您好我已经创建了一个完全基于xml的项目。我怀疑现在我将所有xml值存储在我的数组列表中。数组列表名称为mspec_List。如何解析这个数组列表值？我使用sax解析器获得了所有值。我的第一个活动显示一些图像，如果我点击该图像我想在我的下一个活动屏幕中显示段落存储在我的数组列表中的一些段落。如何在我的下一个活动中显示该段落？我创建了新类，我正在使用textview，我也希望在该textview中显示该数组列表值。请帮助我....“
我正在尝试解析该arraylist值，但它无法正常工作，请参阅下面的代码。
sdcardImages.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
Intent intent = new Intent(ParxmlActivity.this, tabview.class);
intent.putStringArrayListExtra("numbers", mspec_List);
//intent.putExtra("name",model_List.get(position).name);
startActivity(intent);
}
});

如果你有String ArrayList，你只需使用intent.putStringArrayListExtra(name, value)传递它。您可以查看我的答案here。
答案 1 :(得分：1)
tabview.class
Intent i = getIntent();
arrlist = i.getStringArrayListExtra("name");
答案 2 :(得分：0)
您可以将model_List设为静态。
