将一个button放左边另一个放右边

创建了动态linearlayout。创建了两个button：

LinearLayout layout = new LinearLayout(this);
        layout.setOrientation(LinearLayout.HORIZONTAL);
        layout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                LayoutParams.FILL_PARENT));

        TextView titleView = new TextView(this);
        titleView.setWidth(LayoutParams.WRAP_CONTENT);
        titleView.setHeight(LayoutParams.WRAP_CONTENT);
        titleView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        titleView.setText("Hallo Welt!");
        layout.addView(titleView);

        Button btnConnect = new Button(this);
        btnConnect.setText("Connect");
        layout.addView(btnConnect);

    Button btnDisconnect = new Button(this);
    btnDisconnect.setText("Disconnect");
    layout.addView(btnDisconnect);

我想将链接的button放到左角，没链接的button放到右角，不知道能不能实现？
谢谢：D

试试设置button布局

LayoutParams params;

Button btnConnect = new Button(this);
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.Left;
btnConnect.setLayoutParams(params);
...
Button btnDisconnect = new Button(this);
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.Right;
btnConnect.setLayoutParams(params);

用xml布局实现比较简单
layout.addView(btnConnect);
layout.addView(titleView);
layout.addView(btnDisconnect);

这三句代码放到最后写即可实现 不过只是从相对的左右 不是相对界面而是相对各个控件 如果要相对界面的话那就要用Framelayout或者Relatilayout了
