遍历图像

Question

我有100个图像，每个图像的百分比，例如1％，2％，3％等。

什么是通过每个图像的最佳方式？我应该将每个图像资源添加到列表或词典（如果存在于Android中）。还是我被迫硬编码？

public void ShowCircle(final int percentage){ 
    final ImageView ring = (ImageView)findViewById(R.id.ring); 
    ring.setOnClickListener(new View.OnClickListener() { 

      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       for(int i = 0; i != percentage; i++) 

          //I was thinking here I can access list/dictionary records. 
       ring.setImageResource(R.drawable.percent_1); 
      } 
     }); 
} 

Answer 1

在OP的要求，从评论一copypasta回答：

看一看How do I iterate through the id properties of R.java class?和Android: Programatically iterate through Resource ids。

...虽然这个问题应该只是作为一个dup被关闭。

Answer 2

你可以把它们放入数组（关于如何添加到一个数组信息发现here），然后重复trhough他们的foreach循环，像这样：

for(ImageView image : ImageArray) { 
    // Do stuff with your image that is now in the variable called image. 
    // All images will be called in the order that they are positioned in the array 
} 

Answer 3

我会把他们成这样

public static int[] picArray = new int[100]; 
picArray[0] = R.raw.img1; 
picArray[1] = R.raw.img2; 
//etc  

阵列和遍历它们这样

public void onClick(View view) 
{ 

    ImageView image = (ImageView) findViewById(R.id.imageView1); 

    if(counter== (picArray.length - 1)) 
    { 
     counter =0; 


    } 
    else 
    { 
     counter++; 

    } 
    image.setImageResource(picArray[counter].getImg()); 

}
