Android open camera from button

Question

I hope this isn\'t a duplicate question but I am making an app that I want a button to open the camera app (the default android camera separately). How do I got about doing

Answer 1

You can create a camera intent and call it as startActivityForResult(intent).

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

   // start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

Answer 2

For me this worked perfectly fine .

 Intent intent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 startActivity(intent);

and add this permission to mainfest file:

<uses-permission android:name="android.permission.CAMERA">

It opens the camera,after capturing the image it saves the image to gallery with a new image set.

Answer 3

public class camera_act extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera_act);
         ImageView imageView = findViewById(R.id.image);
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent,90);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode,resultCode,data);
       Bitmap bitmap = data.getExtras.get("imageKey");
       imageView.setBitmapImage(bitmap);
            
        }
    }
}

Answer 4

I know it is a bit late of a reply but you can use the below syntax as it worked with me just fine

Camera=(Button)findViewById(R.id.CameraID);
Camera.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent Intent3=new   Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA);
            startActivity(Intent3); 
        }
    });

Answer 5

You are correct about the action used in Intent but it's not the only thing you have to do. You'll also have to add

startActivityForResult(intent, YOUR_REQUEST_CODE);

To get it all done and retrieve the actual picture you could check the following thread.

Answer 6

 Button b = (Button)findViewById(R.id.Button01);

    b.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
             Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
             startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
        }
    });
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_PIC_REQUEST) {
          Bitmap image = (Bitmap) data.getExtras().get("data");
          ImageView imageview = (ImageView) findViewById(R.id.ImageView01); //sets imageview as the bitmap
          imageview.setImageBitmap(image);
    }
}
