本人最近开发一款订餐应用，有一个是关于订餐数量的，本来打算用的是listview，但是那里的listview没有学会，在网上也没有找到好的代码，于是博主最近就直接用的动态添加组件了，跟大家分享一下，一般情况下如果是动态添加组件，首先我们可以在最原始xml文件中有一个最基本的布局，比如是linelayout此时我们可以可以在java代码中获取这个布局的id值
private LinearLayout shopinfo_content;shopinfo_content=(LinearLayout)findViewById(R.id.shopinfo_content);在得到id后，比如我用的foods之中存储用户所买的所有数据，那么我们就可以动态生成一个相当于listview的表格了，
private void setshop(){ shopinfo_content.removeAllViews();//移除所有组件 用以界面刷新 LinearLayout line=new LinearLayout(ShoppingActivity.this); line.setClickable(true); line.setOrientation(LinearLayout.HORIZONTAL); final TextView shop_name=new TextView(ShoppingActivity.this);//名称 shop_name.setText("名称"); shop_name.setTextSize(18); shop_name.setTextColor(Color.BLACK); line.addView(shop_name); final TextView shop_price=new TextView(ShoppingActivity.this);//单价 shop_price.setText(" 单价"); shop_price.setTextSize(18); shop_price.setTextColor(Color.BLACK); line.addView(shop_price); final TextView shop_number=new TextView(ShoppingActivity.this);//数量 shop_number.setText(" 数量"); shop_number.setTextSize(18); shop_number.setTextColor(Color.BLACK); line.addView(shop_number); final TextView shop_thing=new TextView(ShoppingActivity.this);//操作 shop_thing.setText(" 操作"); shop_thing.setTextSize(18); shop_thing.setGravity(Gravity.RIGHT);//居右对齐 shop_thing.setTextColor(Color.BLACK); line.addView(shop_thing); shopinfo_content.addView(line); for(int i=0;i<foods.size();i++){ LinearLayout line1=new LinearLayout(ShoppingActivity.this); line1.setClickable(true); line1.setOrientation(LinearLayout.HORIZONTAL); final TextView lunch_name=new TextView(ShoppingActivity.this); lunch_name.setText(foods.get(i).getName()); lunch_name.setTextSize(18); lunch_name.setTextColor(Color.BLACK); line1.addView(lunch_name); final TextView lunch_price=new TextView(ShoppingActivity.this); //System.out.println("价格"+foods.get(i).getPrice()); String text_price=new String(); text_price=foods.get(i).getPrice()+" "; lunch_price.setText(text_price); lunch_price.setTextSize(18); lunch_price.setTextColor(Color.BLACK); line1.addView(lunch_price); final TextView lunch_reduce=new TextView(ShoppingActivity.this); lunch_reduce.setId(i); lunch_reduce.setBackgroundResource(R.drawable.reduce); lunch_reduce.setHeight(18); lunch_reduce.setWidth(18); line1.addView(lunch_reduce); lunch_reduce.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { int i=lunch_reduce.getId();//获取当前的组件id 用于辨识组件 int number=foods.get(i).getCount()-1; foods.get(i).setCount(number); } }); final TextView lunch_number=new TextView(ShoppingActivity.this); String text_number=new String(); text_number=" "+foods.get(i).getCount()+" "; lunch_number.setText(text_number); lunch_number.setTextSize(18); lunch_number.setTextColor(Color.BLACK); line1.addView(lunch_number); final TextView lunch_add=new TextView(ShoppingActivity.this); lunch_add.setId(20+i); lunch_add.setBackgroundResource(R.drawable.add); lunch_add.setHeight(18); lunch_add.setWidth(18); line1.addView(lunch_add); lunch_add.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { int i=lunch_add.getId()-20;//获取当前的组件id 用于辨识组件 int number=foods.get(i).getCount()+1; foods.get(i).setCount(number); } }); final TextView lunch_delete=new TextView(ShoppingActivity.this); lunch_delete.setId(40+i); lunch_delete.setText(" 删除"); lunch_delete.setGravity(Gravity.RIGHT);//居右对齐 lunch_delete.setTextSize(18); lunch_delete.setTextColor(Color.BLACK); line1.addView(lunch_delete); lunch_delete.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { int i=lunch_delete.getId()-40;//获取当前的组件id 用于辨识组件 foods.remove(i); } }); shopinfo_content.addView(line1); } }其中还可以对其进行监听，用不同的id进行标识，然后对其进行操作，其中的还可以刷新界面，将组件全部进行重构
