SearchView query hint before clicking it

问题

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" />

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

回答1:

You can add these below lines:

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

and add this to hiding focus (Keyboard)

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

Use this XML:

android:queryHint="hint"
app:queryHint="hint"
app:defaultQueryHint="hint"
android:iconifiedByDefault="false"  // this line
app:iconifiedByDefault="false"

app used for {android.support.v7.widget.SearchView}

回答3:

You can just add android:iconifiedByDefault="false" it just displays the query hint string by default

回答4:

make setIconified(false)-that works for me that works,but when it is unclicked,again hint disappears

回答5:

This worked for me:

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

Also, don't forget to add these to manifest.xml:

<intent-filter>
    <action android:name="android.intent.action.SEARCH"/>
    <action android:name="android.intent.action.MAIN" />

    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

In xml, You can use this android:queryHint="Search"
