Java Gridview onclick侦听器不工作

我正在使用布局的gridview，它在列表中的grid view项之后不工作，它在logcat错误中显示“throwIndexOutOfBoundsException”。如果我使用toast，则没有onclick函数，如果我为下一个活动提供onlick函数，则它不工作

Gridviewadapter.java

public class GridviewAdapter extends BaseAdapter
{
    private ArrayList<String> listginfy;
    private ArrayList<Integer> listimage;
    private Activity activity;

    public GridviewAdapter(GinfyActivity ginfyActivity,ArrayList<String> listginfy, ArrayList<Integer> listimage) {
        super();
        this.listginfy = listginfy;
        this.listimage = listimage;
        this.activity = (Activity) ginfyActivity;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return listginfy.size();
    }

    @Override
    public String getItem(int position) {
        // TODO Auto-generated method stub
        return listginfy.get(position);
    }

    public int getItemId() {
        // TODO Auto-generated method stub
        return 0;
    }

    public static class ViewHolder
    {
        public ImageView imgViewGinfy;
        public TextView txtViewTitle;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        ViewHolder view;
        LayoutInflater inflator = activity.getLayoutInflater();

        if(convertView==null)
        {
            view = new ViewHolder();
            convertView = inflator.inflate(R.layout.gridview_row, null);

            view.txtViewTitle = (TextView) convertView.findViewById(R.id.textView1);
            view.imgViewGinfy = (ImageView) convertView.findViewById(R.id.imageView1);

            convertView.setTag(view);
        }
        else
        {
            view = (ViewHolder) convertView.getTag();
        }

        view.txtViewTitle.setText(listginfy.get(position));
        view.imgViewGinfy.setImageResource(listimage.get(position));

        return convertView;
    }

    @Override
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return 0;
    }


}

更换

mAdapter = results.get(position);

                switch(mAdapter.getItemId())

你的代码中有很多错误。。（如布局中的android:clickable=“True”删除该选项）

为了进行测试，请将代码替换为：

// Implement On Item click listener
        gridView.setOnItemClickListener(new OnItemClickListener() 
        {
            @Override
            public void onItemClick(AdapterView<?> a, View v, int position, long id) {



            switch(position)
            {
            case 1:
            Intent newActivity = new Intent(GinfyActivity.this,MainActivity.class);
            startActivity(newActivity);
            break;

            case 2:
            Intent new1Activity = new Intent(GinfyActivity.this,AndroidTabLayoutActivity.class);
            startActivity(new1Activity);
            break;
            default:
                Toast.makeText(GinfyActivity.this, "Wrong Input", Toast.LENGTH_LONG).show();
                }
        }
    });

适配器的getItemId始终返回0

我一直在用这样的东西。在你的情况下，这应该是有效的
