Question

我需要通过图像资源(在纽芬兰使用的图像)或图像资源档案馆对两个图像词进行对比。

大致如下:

final ImageView button01 = (ImageView) findViewById(R.id.button01);
final ImageView button02 = (ImageView) findViewById(R.id.button02);
button01.setImageResource(R.drawable.myDogsPhoto);
button02.setImageResource(R.drawable.myDogsPhoto);
if (button01.getImageResource() == button02.getImageResource()) {
return true;
}

Can someone please tell me how I can go about comparing two ImageView components?

一种可能的方法是使用储存资源价值(或档案铺设)。既定的“Tag()”和“Tag()”方法允许你将任意数据附在“观点”的后面,以达到你所需要的任何目的。

例如:

final ImageView button01 = (ImageView) findViewById(R.id.button01);
final ImageView button02 = (ImageView) findViewById(R.id.button02);

button01.setImageResource(R.drawable.myDogsPhoto);
button01.setTag(R.drawable.myDogsPhoto);
button02.setImageResource(R.drawable.myDogsPhoto);
button02.setTag(R.drawable.myDogsPhoto);
if (button01.getTag().equals(button02.getTag())) {
    return true;
}

Note I didn t compile this, it might want you to make Integer objects to pass to setTag().

我也不知道,这是否是你想要做的事情的最佳途径,但这是头脑。

对比图2 View

button01 =(ImageView)findViewById(R.id.button01 );
button02 =(ImageView)findViewById(R.id.button02 );

Drawable d=button01 .getDrawable();
Drawable d1=button02 .getDrawable();
if( d== d1){
     Toast.makeText(Example.this, "hello", Toast.LENGTH_SHORT).show();
}else {
    Toast.makeText(Example.this, "hai", Toast.LENGTH_SHORT).show();
}
