java - 在 LinearLayouts 之间添加空间

Question

我正在尝试制作一个数据库项目列表，如下所示..

   for (int i=0; i < jArray.length(); i++)
           {

               JSONObject row = jArray.getJSONObject(i);

               LinearLayout ll = new LinearLayout(MainActivity.this);
               ll.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,100));

               Button btn = new Button(MainActivity.this);
               //btn.setText(row.getString("subject"));
               btn.setText(String.valueOf(i));
               btn.setLayoutParams(new LinearLayout.LayoutParams(0,LinearLayout.LayoutParams.MATCH_PARENT,(float)0.8));


               File imgFile = new  File(file_path);

               Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());

               ImageView iv = new ImageView(MainActivity.this);
               iv.setScaleType(ImageView.ScaleType.FIT_XY);
               iv.setImageBitmap(myBitmap);
               iv.setLayoutParams(new LinearLayout.LayoutParams(0,LinearLayout.LayoutParams.MATCH_PARENT,(float)0.2));




               ll.addView(btn);
               ll.addView(iv);

               LinearLayout sv = findViewById(R.id.sv_layout);
               sv.addView(ll);

           }

结果是这样的：

但我想在线性布局之间留出空间并使图像高度更短以与按钮高度相等

我怎样才能做到这一点？谢谢，

请尝试此代码

  LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 100);
                    params.setMargins(0, 5, 5, 10);
                    ll.setLayoutParams(params);

您可以在此行中添加您的特定边距params.setMargins(0, 5, 5, 10);
