我正在尝试在 onDraw 方法中使用 android Movie 类在 ImageView 中显示动画 gif，如下所示:
@Override
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.TRANSPARENT);
super.onDraw(canvas);
long now = android.os.SystemClock.uptimeMillis();
if (movieStart == 0) {
movieStart = now;
}
movie = getMovieFromGif();
if (movie != null && movie.duration() > 0) {
try {
int relTime = (int) ((now - movieStart) % movie.duration());
movie.setTime(relTime);
float movie_height = convertDpToPixels(movie.height());
float movie_width = convertDpToPixels(movie.width());
float new_movie_height = movie_height;
float new_movie_width = movie_width;
float movie_ratio = movie_width / movie_height;
if (new_movie_width > container_width) {
new_movie_width = container_width;
new_movie_height = new_movie_width / movie_ratio;
}
if (new_movie_height > container_height) {
new_movie_height = container_height;
new_movie_width = new_movie_height * movie_ratio;
}
float scale_x = container_width / new_movie_width;
float scale_y = container_height / new_movie_height;
scale_x = new_movie_width / (float) movie.width();
scale_y = new_movie_height / (float) movie.height();
canvas.scale(scale_x, scale_y);
float x = 0;
if ((float) this.getWidth() > new_movie_width) {
x = ((this.getWidth() - (movie.width() * scale_x)) / 2f)
/ scale_x;
}
movie.draw(canvas, x, 0);
this.invalidate();
} catch (Exception ex) {
Log.i("onDraw()", "Error: " + ex.getMessage());
}
}
}
代码在大多数设备上运行良好，但在华为 Ascend P7 和三星 galaxy a5 上，应用程序在 movie.draw(canvas, x, 0) 上崩溃，异常:
A/libc(23632): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 23632
知道这些设备上的 movie.draw 有什么问题吗？
更新: 以下是完整的堆栈跟踪

执行代码movie.draw()后发生致命信号错误，其余为执行movie.draw()之前行的堆栈跟踪。
最佳答案
我能够通过禁用 android 硬件加速来解决问题:
android:hardwareAccelerated="false"
关于java - Android:movie.draw 上 0x00000000(代码=1)处的致命信号 11 (SIGSEGV)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29816897/
