java - android TextView Layout以编程方式

我想将TextViews右边一个对齐，左边另一个对齐，并且每一行都包含一个文本视图...
我不想使用Width:fill_parent setGravity(Gravity.Right)我正在使用背景。
这是我的代码：

LinearLayout mainChatLayout = new LinearLayout(main.this);
//ChatText.setId((int)System.currentTimeMillis());
lp = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
((android.widget.RelativeLayout.LayoutParams) lp).addRule(RelativeLayout.BELOW, recent.getId());
tv = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
//ChatText.setBackgroundColor(0xfff00000);#800080
if(recent.getId() % 2 == 0) {
    ChatText = new TextView(main.this);
    mainChatLayout.setId((int)System.currentTimeMillis());
    ChatText.setBackgroundDrawable(getResources().getDrawable(R.drawable.talk1));
    ChatText.setGravity(Gravity.RIGHT); // not working
    ChatText.setText("some text");
    ChatText.setTextColor(Color.parseColor("#333333"));
    ChatText.setPadding(0, 10, 20, 10);
}
else{
    ChatText = new TextView(main.this);
    mainChatLayout.setId((int)System.currentTimeMillis());
    ChatText.setBackgroundDrawable(getResources().getDrawable(R.drawable.talk1));
    ChatText.setGravity(Gravity.LEFT);
    ChatText.setText("Time: " + System.currentTimeMillis());
    ChatText.setTextColor(Color.parseColor("#333333"));
    ChatText.setPadding(20, 10, 0, 10);
}
mainChatLayout.addView(ChatText, tv);
MainLayout.addView(mainChatLayout, lp);
recent = mainChatLayout;

最佳答案

            LinearLayout ll= /// Find Your Layout Using ID
            TextView text=new TextView(this);

现在使用LayoutParam设置“结构”。 LayoutParam将是TextView的Parent类型

    text.setLayoutParams(new LinearLayout.LayoutParams(100,100));
    ll.addView(text);
