android - 最后如何去掉 Spinner 的 ellipsize 或 '...'？

Question

我做了几个 Spinner，Spinner 的长度(宽度)比某些项目的名称短。

例如，选择一个项目之后。

[南韩...▼]

但我想要的是:

[韩国▼]

(但不是[South Kore▼a]也不是重叠的。)

Layout(XML) 中的 Spinner 似乎没有像 ellipsize 这样的任何属性。而且我在网上找不到任何信息。

有什么办法可以解决这个问题吗？

3。 Java

    ArrayAdapter<String> categoryAdapter = new ArrayAdapter<>(getContext(), android.R.layout.simple_spinner_item, getResources().getStringArray(R.array.categories_array));
    ArrayAdapter<String> countryAdapter = new ArrayAdapter<>(getContext(), android.R.layout.simple_spinner_item, getResources().getStringArray(R.array.countries_array));

    categorySP.setOnItemSelectedListener(this);
    countrySP.setOnItemSelectedListener(this);

    categoryAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    countryAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    categorySP.setAdapter(categoryAdapter);
    countrySP.setAdapter(countryAdapter);

Answer 1

为 Spinner 提供自定义布局:

ArrayAdapter adapter= new ArrayAdapter(mOwnerActivity, R.layout.simple_list_item_1, new ArrayList<>()); 

布局:R.layout.simple_list_item_1 -->

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dp"
    android:layout_marginBottom="10dp" />

将适配器设置为您的微调器:

spinner.setAdapter(adapter);
