改变光标颜色搜索查看无ActionBarSherlock [英] Changing the cursor color in SearchView without ActionBarSherlock

问题描述

我试图改变闪烁光标的颜色对搜索查看小部件ICS +。我已经试过如下：

I am attempting to change the color of the blinking cursor on the SearchView widget in ICS+. I have tried the following:

• 添加＆LT;项目名称=机器人：textCursorDrawable＆GT; @空＆LT; /项目＆GT; 来我 主题
• 添加为AutoCompleteTextViews一个风格，我的主题，并设置该样式的textCursorAttribute到@null
• 设置安卓textCursorDrawable =@空直接在搜索查看

• Adding <item name="android:textCursorDrawable">@null</item> to my theme
• Adding a style for AutoCompleteTextViews to my theme and setting the textCursorAttribute of that style to @null
• Setting android:textCursorDrawable="@null" directly on the SearchView

我在这里找到了答案（在搜索查看 自定义光标颜色），但有不是searchAutoCompleteTextView非ABS风格，所以无法尝试。我也找了一个Java方法来设置文本光标绘制，但无法找到一个 - 我修改Java中的搜索查看其它方面将能够与光标这样做，如果有可用的方法。

I read the answer here (Custom cursor color in SearchView), but there is not a non-ABS style for searchAutoCompleteTextView, so could not try this. I also looked for a Java method to set the text cursor drawable, but could not find one - I am modifying other aspects of the SearchView in Java and would be able to do so with the cursor if there were a method available.

我已经定制了搜索查看pretty的广泛开展，但是这最后一个变化是保持它寻找正确的 - 光标是白色在白色背景上，所以它不容易看到。的事情，我可以尝试任何其他的想法？

I have customized the SearchView pretty extensively, but this one last change is keeping it from looking right - the cursor is white on a white background, so it is not easily visible. Any other ideas of things I can try?

推荐答案

根据该意见，并回答上面我做了这到底是怎么看使用反射的例子。这解决了我的应用程序的问题。希望这样可以节省别人一些时间。

Based on the comments and answers above I made an example of how this could look using reflection. This solves the problem in my app. Hope it saves someone else some time.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.entity_list_actions, menu);
    final SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
    final int textViewID = searchView.getContext().getResources().getIdentifier("android:id/search_src_text",null, null);
    final AutoCompleteTextView searchTextView = (AutoCompleteTextView) searchView.findViewById(textViewID);
    try {
        Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
        mCursorDrawableRes.setAccessible(true);
        mCursorDrawableRes.set(searchTextView, 0); //This sets the cursor resource ID to 0 or @null which will make it visible on white background
    } catch (Exception e) {}
    return super.onCreateOptionsMenu(menu);
}

这是0也能像R.drawable.my_cursor任何其他资源ID

That 0 could be any other resource ID like R.drawable.my_cursor
