從畫廊和相機拍攝照片android

Question

我需要從畫廊和相機拍照。就像詢問相機和畫廊的選項。目前，我能夠捕捉圖像並存儲在圖像視圖中。但不能從畫廊

這是我的代碼採摘後再次從畫廊正在採取回相機上傳，

@BindView（R.id.selImage）按鈕selImage; @Nullable @BindView（R.id.uProfileImage）ImageView uProfileImage;私人Uri fileUri;

selImage.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      captureImage(); 
     } 
    }); 


private void captureImage() { 
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); 

    Log.e("FileURI", "captureImage: "+fileUri); 

    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); 

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



private void previewCapturedImage() { 
    try { 
     FileOutputStream out = null; 
     uProfileImage.setVisibility(View.VISIBLE); 

     // bimatp factory 
     BitmapFactory.Options options = new BitmapFactory.Options(); 

     // downsizing image as it throws OutOfMemory Exception for larger 
     // images 
     options.inSampleSize = 8; 

     final Bitmap bitmap = BitmapFactory.decodeFile(fileUri.getPath(), 
       options); 
     try { 

      out = new FileOutputStream(fileUri.getPath()); 
      bitmap.compress(Bitmap.CompressFormat.JPEG, 100 , out); 
     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } 
     Log.e("Image", "previewCapturedImage: fileUri.getPath() "+fileUri.getPath()); 

     uProfileImage.setImageBitmap(getRoundedShape(bitmap)); 
    } catch (NullPointerException e) { 
     e.printStackTrace(); 
    } 
} 

保護無效onActivityResult（INT requestCode，INT發送resultCode， 意圖數據）

{

if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) { 
     if (resultCode == RESULT_OK) { 
      // successfully captured the image 
      // display it in image view 
      previewCapturedImage(); 


     } else if (resultCode == RESULT_CANCELED) { 
      // user cancelled Image capture 
      Toast.makeText(getApplicationContext(), 
        "User cancelled image capture", Toast.LENGTH_SHORT) 
        .show(); 
     } else { 
      // failed to capture image 
      Toast.makeText(getApplicationContext(), 
        "Sorry! Failed to capture image", Toast.LENGTH_SHORT) 
        .show(); 
     } 
    } 
} 

請建議我如何從庫中添加圖像，並在我的代碼存儲

Answer 1

後你可以試試這個代碼。

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     if(resultCode==RESULT_OK){ 
      if(requestCode==1){ 
       onSelectFromGalleryResult(data); 
      }else if(requestCode==2){ 
       onCaptureImageResult(data); 
      } 
     } 
    } 

//OnClick For Gallary Button 
public void pickFromGal(View view){ 
     Intent getIntent = new Intent(
       Intent.ACTION_PICK, 
       android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI); 
     getIntent.setType("image/*"); 
     startActivityForResult(getIntent, 1); 
    } 
//OnClick Camera Button 
    public void pickFromCam(View view){ 
     Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     startActivityForResult(intent, 2); 
    } 



    private void onCaptureImageResult(Intent data) { 
     Bitmap thumbnail = (Bitmap) data.getExtras().get("data"); 
     imageView.setImageBitmap(thumbnail); 

    } 
    private void onSelectFromGalleryResult(Intent data) { 
     Bitmap bm=null; 
     if (data != null) { 
      try { 
       Uri chosenImageUri = data.getData(); 
       bm = MediaStore.Images.Media.getBitmap(getContentResolver(), chosenImageUri);     
       imageView.setImageBitmap(bm); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 
    } 

Answer 2

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
      File filePhoto = new File(Environment.getExternalStorageDirectory(), "Pic.jpg"); 
      filePhoto.delete(); 
      imageUri = Uri.fromFile(filePhoto); 
      intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); 
      startActivityForResult(intent, REQUEST_CODE); 

對於GALLARY

Intent galleryIntent = new Intent(Intent.ACTION_PICK, 
           MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
         startActivityForResult(galleryIntent, RESULT_LOAD_IMG); 

if (requestCode == this.REQUEST_CODE) { 
     Uri selectedImage = imageUri ; 
     this.getContentResolver().notifyChange(selectedImage, null); 
     ContentResolver cr = this.getContentResolver(); 
     Bitmap bitmap; 
     try { 
      bitmap = android.provider.MediaStore.Images.Media 
        .getBitmap(cr,imageUri); 
      imageView.setImageBitmap(bitmap); 
     } catch (Exception e) { 
      e.printStackTrace(); 
      Toast.makeText(this, "Camera is closed", Toast.LENGTH_SHORT).show(); 
     } 
    } else{ 

     try { 
      final Uri imageUri = data.getData(); 
      final InputStream imageStream = getContentResolver().openInputStream(imageUri); 
      bitmap = BitmapFactory.decodeStream(imageStream); 
      imageView.setImageBitmap(bitmap); 
     } catch (Exception e) { 
      e.printStackTrace(); 
      // Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG).show(); 
     } 
    }

這裏完整的源代碼從圖庫中獲取圖庫和從卡馬拉捕獲圖像。這裏選擇裁剪圖像也是可用的.happy編碼使用selectImageOption（）方法，即使你想要的按鈕或圖像點擊。

private static final int CAMERA_CODE = 101, GALLERY_CODE = 201, CROPING_CODE = 301;
