在我的應用程序,我必須讓用戶從相機拍照/從畫廊中選擇。 我的代碼在某些設備上工作正常,但是當我在Galaxy s4上運行並且通過攝像頭拍照時,該照片沒有顯示在imageView上(從畫廊中選擇 - 可以正常工作),問題是在Galaxy s4中通過攝像頭拍照時。 我在將圖片顯示在imageView之前縮放了圖片。 這裏是我的代碼拍照:當我拍照時,它不顯示在只有在銀河s4的imageView
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
這是起飛後的照片我的代碼:
if (requestCode == 1)
{
File f = new File(Environment.getExternalStorageDirectory().toString());
File image_file = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles())
{
if (temp.getName().equals("temp.jpg"))
{
f = temp;
break;
}
}
try
{
Bitmap bitmap;
//BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
//bitmap=decodeFile(f.getAbsolutePath());//Collapse image
//setImageOnBitmap(bitmap);//Set the image on the imageview
BitmapHandler b=new BitmapHandler(getApplicationContext());
bitmap=b.decodeFileAsPath(f.getAbsolutePath(),"camera");
setImageOnBitmap(bitmap);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Phoenix" + File.separator + "default";
f.delete();
}
catch (Exception e)
{
e.printStackTrace();
}
}
這是我的函數的圖像文件進行解碼:
public static Bitmap decodeSampledBitmapFromFile(String path, int reqWidth, int reqHeight)
{ // BEST QUALITY MATCH
//First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);
// Calculate inSampleSize, Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
options.inPreferredConfig = Bitmap.Config.RGB_565;
int inSampleSize = 1;
if (height > reqHeight)
{
inSampleSize = Math.round((float)height/(float)reqHeight);
}
int expectedWidth = width/inSampleSize;
if (expectedWidth > reqWidth)
{
//if(Math.round((float)width/(float)reqWidth) > inSampleSize) // If bigger SampSize..
inSampleSize = Math.round((float)width/(float)reqWidth);
}
options.inSampleSize = inSampleSize;
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(path, options);
}
有錯誤嗎? –
沒有。我檢查它,它只是不顯示圖像沒有錯誤 – Toda
