"findViewById"；与for循环 [英] "findViewById" with for loop

问题描述

这是我的代码:

ImageView img1 = (ImageView) findViewById(R.id.img1);
ImageView img2 = (ImageView) findViewById(R.id.img2);
ImageView img3 = (ImageView) findViewById(R.id.img3);
ImageView img4 = (ImageView) findViewById(R.id.img4);
ImageView img5 = (ImageView) findViewById(R.id.img5);
ImageView img6 = (ImageView) findViewById(R.id.img6);
ImageView img7 = (ImageView) findViewById(R.id.img7);
ImageView img8 = (ImageView) findViewById(R.id.img8);
ImageView img9 = (ImageView) findViewById(R.id.img9);

我想创建类似这样的东西:

I d like to create something like this:

     for (int i=1; i<=9; i++) { 
ImageView img+i = (ImageView) findViewById(R.id.img+i);}

我该怎么办?

推荐答案

做到这一点.您可以从存储在xml或代码中的数组中获取可绘制的名称.

Do It like this. You can get drawable names from array stored in xml or code.

for (int i=1; i<=9; i++) { 

int id = getResources().getIdentifier("drawableName", "drawable", context.getPackageName());

ImageView img = (ImageView) findViewById(id);
}

"drawableName"是图片的名称，请保留"drawable".

Here "drawableName" is the name of your image and leave "drawable" as is.
