Question

This is what I have:

    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.ArrayAdapter;
    import android.widget.EditText;
    import android.widget.Spinner;

    public class FireScreen extends Activity implements OnClickListener {



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


    EditText FIinvolvedtext = (EditText) findViewById(R.id.FIinvolvedtext);
     String fireinvolvedsave = FIinvolvedtext.getText().toString();

        View FIUnitsStart = findViewById(R.id.FIUnitsStart);
        FIUnitsStart.setOnClickListener(this);
        View FIMainResume = findViewById(R.id.FIMainResume);
        FIMainResume.setOnClickListener(this);

        Spinner fire_type_spin = (Spinner) findViewById(R.id.FItypespin);
        ArrayAdapter<CharSequence> 
        adapter = ArrayAdapter.createFromResource(this, R.array.typespin_array, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        fire_type_spin.setAdapter(adapter);

        Spinner fire_type_array = (Spinner) findViewById(R.id.FIareaspin);
        ArrayAdapter<CharSequence> 
        adapter1 = ArrayAdapter.createFromResource(this, R.array.areaspin_array, android.R.layout.simple_spinner_item);
        adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        fire_type_array.setAdapter(adapter1);

        Spinner action_type_spin = (Spinner) findViewById(R.id.FIactionspin);
        ArrayAdapter<CharSequence> 
        adapter11 = ArrayAdapter.createFromResource(this, R.array.actionspin_array, android.R.layout.simple_spinner_item);
        adapter11.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        action_type_spin.setAdapter(adapter11);}


        public void onClick(View v) {

            switch(v.getId()){
            case R.id.FIUnitsStart:
                Intent UnitScreen = new Intent(this, UnitScreen.class);
                UnitScreen.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
                startActivity(UnitScreen);
            break;

            case R.id.FIMainResume:
                Intent Main = new Intent(this, Main.class);
                Main.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
                startActivity(Main);
            break;

            Intent pass = new Intent(getApplicationContext(), Main.class);   
            String keyIdentifer  = null;
            pass.putExtra("Involved", fireinvolvedsave);
    // Getting an error here: fireinvolvedsave cannot be resolved to a variable
            startActivity(pass);}}}

help — I have 7 activities of data I need to pass back to the main activity so I can place them into an email — kinda stuck right here

Answer 1

fireinvolvedsave can’t be seen because you declared it as a local variable a different method to the one you are reading it in; you need to declare it as a field of the activity using, eg, public String etc, after public class FireScreen ... {

---

public class FireScreen extends Activity implements OnClickListener
{
  private String fireinvolvedsave;

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

    EditText FIinvolvedtext = (EditText) findViewById(R.id.FIinvolvedtext);
    fireinvolvedsave = FIinvolvedtext.getText().toString();

    // rest of original code for onCreate goes here
  }


  public void onClick(View v)
  {
    // original code etc

    Intent pass = new Intent(getApplicationContext(), Main.class);   

    // this now has a value:
    pass.putExtra("Involved", fireinvolvedsave);
    startActivity(pass);
  }
}

Try something like

Intent myIntent = getIntent();
String strText = myIntent.getStringExtra("Involved");

and then

emailIntent.putExtra(EXTRA_TEXT, strText);
