单击之前的SearchView查询提示 [英] SearchView query hint before clicking it

问题描述

我有一个搜索视图，并且有一个查询提示属性.但是，只有在单击搜索视图后，提示才会出现.有没有办法让它在被点击之前出现?

I have a search view and I have a query hint attribute. However the hint appears only after clicking on the search view. Is there a way to make it appear before it has been clicked?

<SearchView
        android:id="@+id/searchView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentEnd="true"
        android:layout_alignParentStart="true"
        android:layout_below="@+id/textView4"
        android:layout_marginBottom="14dp"
        android:layout_marginTop="30dp"
        android:queryHint="Search" />

我看到了另一个带有类似查询的SO问题，但是并没有解决.这就是为什么我再次询问.

I have seen another SO question with a similar query, but it wasn't solved. That's why I am asking again.

推荐答案

您可以在下面的行中添加以下内容:

You can add these below lines:

SearchView searchView = (SearchView) findViewById(R.id.searchView);
searchView.onActionViewExpanded();
searchView.setIconified(true);

并将其添加到隐藏焦点(键盘)

and add this to hiding focus (Keyboard)

 new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                search.clearFocus();
            }
    }, 300);
