我试图将我的一个活动中的字符串发送到该组的主要活动,但是我遇到了一个小问题。我试图在我的代码的onActivityResult部分创建一个对象(这似乎工作)。但是当尝试从getName()以外的类中访问方法时,它会发出资源未找到的异常。我确定解决方案很简单,但在对它进行了一些调查之后,它仍然无法避免。继承人代码......
MainActivity
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode)
{
case 0:
//for add activity
if(resultCode == RESULT_OK)
{
namePasser = data.getExtras().getString("tallyName").toString();
itemHm.put("item1", new Items(namePasser,1));
itemAmt++;
currItem = itemHm.get("item1");
nameView1.setText(currItem.getName());
countView1.setText(currItem.getGroup());
count1b.setVisibility(View.VISIBLE);
reduce1b.setVisibility(View.VISIBLE);
countView1.setVisibility(View.VISIBLE);
resetb.setVisibility(View.VISIBLE);
}
}
}
addActivity
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.text.Editable;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class addActivity extends Activity
{
EditText name;
String itemName;
Button next;
Intent data;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.addactivityxml);
Button next = (Button) findViewById(R.id.button1);
next.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view)
{
name = (EditText)findViewById(R.id.newitemtxt);
itemName = name.getText().toString();
data = new Intent();
data.putExtra("tallyName", itemName);
setResult(RESULT_OK, data);
finish();
}
});
}
}
项目类
public class Items
{
int id = 0;
int group = 0;
String name = "";
int count = 0;
public Items(String name, int count)
{
this.count = count;
this.name = name;
}
public Items(String name, int count, int group)
{
this.group = group;
this.name = name;
this.count = count;
}
public Items(int id, String name, int group)
{
this.id = id;
this.group = group;
this.name = name;
}
public String getName()
{
return name;
}
public int getCount()
{
return count;
}
public int addCount()
{
count++;
return count;
}
public int reduceCount()
{
if(count > 0)
{
count--;
return count;
}
return count;
}
public int resetCount()
{
count = 0;
return count;
}
public void setGroup(int group)
{
this.group = group;
}
public int getGroup()
{
return group;
}
}
当我运行时,数据本身正在传递给onActivity Result nameView1.setText(currItem.getName()); 没问题,
但是在试图跑的时候 countView1.setText(currItem.getGroup()); 这就是问题发生的时候
哦!继承错误日志

我也很确定项目的文本框没有任何问题,因为我可以在ActivityResult之外为其分配其他值 在此先感谢任何可以帮助我解决这个问题的人=)
答案 0 :(得分:2)
countView1.setText(currItem.getGroup());
可能是这行有问题,getGroup
返回int
类型,它认为是字符串id,所以你需要检查返回值是否是有效的字符串id < / strong>,如果您只想设置getGroup
返回的内容,请尝试使用:
countView1.setText(currItem.getGroup()+"");
答案 1 :(得分:0)
name = (EditText)findViewById(R.id.newitemtxt);
从点击事件中删除此行,然后在下面添加按钮= ...
并尝试..
