Passing data or parameter to another Activity Android - 2

Passing data or parameter to another Activity Android - using Bundle
This following step helps to share the content using bundle.
 1. Create a two Activity [MainActivity & ChildActivity]

Activity : 1 -  MainActivity
 public class MainActivity extends Activity {
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
     }
}

 
 Activity : 2 - ChildActivity
 public class ChildActivity extends Activity {
     /**
      * @see android.app.Activity#onCreate(Bundle)
      */
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         // TODO Put your code here
     }
 }

 

2.  Define Your Shared collection
    Bundle bundle = new Bundle();
    bundle.putString("sample", "this is the test commands");
    bundle.putString("sample1", "this is the test commands1");



3. Call the child Activity from mainactivity with the bundle
    startActivity(new Intent(this, ChildActivity.class).putExtras(bundle));
 
4. Get the Value from MainActivity in ChildActivity
     this.getIntent().getExtras().getString("sample")

5. Toast the Message
    Toast.makeText(this, this.getIntent().getExtras().getString("sample"),
            Toast.LENGTH_LONG).show();
    Toast.makeText(this, this.getIntent().getExtras().getString("sample1"),
        Toast.LENGTH_LONG).show();
 

 
 Full Source :MainActivity.java
 
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;

public class MainActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Bundle bundle = new Bundle();
        bundle.putString("sample", "this is the test commands");
        bundle.putString("sample1", "this is the test commands1");
        startActivity(new Intent(this, ChildActivity.class).putExtras(bundle));
    }
}

-------ChildActivity.java----------
import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.widget.Toast;

public class ChildActivity extends Activity {
    /**
     * @see android.app.Activity#onCreate(Bundle)
     */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Toast.makeText(this, this.getIntent().getExtras().getString("sample"),
                Toast.LENGTH_LONG).show();
        Toast.makeText(this, this.getIntent().getExtras().getString("sample1"),
                Toast.LENGTH_LONG).show();
    }
}
