我正在开发一款Android应用。在我的应用中,我使用AppCompactActivity
使用操作栏。我成功地在操作栏中实现了搜索框。但我有一个小问题。我想更改搜索框中的提示文本。请查看以下屏幕截图:
这是我的带有搜索项
的menu.xml<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="@+id/office_action_search"
android:orderInCategory="97"
android:title="Search"
android:icon="@android:drawable/ic_menu_search"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.SearchView" />
</menu>
这是我为操作栏设置带搜索功能的菜单的方法:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.office_main_menu, menu);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView search = (SearchView) menu.findItem(R.id.office_action_search).getActionView();
search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));
search.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
//tabLayout.getTabAt(0).select();
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
return false;
}
});
}
return true;
}
如何更改搜索框的提示文字?

您可以使用方法SearchView
自定义setQueryHint
的提示。
像这样修改你的代码:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.office_main_menu, menu);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView search = (SearchView) menu.findItem(R.id.office_action_search).getActionView();
search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));
search.setQueryHint("Your custom hint");
search.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
//tabLayout.getTabAt(0).select();
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
return false;
}
});
}
return true;
}

请添加以下内容
<style name="SearchViewMy" parent="Widget.AppCompat.Light.SearchView">
<item name="searchHintIcon">@null</item>
</style>

我做了一点点不同。在我的情况下,我以这种方式使用 SearchView.SearchAutoComplete 的 setText 方法:
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.menu_search, menu);
final SearchManager searchManager = (SearchManager) getContext().getSystemService(Context.SEARCH_SERVICE);
final MenuItem searchItem = menu.findItem(R.id.action_search);
final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
SearchView.SearchAutoComplete searchAutoComplete = (SearchView.SearchAutoComplete) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
searchAutoComplete.setText("Type your music...");
// rest of code
.....
}
