将按钮放置在两个不同的LinearLayouts上

// 获取LinearLayout对象
LinearLayout linearLayout1 = findViewById(R.id.linearLayout1);
LinearLayout linearLayout2 = findViewById(R.id.linearLayout2);

// 创建按钮对象
Button button1 = new Button(this);
Button button2 = new Button(this);

// 设置按钮文本
button1.setText("Button 1");
button2.setText("Button 2");

// 将按钮添加到LinearLayout中
linearLayout1.addView(button1);
linearLayout2.addView(button2);

// 设置按钮在LinearLayout中的布局参数
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
    LinearLayout.LayoutParams.WRAP_CONTENT,
    LinearLayout.LayoutParams.WRAP_CONTENT
);
button1.setLayoutParams(layoutParams);
button2.setLayoutParams(layoutParams);
