周围的GridView删除多余的空间编程 [英] Remove extra space around GridView programmatically

问题描述

我试图做一个GridView编程在我的Java类，这一切工作正常。问题是各地的GridView控件自动生成的5像素。在XML我设法删除它使用：

 的android：listSelector =@空
 

但我不设法做在java中类似的事情。我已经尝试了一些解决方法就像一个没有运气makeing GridView的10个像素越大，那么实际的屏幕。

没有人有任何code这个？

编辑：

由我的answear不解决问题。还有一个赏金去。
这里是我的GridView code：

  GridView控件的GridView =新的GridView（本）;
        gridView.setLayoutParams（新GridView.LayoutParams（customValue，LayoutParams.FILL_PARENT，Gravity.CENTER_HORIZONTAL））;
      gridView.setNumColumns（someInt）;
    gridView.setAdapter（新MyCustomAdapter（本））;
 

解决方案

• ，以确保填充的一种方式出现在不同的密度的屏幕同样是将其转换成DIP单位。

    INT填充= TypedValue.applyDimension（TypedValue.COMPLEX_UNIT_DIP，-5，
                                      。getResources（）getDisplayMetrics（））;
   




• 您可以尝试其他的事情是在XML中定义一个空的绘制。

   ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
  ＆LT;资源＆GT;
      ＆LT;绘制NAME =null_drawable＆GT; @空＆LT; /绘＆GT;
      ...
  ＆LT; /资源＆GT;
   

  然后调用 setSelector（R.drawable.null_drawable）;

更新：的

• 定义你的 GridView控件在其自己的XML和它充气。

  的布局/ mygrid.xml 的

   ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
  ＆LT; GridView控件
      机器人：layout_width =FILL_PARENT
      机器人：layout_height =FILL_PARENT
      机器人：listSelector =@空/＆GT;
   

  在Java中，

    GridView控件的GridView =（GridView控件）inflater.inflate（R.layout.mygrid，NULL）;
  gridView.setLayoutParams（新GridView.LayoutParams（customValue，
                          LayoutParams.FILL_PARENT））;
  gridView.setNumColumns（someInt）;
  gridView.setAdapter（新MyCustomAdapter（本））;
   

I am trying to make a GridView programmatically in my java class and it all works fine. The problem is the autogenerated 5 pixel padding around the GridView. In xml I manage to remove it using:

android:listSelector="@null"

But I do not manage to do anything similar in java. I have tried some workarounds like makeing the GridView 10 pixels larger then the actual screen with no luck.

Does anyone have any code for this?

Edit:

The answear by me does not solve the problem. There is still a bounty going. Here is my GridView code:

        GridView gridView= new GridView(this);
        gridView.setLayoutParams(new GridView.LayoutParams(customValue,LayoutParams.FILL_PARENT, Gravity.CENTER_HORIZONTAL));
      gridView.setNumColumns(someInt);
    gridView.setAdapter (new MyCustomAdapter(this));

解决方案

• One way to ensure the padding appears same on screens with different density is by converting it to DIP units.

  int padding = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, -5, 
                                      getResources().getDisplayMetrics());
  

• Other thing you can try is to define a null drawable in xml..

  <?xml version="1.0" encoding="utf-8"?>
  <resources>
      <drawable name="null_drawable">@null</drawable>
      ...
  </resources>
  

  Then call setSelector(R.drawable.null_drawable);

Update:

• Define your GridView in its own xml and inflate it.

  layout/mygrid.xml

  <?xml version="1.0" encoding="utf-8"?>
  <GridView 
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:listSelector="@null"/>
  

  In java,

  GridView gridView = (GridView)inflater.inflate(R.layout.mygrid, null);
  gridView.setLayoutParams(new GridView.LayoutParams(customValue, 
                          LayoutParams.FILL_PARENT));
  gridView.setNumColumns(someInt);
  gridView.setAdapter (new MyCustomAdapter(this));
