android 在webView里面截圖大概有四種方式,具體內(nèi)容如下
1.獲取到DecorView然后將DecorView轉(zhuǎn)換成bitmap然后寫(xiě)入到文件里面.
View view = getWindow().getDecorView(); Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bitmap); view.draw(canvas); Log.d(TAG,"bitmap--"+bitmap); try { String fileName = Environment.getExternalStorageDirectory().getPath()+"/webview_jietu.jpg"; FileOutputStream fos = new FileOutputStream(fileName); //壓縮bitmap到輸出流中 bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos); fos.close(); Toast.makeText(WebviewFromGetDecorView.this, "截屏成功", Toast.LENGTH_LONG).show(); } catch (Exception e) { Log.e(TAG, e.getMessage()); }finally { if(bitmap!=null) { bitmap.recycle(); } }
