推荐答案

您需要为此创建自定义适配器类，然后才能将textview设置为此.

you need to create custom adapter class for this, then you can set textview to this like.

autoAdapter = new AutoAdapter(this, R.layout.autocompletelistview_test1,
            edittext);

这是autocompletelistview_test1

Here is autocompletelistview_test1

<?xml version="1.0" encoding="utf-8"?>
<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="44dip"
android:gravity="center_vertical"

android:singleLine="true"
android:ellipsize="end"
android:layout_marginRight="12dip"
android:textStyle="bold"
android:textColor="#cc3333"
android:id="@+id/textview"
android:textSize="14sp" />

使用以下代码来更改下拉菜单的背景颜色，例如

use following code to change background color of dropdown like

 autocomplete.setDropDownBackgroundResource(R.color.autocompletet_background_color);

，您可以在string.xml中设置这样的值

and you can set value like this in string.xml

   <color name="autocompletet_background_color">#EFEFEF</color>

如果要更改下拉菜单项的文本颜色，请执行以下操作.

If you want to change text color of dropdown item then do like following.

.

 @Override
public View getView(int position, View v, ViewGroup parent)
{
    View mView = v ;
    if(mView == null){
        LayoutInflater vi = (LayoutInflater)appContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mView = vi.inflate(id, null);
    }
    TextView text = (TextView) mView.findViewById(R.id.textview);
    if(getItem(position) != null )
    {
        text.setTypeface(faceBold);
        if(getItem(position).equals("check some condition if you want. "))
        {
            text.setTextColor(Color.parseColor("#999999"));
            text.setText("set some text");
        }
        else
        {
            text.setTextColor(Color.parseColor("#cc3333"));
                text.setText(getItem(position));
        }
    }
    return mView;
}
