[英]how to get the path of the image(.png) file that is stored in assets folder in android
[英]How to convert HTML files (stored in assets) to image in android?
我正在嘗試將存儲為資產的html文件轉換為圖像,以便我可以共享它們。 我嘗試了以下代碼:
Picture picture = webView.capturePicture();
Bitmap b = Bitmap.createBitmap(
picture.getWidth(), picture.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
picture.draw(c);
FileOutputStream fos = null;
try {
fos = new FileOutputStream( Environment.getExternalStorageDirectory().toString() +"/temp.jpg");
if ( fos != null ) {
b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
Toast.makeText(SyllabusPage_NW.this, "created", Toast.LENGTH_SHORT).show();
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(Environment.getExternalStorageDirectory().toString() + "/temp.jpg");
sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));
fos.close();
}
}
catch( Exception e ) {
Toast.makeText(SyllabusPage_NW.this, "Error", Toast.LENGTH_SHORT).show();
}
附加了結果,並附加了預期結果。 Web視圖僅捕獲html頁面的第一部分。 我想知道如何捕獲整個html頁面而不只是第一部分?
對於API Lollipop及更高版本,應啟用緩慢繪制:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
WebView.enableSlowWholeDocumentDraw();
}
然后通過調試檢查圖片的高度是否正確。
如果不是,首先測量Webview,然后進行布局。
webView.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
webView.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
webView.buildDrawingCache(true);
Bitmap b = Bitmap.createBitmap(webView.getDrawingCache());
webView.setDrawingCacheEnabled(false);
