在ScrollView内的垂直LinearLayout中确定孩子的响应高度

ScrollView scrollView = new ScrollView(context);
LinearLayout linearLayout = new LinearLayout(context);
linearLayout.setOrientation(LinearLayout.VERTICAL);
scrollView.addView(linearLayout);

// 第一个孩子视图
View child1 = new View(context);
LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 200);
child1.setLayoutParams(params1);
linearLayout.addView(child1);

// 第二个孩子视图
View child2 = new View(context);
LinearLayout.LayoutParams params2 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 300);
child2.setLayoutParams(params2);
linearLayout.addView(child2);

// 第三个孩子视图
View child3 = new View(context);
LinearLayout.LayoutParams params3 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
child3.setLayoutParams(params3);
linearLayout.addView(child3);
