我是 eclipse 的新手，我有一个项目可以使用 textview 添加和编辑姓名、年龄等，可能与联系人列表相同

parseint在这里我有 3 个类.. 1 个用于 arraylist 数据 1 个用于视图持有者，最后一个是我的活动问题是当我使用 parseint 作为年龄时.. 如果我使用字符串，当我使用 a和之后没有任何问题我填写姓名和年龄，然后按添加按钮，它显示应用程序已意外停止..

这是一些代码

public void Save(View view){
        @SuppressWarnings("unchecked")

        ArrayAdapter<Data> adapter = (ArrayAdapter<Data>)getListAdapter();

        EditText Name = (EditText)findViewById(R.id.Name);
        EditText Age = (EditText)findViewById(R.id.Age);

        String name = Name.getText().toString();
        int age = Integer.parseInt(Age.getText().toString());

        if (edit)
        {
            Data temp = adapter.getItem(position);
            temp.setData(name,age);
        }
        else
        {
            Data temp = new Data(name, age);
            friends.add(temp);
        }
        viewflipper.showNext();
    }

如果我使用字符串它的工作，int age = Integer.parseInt(Age.getText().toString());我不知道该代码有什么问题并且我已经将我的文本视图的 xml 更改为这个 android:inputType="number" >，但它也是同样的错误

采用

 textview.setText(Integer.toString(age));

我认为您试图将文本设置为 int。我的意思是你试过textview.setText(age);

所以你必须使用字符串，比如textview.setText(" "+age);
