Question

当我点击自动完成列表视图时，我想更新Sq-lite db表中的特定行值。这是我的db帮助程序代码。

 public boolean updateFilterUser(String strUserName)
  {
      SQLiteDatabase db = getWritableDatabase();
      ContentValues values = new ContentValues();
      values.put(COL_AllPost_ActivityStatus, "1");
      values.put(COL_AllPost_inspectorname, strUserName);
      int i = db.update(Table_AllPost_Table, values, COL_AllPost_inspectorname + "= ? ", new String[]{strUserName});

      return i > 0;
  }

这是活动代码

  userAutoComplete_TextView = (AutoCompleteTextView) findViewById(R.id.autoComplete_UserList);
        userAutoComplete_TextView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, userlist));
        userAutoComplete_TextView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

                String foundItem = arg0.getItemAtPosition(arg2).toString();
                boolean inputQuery = dbhelper.updateFilterUser(foundItem);
                Log.e("Post ", " Edited Succesfully !!!" + inputQuery);

                Filter filter = new Filter();
                filter.setName(foundItem);
                filter_ArrayList.add(filter);
                filterAdapter = new FilterAdapter(Filter_Screen.this, R.layout.filter_list_item, filter_ArrayList);
                listView_Filter.setAdapter(filterAdapter);

                Log.e("Updated ListView --->", "" + foundItem);

            }
        });

我的行没有更新。

请使用谎言，希望这对您有所帮助。

public boolean updateFilterUser(String strUserName){

  SQLiteDatabase db = getWritableDatabase();
  ContentValues values = new ContentValues();
  values.put(COL_AllPost_ActivityStatus, "1");

  String selection = COL_AllPost_inspectorname + " LIKE ?";
  String[] selectionArgs = {strUserName};
  int i = db.update(Table_AllPost_Table, values, selection, selectionArgs);

  return true;
}

更新查询在Android中返回false
