android從圖庫中挑選圖片

Question

我想從圖庫中創建圖片選擇器。我使用代碼

intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
startActivityForResult(intent, TFRequestCodes.GALLERY); 

我的問題是，在這個活動和視頻文件顯示。有沒有辦法過濾顯示的文件，以便在此活動中不顯示視頻文件？

Answer 1

絕對。試試這個：

Intent intent = new Intent(); 
intent.setType("image/*"); 
intent.setAction(Intent.ACTION_GET_CONTENT); 
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE); 

也不要忘記創建不斷PICK_IMAGE，這樣你就可以識別，當用戶從圖片庫活動回來：

public static final int PICK_IMAGE = 1; 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) 
{ 
    if (requestCode == PICK_IMAGE) { 
     //TODO: action 
    } 
} 

這就是我如何調用圖片庫。把它放進去，看看它是否適合你。

編輯：

這將帶來文檔應用程序。爲了讓用戶使用起來也有可能被安裝任何應用程序畫廊：

Intent getIntent = new Intent(Intent.ACTION_GET_CONTENT); 
    getIntent.setType("image/*"); 

    Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
    pickIntent.setType("image/*"); 

    Intent chooserIntent = Intent.createChooser(getIntent, "Select Image"); 
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] {pickIntent}); 

    startActivityForResult(chooserIntent, PICK_IMAGE); 

Answer 2

有時候，你不能從你選擇的圖片文件。 這是因爲選擇的來自Google+，Drive，Dropbox或任何其他提供商。

最好的解決方案是讓系統通過Intent.ACTION_GET_CONTENT選擇一個內容，並獲得一個內容提供者的結果。

您可以按照下面的代碼或看看我的updated gist。

public void pickImage() { 
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
    intent.setType("image/*"); 
    startActivityForResult(intent, PICK_PHOTO_FOR_AVATAR); 
} 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    if (requestCode == PICK_PHOTO_FOR_AVATAR && resultCode == Activity.RESULT_OK) { 
     if (data == null) { 
      //Display an error 
      return; 
     } 
     InputStream inputStream = context.getContentResolver().openInputStream(data.getData()); 
     //Now you can do whatever you want with your inpustream, save it as file, upload to a server, decode a bitmap... 
    } 
}

如果你只是在尋找圖片和多項選擇。

這有助於future.I個人感覺好極了使用MultipleImagePick。

Answer 4

public void FromCamera() { 

    Log.i("camera", "startCameraActivity()"); 
    File file = new File(path); 
    Uri outputFileUri = Uri.fromFile(file); 
    Intent intent = new Intent(
      android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 
    startActivityForResult(intent, 1); 

} 

public void FromCard() { 
    Intent i = new Intent(Intent.ACTION_PICK, 
      android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
    startActivityForResult(i, 2); 
} 

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 

    super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == 2 && resultCode == RESULT_OK 
      && null != data) { 

     Uri selectedImage = data.getData(); 
     String[] filePathColumn = { MediaStore.Images.Media.DATA }; 

     Cursor cursor = getContentResolver().query(selectedImage, 
       filePathColumn, null, null, null); 
     cursor.moveToFirst(); 

     int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
     String picturePath = cursor.getString(columnIndex); 
     cursor.close(); 

     bitmap = BitmapFactory.decodeFile(picturePath); 
     image.setImageBitmap(bitmap); 

     if (bitmap != null) { 
      ImageView rotate = (ImageView) findViewById(R.id.rotate); 

     } 

    } else { 

     Log.i("SonaSys", "resultCode: " + resultCode); 
     switch (resultCode) { 
     case 0: 
      Log.i("SonaSys", "User cancelled"); 
      break; 
     case -1: 
      onPhotoTaken(); 
      break; 

     } 

    } 

} 

protected void onPhotoTaken() { 
    // Log message 
    Log.i("SonaSys", "onPhotoTaken"); 
    taken = true; 
    imgCapFlag = true; 
    BitmapFactory.Options options = new BitmapFactory.Options(); 
    options.inSampleSize = 4; 
    bitmap = BitmapFactory.decodeFile(path, options); 
    image.setImageBitmap(bitmap); 


} 

Answer 5

U可以比這做的答案很容易：

Uri Selected_Image_Uri = data.getData(); 
ImageView imageView = (ImageView) findViewById(R.id.loadedimg); 
imageView.setImageURI(Selected_Image_Uri); 

Answer 6

您可以使用此方法從圖庫中選擇圖片。只會顯示圖像。

public void pickImage() { 
    Intent intent = new Intent(Intent.ACTION_PICK, 
      MediaStore.Images.Media.INTERNAL_CONTENT_URI); 
    intent.setType("image/*"); 
    intent.putExtra("crop", "true"); 
    intent.putExtra("scale", true); 
    intent.putExtra("outputX", 256); 
    intent.putExtra("outputY", 256); 
    intent.putExtra("aspectX", 1); 
    intent.putExtra("aspectY", 1); 
    intent.putExtra("return-data", true); 
    startActivityForResult(intent, 1); 
} 

，並覆蓋onActivityResult作爲

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (resultCode != RESULT_OK) { 
      return; 
     } 
     if (requestCode == 1) { 
      final Bundle extras = data.getExtras(); 
      if (extras != null) { 
       //Get image 
       Bitmap newProfilePic = extras.getParcelable("data"); 
      } 
     } 
    }
