Trying to send a view's id with an intent. Getting "false"

This class has information that I want to send with an intent to another activity. When the image button "superman" is pressed the onClick() handler sends an intent to SuperheroActivity. But when I try and retrieve that information in the other activity I get "false".

public class MenuActivity extends Activity implements
    OnClickListener {
private ImageButton superman;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.menu);

    superman = (ImageButton) findViewById(R.id.superman);
    superman.setOnClickListener(this);
}

@Override
public void onClick(View v) {
    Intent intent = new Intent(MenuActivity.this, SuperheroActivity.class);
    intent.putExtra("id", v.getId());
    startActivity(intent);开发者_如何转开发
}

}

This is the piece of code that tries to retrieve the information from the intent. Note: This is SuperheroActivity.

Intent intent = getIntent();
id = intent.getIntExtra("id", 0);
// This is just a dirty way for me to see the value of the id I am getting.
TextView text = (TextView) findViewById(R.id.superheroText); 
text.setText(id);

The bug is in this line of code.

text.setText(id);

means the resource id (i.e String resource id). try replacing and using this.

text.setText(String.valueOf(id));

use id = intent..getExtras().getInt("id") to get data from the intent...

SuperheroActivity

Bundle extras = getIntent().getExtras();
id = extras.getInt("id");
TextView text = (TextView) findViewById(R.id.superheroText); 
text.setText(id+"");

Get the bundle using getExtras()

Intent intent = getIntent();
id = intent.getExtras().getInt("id");

REMEMBER You cant setText(int)! the int must be a String

So change

TextView text = (TextView) findViewById(R.id.superheroText); 
text.setText(id);

to

TextView text = (TextView) findViewById(R.id.superheroText); 
text.setText(String.valueOf(id)); //change id to a string
