Question

在活动中，我使用 SearchView ，我想在发生任何结果时实施下拉可能吗？谢谢你。

searchActivity.java代码

protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.search_activity);

    isSearchVisible = false;
    isHomeVisible = true;

    mActivity = this;
    mContext = getApplicationContext();

    mSearchView = (SearchView) findViewById(R.id.m_searchview);
    edtFromDate = (EditText) findViewById(R.id.edt_from_date);
    edtEndDate = (EditText) findViewById(R.id.edt_end_date);
    btnSearchNow = (Button) findViewById(R.id.btn_search_now);

    int searchPlateId = mSearchView.getContext().getResources()
            .getIdentifier("android:id/search_plate", null, null);
    View searchPlateView = mSearchView.findViewById(searchPlateId);
    if (searchPlateView != null) {
        searchPlateView.setBackgroundColor(Color.WHITE);
    }

}

search_activity.xml代码

这是清单应用程序的清单代码

<activity android:name=".activity.SearchActivity"
        android:label="@string/title_search_activity"
        android:configChanges="orientation"></activity>
