Android 从自动完成文本视图中选择联系人

我想使用自动完成文本视图选择联系人以发送短信。我几乎实现了我想要的，但正如你在图中所看到的一分钟内的问题。我怎样才能解决这个问题

您当前的输出似乎是HashMap.toString方法的标准输出。因此，您应该自己实现HashMap并重写toString方法。

为AutoCompleteTextView添加onItemClickListener，而不是将其作为单独的函数

 mTxtPhoneNo.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> av, View arg1, int index,
                long arg3) {
            Map<String, String> map = (Map<String, String>) av.getItemAtPosition(index);

            String name  = map.get("Name");
            String number = map.get("Phone");
            mTxtPhoneNo.setText(""+name+"<"+number+">");

        }



    });

对于AutoCompleteTextView，它可以像@user936414所说的那样很有用，但如果你有最大的应用程序，它会带来问题，对于MultiAutoCompleteTextView，更是如此，因此建议通过创建一个“自定义”哈希映射来覆盖toString方法：

public class ContactMap extends HashMap<String, String> {

/*
 * (non-Javadoc)
 * 
 * @see java.util.AbstractMap#toString()
 */
@Override
public String toString() {
    if (isEmpty()) {
        return "{}";
    }

    StringBuilder buffer = new StringBuilder(size() * 28);
    Iterator<Map.Entry<String, String>> it = entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry<String, String> entry = it.next();
        Object key = entry.getKey();

        if (key == "Name") {
            Object value = entry.getValue();
            buffer.append(value);
        } else {
            if (key == "Phone")
                buffer.append("<");
            Object value = entry.getValue();
            if (value != this) {
                buffer.append(value);
            } else {
                buffer.append("(this Map)");
            }
            if (key == "Phone")
                buffer.append(">");

        }
    }

    return buffer.toString();
}

}

这就是我在这里所做的，看看这个

public-void-onItemClick（AdapterView-av，View-v，int-index，long-arg）{Map-Map=（Map）av.getItemAtPosition（index）；迭代器myVeryOwnIterator=Map.keySet（）.Iterator（）；而（myVeryOwnIterator.hasNext（））{字符串键=（String）myVeryOwnIterator.next（）；字符串值=（String）map.get（key）；mTxtPhoneNo.setText（value）；}}

Yes，这有助于在下拉列表中显示项目。但当您点击某个条目时，文本编辑中的文本似乎是通过简单地使用item.toString.define您的哈希映射来填充的：

class ContactMap扩展哈希映射{@override public String toString（）{return+；}}}

然后在PopulatePeopleList中：

NamePhoneType=new ContactMap（）并最终删除你的onItemClick它应该是多余的。嗨，我正在尝试做一些类似于OP的事情，但有一个代码我不确定。在他的R.layout和R.menu中带有auto.xml的活动\u contact\u是否相同？谢谢@Regnarg No这两个文件不能相同。如果您只想测试自动完成文本视图，您可以在CreateOptions菜单方法上发表评论谢谢您的回复！因此，OnCreateOptions菜单与自动完成文本视图无关？您能将其修改为与
MultiAutoCompleteTextView
一起使用吗？顺便说一句，
startManagingCursor（）
已被弃用。顺便说一句，
