这是我的MainActivity文件,在这里我使用了getBox()方法,我得到'无法解决方法'错误。如何解决?
public class MainActivity extends Activity {
ArrayList<Product> products = new ArrayList<Product>();
ListAdapter boxAdapter;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fillData();
boxAdapter = new ListAdapter1(this, products);
ListView lvMain = (ListView) findViewById(R.id.lvMain);
lvMain.setAdapter(boxAdapter);
}
void fillData() {
for (int i = 1; i <= 20; i++) {
products.add(new Product("Product " + i, i * 100,
R.drawable.abc_ic_search, false));
}
}
public void showResult(View v) {
String result = "Selected Product are :";
int totalAmount=0;
for (Product p : boxAdapter.getBox()) {
if (p.box){
result += "\n" + p.name;
totalAmount+=p.price;
}
}
Toast.makeText(this, result+"\n"+"Total Amount:="+totalAmount, Toast.LENGTH_LONG).show();
}
}
这是我的ListAdapter1 java文件 - 这里我定义了方法fox getBox()
这里我已经为getBox定义了methode =
ArrayList<Product> getBox() {
ArrayList<Product> box = new ArrayList<Product>();
for (Product p : objects) {
if (p.box)
box.add(p);
}
return box;
}
请清除此错误并解释为什么我的代码中出现了这样的错误。
答案 0 :(得分:0)
使用ListAdapter boxAdapter;
ListAdapter1 boxAdapter;
行
