在Android应用程序的ListView内的ListView

Question

我正在做一个项目，目前需要一个列表，当列表中的特定项目被点击时，出现另一个列表活动。是否有任何解决方案，以便如何从一个listview活动转移到另一个。我目前使用http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/作为我的ListView的参考。

Answer 1

一个解决办法是：

创建第二个ListView的活动并实施，通过使用常规的意图打开第二ListViewActivity一个OnItemClickListener第一ListActivity。

listView = (ListView) findViewById(R.id.mylistview); 
     listView.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> arg0, View v, int position, 
        long arg3) { 

       Intent intent = new Intent(FirstListActivity.this, SecondListActivity.class); 
       Bundle bundle = new Bundle(); 
       bundle.putString("pos", position); 
       intent.putExtras(bundle); 
       startActivity(intent); 
      } 
     }); 

UPDATE：

我已经写了一个简单的例子列表应用程序。您可以使用它进行检查。包含可以打开第二个列表活动的代码，但注释掉了。如果你得到这个例子，你就会越来越近。然后你可以尝试注释掉Intent代码。

public class MainActivity extends Activity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     // Find the ListView resource. 
     ListView mainListView = (ListView) findViewById(R.id.my_list); 

     // Set the Adapter as the ListView's adapter. 
     mainListView.setAdapter(new BaseAdapter(){ 

      // Create and populate a List of planet names. 
      String[] planets = new String[] {"Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Neptune" };  

      @Override 
      public int getCount() { 
       return planets.length; 
      } 

      @Override 
      public Object getItem(int pos) { 
       return planets[pos-1]; 
      } 

      @Override 
      public long getItemId(int pos) { 
       return 0; 
      } 

      @Override 
      public View getView(int pos, View view, ViewGroup viewgroup) { 
       if(view == null){ 
        /**

        */ 
        view = View.inflate(getApplicationContext(), R.layout.row, null); 
       } 
       return view; 
      } 
     });   

     mainListView.setOnItemSelectedListener(new OnItemSelectedListener() { 

      @Override 
      public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
       Log.d("ListView", "Pos: " + arg2 + ", long : "+arg3); 
       Toast.makeText(getApplicationContext(), "Test " + arg2, Toast.LENGTH_SHORT).show(); 
       /* Alternative way; opens a new Activity 
       Intent intent = new Intent(this, SecondListViewActivity.class); 
       intent.putExtra("position", pos); 
       startActivity(intent); 
       */ 
      } 

      @Override 
      public void onNothingSelected(AdapterView<?> arg0) { 
      } 
     }); 

     /** 
     * Implement an action for each item click. 
     */ 
     mainListView.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
       Log.d("ListView", "OnClickPos: " + arg2 + ", long : "+arg3); 
       Toast.makeText(getApplicationContext(), "Test " + arg2, Toast.LENGTH_SHORT).show(); 
      } 
     }); 
    } 
}

api规定了ExpandableListView。您的要求看起来非常接近它
