设置图像视图绝对位置 [英] Setting image view absolute position

问题描述

我正在尝试手动设置我的应用程序中的图像视图位置，代码当前正在工作，但所有的Facebook图像显示在彼此的右上角和侧边。

我无法访问任何适配器，这在Facebook SDK中，任何人都可以发现以下代码的任何问题：

我的XML：

DisplayPhotos.xml

 <？xml version =1.0encoding =utf-8？> 
< RelativeLayout xmlns：android =http://schemas.android.com/apk/res/android
 android：id =@ + id / DisplayPhotosLayout
 android：layout_width =match_parent
 android：layout_height =match_parent> 
< / RelativeLayout> 
  

这是由以下设置：

  fbManager = new FBLoginManager（this，R.layout.displayphotos，-------，permissions）; 
  

然后我使用以下内容显示图像（工作但都位于相同的位置）

  int Row = 0; 
 int RowCount = 0; 
 int imageWidth =（int）getWindowManager（）。getDefaultDisplay（）。getWidth（）/ 3; 
 
 for（int _i = 0; _i< _noOfPhotos; _i ++）
 {
 ImageView imageView = new ImageView（getApplicationContext（））; 
 imageView.setImageResource（R.drawable.no_image）; 
 
 RelativeLayout.LayoutParams rl = new RelativeLayout.LayoutParams（imageWidth，imageWidth）; 
 rl.setMargins（imageWidth * _i，imageWidth * Row，0,0）; 
 
 RowCount = RowCount + 1; 
 
 if（RowCount == 3）{Row = Row + 1; RowCount = 0;} 
 
 UrlImageViewHelper.setUrlDrawable（imageView，_userGallery.get（_i）.getPicture ））; 
 
 addContentView（imageView，rl）; 
 
 System.out.println（imageWidth * _i +top：+ imageWidth * Row）; 
 
 _imageViewArray.add（imageView）; 
} 
  

解决方案

我想你需要一张桌子布局， http://developer.android.com/guide/topics/ui /layout/grid.html

I'm trying to manually set the image-view position within my app, the code is currently working but all the facebook images display at the top right and side on top of each other.

I do not have access to any adaptors, this is within the Facebook SDK, can anyone spot any problems with the following code:

My XML:

DisplayPhotos.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/DisplayPhotosLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
</RelativeLayout>

This is set by the following:

fbManager = new FBLoginManager(this, R.layout.displayphotos, "-------", permissions);

Then I use the following to display images (working but all in same position)

int Row = 0;
    int RowCount = 0;
    int imageWidth = (int)getWindowManager().getDefaultDisplay().getWidth() / 3;

    for(int _i = 0; _i < _noOfPhotos; _i++)
    {
        ImageView imageView = new ImageView(getApplicationContext());
        imageView.setImageResource(R.drawable.no_image);

        RelativeLayout.LayoutParams rl = new RelativeLayout.LayoutParams(imageWidth, imageWidth);
        rl.setMargins(imageWidth * _i, imageWidth * Row, 0,0);

        RowCount = RowCount + 1;

        if(RowCount == 3){Row = Row + 1;RowCount = 0;}

        UrlImageViewHelper.setUrlDrawable(imageView, _userGallery.get(_i).getPicture());

        addContentView(imageView, rl);

        System.out.println(imageWidth * _i + " top: " + imageWidth * Row);

        _imageViewArray.add(imageView);
    }

解决方案

I think you need a table layout, http://developer.android.com/guide/topics/ui/layout/grid.html
