If you want to change the look of the dropdown items change the XML layout you pass to the ArrayAdapter, (in your case this is android.R.layout.simple_dropdown_item_1line).
如果您想更改下拉项的外观，请更改您传递给 ArrayAdapter 的 XML 布局（在您的情况下为android.R.layout.simple_dropdown_item_1line）。
Lets make a new layout named my_list_item.xmlin res/layout:
让我们创建一个名为my_list_item.xmlin的新布局res/layout：
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="?android:attr/dropDownItemStyle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="5dp"
android:textAppearance="?android:attr/textAppearanceMediumInverse"
android:textColor="#00f" />
This text is smaller, blue, and centered. I don't recommend using this layout, it's more to demonstrate that you can customize it.
此文本更小、蓝色且居中。我不推荐使用这种布局，更多的是证明你可以自定义它。
Now use this instead:
现在改用这个：
view = (AutoCompleteTextView)findViewById(R.id.text);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.my_list_item, data);
view.setAdapter(adapter);
When you set attributes here (like the text color):
当您在此处设置属性时（如文本颜色）：
<AutoCompleteTextView
android:id="@+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Tapez votre 1texte"
android:textColor="#000"
/>
You are only changing the box above the dropdown list (the box that you see before you interact with the AutoCompleteTextView). Hope that helps!
您只是更改下拉列表上方的框（您在与 AutoCompleteTextView 交互之前看到的框）。希望有帮助！

This question might be old but I believe this is very important for me to share. I had been experiencing the same problem as OP but it is because I was using 'getApplicationContext()' in place of 'this'
这个问题可能很老，但我相信这对我来说非常重要。我遇到了与 OP 相同的问题，但这是因为我使用的是“getApplicationContext()”而不是“this”
Wrong
错误的
ArrayAdapter<String> adapter = new ArrayAdapter<String>
(getApplicationContext(), android.R.layout.simple_list_item_1, PLACES);
Correct
正确的
ArrayAdapter<String> adapter = new ArrayAdapter<String>
(this, android.R.layout.simple_list_item_1, PLACES);

I tried setting up the theme before setcontext, tried different resources parameter in arrayAdapter and tried different theme ,but nothing helped.
我尝试在 setcontext 之前设置主题，在 arrayAdapter 中尝试了不同的资源参数并尝试了不同的主题，但没有任何帮助。
Then I changed the context from 'this' to 'getApplicationContext' but the problem was persistent.
然后我将上下文从“this”更改为“getApplicationContext”，但问题仍然存在。
Finally I changed the context parameter to "getBaseContext()" and the problem was solved.
最后我将上下文参数更改为“getBaseContext()”，问题就解决了。

i got my solution in slecting layout of "select_dialog_singlechoiceArrayAdapter<String > s1= new ArrayAdapter<String>
(this,android.R.layout.select_dialog_singlechoice,state);enter image description here
我在“select_dialog_singlechoice enter image description here”的选择布局中得到了我的解决方案ArrayAdapter<String > s1= new ArrayAdapter<String>
(this,android.R.layout.select_dialog_singlechoice,state);
instead of get application context write "this" in ArrayAdapter<>;
在 ArrayAdapter<> 中写入“this”而不是获取应用程序上下文；
try using different layouts u will definately solve your queries
尝试使用不同的布局你肯定会解决你的查询

I solved this issue by doing a simple tricky Way,
我通过一个简单的棘手方式解决了这个问题，
Just change the Theme of your activity declared in your AndroidManifest.xml as,
只需将您在 AndroidManifest.xml 中声明的活动主题更改为，
<activity
android:name=".YourActivity"
android:configChanges="keyboardHidden|orientation|screenSize"
android:theme="@style/Theme.AppCompat.Light.NoActionBar"
android:windowSoftInputMode="stateHidden"></activity>
and in the Activity as follows,
并在如下活动中，
ArrayAdapter<String> adapter = new ArrayAdapter<String>
(getActivity(), android.R.layout.select_dialog_item, arraylist);
回答by Kanth
A tricky solution for this is:
Add this line
setTheme(android.R.style.Theme);before setContentView()in your activity file in which your autocompletetextview is present. Let me know if this works.
一个棘手的解决方案是：添加这一行
setTheme(android.R.style.Theme); setContentView()在您的自动完成文本视图所在的活动文件中之前。让我知道这个是否奏效。

didldum 的回答https://code.google.com/p/android/issues/detail?id=5237
workaround by extending the theme and overriding the 2 styles for the typed text and the suggest text:
通过扩展主题并覆盖键入文本和建议文本的 2 种样式来解决方法：
use an extended theme in your manifest: ... ...
create the new theme (res/values/themes.xml) which uses fixed styles: ... @style/AutoCompleteTextViewLight @style/Widget.DropDownItemLight ...
create the styles (res/values/styles.xml) which fix the color: ... @android:color/primary_text_light @android:color/primary_text_light
在清单中使用扩展主题： ... ...
创建使用固定样式的新主题 (res/values/themes.xml)： ... @style/AutoCompleteTextViewLight @style/Widget.DropDownItemLight ...
创建固定颜色的样式（res/values/styles.xml）： ... @android:color/primary_text_light @android:color/primary_text_light
