アクティビティ検索のクラッシュ

Question

こんにちは、私は検索活動に問題があります。私が例えばiphone 6のようなアイテムを検索し、 "iphone"か "6"か "i"と他のexcだけを入力しようとすると...検索は神を働かせますが、アイテムの全体の名前をこの場合：iPhone 6、アプリがクラッシュします。 これはコードです：

public class SearchActivity extends AppCompatActivity { 

Toolbar toolbar; 
ListView lsv; 
String categoryId,keyword,city; 
ProgressDialog progressBar; 
List<CatAdd> catAddList; 
CateAdDisplayAdapter adapter; 
Typeface typeface; 

@SuppressLint("NewApi") @Override 
protected void onCreate(@Nullable Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activty_search); 
    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); 
    ViewPager viewPager = (ViewPager) findViewById(R.id.pager); 

    lsv = (ListView)findViewById(R.id.listView1); 
    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() 
    { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
           long arg3) { 
      Intent intent = new Intent(getApplicationContext(), BrowseAdsDetailActivity.class); 
      intent.putExtra("adId", String.valueOf(catAddList.get(arg2).getAddid())); 
      startActivity(intent); 
     } 
    }); 
} 
@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 

    if(id==android.R.id.home) 
    { 
     onBackPressed(); 
    } 
    return super.onOptionsItemSelected(item); 
} 

@Override 
public void onBackPressed() { 
    // TODO Auto-generated method stub 
    super.onBackPressed(); 

} 
private TextView getActionBarTextView() { 
    TextView titleTextView = null; 

    try { 
     Field f = toolbar.getClass().getDeclaredField("mTitleTextView"); 
     f.setAccessible(true); 
     titleTextView = (TextView)f.get(toolbar); 
     titleTextView.setTypeface(typeface); 

    } catch (NoSuchFieldException e) { 
    } catch (IllegalAccessException e) { 
    } 
    return titleTextView; 
} 

class SearchList extends AsyncTask<Void, Void, Void>

    String jsonStr = null; 
    CustomProgressDialog cd = new CustomProgressDialog(); 
    @Override

     } else { 
      Log.e("ServiceHandler", "Couldn't get any data from the url"); 
     } 
     return null;

    @Override 
    protected void onPostExecute(Void result) { 
     super.onPostExecute(result); 
     cd.dismissdialog();

     lsv.setAdapter(adapter); 
    } 
}

あなたはAPI呼び出しを行っていると仮定：

あなたのURLにパラメータをエンコードする必要があります。

String query = URLEncoder.encode("phone 6", "utf-8"); 
String url = "http://myurl.com/search?q=" + query; 

結果は次のようになります。http://myurl.com/search?q=phone%206
