public void getIntentProcess(Intent intent) {
String comment = intent.getStringExtra("comment");
int rating = Math.round(intent.getFloatExtra("rating", 0.0f));
if (comment != null) {
items.add(new CommentItems("kim78**", rating, comment, R.drawable.user1));

}
Even if you receive an intro from one activity and add it to the list view, only one is added. I hope it will be added several times
android intent
When calling startActivity(), Activity is newly called, so to implement the desired function, use startActivityForResult() when calling CommentWriterView and update the setResult() list again.
I'm not in a situation to write an example code, so try it and if you don't understand it well, I'll let you know in detail.
public class CommentWriteView extends AppCompatActivity {
EditText commentText;
RatingBar ratingBar;
Button saveButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_comment_write_view);
commentText = findViewById(R.id.editText_comment);
ratingBar = findViewById(R.id.write_ratingbar);
saveButton = findViewById(R.id.saveButton);
Button exitButton = findViewById(R.id.exitButton);
saveButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
String comment = commentText.getText().toString();
float rating = ratingBar.getRating();
intent.putExtra("comment", comment);
intent.putExtra("rating", rating);
startActivity(intent);
returnToMain();
}
});
exitButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
}
public void returnToMain() {
String comment = commentText.getText().toString();
float rating = ratingBar.getRating();
Intent intent = getIntent();
intent.putExtra("comment", comment);
intent.putExtra("rating", rating);
setResult(RESULT_OK, intent);
finish();
}
}
