相機停止，位圖爲空

新的android，我有一個按鈕來打開畫廊選擇一張圖片，並將其顯示到一個ImageView，它工作正常，另一個按鈕打開相機使用意圖，我可以打開相機拍攝一張圖片，但點擊保存圖片後，應用程序崩潰。拍攝的圖像保存在正確的文件夾中。當debbugin的應用程序的錯誤拋出它的線：相機停止，位圖爲空

filePath = data.getData();

和位圖顯示爲空。我已經添加了權限，我已經閱讀了很多關於此的帖子，但仍然無法弄清楚問題所在。任何幫助表示讚賞。這是代碼。

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    if(requestCode == CAM_REQUEST && resultCode == Activity.RESULT_OK){ 
     Toast.makeText(TerminosYC.this.getActivity(), "si hay foto", Toast.LENGTH_LONG).show(); 

filePath = data.getData(); 

try { 
      bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), filePath); 
      imageView.setImageBitmap(bitmap); 

      areaLeyendaImagen.setVisibility(View.VISIBLE); 
      areaFotoCargada.setVisibility(View.VISIBLE); 
      imagencargada.setVisibility(View.VISIBLE); 
      textoimagencargada.setVisibility(View.VISIBLE); 
      area_cerrarIagen.setVisibility(View.VISIBLE); 
      cerrarImagen.setVisibility(View.VISIBLE); 

      areaLeyendaImagen.setFocusableInTouchMode(true); 
      areaLeyendaImagen.requestFocus(); 
      areaLeyendaImagen.setFocusable(true); 
      buttonChoose.setError(null); 

     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

}else if (requestCode == PICK_IMAGE_REQUEST && resultCode == Activity.RESULT_OK) { 
     filePath = data.getData(); 
     try { 
      bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), filePath); 
      imageView.setImageBitmap(bitmap); 

      areaLeyendaImagen.setVisibility(View.VISIBLE); 
      areaFotoCargada.setVisibility(View.VISIBLE); 
      imagencargada.setVisibility(View.VISIBLE); 
      textoimagencargada.setVisibility(View.VISIBLE); 
      area_cerrarIagen.setVisibility(View.VISIBLE); 
      cerrarImagen.setVisibility(View.VISIBLE); 
      buttonChoose.setError(null); 

     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
} 

public String getPath(Uri uri) { 
    Cursor cursor = getActivity().getContentResolver().query(uri, null, null, null, null); 
    cursor.moveToFirst(); 
    String document_id = cursor.getString(0); 
    document_id = document_id.substring(document_id.lastIndexOf(":") + 1); 
    cursor.close(); 

    cursor = getActivity().getContentResolver().query(
      android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
      null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null); 
    cursor.moveToFirst(); 
    String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA)); 
    cursor.close(); 

    return path; 
}

UPDATE：

一旦畫面附着在ImageView的，我點擊一個按鈕，發送圖片，將其存儲在一個數據庫，我得到這個錯誤。

你在三星設備偶然測試它？ – Enzokie

是的，這是一個三星設備。 @Enzokie –

這是三星中的一個錯誤;）因此，假設getData在某個時刻爲空。 – Enzokie

我不知道你的代碼是做什麼的。但是，日誌說：應用程序已經崩潰，因爲空指針異常。

檢查ZygoteInit.java類的main方法。在1120行，您嘗試從null實例獲取某些內容。

你應該解決這個問題。

謝謝，我會檢查，並更新有關代碼的信息。 –

我認爲問題是在這裏,,這

bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), filePath);

改變這樣

Bitmap bitmap = (Bitmap) data.getExtras().get("data");

對不起，ImagePicker會是什麼，我得到'無法解析符號' –

我編輯了答案 –

我已經修改它，但它一直在崩潰。同一行 –

的這一翻譯你可以得到位圖當REQUEST_CAMERA

Bitmap thumbnail = (Bitmap) data.getExtras().get("data");

你可以得到位圖當PICK_IMAGE_REQUEST from gallery

Uri uri = data.getData(); 
    try { 
     Bitmap bitmap = MediaStore.Images.Media.getBitmap(mcontext.getContentResolver(), uri); 
       // Log.d(TAG, String.valueOf(bitmap)); 
    } catch (Exception e) { 
        e.printStackTrace(); 
    }

試試這個

values = new ContentValues(); 
values.put(MediaStore.Images.Media.TITLE, "New Picture"); 
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera"); 
imageUri = getContentResolver().insert(
    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); 
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); 
startActivityForResult(intent, CAMERA_CLICK_RESULT);

和onActivityResult

if (requestCode == CAMERA_CLICK_RESULT && resultCode == RESULT_OK) { 
     Bitmap photo = null; 
     try { 
      photo = MediaStore.Images.Media.getBitmap(
        getContentResolver(), imageUri); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    }
