Hello Friends i'm making a app with webview
i want to take screenshot of my activity
Currnetly i'm using this code for capture image
public Bitmap takeScreenshot() {
View rootView = findViewById(android.R.id.content).getRootView();
rootView.setDrawingCacheEnabled(true);
return rootView.getDrawingCache();
}
And This for Save
public void saveBitmap(Bitmap bitmap) {
File imagePath = new File(Environment.getExternalStorageDirectory() + "/screenshot.png");
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
bitmap.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
Log.e("GREC", e.getMessage(), e);
} catch (IOException e) {
Log.e("GREC", e.getMessage(), e);
}
}
It sometime Works and sometime not, i mean ,sometime i can see in gallery screenshot and sometime not
i want to if there is any option to show captured screenshot
Like whhen we press Vol+power button
Main problem is how can i show image when its taken
or know if its taken or not
Thanks in advance
This is a sample approach: save your image -> display result with dialog. And to make it available in Android Gallery, the file path should also be changed:
public void saveBitmap(Bitmap bitmap) {
File path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File imagePath = new File(path, "screenshot.png");//now gallery can see it
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
bitmap.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
displayResult(imagePath.getAbsolutePath())// here you display your result after saving
} catch (FileNotFoundException e) {
Log.e("GREC", e.getMessage(), e);
} catch (IOException e) {
Log.e("GREC", e.getMessage(), e);
}
}
Create another method call displayResult to see the result:
public void displayResult(String imagePath){
//LinearLayOut Setup
LinearLayout linearLayout= new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
//ImageView Setup
ImageView imageView = new ImageView(this);//you need control the context of Imageview
//Diaglog setup
final Dialog dialog = new Dialog(this);//you need control the context of this dialog
dialog.setContentView(imageView);
imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
//Display result
imageView.setImageBitmap(BitmapFactory.decodeFile(imagePath));
dialog.show();
}
Other people have run into issues when trying to get a bitmap from a view's Drawing Cache.
Rather than trying to use the drawing cache, you can instead just get the bitmap directly from the view. Google's DynamicListView example uses the following function to do so.
/** Returns a bitmap showing a screenshot of the view passed in. */
private Bitmap getBitmapFromView(View v) {
Bitmap bitmap = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas (bitmap);
v.draw(canvas);
return bitmap;
}

I have created image view with custom shape using
siyamed/android-shape-imageview
Now i want to save the image on SD card with shape.
How can i achieve this?
As the custom view is just an ImageView, try adding something like this to your buttons on click event to save the image as a bitmap;
ImageView imageViewCustom = (ImageView) findViewById(R.id.image_view_to_save);
try {
imageViewCustom.setDrawingCacheEnabled(true);
FileOutputStream fos = new FileOutputStream(new File(Environment.getExternalStorageDirectory()+"/ACustomShapeFolder/file1234.jpg"));
Bitmap bitmap = imageViewCustom.getDrawingCache();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
Toast.makeText(this, "Error occured", Toast.LENGTH_SHORT).show();
e.printStackTrace();
} catch (IOException e) {
Toast.makeText(this, "Error occured", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
Hope this helps!
Can we get rootview of all the applications on screen in order to take a screenshot?
You need to Xamarinify that code:
private void CaptureScreen()
{
View rootView = Window.DecorView.RootView;
rootView.DrawingCacheEnabled = true;
Bitmap myBitmap = rootView.DrawingCache;
SaveBitmap(myBitmap); // ...........
}
private void SaveBitmap(Bitmap bitmap)
{
File dir = new Java.IO.File(Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryPictures).Path);
if (!dir.Exists()) dir.Mkdirs();
System.IO.Stream fos = new System.IO.FileStream(dir.Path + #"/pic.jpg", System.IO.FileMode.Create);
try
{
bitmap.Compress(
Android.Graphics.Bitmap.CompressFormat.Png, 100, fos);
fos.Flush();
fos.Close();
}
catch (FileNotFoundException e)
{
}
catch (IOException e)
{
}
}
This is far from production ready code but gives you the idea
Try this for get rootview -
getWindow().getDecorView().findViewById(android.R.id.content)
Hope this helps you!!
can someone help me?
