androidの一意のIDに基づいてビューを変更する方法

Question

私は3つのレイアウトがあります。私はユニークな識別子に基づいてアダプタビューで表示する必要があります。私はswitch case.Butを使用して3つの異なるビューを分類しました。私はコードを実行すると、1つだけのレイアウトビューを選択し、エミュレータで表示していました。ユニークなID。

public class PromotionsFeedActivity extends AppCompatActivity implements View.OnClickListener{ 


    JSONObject jsonObject=new JSONObject(); 
    public static ArrayList<String> Id=new ArrayList<String>(); 

    public static ArrayList<String> Titles = new ArrayList<String>(); 
    public static ArrayList<String> Title2 = new ArrayList<String>(); 
    public static ArrayList<String> Categorie = new ArrayList<String>(); 
    public static ArrayList<String> videoURL=new ArrayList<String>(); 
    public static ArrayList<String> Pictures=new ArrayList <String>(); 

    public static ArrayList<String> PartnerId=new ArrayList<String>(); 
    public static ArrayList<String> BuyUrl; 



    public static ArrayAdapter<String> pfAdapter; 
    ListView show; 
    VideoView videoView; 
    ImageView btnWatchVideo; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_promotions_feed); 

//  Id=new ArrayList<String>(); 
//  Titles=new ArrayList<String>(); 
//  Title2=new ArrayList<String>(); 
//  Categorie=new ArrayList<String>(); 
//  videoURL=new ArrayList<String>();

//  BuyUrl=new ArrayList<String>(); 

     btnWatchVideo = (ImageView) findViewById(R.id.btnWatchVideo); 
     btnWatchVideo.setOnClickListener(new View.OnClickListener() { 
      @Override

       startActivity(new Intent(PromotionsFeedActivity.this,MediaActivity.class));

      Log.i("PartnerSize",String.valueOf(PartnerId.size())); 
      String id = PromotionsFeedActivity.PartnerId.get(i); 

      switch(id){

Answer 1

int resourcePromotionFeedAdapter::PromotionFeedAdapterから削除してください。

はあなた Activityの onCreateに setContentView(R.layout.activity_promotions_feed);以下のすべてのコードを削除し、その後、あなたのアダプタを変更

pfAdapter = new PromotionFeedAdapter(PromotionsFeedActivity.this, Title2); 
showData(pfAdapter); 

に置き換えます。

getViewで

：

switch(PromotionsFeedActivity.PartnerId.get(position)){ 
    case "5":layout=R.layout.livefeed_adapter;break; 
    case "3":layout=R.layout.livefeed_adapter_groupon;break; 
    case "null":layout=R.layout.livefeed_adapter_news;break; 
} 
convertView= inflater.inflate(layout,parent,false); 

、代わりに活性の切り替え。

クリーナーコードにはMapをお試しください。私は手書きで、Javaは長すぎてMapを使用することはできません。
