Question

这就是我定义的listview数组。

private String lv_arr[] = {"number1", "number2", "number3", "number4"};

如何更改要与number1.java，number2.java，number3.java和number4.java关联的内容？

像这样使用。

setListAdapter(new ArrayAdapter(this, android.R.layout.simple_expandable_list_item_1, Categories));
    ListView lv = getListView();      
lv.setTextFilterEnabled(true);
    lv.setOnItemClickListener(new OnItemClickListener() {
          public void onItemClick(AdapterView<?> parent, View v,int position, long id) {

              switch (position){
              case 0: Intent animalsGridViewIntent = new Intent(ListOfAppGallery.this,N1.class);     
                      ListOfAppGallery.this.startActivity(animalsGridViewIntent);
                      break;
              case 1: Intent calenderGridViewIntent = new Intent(ListOfAppGallery.this,N2.class);     
                      ListOfAppGallery.this.startActivity(calenderGridViewIntent);
                      break;
              case 2: Intent carsGridViewIntent = new Intent(ListOfAppGallery.this,N3.class);     
                      ListOfAppGallery.this.startActivity(carsGridViewIntent);
                      break;
              case 3: Intent creativeGridViewIntent = new Intent(ListOfAppGallery.this,N4.class);     
                      ListOfAppGallery.this.startActivity(creativeGridViewIntent);
                      break;

          }
      }
   });    
}

抓住您的列表视图： listView.setOnItemOnClickListener()并检查案例检查以开始新活动：

listView.setOnItemClickListener(new OnItemClickListener(){

                @Override
                public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {
                                        Intent intent;
                    switch (position) {
                    case 1:
                        intent=new Intent(getApplicationContext(),NumberOne.java)
                        getApplicationContext().startActivity(intent);
                        break;
                    case 2:
                        intent=new Intent(getApplicationContext(),NumberTwo.java);
                        getApplicationContext().startActivity(intent);
                        break;
                    case 3:
                        intent=new Intent(getApplicationContext(),NumberThree.java);
                        getApplicationContext().startActivity(intent);
                        break;
                    case 4:
                        intent=new Intent(getApplicationContext(),NumberFour.java);
                        getApplicationContext().startActivity(intent);
                        break;
                    default:
                        break;
                    }
                }

}）;

你怎么做到这一点？
