewById(R.id.yxt); btn.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View p1) { txt.setText(generatePwd(6).toString()); } }); } static char[] generatePwd(int len) { System.out.println("Your Password:"); String charsCaps = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; String chars = "abcdefghijklmnopqrstuvwxyz"; String nums = "0123456789"; String symbols = "!@#$%^&*_=+-/€.?<>)"; String math = "⅙½¾⁶⁷⁸⁹⅘¾⅜⅗⅔⅖⅕⅒⅑"; String nam = "★†‡«»‹›¡¿‽№€¢£¥₱—–±♣♠♪♥♦ΩΠμ§

String passSymbols = nam + math + charsCaps + chars + nums + symbols; Random rnd = new Random(); char[] password = new char[len]; int index = 0; for (int i = 0; i < len; i++) { password[i] = passSymbols.charAt(rnd.nextInt(passSymbols.length())); } return password; } }

You don't need onClick attribute in XML it's a different way of handling Click events. We will be using Click listeners. that we already have in our code.

I don't know what is your Question pointing but can you just describe your problem more clearly that people can answer you more accurately. Or did you mean jumping through different activities with a Button clicked.

hamid you are trying to run Java console program through Android sdk or Android studio. You don't need Scanner to get user input instead we will use EditText So copy this XML code between the TextView and Button. <EditText android:layout_width="150dp" android:layout_height="wrap_content" android:layout_marginTop="100dp" android:id="@+id/edt"/>

You also don't need a hole class program you can turn it into a method that returns value b instead of printing. So copy this code on MainActivity.java public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button btn=findViewById(R.id.btn); final EditText edt=findViewById(R.id.edt); final TextView txt=findViewById(R.id.txt); btn.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View p1) { try{ //Getting the user input int fruit=Integer.valueOf(edt.getText().toString()); txt.setText(Integer.toString(program(fruit))); }catch(Exception e){ } } }); } public int program(int fruit){ int a=fruit/2; int b=a/3; return b; } }
