使用相機並在SD卡中存儲捕獲的結果在android

Question

我想要在應用程序中使用相機，因爲在圖像被捕獲後，我想將該圖像存儲在SDCard中並在屏幕中顯示該圖像。

誰能幫我...

感謝

Answer 1

使用ACTION_IMAGE_CAPTURE意圖發動攝像頭活動：

Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
startActivityForResult(intent, 0); 

這裏有一個詳細的例子：http://labs.makemachine.net/2010/03/simple-android-photo-capture/，我認爲適合你的問題，以捕獲圖像，存儲在SD卡，然後在ImageView中顯示圖像。

Enjoy !!!

您可以調用下面的方法系統相機使用：

private void startCameraActivity() { 
    File file = new File("/sdcard/test/test.jpg"); 
    Uri outputFileUri = Uri.fromFile(file); 
    Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 
    startActivityForResult(intent, REQUEST_CODE_CAMERA); 
} 

當調用完成後，你會得到的圖片使用onActivityResult：

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    Log.i("MakeMachine", "requestCode:"+requestCode + ",resultCode: " + resultCode); 
    switch(requestCode){ 
     case ModifyUserActivity.REQUEST_CODE_CAMERA: 
      switch (resultCode) { 
       case Activity.RESULT_CANCELED: 
        picFileName = null; 
        Log.i("MakeMachine", "User cancelled"); 
        break; 
       case Activity.RESULT_OK:     
        File file = new File("/sdcard/test/test.jpg"); 
        if(file.exists()){ 
         BitmapFactory.Options options = new BitmapFactory.Options(); 
         options.inSampleSize = 4; 
         Bitmap bitmap = BitmapFactory.decodeFile(picFileName, options); 
         imgTakePhoto.setImageBitmap(bitmap); 
         imgTakePhoto.setVisibility(View.VISIBLE); 
        } 
        break; 
       default: 
        break; 
      } 
      break; 
     default: 
      break; 
    } 

}
