我正在尝试检查相应的文本是否与按钮中显示的图像相同。

例如显示字符串“heart”，我想知道按钮上显示的图像是否是心脏图像，如果加载了正确的图像，当您单击按钮时，计数器会增加。

        }

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.game, menu);
    return true;
}

 }

我对 Android 还是有点陌生​​。我不知道我想要的是否可能。有人可以帮忙。:(

您无法将 Drawable 与资源 ID 进行比较，这就是您正在做的事情：

if(img1.getBackground().equals(R.drawable.heart)){
    ...

也许您想要的是在设置时保存背景的资源ID，例如：

this.mImg1Bg = R.drawable.heart;
img1.setBackground(this.mImg1Bg);

然后在您测试的 onClick() 上：

if(this.mImg1Bg == R.drawable.heart) {
    ...

编辑：

现在有了整个代码，就更容易了。

我假设你在 onCreate() 的末尾有这个：

this.myImg1=R.drawable.heart;

仅出于测试目的，因为您正在重新定义它，因为它已经设置好了。

现在字符串测试还有另一个问题。形状变量不是您要测试的。也许如果你像这样测试它：

public void onClick(View v){

    String txt = ((Button)v).getText();
    if(txt.equals("Heart")){
        if(myImg1 == R.drawable.heart){
            correct++;
        } 
    }
    ...
}

我不知道您在活动中到底显示了什么，但在我看来，如果您使用以下内容，您可以简化很多：

HashMap<String, Integer> shapes;
shapes.put("Heart", R.drawable.heart);
...

存储形状字符串和与资源的关系。

一个 ArrayList of Pair，用于存储按钮上的组合：

ArrayList<Pair<Integer,String>> buts;
buts.add(new Pair<Integer,String>(R.drawable.heart, "Heart"));
...

在每个按钮视图上设置一个标签，以了解单击了哪个按钮编号：

img1.setTag(1);
...

然后将相同的 OnClickListener 分配给所有按钮。例如，通过您的 Activity 实现接口，例如：

public class Game extends Activity implements OnClickListener {

...

    img1.setOnClickListener(this);
    ...

并像这样检查 onClick() ：

    public void onClick(View v) {
        int res = buts.get((Integer)v.getTag()).first;
        String txt = buts.get((Integer)v.getTag()).second;
        if(res == shapes.get(txt)) {
            correct++;
        } 
    }

然后不要忘记将正确的分配给某些 UI TextView，以便您可以查看结果。
