Android: Toast won't delay on spinner

I want to delay the toast "Your message "message" is sent to "contact" to appear according to the delay the user chose in the spinner. The following codes has errors (pos), here's my code:

Handler handler = new Handler();
spinnerTimeDelay = (Spinner) findViewById(R.id.spinner_delay);
spinnerTimeDelay.setOnItemSelectedListener(this);
        ArrayAdapter<String> aa=new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,items);
        aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinnerTimeDelay.setAdapter(aa);

public void onItemSelected(AdapterView<?> parent,
            View view, int pos, long id) {
        if(FirstLoad){
            FirstLoad = false;
            return;                         
        }
Toast.makeText(parent.getContext(), "You chose " + 
                  parent.getItemAtPosition(pos).toString()+ " to delay", Toast.LENGTH_LONG);
}

        public void onNothingSelected(AdapterView<?> parent) {
          return;
        }

btnSend.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    String phoneNo = editTextRecipient.getText().toString();
                    String message = editTextNewMessage.getText().toString(); 
                    boolean split = false;

                final Toast toast = Toast.makeText(getBaseContext(), 
                         "Your message " + "\"" + message + "\"" + " is sent to " +"\""+ phoneNo+"\"", 
                          Toast.LENGTH_SHORT);1

                Runnable showToastRunnable = new Runnable() {
                  public void run() {
                      toast.show();
                  }
              };

                if (phoneNo.length()>0 && message.length()>0)  {
                    if (pos == 0) {
                          handler.postDelayed(showToastRunnable, 0);
                      }
                      else if (pos == 1) {
                          handler.postDelayed(showToastRunnable, 15000);
                      }
                      else if (pos == 2) {
                          handler.postDelayed(showToastRunnable, 30000);
                      }
                      else if (pos == 3) {
                          handler.postDelayed(showToastRunnable, 60000);
                      }
                }

                else
                    Toast.makeText(getBaseContext(), 
                        "Please enter both phone number and message.", 
                        Toast.LENGTH_SHORT).show();
            }
        });        
    }

How should I declare the pos?

回答1:

Just declare one int variable (int count=0) globally and store position of selected spinner's item (count=pos) and use that int variable in your sendButton's onClick()'s if-else conditions (if(count==1))

Try this,

private int count=0;
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
Handler handler = new Handler();
spinnerTimeDelay = (Spinner) findViewById(R.id.spinner_delay);
spinnerTimeDelay.setOnItemSelectedListener(this);
        ArrayAdapter<String> aa=new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,items);
        aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinnerTimeDelay.setAdapter(aa);

public void onItemSelected(AdapterView<?> parent,
            View view, int pos, long id) {

           count=pos;
        if(FirstLoad){
            FirstLoad = false;
            return;                         
        }
}

        public void onNothingSelected(AdapterView<?> parent) {
          return;
        }

btnSend.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    String phoneNo = editTextRecipient.getText().toString();
                    String message = editTextNewMessage.getText().toString(); 
                    boolean split = false;

                final Toast toast = Toast.makeText(getBaseContext(), 
                         "Your message " + "\"" + message + "\"" + " is sent to " +"\""+ phoneNo+"\"", 
                          Toast.LENGTH_SHORT);1

                Runnable showToastRunnable = new Runnable() {
                  public void run() {
                      toast.show();
                  }
              };

                if (phoneNo.length()>0 && message.length()>0)  {
                    if (count == 0) {
                          handler.postDelayed(showToastRunnable, 0);
                      }
                      else if (count == 1) {
                          handler.postDelayed(showToastRunnable, 15000);
                      }
                      else if (count == 2) {
                          handler.postDelayed(showToastRunnable, 30000);
                      }
                      else if (count == 3) {
                          handler.postDelayed(showToastRunnable, 60000);
                      }
                }

                else
                    Toast.makeText(getBaseContext(), 
                        "Please enter both phone number and message.", 
                        Toast.LENGTH_SHORT).show();
            }
        });        
    }
