【问题描述】：

我希望列表视图打开一个新活动并在单击列表视图的某些行时显示某些信息。 到目前为止，我只能在单击每一行时显示相同的信息。我不知道如何为特定行设置这些信息，例如，当我单击第 1 行时会显示此地址，当我单击第 2 行时会显示另一个地址，并且.....我的代码如下

第一个活动

 // storing string resources into Array
 String []Buildings_halls = getResources().getStringArray(R.array.halls);
    // Binding resources Array to ListAdapter
    this.setListAdapter(new ArrayAdapter<String>(this, R.layout.hallstudent, R.id.listhall, Buildings_halls));

 

 protected void onListItemClick(ListView lv, View v, int position, long id)
     super.onListItemClick(lv, v, position, id);     

Intent intent = new Intent(StudentHall.this, StudentHallSelect.class);
Bundle bundle = new Bundle();
bundle.putInt("position", position);
// Or / And
intent.putExtra("id", String.valueOf(id));
intent.putExtra("description",getResources().getStringArray(R.array.hallsdescription));
intent.putExtras(bundle);
startActivity(intent);

                       

@Override
protected void onPause() 
    // TODO Auto-generated method stub
    super.onPause();
    finish();

第二次活动

        Bundle intent = getIntent().getExtras();

                if (intent !=null)
        int position = intent.getInt("position", 0);     

        String[] halldetails = getResources().getStringArray(R.array.hallsdescription);

        txt = (TextView) findViewById (R.id.select_details);
        txt.setText(halldetails[1]);

        txt2=(TextView)findViewById(R.id.details_select);
        txt2.setText(halldetails[0]); 

        // Here we turn your string.xml in an array
        String[] myKeys = getResources().getStringArray(R.array.halls);

        TextView myTextView = (TextView) findViewById(R.id.selecthalllist);
        myTextView.setText(myKeys[position]);


    


@Override
public boolean onCreateOptionsMenu(Menu menu) 
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;

即我要显示的第 1 行的信息

<string-array name="descriptions">
           <item>Address:</item>
                <item>  Contact: </item>
                      <item>OpeningHours:</item>
               </string-array>

即我要显示的第 1 行的信息

  <string-array name="hallsdescription">
           <item >Address:, Telephone No:,Opening Times:</item>
           <item >Address:Catherine Street, Telephone No:657263912739,Opening Times:23:00</item>

谢谢

【参考方案1】：

protected void onListItemClick(ListView lv, View v, int position, long id)
 super.onListItemClick(lv, v, position, id);     

    Intent intent = new Intent(StudentHall.this, StudentHallSelect.class);
    switch(position)
    case 0:
        intent.putExtra("description",getResources().getStringArray(R.array.hallsdescription)[0]);
        break;
    case 1:
        intent.putExtra("description",getResources().getStringArray(R.array.hallsdescription)[1]);
        break;
    
    startActivity(intent);
    

在你的第二个活动中，

txt.setText(getIntent().getExtras().getString("description"));
