我是Android的新手，目前我正在Android设备app中开发设置动态壁纸。所以，我的问题是如何在任何Android设备中设置gif图像作为壁纸，如动态壁纸。根据我的项目，我有一个imageadapter处理 GIF 图像并将 GIF 图像发送到Imageview，一个活动将该GIF图像显示到imageview，在此活动中我有一个名为<的按钮strong>＆＃34;设置为壁纸＆＃34; ，我正在使用滑动库在imageview中显示 GIF 图片。
ImageAdapter.java
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return mThumbIds[position];
}
public long getItemId(int position) {
return 0;
}
public ImageAdapter(Context c) {
mContext = c;
}
public View getView(final int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null){
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(200, 200));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(3, 3, 3, 3);
imageView.setMaxHeight(300);
imageView.setMaxWidth(300);
imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(mContext, FullScreenImage.class);
intent.putExtra("imageID", mThumbIds[position]);
mContext.startActivity(intent);
}
});
Animation anim = AnimationUtils.loadAnimation(mContext.getApplicationContext(), R.anim.fly);
imageView.setAnimation(anim);
anim.start();
}
else{
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
private Integer[] mThumbIds = {
R.mipmap.h1, R.mipmap.h2,
R.mipmap.h3, R.mipmap.h4,
R.mipmap.h5,R.mipmap.h6,
R.mipmap.h7,R.mipmap.h8,
R.mipmap.h9,R.mipmap.h10,
R.mipmap.h11,R.drawable.gp3,
R.drawable.gp2,R.drawable.gp,
R.drawable.onehalloween
};
}
