我正在尝试扩展布局，但它对我不起作用。我在列表视图中使用了Basedapater。

int can1 = Integer.parseInt(c.getString(c.getColumnIndex("InCan")));
if (can1 < 1) {
    // ...
} else {
    View view;
    LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = inflater.inflate(R.layout.receipt, null);
    TextView textView = (TextView) view.findViewById(R.id.rcan);
    textView.setVisibility(View.GONE);
    TextView coke3 = (TextView) view.findViewById(R.id.rcoke);
    coke3.setVisibility(View.GONE);

can[i] = " Coke In Can: "+c.getString(c.getColumnIndex("InCan"));
}

你能指出我的问题是什么吗？

这是我在列表视图中使用的适配器类。希望你能帮助我。

使用下面的代码而不是您的代码。

试试这个代码

 LayoutInflater inflater = null;
 inflater= (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
 view = inflater.inflate(R.layout.other, null);
