Question

I’m writing a recipe book, and I’ve encountered a problem, my screen2 recieves null.null when I send information from screen1 …

This is my code for recipe_button_list:

public class Recipe_Button_List extends Activity {

    TextView inputMethod;

    TextView inputIngredients;

    @Override
    public void onCreate( Bundle savedInstanceState ) {

        super.onCreate( savedInstanceState );
        setContentView( R.layout.recipe_button_list );

        inputMethod = (TextView) findViewById( R.id.textView2 );
        inputIngredients = (TextView) findViewById( R.id.textView1 );
        //remember when adding more intents to make sure that they are classed as TextView not EditText

        ActionBar actionBar = getActionBar();
        actionBar.setDisplayHomeAsUpEnabled( true );

        Button mainNext = (Button) findViewById( R.id.Recipe1 );
        mainNext.setOnClickListener( new OnClickListener() {

            public void onClick( View v ) {

                final TextView mTextView = (TextView) findViewById( R.id.textView1 );
                mTextView.setText( R.string.Test2 );
                final TextView mTextView2 = (TextView) findViewById( R.id.textView2 );
                mTextView2.setText( R.string.Test );
                Intent i = new Intent( getBaseContext(), recipedisplayscreen.class );
                //Sending data to the next screen
                i.putExtra( "textView1", inputIngredients.getText().toString() );
                i.putExtra( "textView2", inputMethod.getText().toString() );

                Log.e( "n", inputMethod.getText() + "." + inputIngredients.getText() );
                startActivity( i );
            }
        } );

        Button mainNext2 = (Button) findViewById( R.id.Recipe2 );
        mainNext2.setOnClickListener( new OnClickListener() {

            public void onClick( View v ) {

                final TextView mTextView = (TextView) findViewById( R.id.textView1 );
                mTextView.setText( R.string.Test );
                Intent i = new Intent( getBaseContext(), recipedisplayscreen.class );
                //Sending data to the next screen
                i.putExtra( "textView1", inputIngredients.getText().toString() );
                i.putExtra( "textView2", inputMethod.getText().toString() );

                Log.e( "n", inputMethod.getText() + "." + inputIngredients.getText() );
                startActivity( i );
            }
        } );
    }

    @Override
    public boolean onCreateOptionsMenu( Menu menu ) {

        MenuInflater inflater = getMenuInflater();
        inflater.inflate( R.menu.recipe_menu1, menu );
        return true;

    }
}

This is my recipe_display_screen:

public class recipedisplayscreen extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.recipedisplayscreen);

        TextView MethodDisplay = (TextView) findViewById(R.id.textView3);
        TextView IngredientsDisplay = (TextView) findViewById(R.id.textView5);

        Intent i = getIntent();
        String Ingredients = i.getStringExtra("TextView1");
        String Method = i.getStringExtra("TextView2");
        Log.e("recipedisplayscreen", Ingredients + "." + Method);

        MethodDisplay.setText(Method);
        IngredientsDisplay.setText(Ingredients);


        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;

    }

}

Any ideas, solutions ??? Thanks in advance 🙂

Answer 1

    Intent i = getIntent();
    String Ingredients = i.getStringExtra("textview1"); <--- see diff TextView1
    String Method = i.getStringExtra("textview2"); <--- see diff TextView2
    Log.e("recipedisplayscreen", Ingredients + "." + Method);

when you are passing value you are useig T and V small

and t and v are in capital where you are getting values
