次のコードを使用して、カメラまたはその他のインテントから画像を取得しています。Samsung S2 では正常に動作しますが、HTC でエラーが発生します
private void openImageIntent()
{
// Determine Uri of camera image to save.
final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "OpenionDroid" + File.separator);
root.mkdirs();
final String fname = UUID.randomUUID().toString();
final File sdImageMainDirectory = new File(root, fname);
outputFileUri = Uri.fromFile(sdImageMainDirectory);
// Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = mContext.getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for(ResolveInfo res : listCam)
{
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
cameraIntents.add(intent);
}
// Filesystem.
final Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[]{}));
startActivityForResult(chooserIntent, Constants.IMAGE_REQUEST_CODE);
}
@SuppressWarnings("static-access")
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if(resultCode == mContext.RESULT_OK)
{
if(requestCode == Constants.IMAGE_REQUEST_CODE)
{
final boolean isCamera;
if(data == null)
{
isCamera = true;
}
else
{
final String action = data.getAction();
if(action == null)
{
isCamera = false;
}
else
{
isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
}
}
Uri selectedImageUri;
if(isCamera)
selectedImageUri = outputFileUri;
else
selectedImageUri = data == null ? null : data.getData();
if (isPhoto1Selected)
{
photo1Uri = selectedImageUri;
try {
Bitmap bitmap = Utilities.decodeSampledBitmap(Utilities.readBytes(selectedImageUri, mContext), 100, 100);
myQuestion.setLeftThumbnail(Utilities.decodeBitmapToArray(bitmap));
photo1.setImageBitmap(bitmap);
} catch (IOException e) {
Utilities.displayAlert("Oops!", e.getMessage(), mContext);
e.printStackTrace();
}
}
else
{
photo2Uri = selectedImageUri;
try {
Bitmap bitmap = Utilities.decodeSampledBitmap(Utilities.readBytes(selectedImageUri, mContext), 100, 100)
;
myQuestion.setRightThumbnail(Utilities.decodeBitmapToArray(bitmap));
photo2.setImageBitmap(bitmap);
} catch (IOException e) {
Utilities.displayAlert("Oops!", e.getMessage(), mContext);
e.printStackTrace();
}
}
}
}
}
私のコードではS2がこれに入ります
if(data == null)
{
isCamera = true;
}
HTCがここに行く間
isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
結果 isCamera は false です。だからそれは実行しようとします
selectedImageUri = data == null ? null : data.getData();
nullを与える
どうすればカメラから画像を取得できますか?
