[英]Android - The constructor is undefined error
I want to pass data in fragment activity to another class. 我想将片段活动中的数据传递给另一个类。 But, it makes an error that "The constructor Intent(new View.OnClickListener(){}, Class) is undefined".
但是,这会导致“未定义构造函数Intent(new View.OnClickListener(){},Class)”的错误。
with this code 用这个代码
'Intent intent = new Intent(this, WebSocket_Connector.class);'
Here is the code..how can I pass the 'id' string value? 这是代码。我如何传递“ id”字符串值?
public class Myoffers_Fragment extends Fragment {
private final WebSocketConnection mConnection = new WebSocketConnection();
public static Fragment newInstance(Myoffers context, int pos, float scale)
{
Bundle b = new Bundle();
b.putInt("pos", pos);
b.putFloat("scale", scale);
return Fragment.instantiate(context, Myoffers_Fragment.class.getName(), b);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
return null;
}
LinearLayout l = (LinearLayout) inflater.inflate(R.layout.mf, container, false);
int pos = this.getArguments().getInt("pos");
TextView tv = (TextView) l.findViewById(R.id.text);
tv.setText("Product " + pos);
ImageButton product_photo = (ImageButton) l.findViewById(R.id.myoffer_image);
if (pos == 0) {
product_photo.setImageResource(R.drawable.myoffers_0);
product_photo.setOnClickListener(new ImageButton.OnClickListener(){
public void onClick(View v){
String id1 = "Product0";
Intent intent = new Intent(this, WebSocket_Connector.class);
intent.putExtra("KeyToAccessData", id1);
startActivity(intent);
Log.d(TAG, "Current product is : " + id1);
Log.d(TAG, id1 + "is sent to server!");
}
});
}
one of the Intent constrcutor takes a paramter a Context
and a .class
object. Intent构造函数之一采用
Context
和.class
对象作为参数。 So your this
has to be a valid context or an Activity. 因此,
this
必须是有效的上下文或活动。 From the documentation: 从文档中:
Parameters 参量
packageContext
A Context of the application package implementing this class. packageContext
实现此类的应用程序包的上下文。 cls
The component class that is to be used for the intent. cls
用于意图的组件类。 Change 更改
new Intent(this, WebSocket_Connector.class);
with 与
new Intent(getActivity(), WebSocket_Connector.class);
你为什么不试试这个
Intent intent = new Intent(Myoffers_Fragment.this, WebSocket_Connector.class);
