RelativeLayout add rule “RelativeLayout.LEFT_OF” not working

Question

I have a relativeLayout like below:

Answer 1

To perform it, use predefined view ID or declare one. In values folder create ids.xml then add a Item like this:

use this id in your code where you are creating new Instance of view like this:

RelativeLayout layout=new RelativeLayout(context);

ImageView imageView = new ImageView(context);
imageView.setId(R.id.imageViewID);

RelativeLayout.LayoutParams layoutParams = new LayoutParams(50, 50);
layoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
layout.addView(imageView, layoutParams);

TextView  textView = new TextView(context);

RelativeLayout.LayoutParams textViewParams= new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
textViewParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
textViewParams.addRule(RelativeLayout.BELOW, imageView.getId());
layout.addView(nameView, nameLayoutParams);

or we can directly use this function View.generateViewId() to perform the same. Like this:

imageView.setId(View.generateViewId());
