  searchImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            search.setVisibility(View.VISIBLE);
            search.setIconifiedByDefault(false); // here i am disabling default icon
            searchImage.setVisibility(View.GONE);

        }
    });

 //This function not works as close icon not visible.
     search.setOnCloseListener(new OnCloseListener() {

        @Override
        public boolean onClose() {
            searchImage.setVisibility(View.VISIBLE);
            return false;
        }
    });

回答1:

Use the attribute app:closeIcon="@drawable/ic_my_close_icon" in your SearchView or android.support.v7.widget.SearchView

Use xmlns:app="http://schemas.android.com/apk/res-auto"

回答2:

Try this

  searchView.setOnCloseListener(new OnCloseListener() {

        @Override
        public boolean onClose() {
            searchView.clearFocus();
            return false;
        }
    });

the back option will display when you use[Complete concept about SearchView]

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="blackmonk.mobile.activity.SearchActivity" >

<item
    android:id="@+id/action_searchh"
    android:actionViewClass="android.support.v7.widget.SearchView"
    android:icon="@drawable/ic_search"
    android:showAsAction="ifRoom|collapseActionView"
    android:title="@string/search"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="always"/>

</menu>

and use

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.search_menu, menu);
    MenuItem searchItem = menu.findItem(R.id.action_searchh);
    mSearchView = (SearchView) searchItem.getActionView();
    // Associate searchable configuration with the SearchView
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.action_searchh)
            .getActionView();
    searchView.setSearchableInfo(searchManager
            .getSearchableInfo(getComponentName()));
    searchView.setQueryHint("Search here");
    //to expand search bar
    searchItem.expandActionView();
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.action_search:

        break;
    case android.R.id.home:
        onBackPressed();
        return true;
    default:
        break;
    }
    return super.onOptionsItemSelected(item);
}

If you want to get Query String use this:

Intent intent = getIntent();
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String searchQuery = intent.getStringExtra(SearchManager.QUERY);
}

Dont forget to add this code in your Manifest Activity

  <activity
        android:name="blackmonk.mobile.activity.SearchActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" >
                <action android:name="android.intent.action.MAIN" />

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

        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/search" />
    </activity>

回答4:

int search_close_btnId = android.support.v7.appcompat.R.id.search_close_btn;
ImageView search_close_btn = (ImageView) searchView.findViewById(search_close_btnId);
search_close_btn.setImageResource(R.drawable.ic_close_search);

回答5:

int searchCloseIconButtonId = SearchView.getContext().getResources()
            .getIdentifier("android:id/search_close_btn", null, null);
    ImageView closeButton = (ImageView) this.mSearchView.findViewById(searchCloseIconButtonId);
    closeButton.setImageResource(R.mipmap.close); //any icon image

If you want you can add click listener on closeButton
