I have created an app with a button and wrote onClickListener for that button. I have tried several sample code examples and none of them worked. They all bring up the Android camera app and don't take photographs. I want some code which I can put in my onClickListener so when I press the button on the screen, a picture will be taken.
How can I make the camera take a picture when I press a button in an Android activity?
Look at following demo code.
Here is your XML file for UI,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="@+id/btnCapture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Camera" />
</LinearLayout>
And here is your Java class file,
public class CameraDemoActivity extends Activity {
int TAKE_PHOTO_CODE = 0;
public static int count = 0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Here, we are making a folder named picFolder to store
// pics taken by the camera using this application.
final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";
File newdir = new File(dir);
newdir.mkdirs();
Button capture = (Button) findViewById(R.id.btnCapture);
capture.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Here, the counter will be incremented each time, and the
// picture taken by camera will be stored as 1.jpg,2.jpg
// and likewise.
count++;
String file = dir+count+".jpg";
File newfile = new File(file);
try {
newfile.createNewFile();
}
catch (IOException e)
{
}
Uri outputFileUri = Uri.fromFile(newfile);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
Log.d("CameraDemo", "Pic saved");
}
}
}
Note:
Specify the following permissions in your manifest file,
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
click on capture button to capture the image –
Cilicia Camera as mentioned in my answer –
Cilicia picFolder but android doesn't know about newly created file.so you need to send broadcast to update it.have a look at http://stackoverflow.com/questions/8667623/updating-gallery-after-taking-pictures-gallery-not-showing-all-the-pictures-andr –
Cilicia http://developer.android.com/training/camera/photobasics.html –
Cilicia camera.performclick(); can open camera only. it will not take picture directly. for that,user has to interact. –
Cilicia startActivityForResult is deprecated so consider using the new way, can be reference here : #62671606 –
Prostomium There are two ways to take a photo:
1 - Using an Intent to make a photo
2 - Using the camera API
I think you should use the second way and there is a sample code here for two of them.
You can use Magical Take Photo library.
1. try with compile in gradle
compile 'com.frosquivel:magicaltakephoto:1.0'
2. You need this permission in your manifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA"/>
3. instance the class like this
// "this" is the current activity param
MagicalTakePhoto magicalTakePhoto = new MagicalTakePhoto(this,ANY_INTEGER_0_TO_4000_FOR_QUALITY);
4. if you need to take picture use the method
magicalTakePhoto.takePhoto("my_photo_name");
5. if you need to select picture in device, try with the method:
magicalTakePhoto.selectedPicture("my_header_name");
6. You need to override the method onActivityResult of the activity or fragment like this:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
magicalTakePhoto.resultPhoto(requestCode, resultCode, data);
// example to get photo
// imageView.setImageBitmap(magicalTakePhoto.getMyPhoto());
}
Note: Only with this Library you can take and select picture in the device, this use a min API 15.
For those who came here looking for a way to take pictures/photos programmatically using both Android's Camera and Camera2 API, take a look at the open source sample provided by Google itself here.
Take and store image in desired folder
//Global Variables
private static final int CAMERA_IMAGE_REQUEST = 101;
private String imageName;
Take picture function
public void captureImage() {
// Creating folders for Image
String imageFolderPath = Environment.getExternalStorageDirectory().toString()
+ "/AutoFare";
File imagesFolder = new File(imageFolderPath);
imagesFolder.mkdirs();
// Generating file name
imageName = new Date().toString() + ".png";
// Creating image here
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(imageFolderPath, imageName)));
startActivityForResult(takePictureIntent,
CAMERA_IMAGE_REQUEST);
}
Broadcast new image added otherwise pic will not be visible in image gallery
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && requestCode == CAMERA_IMAGE_REQUEST) {
Toast.makeText(getActivity(), "Success",
Toast.LENGTH_SHORT).show();
//Scan new image added
MediaScannerConnection.scanFile(getActivity(), new String[]{new File(Environment.getExternalStorageDirectory()
+ "/AutoFare/" + imageName).getPath()}, new String[]{"image/png"}, null);
// Work in few phones
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getActivity().sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse(Environment.getExternalStorageDirectory()
+ "/AutoFare/" + imageName)));
} else {
getActivity().sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse(Environment.getExternalStorageDirectory()
+ "/AutoFare/" + imageName)));
}
} else {
Toast.makeText(getActivity(), "Take Picture Failed or canceled",
Toast.LENGTH_SHORT).show();
}
}
Permissions
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
The following is a simple way to open the camera:
private void startCamera() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI.getPath());
startActivityForResult(intent, 1);
}
Intent takePhoto = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(takePhoto, CAMERA_PIC_REQUEST)
and set
CAMERA_PIC_REQUEST= 1 or 0
