How to take snapshot for html page webkit on android nativelly?
It's simple...view my solution comprovated on one project for
orthodontics: 1) You create one WebView widget on main Activity class file
on onCreate method with url for HTML5 page; 2) Create one method for
printing content(printHTMLSnapshot); 3) Bind the method for printing with
one event click for example one Button widget including on your Button on
main_layout.xml that: android:onClick="printHTMLSnapshot" after element
android:id on Button tag. 4) Complete all code on method and path for save
image and task concluded for tests;
WebView wv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_archade_tooth);
String url ="file:///android_asset/xxxxxx.html";
wv=(WebView) findViewById(R.id.webView1);
wv.getSettings().setJavaScriptEnabled(true);
wv.getSettings().setPluginState(PluginState.ON);
wv.loadUrl(url);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.archade_tooth, menu);
return true;
}
public void printHTMLSnapshot(View view) {
Log.e("MSG",">>> Begin printing...>>>");
Picture picture = wv.capturePicture();
Bitmap b = Bitmap.createBitmap(picture.getWidth(),
picture.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas( b );
picture.draw( c );
ByteArrayOutputStream stream = null;
byte[] byteArchadeImage = null;
Intent i = getIntent();
// ************ Patient is a bean that save stream for image file on
some local
Patient patient = (Patient) i.getSerializableExtra("patient");
try {
stream = new ByteArrayOutputStream();
if ( stream != null )
{
b.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byteArchadeImage = stream.toByteArray();
if (null!=patient) {
patient.setArchadeImage(byteArchadeImage);
}
stream.flush();
stream.close();
}
}
catch( Exception e )
{
Log.e("MSG", e.getLocalizedMessage());
} finally {
i.setClass(getBaseContext(), ServicesArchadeToothActivity.class);
i.putExtra("patient", patient);
startActivity(i);
}
Log.e("MSG",">>> Ended printing...>>>");
}
