Automatic text switching using ViewFlipper in Sketchware

In Sketchware, if you want to display a list of texts one by one by automatically switching to next sentence every few seconds, then follow the steps given below;
1. Create Sketchware project, in main.xml add a LinearLayout with id linear1 , set the width and height as MATCH_PARENT. Set a image as background of linear1.
2. Add a CustomView id customview.xml. In this add a TextView textview1 , with text size 40, width and height MATCH_PARENT, and gravity:- center_horizontal, center_vertical.
3. Add a String List string_str.
4. In onCreate, one by one add sentences to this list.
5. After adding items to string_str, use add source directly block and put following code in it.
ViewFlipper viewFlipper = new ViewFlipper(this);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(20, 20, 20, 20);
layoutParams.gravity = Gravity.CENTER;
viewFlipper.setLayoutParams(layoutParams);
viewFlipper.setFlipInterval(3000);
viewFlipper.setAutoStart(true);
viewFlipper.setInAnimation(this, android.R.anim.slide_in_left);
viewFlipper.setOutAnimation(this, android.R.anim.slide_out_right);
linear1.addView(viewFlipper);
The code above creates a new ViewFlipper, sets it's LayoutParams, sets it's FlipInterval, sets it's in and out animation, and adds it to linear1.
(You can change the bolded id per the linear id you have used)
6. After this add another add source directly block and put following codes.

for (String text : string_str) {
View custom = getLayoutInflater().inflate(R.layout.customview, null);
TextView textView = custom.findViewById(R.id.textview1);
textView.setText(text);
viewFlipper.addView(custom);
}
The code above creates a View custom from CustomView customview for each String text in String list string_str. Then for each position, it gets the TextView from custom and sets it's text to the String from string_str.
7. Save and run the project. You will see the texts automatically flipping every 3000 milliseconds.
To add custom fonts to the textView, add a custom font using font manager and add set it as typeface of the TextView created in point 6 above by modifying the code as shown below.

for (String text : string_list) {
View custom = getLayoutInflater().inflate(R.layout.customview, null);
TextView textView = custom.findViewById(R.id.textview1);
textView.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/cac_champagne.ttf"), 0);
textView.setText(text);
viewFlipper.addView(custom);
}
(You can change the bolded font name per the name of the font you added to the fonts manager).
