如何处理左箭头点击？ 我通过意图进行了搜索，没关系：

@Override
protected void onNewIntent(Intent intent) {
    handleIntent(intent);
}

private void handleIntent(Intent intent) {
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        mFilter = intent.getStringExtra(SearchManager.QUERY);
        ...search query
    }
}

和我的关闭按钮代码：

ImageView closeButton = (ImageView) searchView.findViewById(R.id.search_close_btn);
    closeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
...
}

如何处理左箭头？

Answer 1

SearchView小部件中有OnCloseListener。

searchView.setOnCloseListener(new SearchView.OnCloseListener() {
    ...
});

Answer 2

// When using the support library, the setOnActionExpandListener() method is
// static and accepts the MenuItem object as an argument
MenuItemCompat.setOnActionExpandListener(menuItem, new OnActionExpandListener() {
@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
    // Do something when collapsed
    return true;  // Return true to collapse action view
}

@Override
public boolean onMenuItemActionExpand(MenuItem item) {
    // Do something when expanded
    return true;  // Return true to expand action view
}
});
