TextView programmatically Android

Question

I have some problems with textView software. I really don't know how to solve it.

Problems:

-Fields, I do not want my TextView to snap to each other.

- the text is not centered in the drawing, as in the title

“I want Nickname's messages aligned right and Nick's messages aligned left.”

For this, I have two functions:

private void appendSenderText(String message) {

        TextView msg = new TextView(ChatActivity.this);
        msg.setBackgroundResource(R.drawable.rectangle);
        msg.setText(message);
        msg.setPadding(10, 10, 10, 10);
        msg.setTextColor(getResources().getColor(R.color.white));
        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT, Gravity.LEFT);
        params.setMargins(10, 10, 10, 10);
        msg.setLayoutParams(params);
        LinearLayout chat = (LinearLayout) findViewById(R.id.chatLayout);
        chat.addView(msg);  
    }

    private void appendReceiverText(String message) {

        TextView msg = new TextView(ChatActivity.this);
        msg.setBackgroundResource(R.drawable.rectangle);
        msg.setText(message);
        msg.setPadding(10, 10, 10, 10);
        msg.setTextColor(getResources().getColor(R.color.white));
        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT, Gravity.RIGHT);
        params.setMargins(10, 10, 10, 10);
        msg.setLayoutParams(params);
        LinearLayout chat = (LinearLayout) findViewById(R.id.chatLayout);
        chat.addView(msg);  
    }

It seems that it is not working. I also checked that the functions are correctly called. I noticed that in my XML file for the header, I specified layout_gravity, not gravity.

EDIT: I used ListView, as you said, everything works fine, but I still have this problem with text not centered, although I used. msg.setGravity(gravity.CENTER); Maybe my drawable has a problem.

drawable.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">

   <stroke
     android:width="1px"

, texView.

Message message = (Message) this.getItem(position);

        ViewHolder holder; 
        if(convertView == null)
        {
            holder = new ViewHolder();
            convertView = LayoutInflater.from(mContext).inflate(R.layout.sms_row, parent, false);
            holder.message = (TextView) convertView.findViewById(R.id.message_text);
            convertView.setTag(holder);
        }
        else
            holder = (ViewHolder) convertView.getTag();

        holder.message.setText(message.getMessage());
        holder.message.setTextSize(17);
        holder.message.setGravity(Gravity.CENTER);
        LayoutParams lp = (LayoutParams) holder.message.getLayoutParams();
        if(message.isMine())
        {
            holder.message.setBackgroundResource(R.drawable.rectangle);
            lp.gravity = Gravity.LEFT;
        }
        else
        {
            holder.message.setBackgroundResource(R.drawable.rectangledest);
            lp.gravity = Gravity.RIGHT;
        }
        holder.message.setLayoutParams(lp);
        holder.message.setTextColor(Color.WHITE);   

        return convertView;
    }

, :

private void appendSenderText(String message) {

    TextView msg = new TextView(ButtonsActivity.this);
    msg.setBackgroundResource(R.drawable.rectangle);
    msg.setText(message);
    msg.setPadding(10, 10, 10, 10);
    msg.setTextColor(getResources().getColor(R.color.white));
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
    params.setMargins(5, 15, 0, 0);
    params.gravity = Gravity.LEFT;
    msg.setLayoutParams(params);
    msg.setGravity(Gravity.CENTER);
    LinearLayout chat = (LinearLayout) findViewById(R.id.chatLayout);
    chat.addView(msg);  
}

private void appendReceiverText(String message) {

    TextView msg = new TextView(ButtonsActivity.this);
    msg.setBackgroundResource(R.drawable.rectangle);
    msg.setText(message);
    msg.setPadding(10, 10, 10, 10);
    msg.setTextColor(getResources().getColor(R.color.white));
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
    params.setMargins(0, 15, 5, 0);
    params.gravity = Gravity.RIGHT;
    msg.setLayoutParams(params);
    msg.setGravity(Gravity.CENTER);
    LinearLayout chat = (LinearLayout) findViewById(R.id.chatLayout);
    chat.addView(msg);  
}

TextView, TextView LinearLayout, TextView LinearLayout.

, LinearLayout FrameLayout.
