在GridView中找不到错误原因

Question

我正在Android开发者网页上测试一个GridView示例，但是我得到了一些错误，尽管我已经复制并粘贴了代码！下面链接到示例。我能做错什么？提供一些帮助！谢谢！

错误消息：此行有多个标记      - OnItemClickListener无法解析为某种类型      - AdapterView类型中的方法setOnItemClickListener（AdapterView.OnItemClickListener）不是      适用于参数（new OnItemClickListener（）{}）

GridView example

编辑：所有代码

MainActivity.java

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.GridView;
import android.widget.Toast;

public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    GridView gridview = (GridView) findViewById(R.id.gridview);
    gridview.setAdapter(new ImageAdapter(this));

    gridview.setOnItemClickSelectedListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            Toast.makeText(MainActivity.this, "" + position, Toast.LENGTH_SHORT).show();
        }
    });

}
}

ImageAdapter.java

 import android.content.Context;
 import android.view.View;
 import android.view.ViewGroup;
 import android.widget.BaseAdapter;
 import android.widget.GridView;
 import android.widget.ImageView;

public class ImageAdapter extends BaseAdapter {
private Context mContext;

public ImageAdapter(Context c) {
    mContext = c;
}

public int getCount() {
    return mThumbIds.length;
}

public Object getItem(int position) {
    return null;
}

public long getItemId(int position) {
    return 0;
}

// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView;
    if (convertView == null) {  // if it's not recycled, initialize some attributes
        imageView = new ImageView(mContext);
        imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(8, 8, 8, 8);
    } else {
        imageView = (ImageView) convertView;
    }

    imageView.setImageResource(mThumbIds[position]);
    return imageView;
}

// references to our images
private Integer[] mThumbIds = {
        R.drawable.sample_0, R.drawable.sample_1,
        R.drawable.sample_2, R.drawable.sample_3,
        R.drawable.sample_4, R.drawable.sample_5,
};
}

Answer 1

您可以尝试此gridView.setOnItemSelectedListener

这对我来说很好用

Answer 2

您可以导入以下类吗？

import android.widget.GridView;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.view.View;

然后保存文件。一个。相当于日食将是ctrl shift o然后是ctrl s

Answer 3

您需要导入此

import android.widget.GridView;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.view.View;

       or 

使用BaseAdapter
