创建捆绑并发送到新活动

Question

我在一个活动中创建一个包,然后在另一个活动中提取它

这是它在主要活动中创建的时间

//Create bundle to reference values in next class
                Bundle bundle = new Bundle();
                bundle.putInt("ODD", odd);
                bundle.putInt("EVEN", even);
                bundle.putInt("SMALL", small);
                bundle.putInt("BIG", big);
                //After all data has been entered and calculated, go to new page for results
                Intent myIntent = new Intent();
                myIntent.setClass(getBaseContext(), Results.class);
                startActivity(myIntent);
                //Add the bundle into myIntent for referencing variables
                myIntent.putExtras(bundle);

然后,当我提取其他活动

//Extract the bundle from the intent to use variables
    Bundle bundle = getIntent().getExtras();
    //Extract each value from the bundle for usage
    int odd = bundle.getInt("ODD");
    int even = bundle.getInt("EVEN");
    int big = bundle.getInt("BIG");
    int small = bundle.getInt("SMALL");

当我在第二个活动中提取包时应用程序崩溃.但是当我注释掉束的提取时.该应用运行正常.所以我把它缩小到了那个范围.

我的日志猫并没有真正解释错误是什么,或者我只是不理解它

想法？

您在调用后添加以下代码startActivity(myIntent);

//Add the bundle into myIntent for referencing variables
                myIntent.putExtras(bundle);

把这个放在前面startActivity(myIntent);
