Android Studio - Start an Activity with a parameter

I am new with Android Studio. I am working on following code but it is not working, kindly help me out.

I am trying to send an int value but emulator stopped working every time.

From class page1 to page2. On page1:

        b1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(page1.this, page2.class);
            Bundle b = new Bundle();
            b.putInt("key", 1); //Your id
            intent.putExtras(b); //Put your id to your next Intent
            startActivity(intent);
        }
    });

On page2: I am writing this code in onCreate function.

    Bundle coming = getIntent().getExtras();
    int value = coming.getInt("key");
    paper.setText(value);

There are few ways to do it, It is depend on your requirement. I'll show how it can be done,

  1. If you want to pass single parameter it is better to pass it with the intent like follow.

b1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(getApplicationContext(), page2.class); intent.putExtra("key", 1); //Your id startActivity(intent); } });

and you can receive data back in page2 Activity as 

int id = getIntent().getIntExtra("key",1);

  1. Can use bundle for pass bundle of data

    b1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(getApplicationContext(), page2.class); //Create the bundle Bundle bundle = new Bundle(); //Add your data from getFactualResults method to bundle bundle.putString("key", 1); //Add the bundle to the intent intent.putExtras(bundle); startActivity(intent); } });

receive data from page2 Activity

Bundle bundle = null; bundle = this.getIntent().getExtras(); String keyString = bundle.getString("Name");//this is for String

  1. Add data to the sharedPreferences and retrieve it from page2 Activity

SharedPreferences sp =getSharedPreferences(logFile, 0); SharedPreferences.Editor editor = sp.edit(); editor.putString("id", 1); editor.commit();

And can retrive it from next page

Before setText convert value int to String 

paper.setText(String.valueOf(value));

You need to set a text value to your TextView

Bundle coming = getIntent().getExtras();
int value = coming.getInt("key");
// Add an empty string to value
paper.setText(value + "");

You have to cast int to String as you are trying to set it to TextView

So change:

paper.setText(value);

to:

paper.setText(String.valueOf(value));
