问题在我的活动

Question

你好我所有的搜索活动进入我的应用程序，如果我尝试通过提示文本关键字来搜索一个项目，但如果我尝试搜索也包含一些应用程序崩溃的项目，例如，如果我尝试搜索文本“家庭”搜索很好，但如果我搜索“家3”应用程序崩溃。错误是：异常非法字符功能于查询在索引我想的是，搜索的工作也不错键入文字或文字+数字EXC .. 谢谢

重要： 搜索活动调用一个URL编码，“ADSEARCH_URL”

public static final String ADSEARCH_URL="https://gjeme.com/apps/menjehere/index.php?action=searchAd&categoryId=%s&adcity=%s&q=%s"; 

这是搜索活动：

public class SearchActivity extends AppCompatActivity {

    toolbar = (Toolbar) findViewById(R.id.toolbar); 
    if (toolbar != null) { 
    toolbar.setTitle("Browse Ads"); 
    setSupportActionBar(toolbar); 
    getSupportActionBar().setHomeButtonEnabled(true); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    } 
    getActionBarTextView(); 

    typeface = Typeface.createFromAsset(getAssets(), "fonts/GandhiSerif- Bold.otf"); 
    TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);

    catAddList = new ArrayList<CatAdd>(); 

    categoryId = getIntent().getExtras().getString("categoryId", "0"); 
    keyword = getIntent().getExtras().getString("keyword","keyword"); 
    city  = getIntent().getExtras().getString("city","city"); 

    new SearchList().execute(); 

    lsv.setOnItemClickListener(new OnItemClickListener()

我觉得这是不是这里的字母数字字符的任何问题，但SPACE被创建一个，而您将文本添加到URL。
用%20替换搜索关键字space(es)，希望你会发现它很好。
