将按钮动态添加到带有ID的线性布局？

Question

是否有任何方法动态地添加新的按钮，以其独特的ID线性布局。考虑一个预定义的按钮来执行此操作。

Answer 1

LinearLayout row = new LinearLayout(this); 
    row.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); 
Button btnTag = new Button(this); 
     btnTag.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 
     btnTag.setText("Button 1"); 
     btnTag.setId(1); 
     row.addView(btnTag); 
layout.addView(row); 

Answer 2

是的，你可以动态地添加按钮到线性布局。

对于如：

LinearLayout layout = new LinearLayout(this); 
layout.setLayoutParams(new AbsListView.LayoutParams(AbsListView.LayoutParams.WRAP_CONTENT,AbsListView.LayoutParams.WRAP_CONTENT)); 
layout.setId(5000); 

Random random = new Random(); 
//Five button 
for(int i=0;i<5;i++) 
{ 
Button button = new Button(this); 
button.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 
button.setText("Button"); 
button.setId(random.nextInt(5)); //generate unique number between 0 to 4 and set it as id 
layout.addView(button); 
}
