我为翻译程序创建了一个包含 LinearLayout 的简单 Scrollview 。使用按钮，用户应该能够查看给定单词的一系列翻译 - 这一切都按照我的希望工作（可能不是最有效的编码，但是嘿？）但是当使用一系列填充LinearLayout时添加视图我无法让它们显示在屏幕上 - 我进行了一些研究并经历了无效，postinvalidate，updateviewlayout和refreshdrawablestate的各种尝试，而没有在布局中出现任何新视图。我唯一的成功来自于setcontentview。
问题是 setcontentview基本上重绘了所有布局，因此擦除了我正在使用的autocompletetextview的所有按钮侦听器和下拉适配器。我的程序变成了一个带有可滚动翻译单词列表的shell 。
我想要做的是将addview合并，然后变得可见，而不会丢失应用程序的其他程序设计工作。它基本上应该保持功能，但我却失去了如何做到这一点。我上面尝试过的所有解决方案都没有显示添加视图。
我的OnClickListener代码，瑕疵和所有：
private OnClickListener TranslatorListener = new OnClickListener()
{
@Override
public void onClick(View v)

int wordpos;
View view = getLayoutInflater().inflate(R.layout.activity_scubatranslator, null, false);

sb.setBackgroundColor(getResources().getColor(R.color.black_transparent_70));
LinearLayout scroll_list = (LinearLayout) view.findViewById(R.id.Scroller);
scroll_list.removeAllViews();
if (current_word == ""){
AutoCompleteTextView source = (AutoCompleteTextView) findViewById(R.id.Translator_Search_Box);
current_word = source.getText().toString();
}

wordpos = Arrays.asList(current_list).indexOf(current_word);

尝试使用类似的内容初始化TextView：
TextView text = (TextView) getLayoutInflater().inflate(
R.layout.include_textview, container, false);
container是您要填充的LinearLayout。
