Android speech to text using listview

Question

The code below is used to convert speech to text on an android app. This code works when the speech button is pressed and whatever you say is transferred into text. When the speech function closes, the the text is showing. If you hit the speech button again, the previous text is cleared and the new text shows on the page. What i want to do is everytime i click the speak button, i want to show the word on the page.. then if i click the speak button again, i want the next word to appear under the first word in a list format. i am looking to use listview but am struggling. here is the original code and the code i am trying to write to make it a listview. can anyone assist?

XML:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"

<ImageButton
    android:id="@+id/btnSpeak"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"

    android:layout_marginTop="10dp"
    android:contentDescription="@string/speak"
    android:src="@android:drawable/ic_btn_speak_now" />

<TextView

            ArrayList<String> text = data
                    .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

            txtText.setText(text.get(0));
        }
        break;
    }

    }

Answer 1

In your onActivityResult, you are overriding your TextView with the first word only(index 0). You must iterate through the String array list like so:

    String words = "";
    for ( String word : text ) {
        words += " " + word;
    }
    txtText.setText(words);

And here's a nice article to help you implement your ListView: ListView tutorial

So now when you figured that out you add the words value in the listview.

Hope this helps, Cheers
