我正在尝试从Http服务器加载图像切换器中的图像。我找不到像setImageBitmap这样的函数。所以我尝试使用setImageURI(),但它没有加载。 我每隔3秒钟就会切换一次图像。这是代码。当我运行代码时,图像没有被加载。而app也变得很疯狂。
String arr[]={"http://192.168.1.7/photos/dummy/1.jpg","http://192.168.1.7/photos/dummy/2.jpg","http://192.168.1.7/photos/dummy/3.jpg"}
dailyWear = (ImageSwitcher) getActivity().findViewById(R.id.imageDailyWear);
dailyWear.setFactory(new ViewSwitcher.ViewFactory() {
@Override
public View makeView() {
ImageView myView = new ImageView(getActivity());
myView.setScaleType(ImageView.ScaleType.FIT_XY);
myView.setLayoutParams(new ImageSwitcher.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
return myView;
}
});
dailyWear.setInAnimation(AnimationUtils.loadAnimation(getActivity(), android.R.anim.slide_in_left));
dailyWear.setOutAnimation(AnimationUtils.loadAnimation(getActivity(), android.R.anim.slide_out_right));
final Handler handler = new Handler();
final Runnable r = new Runnable() {
int i=0;
public void run() {
weddingWear.setImageURI(Uri.parse(arr[i));
i++;
if (i >= arr.length()-1)
i = 0;
handler.postDelayed(this, 3000);
}
};
handler.postDelayed(r, 1000);
答案 0 :(得分:0)
你可以做的是首先获取这些图像并将其存储在位图的arraylist中,你可以切换这些图像
private Context mContext;
private int index = 0;
private final int interval = 3000;
private final int DURATION=1500;
public void animate_Images_In_Top_View_After_Every_Three_Seconds(
ImageSwitcher imageSwitcher, final ArrayList<Bitmap> _Images_List) {
android.view.animation.Animation aniIn = AnimationUtils.loadAnimation(mContext,
android.R.anim.fade_in);
aniIn.setDuration(DURATION);
android.view.animation.Animation aniOut = AnimationUtils.loadAnimation(mContext,
android.R.anim.fade_out);
aniOut.setDuration(DURATION);
final ImageSwitcher _ImageSwitcher = imageSwitcher;
_ImageSwitcher.setInAnimation(aniIn);
_ImageSwitcher.setOutAnimation(aniOut);
_ImageSwitcher.setFactory((android.widget.ViewSwitcher.ViewFactory) mContext);
_ImageSwitcher.setImageDrawable(new BitmapDrawable(_Images_List.get(index)));
final Handler handler = new Handler();
Runnable runnable = new Runnable() {
@Override
public void run() {
index++;
index = index % _Images_List.size();
// Log.d("Intro Screen", "Change Image " + index);
_ImageSwitcher.setImageDrawable(new BitmapDrawable(_Images_List.get(index)));
handler.postDelayed(this, interval);
}
};
handler.postDelayed(runnable, interval);
}
我正在使用淡入淡出动画,你可以根据自己的需要设置。
