更改图像视图背景动态 [英] Changing image view background dynamically

问题描述

我有一个在我的布局了一套10 imageviews。我已经给了他们连续的ID也为

I have a a set of 10 imageviews in my layout. I have given them sequential id's also as

android:id="@+id/pb1"

android:id="@+id/pb2"

现在我要动态地改变背景。

Now I want to change background dynamically.

    int totalPoi = listOfPOI.size();
    int currentPoi = (j/totalPoi)*10;
    for (i=1;i<=currentPoi;i++) {
          imageview.setBackgroundResource(R.drawable.progressgreen);
}

现在里面的for循环我想动态设置图像视图背景。 I，E，如果currentpoi值是3，3图像视图背景应该有所改变。什么都时代的for循环遍历许多图像视图的背景应该有所改变。希望这个问题是清楚了吧。

Now inside the for loop I want to set the image view background dynamically. i,e if the currentpoi value is 3, background of 3 image views should be changed. What ever the times the for loop iterates that many image view's background should be changed. Hope the question is clear now.

请注意：我需要被设置为10的图像观点仅1图像progressgreen

Note : I have only 1 image progressgreen that need to be set to 10 image views

推荐答案

最后，我以下列方式这样做，

Finally I did this in the following way,

我把所有的ID的数组中为

I placed all the id's in the array as

INT [] = imageViews {R.id.pb1，R.id.pb2，

int[] imageViews = {R.id.pb1, R.id.pb2,

R.id.pb3，R.id.pb4，R.id.pb5，R.id.pb6，R.id.pb7，R.id.pb8，R.id.pb9，R.id.pb10 };

R.id.pb3,R.id.pb4,R.id.pb5,R.id.pb6,R.id.pb7,R.id.pb8,R.id.pb9,R.id.pb10};

 Now, 
    int pindex = 0;

    for (pindex; pindex <currentPoi; pindex++) {

        ImageView img = (ImageView) findViewById(imageViews[pindex]) ;
        img.setImageResource(R.drawable.progressgreen);
    }

现在，我能够动态地改变图像。

Now, I am able to change the images dynamically.
