我遇到搜索视图问题。我想在我的应用程序中使用搜索视图。在我的应用程序中，我正在添加用户详细信息，我想使用搜索视图搜索用户详细信息。
我在这里发布代码请帮帮我。
我要求
的活动 @Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.button_search:
Log.i("sample", "cliked");
onSearchRequested();
break;
和serchview活动如下图所示我在下面的代码中使用了sqlite。 问题是它没有调用searchviewactivity。
private ListView mListView;
private SearchView searchView;
private CustomersDbAdapter mDbHelper;
Cursor cursor;
private TextView inspectionDate;
private TextView customerText;
private TextView nameText;
private TextView addressText;
private TextView cityText;
private TextView stateText;
private TextView zipCodeText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
searchView = (SearchView) findViewById(R.id.search);
searchView.setIconifiedByDefault(false);
searchView.setOnQueryTextListener(this);
searchView.setOnCloseListener(this);
mListView = (ListView) findViewById(R.id.list);
inspectionDate = (TextView) findViewById(R.id.inspectionDate);
displayDate();
mDbHelper = new CustomersDbAdapter(this);
try {
mDbHelper.open();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//Clean all Customers
mDbHelper.deleteAllCustomers();
//Add some Customer data as a sample
mDbHelper.createCustomer("PIZZA1", "Pizza Hut", "1107 West Adams Boulevard", "", "Los Angeles", "CA", "90007");
mDbHelper.createCustomer("PIZZA2", "Pizza Hut", "1562 West Pico Boulevard", "", "Los Angeles", "CA", "90015");
mDbHelper.createCustomer("PIZZA3", "Pizza Hut", "718 South Los Angeles Street", "", "Los Angeles", "CA", "90014");

}
@Override

// Specify the columns we want to display in the result
String[] from = new String[] {

private void displayDate() {

inspectionDate.setText(

这里我发布了客户详细信息活动中的清单详细信息。我需要调用搜索视图。我在呼唤它，但它没有用。我很震惊的代码请帮帮我。

答案 0 :(得分：0)
这应该是您的查询，以检索与该字符串匹配的所有数据
public boolean onQueryTextChange(String newText) {
String query ="SELECT * FROM "+TABLENAME+" WHERE "+KEYNAME+" like '%"+newText+"%'"
showResults(query);
return false;
}
