java - Android Java Switch 语句失败 - 堆大小？

Question

这个问题已经有答案了:

Android Switch Statement Crashing (1 个回答)

已关闭 8 年前。

我已经在 android studio 中编写了这个 switch 语句，但是每当模拟器运行时它就会崩溃，因为它说设备内存不足。每个图像只有 20kb，但我想我需要增加“堆”大小或其他名称？抱歉，我是安卓新手。我将包含在下面的调试器中显示的 switch 语句和错误消息。提前感谢您的帮助:)

Java Switch 语句

    rating = 5;

    switch(rating){
    case 0: 
            ratingBar.setImageResource(R.drawable.star0);
            break;

    case 1: 
            ratingBar.setImageResource(R.drawable.star05);
            break;

    case 2:
            ratingBar.setImageResource(R.drawable.star1);
            break;

    case 3:
            ratingBar.setImageResource(R.drawable.star15);
            break;
    case 4:
            ratingBar.setImageResource(R.drawable.star2);
            break;
    case 5:
            ratingBar.setImageResource(R.drawable.star25);
            break;
    case 6:
            ratingBar.setImageResource(R.drawable.star3);
            break;
    case 7:
            ratingBar.setImageResource(R.drawable.star35);
            break;
    case 8:
            ratingBar.setImageResource(R.drawable.star4);
            break;
    case 9:
            ratingBar.setImageResource(R.drawable.star45);
            break;
    case 10:
            ratingBar.setImageResource(R.drawable.star5);
            break;
    }

还可以尝试通过编辑模拟器来增加模拟器内存​​。
