Question

我正在通过此链接Android - AutoCompleteTextView only works when backspacing

实施以下代码

但是我收到了错误。我在下面发布了logcat错误：

我也创建了课程：

public class SimpleAddress {

    public SimpleAddress(String formatted_address, Double lat, Double lng) {
        // TODO Auto-generated constructor stub
    }

    public String getFormatted_address() {
        // TODO Auto-generated method stub
        return null;
    }

}

但我猜它不正确。请帮我解决这个问题：使用新的googleapis而不是旧的。我非常感谢任何帮助。谢谢你。
