The type new AdapterView.OnItemClickListener(){} must implement the inherited abstract method AdapterView.OnItemClickListener)
The type new AdapterView.OnItemClickListener(){} must implement the inherited abstract method AdapterView.OnItemClickListener.onItemClick(AdapterView, View, int, long)
Why i get this message when i tried to build the tutorial
package Fedail.Hello.Layout;
import android.app.Activity;
import android.os.Bundle;
import android.widget.*;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView.OnItemClickListener;
public class Layout_Feras extends Activity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this));
gridview.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView&l开发者_JAVA技巧t;?> parent, View v, int position, Long id){
Toast.makeText(Layout_Feras.this,"" + position, Toast.LENGTH_SHORT).show();
}
}
);
}
}
Change this:
public void onItemClick(AdapterView<?> parent, View v, int position, Long id)
to this:
public void onItemClick(AdapterView<?> parent, View v, int position, long id)
When overriding a super method you will have to make sure all datatypes match the original types.
Change your Long
to long
in onItemClick()
and see if that helps.
