为了控制您在自动完成视图中显示项目的方式，您必须在适配器中设置 textViewResourceId。您可以使用 ArrayAdapter 并android.R.layout.simple_dropdown_item_1line作为 textViewResourceId 提供，如下所示。
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, yourList);
AutoCompleteTextView autocompleteView = (AutoCompleteTextView) findViewById(R.id.autocomplete_box);
autocompleteView.setAdapter(adapter);
或者
如果您想为显示的项目创建自己的样式，请创建一个TextView像这样作为根元素的 XML（让我们my_custom_dropdown.xml用黑色文本和白色背景命名）
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:padding="5sp"
android:textColor="@color/black"
android:background="@color/white"/>
然后参考适配器中的 xml，如下所示 -
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.my_custom_dropdown, yourList);

只是要指出，使用android.R.layout.simple_dropdown_item_1line它会给你上面遇到的同样的问题。所以你最好TextView在一个.xml文件中创建你自己的。

如果将代码从 更改"android.R.layout.simple_list_item_1"为 对您"android.R.layout.simple_dropdown_item_1line" 不起作用，
您应该尝试在setContentView之前编写此代码
setTheme(android.R.style.Theme);
它对我有用:)

只需使用"android.R.layout.simple_list_item_1"而不是"android.R.layout.simple_dropdown_item_1line".....您的问题将得到解决... :)

我创建了一个示例项目：AutoCompleteTextViewAdapter(Github Repo)
您需要实现以下源代码行：
活动
ArrayAdapter<String> myCustomAdapter = new ArrayAdapter<String>(this, R.layout.text_custom_view, countriesNames);
final AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.auto_complete_text_view);
textView.setAdapter(myCustomAdapter);
带有自定义 TextView 的 XML
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/country_name"
style="@style/CustomTextView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true" />
最后结果

public class SelectState extends Activity {
final static int[] to = new int[] { android.R.id.text1 };
final static String[] from = new String[] { "state" };
private TextView mStateCapitalView;
private AutoCompleteTextView mStateNameView;
private AutoCompleteDbAdapter mDbHelper;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDbHelper = new AutoCompleteDbAdapter(this);
setContentView(R.layout.selectstate);
Button confirmButton = (Button) findViewById(R.id.confirm);
confirmButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
setResult(RESULT_OK);
finish();
}
});
mStateCapitalView = (TextView) findViewById(R.id.state_capital);
mStateNameView = (AutoCompleteTextView) findViewById(R.id.state_name);
// Create a SimpleCursorAdapter for the State Name field.
SimpleCursorAdapter adapter =
new SimpleCursorAdapter(this,
android.R.layout.simple_dropdown_item_1line, null,
from, to);
mStateNameView.setAdapter(adapter);
// Set an OnItemClickListener, to update dependent fields when
// a choice is made in the AutoCompleteTextView.
mStateNameView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> listView, View view,
int position, long id) {
// Get the cursor, positioned to the corresponding row in the
// result set
Cursor cursor = (Cursor) listView.getItemAtPosition(position);
// Get the state's capital from this row in the database.
String capital =
cursor.getString(cursor.getColumnIndexOrThrow("capital"));
// Update the parent class's TextView
mStateCapitalView.setText(capital);
}
});
// Set the CursorToStringConverter, to provide the labels for the
// choices to be displayed in the AutoCompleteTextView.
adapter.setCursorToStringConverter(new CursorToStringConverter() {
public String convertToString(android.database.Cursor cursor) {
// Get the label for this row out of the "state" column
final int columnIndex = cursor.getColumnIndexOrThrow("state");
final String str = cursor.getString(columnIndex);
return str;
}
});
// Set the FilterQueryProvider, to run queries for choices
// that match the specified input.
adapter.setFilterQueryProvider(new FilterQueryProvider() {
public Cursor runQuery(CharSequence constraint) {
// Search for states whose names begin with the specified letters.
Cursor cursor = mDbHelper.getMatchingStates(
(constraint != null ? constraint.toString() : null));
return cursor;
}
});
}
}
请检查 line final static int[] to = new int[] { android.R.id.text1 };

这是最简单的方法。创建您自己的 TextView xml 文件。例如 custom_textview.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tv"
android:textColor="@color/font_content"
android:padding="5sp"
android:textSize="16sp"
android:layout_width="match_parent"
android:background="@drawable/any_background"
android:singleLine="true"
android:gravity="center"
android:layout_height="match_parent"/>
然后在你的活动中
//Create adapter object
ArrayAdapter<String> adpt = new ArrayAdapter<String>(context,R.layout.mytextview, what_ever_array_object_here);
searchAutoComplete.setAdapter(adpt);
