Buttons are not adding as per the Flow layout behaviour

[venkymsnv]

I used Flowlayout in my application. Below is my code

<com.wefika.flowlayout.FlowLayout android:id="@+id/flow" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="start" />

then I adding the childview as buttons dynamically.Below is the code
`FlowLayout ll = (FlowLayout)layout.findViewById(R.id.flow);
for (int i = 0; i <= btnList.size; i++) {

          final Button btnTag = new Button(MainActivity.this); 
         btnTag.setId(3000 + i);
        FlowLayout.LayoutParams layoutParams = new FlowLayout.LayoutParams(
               FlowLayout.LayoutParams.WRAP_CONTENT,FlowLayout.LayoutParams.WRAP_CONTENT);
          layoutParams.setMargins(7,7,7,7);
          btnTag.setTextColor(Color.BLACK);

          btnTag.setText("#"+btnList.get(i).toString());
          ll.addView(btnTag,layoutParams)
      }`

1. Button width is not changing dynamically as per the text
2. How to decrease Padding between button border and its text.
   How to resolve the above issues?
   Below is my screenshot
