问题描述
我正在开发一个Android应用程序,试图在其中显示GIF图像。
为此,我正在使用Movie类,并创建了一个GIFView类来扩展View。我从Movie.decodeFile方法获取一个Movie实例。
I'm developing an Android application in which I'm trying to display a GIF image.For that I am using the Movie class and created a class GIFView that extends View. I getting a Movie instance from Movie.decodeFile method.
调用Movie.draw(canvas)时出现错误。
I am getting an error when Movie.draw(canvas) is called.
04-28 13:44:18.001: A/libc(24883): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 24883 (mple.channel002)
有相关代码:
public void setGif(File gif)
{
movie = Movie.decodeFile(gif.getAbsolutePath());
}
@Override
public void draw(Canvas canvas) {
// TODO Auto-generated method stub
super.draw(canvas);
canvas.drawColor(0xFFCC3C6C);
if(movie != null)
{
if(movieStart == 0)
movieStart = android.os.SystemClock.uptimeMillis();
int duration = Math.max(movie.duration(), 1000);
movie.setTime((int)(duration - ((android.os.SystemClock.uptimeMillis() - movieStart)%duration)));
movie.draw(canvas, 10, 10);//TODO CRASH
invalidate();
}
}
我在主方法中创建了一个GIFView,调用setGIF方法上面提供路径,并使用FillParent参数将其添加到布局中。
当我在ImageView中打印此图像时,它可以工作。
也可以在画布上绘制可绘制对象而不是GIF。
所以问题似乎与Movie实例有关。
I create a GIFView in the main, call setGIF method above to give it the path and add it to the layout with FillParent parameter.It works when I print this image in an ImageView.Drawing a drawable in the canvas instead of the GIF works too.So the problem seems to deals with the Movie instance.
我使用了这些链接来制作GIFView
I used these links to make the GIFViewhttp://weavora.com/blog/2012/02/07/android-and-how-to-use-animated-gifs/
我也尝试过这种方法,但是movie.draw $ b $出现了相同的错误b
I also tried it this way but same error on movie.drawInfo about the Movie class for Android
编辑1:
我在Android 4.4.2 / snapdragon 801 / 2GB上的Oppo Find 7a上进行测试更改movie.draw(canvas,10,10)为movie.draw(canvas,10f,10f)不变。
I do my tests on an Oppo Find 7a on Android 4.4.2 / snapdragon 801 / 2GBChanging movie.draw(canvas, 10, 10) to movie.draw(canvas, 10f, 10f) doesn't change anything.
EDIT2:
我刚刚在装有Android的旧ZTE设备上进行了测试2.3.5并有效。.
在Find7a设备上启动时出了点问题,但我不知道是什么:(
推荐答案
最后,我发现了
答案似乎是在某些Android版本或设备上需要禁用硬件加速。
我刚刚将此添加到清单中:
FINALLY!I found the answer, it appears that on some Android version or devices hardware acceleration needs to be disabled.
I just added this this to my manifest:
<application android:hardwareAccelerated="true" ...>
有关使用启用/禁用硬件加速的更多信息,请参见。
More information on using enabling/disabling hardware acceleration can be found here.
