我有一个视图是从一个布局充气:
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View tagView = inflater.inflate(R.layout.activity_main, null);
TextView name = (TextView) tagView.findViewById(R.id.textView1);
name.setText("hello");
现在我想把膨胀的视图转换成位图
我该怎么办?
最佳答案
您可以按以下步骤完成:
//first, View preparation
LayoutInflater inflater =
(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View tagView = inflater.inflate(R.layout.activity_main, null);
TextView name = (TextView) tagView.findViewById(R.id.textView1);
name.setText("hello");
//second, set the width and height of inflated view
tagView.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
tagView.layout(0, 0, tagView.getMeasuredWidth(), tagView.getMeasuredHeight());
//third, finally conversion
final Bitmap bitmap = Bitmap.createBitmap(tagView.getMeasuredWidth(),
tagView.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
tagView.draw(canvas);
最后,你得到了你膨胀的
bitmap
的tagView
。
