java实现 ConstraintLayout 两个子view实现约束

以下是Java实现ConstraintLayout两个子view实现约束的代码示例：

// 导入必要的包
import androidx.constraintlayout.widget.ConstraintLayout;
import androidx.constraintlayout.widget.ConstraintSet;

// 获取ConstraintLayout对象
ConstraintLayout constraintLayout = findViewById(R.id.constraint_layout);

// 创建两个子view
View view1 = new View(this);
View view2 = new View(this);

// 设置两个子view的id
view1.setId(View.generateViewId());
view2.setId(View.generateViewId());

// 将两个子view添加到ConstraintLayout中
constraintLayout.addView(view1);
constraintLayout.addView(view2);

// 创建一个ConstraintSet对象
ConstraintSet constraintSet = new ConstraintSet();

// 将两个子view与父布局进行约束
constraintSet.connect(view1.getId(), ConstraintSet.TOP, ConstraintSet.PARENT_ID, ConstraintSet.TOP);
constraintSet.connect(view1.getId(), ConstraintSet.START, ConstraintSet.PARENT_ID, ConstraintSet.START);
constraintSet.connect(view2.getId(), ConstraintSet.TOP, ConstraintSet.PARENT_ID, ConstraintSet.TOP);
constraintSet.connect(view2.getId(), ConstraintSet.END, ConstraintSet.PARENT_ID, ConstraintSet.END);

// 将两个子view进行约束
constraintSet.connect(view1.getId(), ConstraintSet.END, view2.getId(), ConstraintSet.START);

// 应用约束
constraintSet.applyTo(constraintLayout);
