它傳遞給相機的意圖，但沒有收到點擊圖片，但是當我選擇圖庫選項時，它正在接收所選圖片

Question

我試圖通過意圖從圖庫或相機或文件管理器接收圖片。它傳遞了意圖成功但沒有收到圖片，但在圖庫的情況下，它正在接收選定的圖片。

我的代碼：

private void choosePhotoFromGallery() { 
    Intent pickIntent = new Intent(); 
    pickIntent.setType("image/*"); 
    pickIntent.setAction(Intent.ACTION_GET_CONTENT); 
    Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    String pickTitle = "Take or select a photo"; 
    Intent chooserIntent = Intent.createChooser(pickIntent, pickTitle); 
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { takePhotoIntent }); 
    startActivityForResult(chooserIntent, 1);} 

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (resultCode != Activity.RESULT_OK) { 
     return; 
    } 

    switch (requestCode) { 
     case 1: 
      try { 



InputStream inputStream = getContentResolve().openInputStream(data.getData()); 
       Bitmap bitmap = BitmapFactory.decodeStream(inputStream); 

        imgView.setImageBitmap(scaledBitmap); 

      } catch (Exception e) { 
       Logger.log(e.getMessage()); 
      } 
      break; 

    } 
} 

Answer 1

與您的代碼的問題是這樣的：

data.getData() 

你需要從返回的意圖是這樣獲得額外的：

data.getExtras().get("data"); 

所以你的InputStream應該像 -

InputStream inputStream = getContentResolve().openInputStream(data.getExtras().get("data")); 

更新1：

您還可以修改你的方法，首先創建一個文件，然後將該文件URI傳遞到意圖做這種方式。這可以幫助您避免在以前的方法中可能遇到的設備特定問題。 -

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
// Ensure that there's a camera activity to handle the intent 
if (takePictureIntent.resolveActivity(getPackageManager()) != null) { 
          // Create the File where the photo should go 
     File photoFile = null; 
     try { 
      photoFile = createImageFile(); 
      } catch (IOException ex) { 
      ex.printStackTrace(); 
      } 
     // Continue only if the File was successfully created 
     if (photoFile != null) { 

      takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, 
             Uri.fromFile(photoFile)); 
           startActivityForResult(takePictureIntent, 1734); 
     } 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     if (requestCode==1734 && resultCode==RESULT_OK) 
     { 
      BitmapFactory.Options options = new BitmapFactory.Options(); 
     options.inJustDecodeBounds = true; 
     BitmapFactory.decodeFile(path, options); 
     final int REQUIRED_SIZE = 200; 
     int scale = 1; 
     while (options.outWidth/scale/2 >= REQUIRED_SIZE 
       && options.outHeight/scale/2 >= REQUIRED_SIZE) 
      scale *= 2; 
     options.inSampleSize = scale; 
     options.inJustDecodeBounds = false; 
     Bitmap bitmap = BitmapFactory.decodeFile(path, options); 
    } 
} 

// This is just a method to create a File with current timestamp in name 
private File createImageFile() throws IOException { 
    // Create an image file name 
    File image=null; 
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); 
    String imageFileName = "JPEG_" + timeStamp + "_"; 
    if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) { 
     File storageDir = getExternalFilesDir(null); 
     if (!storageDir.exists()) { 
      storageDir.mkdir(); 
     } 
     image = File.createTempFile(
       imageFileName, /* prefix */ 
       ".jpg",   /* suffix */ 
       storageDir  /* directory */ 
     ); 

     // Save a file: path for use with ACTION_VIEW intents 
     mCurrentPhotoPath = image.getAbsolutePath(); 
    } 
    return image; 

}
