在Horizo​​ntalScrollView的RelativeLayout中以编程方式在ImageView上显示textView

Question

我想在horizo​​ntalScrollView中的每个图像上显示图像和文本。 为此我在horizo​​ntalScrollView中使用RelativeLayout并动态添加ImageView和TextView。它如下所示。图像仅显示文本长度。 text1 text2 text3 text4 text5 text6 |   | | | | | | | I1 | i2 | i3 | i4 | i5 | i6 | i7 |
  | | | | | | | 以下是我的代码。

         for (int j = 0; j < 7; j++){                       
                         imageView = new ImageView (con);
                         textView=new TextView(con);                          
                         imageView.setId(50+j);
                         textView.setId(50+j);

                        //set image to imageView
                         new vdoImageLoader(videos.get(j),imageView,con).execute(null, null);

                     if (j == 0) {
                            RelativeLayout.LayoutParams rlp1 = new RelativeLayout.LayoutParams(
                                      RelativeLayout.LayoutParams.WRAP_CONTENT,
                                       RelativeLayout.LayoutParams.WRAP_CONTENT);

                              rlp1.addRule(RelativeLayout.ALIGN_PARENT_TOP);
                               rlp1.addRule(RelativeLayout.ALIGN_PARENT_LEFT);

                               imageView.setLayoutParams(rlp1);
                             vdoRelativeLayout.addView(imageView);

                           RelativeLayout.LayoutParams rlp2 = new RelativeLayout.LayoutParams(
                                   RelativeLayout.LayoutParams.WRAP_CONTENT,
                                   RelativeLayout.LayoutParams.WRAP_CONTENT);   

                          rlp2.addRule(RelativeLayout.ALIGN_BOTTOM, imageView.getId());   

                           textView.setLayoutParams(rlp2);
                           vdoRelativeLayout.addView(textView);                         

                       } else {

                           RelativeLayout.LayoutParams rlp2 = new RelativeLayout.LayoutParams(
                                  RelativeLayout.LayoutParams.WRAP_CONTENT,
                                   RelativeLayout.LayoutParams.WRAP_CONTENT);

                           rlp2.addRule(RelativeLayout.RIGHT_OF, imageView.getId() - 1);

                           imageView.setLayoutParams(rlp2);
                             vdoRelativeLayout.addView(imageView);

                         RelativeLayout.LayoutParams rlp1 = new RelativeLayout.LayoutParams(
                                   RelativeLayout.LayoutParams.MATCH_PARENT,
                                   RelativeLayout.LayoutParams.MATCH_PARENT);   

                         rlp1.addRule(RelativeLayout.RIGHT_OF, imageView.getId()-1); 
                         rlp1.addRule(RelativeLayout.ALIGN_BOTTOM, imageView.getId()-1); 

                           textView.setLayoutParams(rlp1);
                           vdoRelativeLayout.addView(textView);     
                       }                                                  
                     }
