Question

我目前正在努力设置与我在gridView中点击的项目相关的OnItemClickListener。

以下代码打印出每个项目的索引位置。但相反，我希望它开始一项新活动，具体取决于点击的项目。

    GridView gridview = (GridView) findViewById(R.id.gridView1);
    gridview.setAdapter(new CustomGridViewAdapter(this, 0, gridArray));

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

我显然需要为每个索引创建一个startActivity，但是我该如何编写代码呢？有人能指出我正确的方向吗？

你的代码

GridView gridview = (GridView) findViewById(R.id.gridView1);
gridview.setAdapter(new CustomGridViewAdapter(this, 0, gridArray));

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

        // function call the activity according to index
        startActivity(position); 
    }
});

功能启动活动

public void startActivity(int index)
    {
        if(index==0)
        {
               //startFirstActivity
        }
        else if(index==1)
        {
               //startSecondActivity
        }
        //so on upto the number of item you have
    }

用gridArray索引的startActivity替换toast消息
