Launch and install the camera for Android

I'm trying to upload a camera to take a picture from my Android application,

my Photos.java

private Uri imageUri; public void takePhoto(View view) { Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg"); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo)); imageUri = Uri.fromFile(photo); startActivityForResult(intent, TAKE_PICTURE); } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode) { case TAKE_PICTURE: if (resultCode == Activity.RESULT_OK) { Uri selectedImage = imageUri; getContentResolver().notifyChange(selectedImage, null); ImageView imageView = (ImageView) findViewById(R.id.ImageView); ContentResolver cr = getContentResolver(); Bitmap bitmap; try { bitmap = android.provider.MediaStore.Images.Media .getBitmap(cr, selectedImage); imageView.setImageBitmap(bitmap); Toast.makeText(this, selectedImage.toString(), Toast.LENGTH_LONG).show(); } catch (Exception e) { Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT) .show(); Log.e("Camera", e.toString()); } } }

and it works great. But his section of the layout, to name this intention, with which I struggle.

I created a button to load the camera

 <Button android:id="@+id/takePhoto" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="41dp" android:onClick="takePhoto" android:text="@string/Photos_Button1" />

but now I need to have a section to show the image I took. How to do it?

Try to try ...

NOTE. Only for Android API 8 // 2.2 or higher

 public class PhotoActivity extends Activity { /** The Constant PICK_IMAGE. */ private static final int PICK_IMAGE = 0; /** The Constant PICK_IMAGE_FROM_GALLERY. */ private static final int PICK_IMAGE_FROM_GALLERY = 1; /** The btn cancel. */ private Button btnPhotoCamera,btnPhotoGallery,btnCancel; /** The img view. */ private ImageView imgView; /** The u. */ private Uri u; /* (non-Javadoc) * @see android.app.Activity#onCreate(android.os.Bundle) */ @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity_photo_options); imgView=(ImageView)findViewById(R.id.imgDisplayImage); btnPhotoCamera=(Button)findViewById(R.id.btnPhotoCamera); btnPhotoGallery=(Button)findViewById(R.id.btnPhotoGallery); btnCancel=(Button)findViewById(R.id.btnCancel); btnPhotoCamera.setOnClickListener(new OnClickListener() { public void onClick(View v) { Intent camera=new Intent(); camera.setAction(MediaStore.ACTION_IMAGE_CAPTURE); camera.putExtra("crop", "true"); File f=Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES); u = Uri.fromFile(new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),"myFile.jpg")); camera.putExtra(MediaStore.EXTRA_OUTPUT, u); startActivityForResult(camera, PICK_IMAGE); } }); btnPhotoGallery.setOnClickListener(new OnClickListener() { public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK); intent.setType("image/*"); startActivityForResult(intent, PICK_IMAGE_FROM_GALLERY); } }); btnCancel.setOnClickListener(new OnClickListener() { public void onClick(View v) { Intent goStartUp=new Intent(PhotoActivity.this, StartUpActivity.class); goStartUp.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(goStartUp); finish(); } }); } /* (non-Javadoc) * @see android.app.Activity#onActivityResult(int, int, android.content.Intent) */ @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub if (resultCode==RESULT_OK ) { if(requestCode == PICK_IMAGE) { InputStream is=null; try { is = this.getContentResolver().openInputStream(u); } catch (FileNotFoundException e) { e.printStackTrace(); } Bitmap bmp=BitmapFactory.decodeStream(is); imgView.setImageBitmap(bmp); Log.i("Inside", "PICK_IMAGE"); } if (requestCode == PICK_IMAGE_FROM_GALLERY) { Uri selectedImage = data.getData(); String[] filePathColumn = { MediaStore.Images.Media.DATA }; Log.d("data",filePathColumn[0]); Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null); cursor.moveToFirst(); int columnIndex = cursor.getColumnIndex(filePathColumn[0]); String picturePath = cursor.getString(columnIndex); cursor.close(); imgView.setImageBitmap(BitmapFactory.decodeFile(picturePath)); Log.i("Inside", "PICK_IMAGE_FROM_GALLERY"); } } } }

XML file: -

 <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#f0f0f0"> <TextView android:id="@+id/lblSelectOptions" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="20dp" android:layout_marginTop="20dp" android:text="@string/two_options" android:textAppearance="?android:attr/textAppearanceLarge" android:textColor="#ff0000"/> <Button android:id="@+id/btnPhotoCamera" android:layout_width="75dp" android:layout_height="wrap_content" android:layout_below="@+id/lblSelectOptions" android:layout_centerHorizontal="true" android:layout_marginTop="10dp" android:text="@string/camera"/> <Button android:id="@+id/btnPhotoGallery" android:layout_width="75dp" android:layout_height="wrap_content" android:layout_below="@+id/btnPhotoCamera" android:layout_centerHorizontal="true" android:layout_marginTop="10dp" android:text="@string/gallery"/> <Button android:id="@+id/btnCancel" android:layout_width="120dp" android:layout_height="wrap_content" android:layout_below="@+id/btnPhotoGallery" android:layout_centerHorizontal="true" android:layout_marginTop="19dp" android:text="@string/cancel"/> <TextView android:id="@+id/lblDisplayImage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/btnCancel" android:layout_centerHorizontal="true" android:layout_marginTop="10dp" android:text="@string/below_this_text_image_will_be_displayed" android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="#000000" android:textSize="13dp"/> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_below="@+id/lblDisplayImage" android:layout_centerInParent="true" android:layout_marginTop="10dp" android:gravity="bottom"> <!-- <ScrollView android:layout_width="match_parent" android:layout_height="match_parent" > --> <ImageView android:id="@+id/imgDisplayImage" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@+id/lblDisplayImage" android:layout_centerInParent="true" android:contentDescription="@string/area_where_image_is_to_be_displayed" /> <!-- </ScrollView> --> </RelativeLayout> </RelativeLayout>

Also modify the Android manifest file to suit your needs as follows: -

 <manifest.... <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="21" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.RECORD_VIDEO" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-feature android:name="android.hardware.camera" android:required="false" /> <application.... .......... </application> </manifest>

I used

  android:onClick="takePhoto"

however it was nowhere in my java, I fabricated "takePhoto"
