我正在尝试自定义列表视图，以便在按Enter键时，新项目可以自动添加到列表视图中。这是我第一次做到这一点并得到了bug。我并不擅长阅读LogCat，但我预测问题来自于无法对我在自定义列表视图布局中创建的TextView进行夸大。请帮我找出问题!!!谢谢
这是我的主要活动

内容是我创建的类，我认为它不会导致错误
这是我的CustomAdapter
package com.example.auto_multi_listview;

public class MyOwnAdapter extends ArrayAdapter<Content> {
private Activity context;
private int layoutId;
private ArrayList<Content> list;
public MyOwnAdapter(Activity context, int layoutId, ArrayList<Content> list) {
super(context, layoutId, list);
this.context = context;
this.layoutId = layoutId;
this.list = list;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View customView = inflater.inflate(R.layout.custom_listview, parent, false);
ImageView image = (ImageView) customView.findViewById(R.id.imageView1);
TextView line1 = (TextView) customView.findViewById(R.id.textView1);
TextView line2 = (TextView) customView.findViewById(R.id.textView2);
Content content = list.get(position);
image.setImageResource(content.getImage());
line1.setText(content.getLine1()+"");
line2.setText(content.getLine2()+"");
return customView;
}
}
