사진 또는 카메라 브라우저

Question

다음을 시도하고 있습니다. ImageView가 있는데 사진을 선택하거나 찍을 때 이미지 브라우저 나 카메라가 나타나기를 원합니다. 나는 것으로 나타났습니다 :

private void openPictureBrowser() 
{ 
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
    intent.setType("image/*"); 
    intent.putExtra(Intent.EXTRA_TITLE,"A Custom Title"); //optional 
    intent.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS); //optional 
    try { 
     startActivityForResult(intent, 1); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data){ 
    switch (requestCode) { 
     case 1: { 
     if (resultCode == RESULT_OK && data != null && data.getData() != null) { 
      String filePath = data.getData().getPath(); //WARNING: this is NOT your real path (in my case, value is set to "/external/images/media/4" 
     } 
     } 
    } 
} 

내가 카메라를 추가하려면 내가 openPictureBrowser에서 무엇을 할 수 있습니까?

그리고 FileView를 ImageView 배경으로 설정하려면 어떻게해야합니까?

아무도 나에게 힌트를 줄 수 있습니까 ??

Thanxs!
