尝试使用 if 语句设置图像资源时强制关闭

Question

您好，我的教授无法解决这个问题，所以我想我会在这里发帖。我正在尝试制作一个显示温度的应用程序，当搜索栏达到某个温度时，我希望在 imageView 中显示不同的图像。当我测试应用程序并且搜索栏超过 40 时，应用程序取消抵押品赎回权。谁能告诉我这是为什么？

SeekBar seekBar;
TextView f, c;
ImageView i;
int progress_value;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tempature);

    seekBar = (SeekBar)findViewById(R.id.seekBar);
    seekBar.setMax(200);
    f = (TextView)findViewById(R.id.f);
    c = (TextView)findViewById(R.id.c);
    i = (ImageView)findViewById(R.id.imageView);

    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            progress_value = progress;

            f.setText(" " + progress_value);
            c.setText(" " + .55 * (progress_value - 32));

            if (progress_value <= 40){
                i.setImageResource(R.drawable.cold);
            }
            else if (progress_value > 40 && progress_value < 90){
                i.setImageResource(R.drawable.justright);
            }
            else{
                i.setImageResource(R.drawable.hot);
            }
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    });

}

}

Answer 1

无法在运行时更改可绘制图像。因此，您的应用程序正在崩溃。 我想提出一个修复。尝试将您的可绘制图像转换为位图，然后根据您的需要更改位图。

Answer 2

使用毕加索，这样的东西对我有用

ImageView img1 = (ImageView)findViewById(R.id.chamb_img);
Picasso.with(this).load(R.drawable.h).resize(75,75).into(img1);
