更改 searchView 的光标颜色

Question

我知道这个问题已经发布了数百万次，但我无法为我的案例找到有效的解决方案。

我需要更改 searchView 的光标颜色。我没有 searchView 的 xml 定义，我以编程方式使用它。

这是我的代码：

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_contacts, menu);

    SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView search = (SearchView) menu.findItem(R.id.action_search).getActionView();
    search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

    return true;
}

我正在使用这个：import android.support.v7.widget.SearchView;

谢谢

你尝试了吗？

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_contacts, menu);

    SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView search = (SearchView) menu.findItem(R.id.action_search).getActionView();
    search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

    AutoCompleteTextView searchTextView = (AutoCompleteTextView) search.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    try {
        Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
        mCursorDrawableRes.setAccessible(true);
        mCursorDrawableRes.set(searchTextView, R.drawable.cursor); //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);
}

drawable/cursor.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <solid android:color="#ffffff" />
    <size android:width="2dp" />
</shape>

例如：Changing the cursor color in SearchView without ActionBarSherlock

仅在 onCreate() 方法中添加此代码对我有效

        searchView = (SearchView)findViewById(R.id.search_view);
        SearchView.SearchAutoComplete searchAutoComplete =
                (SearchView.SearchAutoComplete)searchView.findViewById(androidx.appcompat.R.id.search_src_text);
        AutoCompleteTextView searchTextView = (AutoCompleteTextView) searchView.findViewById(androidx.appcompat.R.id.search_src_text);
        try {
            Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
            mCursorDrawableRes.setAccessible(true);
            mCursorDrawableRes.set(searchTextView, 0);
        } catch (Exception e) {
        }

另一种改变光标颜色的方法可以通过样式来完成。

拳头创建cursor.xml可绘制文件

 <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#ffffff" />   //your desired cursor color
<size android:width="2dp" />
</shape>

在style/themeres文件夹中定义样式

<style name="cursorColor" parent="Widget.AppCompat.AutoCompleteTextView">
<item name="android:textCursorDrawable">@drawable/cursor</item>

并在您的相关 Activity 样式或 AppTheme

中添加以下行

 <item name="autoCompleteTextViewStyle">@style/cursorColor</item>
