java - 跨 Activity 传递信息的问题

Question

我想通过这个:

Intent i=new Intent(ctx,SpendingsDetails.class);
extras.putString("SpendingAmount", "1");
extras.putString("SpendingDescription","2");
extras.putString("SpendingDate","3");
i.putExtras(extras);
startActivityForResult(i,1);

获取信息的activity做以下信息..

    spendingAmount=(TextView)findViewById(R.id.spending_Sum);
spendingDetails=(TextView)findViewById(R.id.spending_Details);

Bundle extras=getIntent().getExtras();
if(extras!=null)
{
    spendingAmount.setText(extras.getString("SpendingAmount"));
    spendingDetails.setText(extras.getString("SpendingDescription"));
}

我收到一个错误，应用程序无法在第一个 Activity 屏幕上继续。我做错了什么？

Answer 1

这样使用

Intent i=new Intent(ctx,SpendingsDetails.class);
    i.putExtras("SpendingAmount", "1");
    i.putExtras("SpendingDescription","2");
    i.putExtras("SpendingDate","3");
    startActivityForResult(i,1);
