如何使用 android 中的毕加索库将背景图片设置为 activity 布局
How to set background image to activity layout using Picasso Library in android
我正在使用 picasso 库从服务器加载图像。我可以使用 Picasso 将背景图像设置为 ImageView。但我无法使用相同的设置背景图像。我也尝试了不同的方法将图像设置为 activity 布局背景。请帮助我。
我的代码如下:
Picasso.with(getApplicationContext()).load("<a href="https://cms-assets.tutsplus.com/uploads/users/21/posts/19431/featured_image/CodeFeature.jpg" rel="nofollow">https://cms-assets.tutsplus.com/uploads/users/21/posts/19431/featured_image/CodeFeature.jpg</a>").into(new Target() {</p>
@Override
public void onPrepareLoad(Drawable arg0) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Start Loading", Toast.LENGTH_SHORT).show();
}
@Override
public void onBitmapLoaded(Bitmap bitmap, LoadedFrom arg1) {
// TODO Auto-generated method stub
loginLayout.setBackground(new BitmapDrawable(getApplicationContext().getResources(), bitmap));
}
@Override
public void onBitmapFailed(Drawable arg0) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Failed Loading", Toast.LENGTH_SHORT).show();
}
});
尝试使用 setBackgroundDrawable 而不是 setBackground
@Override
public void onBitmapLoaded(Bitmap bitmap, LoadedFrom arg1) {
// TODO Auto-generated method stub
loginLayout.setBackgroundDrawable(new BitmapDrawable(getApplicationContext().getResources(), bitmap));
}
尝试使用 Target
Target target = new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
activityLayout.setBackgroundDrawable(new BitmapDrawable(context.getResources(), bitmap));
}
}
@Override
public void onBitmapFailed(final Drawable errorDrawable) {
}
@Override
public void onPrepareLoad(final Drawable placeHolderDrawable) {
}
};
Picasso.with(getActivity()).load(url).into(target);
