How I can create buttons one next to the other inside Relativelayout usigin Java code?

Question

I am creating many button from JSON using java code

 Relativelayout rl = (Relativelayout) findById(R.id.layout_productos); ... JSONArray jsonArray = new JSONArray(tmp.getString("productos")); Button bt[] = new Button[jsonArray.length()]; for (int i = 0; i < jsonArray.length(); i ++){ final float scale = getResources().getDisplayMetrics().density; int padding_40dp = (int) (40 * scale + 0.5f); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, padding_40dp); bt[i] = new Button(DetalleServicioActivity.this); bt[i].setText(jsonArray.getJSONObject(i).getString("nombre")); bt[i].setTag(jsonArray.getJSONObject(i).getString("id_producto")); bt[i].setTextColor(Color.parseColor("#FFFFFF")); bt[i].setBackgroundColor(Color.parseColor("#D8D8D8")); bt[i].setLayoutParams(params); bt[i].setEnabled(false); bt[i].setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { } }); rl.addView(bt[i]); }

inside Relativelayout

 <RelativeLayout android:id="@+id/layout_productos" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="10dp" > </RelativeLayout>

The problem is when is run the app, the buttons are created one upon another one.

2 button (Chilena and cuenta rut)

But I need that they are located one next to the other and when the screen of a line jump approaches the edge to continue

How can I do that??

You might want to consider a FlowLayout instead (it's not a standard Android component -- search Google for it) — Karakuri

You need to add rule in order to have them aligned next to eachother. Rules are up to you.

params.addRule(RelativeLayout.RIGHT_OF, previousViewId);

If you want to use relativelayout, you also need to consider this and add another rule such as below etc. But this is not a good idea. Instead you can use recyclerview which has staggered options. That will be a good solution for you.
