从自动完成文本视图中选择联系人

Question

我想使用自动完成文本视图选择联系人以发送短信。我几乎已经实现了我想要的，但是你可以在图像中看到一分钟的问题。我该如何解决？

activity_contact_with_auto.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<AutoCompleteTextView
    android:id="@+id/mmWhoNo"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="To...." >
</AutoCompleteTextView>

</LinearLayout>

custcontview.xml

Answer 1

为 AutoCompleteTextView 添加一个 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+">");

        }



    });

或为您的活动实施 OnItemClickListener 并设置

mTxtPhoneNo.setOnItemClickListener(this);

Answer 2

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

Answer 3

使用 AutoCompeleteTextView 它可以像 @user936414 所说的那样有用，但如果你有最大的应用程序，它可能会产生问题，更重要的是使用 multiAutoCompeleteTextView，因此建议通过创建“自定义”HashMap 来覆盖 toString 方法像这样：

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();
}

}

并像这样使用它

                    // Using our custom HashMap
                    ContactMap NamePhoneType = new ContactMap();
