您好我想過去從一個活動到另一個使用Parcelable一個ArrayList ..的ArrayList只檢索的最後一個值
現在的問題是,當我點擊BILL,所有行被填充的最後一個值arraylist..So我想我不能夠中檢索在調用活動的整個數組列表...
下面是相關代碼..
SpinPizza.java
public class SpinPizza extends Activity{
store temp= new store();
int i=0;
ArrayList<store> B = new ArrayList<store>();
//oncreate method
int n=Integer.parseInt(edittext.getText().toString());
temp.setOrder(s.getSelectedItem().toString(), s1.getSelectedItem().toString(),n);
B.add(temp);
TextView objText=(TextView) findViewById(R.id.pl);
TextView objText1=(TextView) findViewById(R.id.pl2);
objText.setText(B.get(i).getPizzaName());
objText1.setText(temp.getPizzaSize());
i++;
});
Button next1 = (Button) findViewById(R.id.bill);
next1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), Bill.class);
myIntent.putParcelableArrayListExtra("myclass",B);
startActivityForResult(myIntent, 0);
}
});
}
Bill.java
public class Bill extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.calc);
ArrayList<store> B1 = new ArrayList<store>();
store temp1=new store();
Bundle bj=getIntent().getExtras();
B1=bj.getParcelableArrayList("myclass");
TableLayout tl = (TableLayout)findViewById(R.id.myTable);
for(int i=0;i<B1.size();i++)
{
TableRow tr = new TableRow(this);
tr.setId(100+i);
temp1=B1.get(i);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView b = new TextView(this);
b.setText(temp1.getPizzaName());
b.setId(200+i);
TextView b1 = new TextView(this);
b1.setText(temp1.getPizzaSize());
b1.setId(300+i);
TextView b2 = new TextView(this);
b2.setText(String.valueOf(temp1.getQuantity()));
b2.setId(400+i);
b.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(b);
b1.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(b1);
b2.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
tr.addView(b2);
tl.addView(tr,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}}
}
請幫助。
@ user639183我這樣做... temp在第二行創建..(請參閱代碼)...其實我發佈整個代碼...我的壞...這是迭代.. 。 – 2011-04-01 17:09:17
