解决方案，到目前为止，我已经尝试过！
Solution, I have tried so far!
public Bitmap takeScreenshot() {
View rootView = getWindow().getDecorView().findViewById(R.id.scrollView); //Instead of ScrollView I have taken Main view to but no luck
rootView.setDrawingCacheEnabled(true);
return rootView.getDrawingCache();
}
public Bitmap takeScreenshot() {
View rootView = getWindow().getDecorView().findViewById(R.id.constraintLayout); //Here also I have taken ScrollView too.
Bitmap b = Bitmap.createBitmap(rootView.getWidth() , rootView.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
rootView.layout(0, 0, rootView.getLayoutParams().width, rootView.getLayoutParams().height);
rootView.draw(c);
return b;
}
public Bitmap takeScreenshot() {
ScrollView iv = (ScrollView) findViewById(R.id.scrollView);
Bitmap bitmap = Bitmap.createBitmap(
iv.getChildAt(0).getWidth(),
iv.getChildAt(0).getHeight(),
Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(bitmap);
iv.getChildAt(0).draw(c);
return bitmap;
}
在上述所有方法中，我都有黑色"背景屏幕截图.除了这些以外，还有其他解决方案吗?或者在截取屏幕截图时我犯了任何错误?
In all the above method, I am having "Black" background screenshot. Apart from these do anyone have other solutions or am I making any mistakes in taking Screenshot?
推荐答案
我希望这对您有用..源此处
I hope this is work for you.. source here
Bitmap bitmap = getBitmapFromView(scrollview, scrollview.getChildAt(0).getHeight(), scrollview.getChildAt(0).getWidth());
//create bitmap from the ScrollView
private Bitmap getBitmapFromView(View view, int height, int width) {
Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
Drawable bgDrawable = view.getBackground();
if (bgDrawable != null)
bgDrawable.draw(canvas);
else
canvas.drawColor(Color.WHITE);
view.draw(canvas);
return bitmap;
}
