在这里,我使用 ScrollView 将整个视图变为位图,因此您可以在这里使用任何其他视图组(如 linerlayout 等)代替滚动视图。
Bitmap map = loadBitmapFromView(getApplicationContext(),scrollView);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
map.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
//you can create a new file name "test.jpg" in sdcard folder.
File f = new File("/sdcard" +"/" + "mainemailpdf.jpg");
f.createNewFile();
//write the bytes in file
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
bArray = bytes.toByteArray();
// remember close de FileOutput
fo.close();
对于 loadBitmapFromView 方法是:
public static Bitmap loadBitmapFromView(Context context, View v) {
Toast.makeText(context,
v.getMeasuredHeight() + "::::::::::::" + v.getMeasuredWidth(),
Toast.LENGTH_LONG).show();
if (v.getMeasuredHeight() > 0) {
v.measure(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
Bitmap b = Bitmap.createBitmap(v.getWidth(), v.getHeight(),
Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.layout(0, 0, v.getWidth(), v.getWidth());
v.draw(c);
return b;
}
return null;
}
我希望它有帮助:)
任何查询让我知道。
