我正在编写一个Android应用程序,当用户单击gif图像时,我想在两个GIF之间切换。
我写了下面的代码来在gif之间切换。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gifImageView = (GifImageView) findViewById(R.id.GifImageView);
gifImageView.setGifImageResource(R.drawable.seat_animation0);
gifImageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
gifImageView.closeInputStream();
animChange = !animChange;
if(true == animChange) {
gifImageView.setGifImageResource(R.drawable.seat_animation1);
} else {
gifImageView.setGifImageResource(R.drawable.seat_animation0);
}
}
});
}
" setGifImageResource"的代码是
public void setGifImageResource(int id) {
mInputStream = mContext.getResources().openRawResource(id);
init();
}
private void init() {
setFocusable(true);
mMovie = Movie.decodeStream(mInputStream);
mWidth = mMovie.width();
mHeight = mMovie.height();
requestLayout();
}
OnDraw方法如下
@Override
protected void onDraw(Canvas canvas) {
long now = SystemClock.uptimeMillis();
if (mStart == 0) {
mStart = now;
}
if (mMovie != null) {
int duration = mMovie.duration();
if (duration == 0) {
duration = 1000;
}
int relTime = (int) ((now - mStart) % duration);
mMovie.setTime(relTime);
mMovie.draw(canvas, 0, 0);
invalidate();
}
}
问题是当我长时间在GIF之间切换时。应用程序崩溃,但日志中没有致命错误。只有我可以看到以下日志。
