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

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

<TextView
    android:id="@+id/ccontName"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Large Text"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:textColor="#A5000000" />

<TextView
    android:id="@+id/ccontNo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_below="@id/ccontName"
    android:text="Medium Text"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:textColor="#A5000000" />

<TextView
    android:id="@+id/ccontType"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@id/ccontNo"
    android:layout_alignParentRight="true"
    android:layout_marginRight="14dp"
    android:text="Small Text"
    android:textAppearance="?android:attr/textAppearanceSmall"
    android:textColor="#A5000000" />
 </LinearLayout>

代码

public class ContactWithAuto extends Activity {

private ArrayList<Map<String, String>> mPeopleList;
private SimpleAdapter mAdapter;
private AutoCompleteTextView mTxtPhoneNo;

@Override

    super.onCreate(savedInstanceState);

    mTxtPhoneNo = (AutoCompleteTextView) findViewById(R.id.mmWhoNo);
    mAdapter = new SimpleAdapter(this, mPeopleList, R.layout.custcontview,
            new String[] { "Name", "Phone", "Type" }, new int[] {
                    R.id.ccontName, R.id.ccontNo, R.id.ccontType });
    mTxtPhoneNo.setAdapter(mAdapter);

            while (phones.moveToNext()){
                //store numbers and display a dialog letting the user select which.
                String phoneNumber = phones.getString(

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+">");

        }



    });

或为您的活动实施 OnItemClickListener 并设置

mTxtPhoneNo.setOnItemClickListener(this);

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 并覆盖 toString 方法。

使用 AutoCompeleteTextView 就像@user936414 所说的那样，它可能很有用，但如果你有最大的应用程序，它可能会产生问题，甚至更多的是使用 multiAutoCompeleteTextView 所以建议通过创建一个“自定义”HashMap 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();
}

}

并像这样使用它

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