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时

//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，应用程序崩溃了。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。

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

想法？

Answer 1

您在致电startActivity(myIntent);

后添加以下代码

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

将它放在startActivity(myIntent);

之前

创建捆绑并发送到新活动
