获取资源ID Imageview（ImageViews数组）(Get resource id Imageview (array of ImageViews))

获取资源ID Imageview（ImageViews数组）(Get resource id Imageview (array of ImageViews))

如何检索android中的imageViews数组的resource_id？ 我知道如何让我获得可绘制的资源

int resId = context.getResources().getIdentifier("[imagename]" + indexNumber, "drawable", context.getPackageName());

但现在我想检索驻留在layout-folder（activity_main.xml）中的imageView的id

原因是除了indexnumer之外，我有10个不同的图像视图，其名称相似。

我的完整代码

ImageView[] imageView = new ImageView[10]; AnimationDrawable[] frameAnimation = new AnimationDrawable[10]; for (int i = 0; i < 10; i++) { int id = ??? imageView[i] = (ImageView) findViewById(id); imageView[i].setBackgroundResource(R.drawable.gold_coin_animation); // Get the background, which has been compiled to an AnimationDrawable object. frameAnimation[i] = (AnimationDrawable) imageView[i].getBackground(); frameAnimation[i].start(); }

imagevies的名字是

gold_coin_id1 gold_coin_id2 gold_coin_id3 ... gold_coin_id110

所以我想通过与indexnumber连接的前缀（gold_coin）来检索视图的resource-id

How do i retrieve the resource_id for an array of imageViews in android? I know how to get i for a drawable resource

int resId = context.getResources().getIdentifier("[imagename]" + indexNumber, "drawable", context.getPackageName());

But now I want to retrieve the id for an imageView which resides in the layout-folder (activity_main.xml)

The reason is that I have 10 different imageviews with similar names except the indexnumer.

My full code

ImageView[] imageView = new ImageView[10]; AnimationDrawable[] frameAnimation = new AnimationDrawable[10]; for (int i = 0; i < 10; i++) { int id = ??? imageView[i] = (ImageView) findViewById(id); imageView[i].setBackgroundResource(R.drawable.gold_coin_animation); // Get the background, which has been compiled to an AnimationDrawable object. frameAnimation[i] = (AnimationDrawable) imageView[i].getBackground(); frameAnimation[i].start(); }

The names of the imagevies are

gold_coin_id1 gold_coin_id2 gold_coin_id3 ... gold_coin_id110

So I want to retrieve the resource-id of the view by the prefix (gold_coin) concatenated with an indexnumber

最满意答案

这应该工作

int id = getResources().getIdentifier("gold_coin_id"+i, "id", getPackageName()); imageView[i] = (ImageView) findViewById(id);

This should work

int id = getResources().getIdentifier("gold_coin_id"+i, "id", getPackageName()); imageView[i] = (ImageView) findViewById(id);
