Question

我做了一个搜索小部件，工作正常。但是当我按下后退按钮时，onCancel和onDismiss永远不会调用。

在PCRListActivity.java中：

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.list, menu);
    // Get the SearchView and set the searchable configuration
    SearchManager searchManager = (SearchManager) this.getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
    // Assumes current activity is the searchable activity
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default
    searchManager.setOnCancelListener(new SearchManager.OnCancelListener() {
        @Override
        public void onCancel() {
            getLoaderManager().restartLoader(LOADER_ID_PRODUCTS, null, PCRListActivity.this);
        }
    });
    searchManager.setOnDismissListener(new SearchManager.OnDismissListener() {
        @Override
        public void onDismiss() {
            getLoaderManager().restartLoader(LOADER_ID_PRODUCTS, null, PCRListActivity.this);
        }
    });
    return true;
}

那么，我做错了什么？

我也遇到了这个问题，我别无选择，只能放弃“oncloselistener”。相反，您可以获取menuItem，然后是setOnActionExpandListener。然后覆盖unimplents方法。我想close和dissmiss方法只适用于Progress Dialogs。

@Override
public boolean onMenuItemActionExpand(MenuItem item) {
// TODO Auto-generated method stub

return true;
}

@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
//do what you want to when close the sesarchview
//remember to return true;

return true;
}

在搜索小部件上退回或取消不起作用