I want to take a screenshot and post this to the facebook wall (with a message)!
I have read several topics and forums but i dont find something that worked for me!
I already have the facebook SDK!
Thanks a lot!
capture images of view using this way.
View v = view.getRootView();
v.setDrawingCacheEnabled(true);
Bitmap b = v.getDrawingCache();
String extr = Environment.getExternalStorageDirectory().toString();
File myPath = new File(extr, "yourImageName.jpg");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(myPath);
b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
here v is root layout and than post photo in facebook using SDK 3.5.
like this way
private SimpleFacebook mSimpleFacebook;
mSimpleFacebook = SimpleFacebook.getInstance(this);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(photoPath, options);
// create Photo instace and add some properties
Photo photo = new Photo(bitmap);
photo.addDescription("Screenshot from sample application");
photo.addPlace("110619208966868");
// publish
mSimpleFacebook.publish(photo, new OnPublishListener()
{
#Override
public void onFail(String reason)
{
mProgress.hide();
// insure that you are logged in before publishing
Log.w(TAG, "Failed to publish");
}
#Override
public void onException(Throwable throwable)
{
mProgress.hide();
Log.e(TAG, "Bad thing happened", throwable);
}
#Override
public void onThinking()
{
// show progress bar or something to the user while publishing
mProgress = ProgressDialog.show(this, "Thinking",
"Waiting for Facebook", true);
}
#Override
public void onComplete(String id)
{
mProgress.hide();
toast("Published successfully. The new image id = " + id);
}
});
Here is my code to take screen shot and save it in gallery.tried by debugging here screen is captured but not saving to gallery.
#Override
public void onClick(View v) {
Bitmap bitmap = takeScreenshot();
saveBitmap(bitmap);
}
making screenshot
protected Bitmap takeScreenshot() {
// TODO Auto-generated method stub
View rootView = findViewById(android.R.id.content).getRootView();
rootView.setDrawingCacheEnabled(true);
Toast.makeText(getApplicationContext(), "Screen captured", Toast.LENGTH_LONG).show();
return rootView.getDrawingCache();
}
Saving screen here
protected void saveBitmap(Bitmap bitmap) {
// TODO Auto-generated method stub
File imagePath = new File(Environment.getExternalStorageDirectory()
+ "/screenshot.png");
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
bitmap.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
Toast.makeText(getApplicationContext(), "Screen saved", Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {
Log.e("GREC", e.getMessage(), e);
} catch (IOException e) {
Log.e("GREC", e.getMessage(), e);
}
}
Run your code in device please, it may be the problem of emulator, because emulator dont have physical SD Card.
First off i am writing a root app so root permissions are no issue. I've searched and searched and found a lot of code that never worked for me here is what i've pieced together so far and sorta works. When i say sorta i mean it makes an image on my /sdcard/test.png however the file is 0 bytes and obviously can't be viewed.
public class ScreenShot extends Activity{
View content;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.blank);
content = findViewById(R.id.blankview);
getScreen();
}
private void getScreen(){
Bitmap bitmap = content.getDrawingCache();
File file = new File("/sdcard/test.png");
try
{
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, ostream);
ostream.close();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
Any help on how i can take a screen shot in android via code would be greatly appreciated thank you!
