Question

Im working on an app designed for android 3.0 onwards, and I want to use one button to first setText in a text view and then change screen from screen1 to screen2…

Here is my code so far (causes a crash):

    Button mainNext = (Button) findViewById(R.id.Recipe1);
    mainNext.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {

            final TextView mTextView = (TextView) findViewById(R.id.textView3);
            mTextView.setText("Some Text");

            Intent i = new Intent();
            i.setClassName("com.bluStudios.Recipes4U.ics", "com.bluStudios.Recipes4U.ics.recipedisplayscreen");
            startActivity(i);
        }
    });

Any ideas???
Thanks in advance 😛

EDIT:

Code for 1st screen:

public class Recipe_Button_List extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.recipe_button_list);


    Button mainNext = (Button) findViewById(R.id.Recipe1);
    mainNext.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            final TextView mTextView = (TextView) findViewById(R.id.textView3);
            mTextView.setText("Some Text");
Intent i= new Intent(Recipe_Button_List.this, recipedisplayscreen.class); 
            startActivity(i);
        }
    });
}

}

Code for 2nd screen:

public class recipedisplayscreen extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.recipedisplayscreen);
    ActionBar actionBar = getActionBar();
    setTitle(R.string.title);
    actionBar.setDisplayHomeAsUpEnabled(true);}

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                // App icon in action bar clicked; go home
                Intent intent = new Intent(this, MainScreen.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(intent);
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.recipe_menu1, menu);
        return true;

}

}

Answer 1

use this :

    Button mainNext = (Button) findViewById(R.id.Recipe1);
        mainNext.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                final TextView mTextView = (TextView) findViewById(R.id.textView3);
                mTextView.setText("Some Text");
    Intent i= new Intent(YOUR_CURRENT_ACTIVTY_NAME.this, recipedisplayscreen.class); 
///or  you can use Intent i= new Intent(getBaseContext(),recipedisplayscreen.class); 
                startActivity(i);
            }
        });

and must recipedisplayscreen activity in AndroidManifest.xml
