Problem: I cannot pass the rating value/data from the rating bar to another intent. It only shows me this instead of the value/data from the rating bar.
Rating: MainActivity@79b604
I think the error is that it did not properly get the value from the rating bar or it did not pass the value correctly. Here is my code:
MainActivity.java
public class MainActivity extends AppCompatActivity {
String rating_float = "0.0";
private TextView txtRatingValue;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RatingBar ratingBar = (RatingBar) findViewById(R.id.ratingBar);
ratingBar.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {
@Override
public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
rating_float = String.valueOf(rating);
}
});
}
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
Context context = getApplicationContext();
CharSequence text = "";
Intent intent_rating = new Intent(this, SecondActivity.class);
intent_rating.putExtra("rating_float", toString());
startActivity(intent_rating);
return super.onOptionsItemSelected(item);
}}
SecondActivity.java
public class SecondActivity extends AppCompatActivity {
private TextView Msg;
String PassedValue = null;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
PassedValue = getIntent().getStringExtra("rating_float");
Msg = (TextView) findViewById(R.id.Msg);
Msg.setText("Dimension: 479\nFormat: JPEG\nSize: 360x360\nRating: " + PassedValue);
}
Questions:
That is because you pass the result of MainActivity.toString() to your second activity
Instead of
intent_rating.putExtra("rating_float", toString());
you should presumably write
intent_rating.putExtra("rating_float", this.rating_float);
You are receiving it well but not sending what you have to.
Just use this:
intent_rating.putExtra("rating_float", rating_float);
First you need to save your value into the putExtra
of the intent you use to go to the another activity
intent_rating.putExtra("rating_float", rating_float);
to get the value in the SecondActivity you just need to do this wherever you need the value.
Intent iin= getIntent();
Bundle b = iin.getExtras();
if(b!=null)
{
String rating_value =(String) b.get("rating_float");
}
Simple and Clear Solution
//1stActivity
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
float rating = rate.getRating();
Intent intent = new Intent(ContactActivity.this,RatingIntentSOF.class);
Bundle bundle = new Bundle();
bundle.putFloat("totalRating",rating);
intent.putExtras(bundle);
startActivity(intent);
//2nd Activity, get the data of 1st Activity.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rating_intent_sof);
TextView textView = (TextView) findViewById(R.id.text);
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
float totalRating = bundle.getFloat("totalRating");
textView.setText(String.valueOf(totalRating));
