我的应用每次都在这条线上崩溃

代码语言：javascript
复制
imageView.setImageBitmap(bitmap);

我绝对相信这是从那条线来的。这是我正在犯的错误：

它正在处理以下代码：

代码语言：javascript
复制
runOnUiThread(new Runnable() {
            @Override
            public void run() {
                imageView.setImageBitmap(bitmap);
            }
        });

然而，当我这样做之前，应用程序再次崩溃：

代码语言：javascript
复制
bitmap.setPixel(20, 20, Color.WHITE);

这是我得到的错误( MainActivity.java:111是这一行代码)：

复制
runOnUiThread(new Runnable() { 
imageView.setImageBitmap(bitmap)
 };

你可以试试这个

代码语言：javascript
复制
MainActivity.runOnUithread(new runnable()
{
imageView.setImageBitmap(bitmap);
});

这也许能行
