将下面的行替换为

File file = new File(filename);

代码如下：

您需要在下面的行中添加文件路径

// load image
try {
    // get input stream
    InputStream inputstream= getAssets().open("imgs/"+filename);
    // load image as Drawable
    Drawable drawable = Drawable.createFromStream(inputstream, null);
    // set image to ImageView
    mImage.setImageDrawable(drawable );
}
catch(IOException ex) {
    return;
}

您好，您是否尝试过重命名资产。用下划线重命名连字符。

// load image
try {
    // get input stream
    InputStream inputstream= getAssets().open("imgs/"+filename);
    // load image as Drawable
    Drawable drawable = Drawable.createFromStream(inputstream, null);
    // set image to ImageView
    mImage.setImageDrawable(drawable );
}
catch(IOException ex) {
    return;
}
