开发环境：AndroidStudio2.1.2+gradle-2.10
涉及知识：1.沉浸式状态栏，2.单位精度计算(价格)，3.List之Iterator。
部分代码：
public class MainActivity extends AppCompatActivity implements FoodAdapter.FoodActionCallback { private ListView listView; private TextView goods_all_pricetv; private TextView good_numtv; private List<FoodModel> list; private List<FoodModel> selectList = new ArrayList<>(); private FoodAdapter adapter = null; @Override protected void onCreate(@Nullable final Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //沉浸式状态栏 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //透明状态栏 getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //透明导航栏 getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); } listView = (ListView) findViewById(R.id.listView); goods_all_pricetv = (TextView) findViewById(R.id.goods_all_pricetv); good_numtv = (TextView) findViewById(R.id.good_numtv); findViewById(R.id.goods_submit_tv).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (null != selectList && selectList.size() > 0) { Toast.makeText(MainActivity.this, "你一共加入购物车" + good_numtv.getText() + "份商品,总价格为：" + goods_all_pricetv.getText(), Toast.LENGTH_SHORT).show(); } else { Toast.makeText(MainActivity.this, "你的购物车为空", Toast.LENGTH_SHORT).show(); } } }); initData(); } private void initData() { list = AppConfig.factoryFoods(); adapter = new FoodAdapter(this, list, this); listView.setAdapter(adapter); } //添加商品动画 @Override public void addAction(View view, int item) { ShoppingCartAnimationView shoppingCartAnimationView = new ShoppingCartAnimationView(this); int position[] = new int[2]; view.getLocationInWindow(position); shoppingCartAnimationView.setStartPosition(new Point(position[0], position[1])); ViewGroup rootView = (ViewGroup) this.getWindow().getDecorView(); rootView.addView(shoppingCartAnimationView); int endPosition[] = new int[2]; good_numtv.getLocationInWindow(endPosition); shoppingCartAnimationView.setEndPosition(new Point(endPosition[0], endPosition[1])); shoppingCartAnimationView.startBeizerAnimation(); FoodModel model = list.get(item); model.setNum(model.getNum() + 1); adapter.notifyDataSetChanged(); calculatePrice(); } //减少商品 @Override public void reduceGood(int position) { FoodModel model = list.get(position); model.setNum(model.getNum() - 1); adapter.notifyDataSetChanged(); calculatePrice(); } //购物车份数+总价格计算 private void calculatePrice() { selectList.clear(); double price = 0; int num = 0; Iterator<FoodModel> iterator = list.iterator(); while (iterator.hasNext()) { FoodModel model = iterator.next(); if (model.getNum() != 0) { selectList.add(model); price += model.getPrice() * model.getNum(); num += model.getNum(); } } goods_all_pricetv.setText("￥" + adapter.priceResult(price) + "元"); good_numtv.setText(num + ""); }}关于怎么在Android应用中添加一个添加物品动画就分享到这里了，希望以上内容可以对大家有一定的帮助，可以学到更多知识。如果觉得文章不错，可以把它分享出去让更多的人看到。
