Question

我正在尝试在AlertDialog中添加一个AutoCompleteTextBox，但我不知道如何做到这一点。任何有关相同的帮助将不胜感激。此外，在AutoCompleteTextBox中，我想通过google Places API显示这些地方。我为此实现了google Places API，如果我为此运行网址，则显示结果但是当我在AutoCompleteText框中输入2个或更多字符时，它会显示以下错误：

以下是我实现适配器的方式：

AutoCompleteTextView autoCompView = (AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);
autoCompView.setAdapter(new PlacesAutoCompleteAdapter(this, R.layout.list_item));

和list_item中的AutoCompleteTextView如下：

<AutoCompleteTextView
        android:id="@+id/autoCompleteTextView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/BookCabtxt"
        android:ems="10"
        >
    </AutoCompleteTextView>

注意：这仅用于试用目的。实际上，我想将此AutoCompleteTextView放在AlertDialog中。所以主要是我有两个疑问：

1>creating an AutoCompleteTextView inside alertDialog
2>Generating results in that AutoCompleteTextView

如果有任何不清楚的地方，请在评论中提出问题，并提前赦免我的英语和无知的开发。

您需要使用为Dialog创建的视图。你应该有这样的东西。

LayoutInflater factory = LayoutInflater.from(MyActivity.this);
final View textEntryView = factory.inflate(R.layout.my_layout, null); 
AutoCompleteTextView textViewCountry = (AutoCompleteTextView)textEntryView.findViewById(com.example.FindItNear.R.id.autocomplete_radius);
