How to set text in textview from array

Question

I am trying to get the values I have in an array to a text view, I am using a ViewFlipper and I would like to change the textview at the same time the image changes.

for (int i = 0; i < imagens.length && i < categories.length; i++) {
    ImageView imageView = new ImageView(this);
    imageView.setImageResource(imagens[i]);
    simpleViewFlipper.addView(imageView);

    info_text3.setText(Arrays.toString(categories));
}

Animation in = AnimationUtils.loadAnimation(this, android.R.anim.slide_in_left);
Animation out = AnimationUtils.loadAnimation(this, android.R.anim.slide_out_right);
simpleViewFlipper.setInAnimation(in);
simpleViewFlipper.setOutAnimation(out);
simpleViewFlipper.setFlipInterval(5000);
simpleViewFlipper.setAutoStart(true);

The image part is working and setting the text to the textview is also working, the problem is that the textview is static and that the text in the text view is the entire array and I just want one value, I was thinking linking the array with the 'i' from the for sentence, how can I do this?

Why would you need to convert array into string? just pass the array index of which you want to set in textView — Abdul Kawee

You can directly access arrays values at any index

info_text3.setText(categories[i]);

1. Create a layout with an image and a text view as mentioned below:

custom_view

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="@dimen/element_spacing"
        android:text="Text" />

    <ImageView
        android:id="@+id/image"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/yourimage" />

</LinearLayout>

2. Inflate that layout

View customView = activity.getLayoutInflater().inflate(R.layout.custom_view, null);

3. Add custom view to viewflipper.

simpleViewFlipper.addView(customView);

FINAL CODE

for (int i = 0; i < imagens.length && i < categories.length; i++) {
    View customView = context.getLayoutInflater().inflate(R.layout.custom_view, null);
    TextView info_text3 = customView.findViewById(R.id.text);
    ImageView imageView = customView.findViewById(R.id.image);
    imageView.setImageResource(imagens[i]);
    simpleViewFlipper.addView(customView);

    info_text3.setText(categories[i]);
}

I've tried this before, but it wasn't working or at least I though so, it does work but the last value stays there and I don't even get to see the others, how can I make it change at the same time as the image?

Are you using this in adapter? Please share the full code to identify last value issue

alb Over a year ago

yes, I'm doing that right now (see anddevmanu answer) but the textview isn't showing up only the image, I didn't noticed you'de edited your code

PEHLAJ Over a year ago

Please see the updated code (step by step). You can directly run the FINAL CODE in the answer

It doesn't let inflate the layout, it says 'Cannot resolve method getLayoutInflater()'
