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。我正在尝试创建一个显示温度的应用程序，当搜索栏达到某个临时值时，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，应用程序取消预审。谁能告诉我为什么会这样？
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) {
}
});
}
}

可绘制的图像无法在运行时更改。因此，您的应用程序崩溃了。 我想提出一个修复方案。尝试将可绘制图像转换为位图，然后根据所需条件更改位图。

使用Picasso，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);