===EDIT===
The following is everything i'm using the image is made on my sdcard and is no longer 0bytes but the entire thing is black there is nothing on it. I've bound the activity to my search button so when i'm some where on my phone i long press search and it is supposed to take a screen shot but i just get a black image? Everything is set transparent so i'd think it should grab whatever is on the screen but i just keep getting black
Manifest
<activity android:name=".extras.ScreenShot"
android:theme="#android:style/Theme.Translucent.NoTitleBar"
android:noHistory="true" >
<intent-filter>
<action android:name="android.intent.action.SEARCH_LONG_PRESS" />
<category android:name="android.intent.category.DEFAULT" />

Screenshot class
public class ScreenShot extends Activity{
View content;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.screenshot);
content = findViewById(R.id.screenRoot);
ViewTreeObserver vto = content.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
content.getViewTreeObserver().removeGlobalOnLayoutListener(this);
getScreen();
}
});
}
private void getScreen(){
View view = content;
View v = view.getRootView();
v.setDrawingCacheEnabled(true);
Bitmap b = v.getDrawingCache();
String extr = Environment.getExternalStorageDirectory().toString();
File myPath = new File(extr, "test.jpg");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(myPath);
b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
}catch (FileNotFoundException e) {
// TODO Auto-generated catch block

Here you go...I used this:
View v = view.getRootView();
v.setDrawingCacheEnabled(true);
Bitmap b = v.getDrawingCache();
String extr = Environment.getExternalStorageDirectory().toString();
File myPath = new File(extr, getString(R.string.free_tiket)+".jpg");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(myPath);
b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
MediaStore.Images.Media.insertImage( getContentResolver(), b,
"Screen", "screen");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
v iz root layout...just to point ;)))
For the next reader of this question-
The very simple way to do this by drawing your view to canvas-
pass your main layout reference to this method-
Bitmap file = save(layout);
Bitmap save(View v)
{
Bitmap b = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.draw(c);
return b;
}
I think you have to wait until the layout is drawn completely..Use ViewTreeObserver to get a call back when layout is drawn completely..
On your onCreate add this code..Only call getScreen from inside onGlobalLayout()..
ViewTreeObserver vto = content.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
content.getViewTreeObserver().removeGlobalOnLayoutListener(this);
getScreen();
}
});
I asked a somewhat similiar question once..Please see my question which explains the way to take screenshot in android..Hope this helps
public class MainActivity extends Activity
{
Button btn;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.btn);
btn.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
// TODO Auto-generated method stub
Bitmap bitmap = takeScreenshot();
saveBitmap(bitmap);
}
});
}
public Bitmap takeScreenshot()
{
View rootView = findViewById(android.R.id.content).getRootView();
rootView.setDrawingCacheEnabled(true);
return rootView.getDrawingCache();
}
public void saveBitmap(Bitmap bitmap)
{
File imagePath = new File(Environment.getExternalStorageDirectory() + "/screenshot.png");
FileOutputStream fos;
try
{
fos = new FileOutputStream(imagePath);
bitmap.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
}
catch (FileNotFoundException e)
{
Log.e("GREC", e.getMessage(), e);
}
catch (IOException e)
{
Log.e("GREC", e.getMessage(), e);
}
}
}
don't forgot to give write external storage permission!
You Take Screen Shot Like this........
View view = findViewById(R.id.rellayout);
view.getRootView();
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state))
{
File picDir = new File(Environment.getExternalStorageDirectory()+ "/name");
if (!picDir.exists())
{
picDir.mkdir();
}
view.setDrawingCacheEnabled(true);
view.buildDrawingCache(true);
Bitmap bitmap = view.getDrawingCache();
// Date date = new Date();
String fileName = "mylove" + ".jpg";
File picFile = new File(picDir + "/" + fileName);
try
{
picFile.createNewFile();
FileOutputStream picOut = new FileOutputStream(picFile);
bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), (int)(bitmap.getHeight()/1.2));//Optional
boolean saved = bitmap.compress(CompressFormat.JPEG, 100, picOut);
if (saved)
{
Toast.makeText(getApplicationContext(), "Image saved to your device Pictures "+ "directory!", Toast.LENGTH_SHORT).show();
} else
{
//Error
}
picOut.close();
}
catch (Exception e)
{
e.printStackTrace();
}
view.destroyDrawingCache();
} else {
}
