圖片或相機瀏覽器

我正在嘗試做下一個：我有一個ImageView，我希望它出現在圖片瀏覽器或相機，當用戶觸摸它，讓他選擇或拍照。我發現：圖片或相機瀏覽器

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" 
     } 
     } 
    } 
}

我可以做openPictureBrowser如果我想添加的攝像頭？

我應該怎麼做onActivityResult將filePath設置爲ImageView背景？

任何人都可以給我一個提示嗎？

Thanxs！

所以，你想讓用戶從圖庫或相機中選擇一個圖像，然後（顯然）在ImageView中顯示結果？ –

看看我的答案... –
