Question

在我的代码中，我根据数据库值动态创建一些按钮。这些按钮我放在水平滚动视图中。按下每个按钮，我显示一个不同的页面。现在我的问题是从右向左拖动屏幕我们需要显示下一页，下一个按钮也将突出显示，并且从左向右拖动前一个按钮的页面应该显示，该按钮应该突出显示。

我的代码是：

Cursor c = sqldb.rawQuery("select Diameter from ProductDetailMetric where ProductId=1", null);
            n=c.getCount();             
            arr = new String[c.getCount()];

            int i = 0;


            for (c.moveToPosition(-1); c.moveToNext(); c.isAfterLast()) {


                arr[i] = c.getString(0);
                Log.e("","no.of values----"+"--"+arr[i]);

                i++;
            }
        }
    }
    catch(Exception e){
        System.out.println(e.toString());

    }


   ll=(LinearLayout)findViewById(R.id.lll);

 for(int i=0;i<arr.length;i++){
       final Button b=new Button(this);

       b.setWidth(80);
       b.setText(arr[i]);

       ll.addView(b);

       b.setOnClickListener(new OnClickListener(){

           @Override
           public void onClick(View v) {
            // TODO Auto-generated method stub
           b.getText(); 
           Log.e("","value---"+b.getText());


           Cursor c1 = sqldb.rawQuery("select *from ProductDetailMetric where Diameter="+b.getText()+" and ProductId=1", null);
           for (c1.moveToPosition(-1); c1.moveToNext(); c1.isAfterLast()) {

           Log.e("","value---0"+c1.getString(0));
           Log.e("","value---1"+c1.getString(1));
           Log.e("","value---2"+c1.getString(2));
           Log.e("","value---3"+c1.getString(3));
           Log.e("","value--4-"+c1.getString(4));
           Log.e("","value---5"+c1.getString(5));
           e1.setText(c1.getString(8));
           e2.setText(c1.getString(9));
           e3.setText(c1.getString(10));
           e4.setText(c1.getString(11));
           e5.setText(c1.getString(12));
           e6.setText(c1.getString(13));
           e7.setText(c1.getString(14));
           e8.setText(c1.getString(15));
           e9.setText(c1.getString(16));
           e10.setText(c1.getString(17));

           }
          }
        });
 }
