我在android中使用animationview来显示gif文件。它在姜饼上运行良好,但没有在ICS上运行。 在android上运行它应该怎么办? 我指的是以下代码: -
public class AnimationView extends View {
private Movie mMovie;
private long mMovieStart;
private static final boolean DECODE_STREAM = true;
private static byte[] streamToBytes(InputStream is) {
ByteArrayOutputStream os = new ByteArrayOutputStream(1024);
byte[] buffer = new byte[1024];
int len;
try {
while ((len = is.read(buffer)) >= 0) {
os.write(buffer, 0, len);
}
} catch (java.io.IOException e) {
}
return os.toByteArray();
}
public AnimationView(Context context,AttributeSet attrs) {
super(context,attrs);
setFocusable(true);
java.io.InputStream is;
is = context.getResources().openRawResource(R.drawable.applogo);
if (DECODE_STREAM) {
mMovie = Movie.decodeStream(is);
} else {
byte[] array = streamToBytes(is);
mMovie = Movie.decodeByteArray(array, 0, array.length);
}
}
@Override
public void onDraw(Canvas canvas) {
long now = android.os.SystemClock.uptimeMillis();
if (mMovieStart == 0) { // first time
mMovieStart = now;
}
if (mMovie != null) {
int dur = mMovie.duration();
if (dur == 0) {
dur = 3000;
}
int relTime = (int) ((now - mMovieStart) % dur);
Log.d("", "real time :: " +relTime);
mMovie.setTime(relTime);
mMovie.draw(canvas, getWidth()-300, getHeight()-375);
invalidate();
}
}
}
请提出一些建议。 。
