Question

以下代码来自github，在android app中通过gmail登录。我做了一些修改，用volley显示个人资料图片。它的工作正常。我只是想在导航抽屉里展示这些东西。

个人资料图片，姓名和电子邮件ID。

我使用了android studio中的导航抽屉活动。我只是尝试使用bundle发送这些东西发送给另一个活动但是失败了。

        Drawable drawable=profilePhoto.getDrawable();
        Bitmap bitmap= ((BitmapDrawable)drawable).getBitmap();
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
        byte[] b = baos.toByteArray();
        Intent intent3=new Intent(this,MainActivity.class);
        intent3.putExtra("picture", b);
        startActivity(intent3);

和接收方

   Bundle extras = getIntent().getExtras();
    byte[] b = extras.getByteArray("picture");
    Bitmap bmp = BitmapFactory.decodeByteArray(b, 0,100);
    ImageView image = (ImageView) findViewById(R.id.profilePhoto);
    image.setImageBitmap(bmp);

Answer 1

我会使用Glide或Picasso加载图片网址，而不是传递Bitmap。如果你想在本地使用Bitmap，那么你可以写入磁盘并将图像的URI传递给下一个Activity，而不是传递Bitmap。

所以在这一点上：

Drawable drawable=profilePhoto.getDrawable();
Bitmap bitmap= ((BitmapDrawable)drawable).getBitmap();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();

..创建byte []后，您可以将其写入磁盘，然后将URI传递给下一个Activity。如果您尚未使用它，则需要在您的清单中获得许可。

Answer 2

我同意 ＆＃34;一个人＆＃34; 关于使用Piccaso或Glide。

您可以使用Piccaso参考我的以下代码：

private void handleSignInResult(GoogleSignInResult result) {
        Log.d(TAG, "handleSignInResult:" + result.isSuccess());
        if (result.isSuccess()) {
            // Signed in successfully, show authenticated UI.
            GoogleSignInAccount acct = result.getSignInAccount();
            mStatusTextView.setText(getString(R.string.signed_in_fmt, acct.getDisplayName()));
            // Views inside NavigationView's header
            mUserTextView.setText(acct.getDisplayName());
            mEmailTextView.setText(acct.getEmail());
            Uri uri = acct.getPhotoUrl();
            Picasso.with(mContext)
                    .load(uri)
                    .placeholder(android.R.drawable.sym_def_app_icon)
                    .error(android.R.drawable.sym_def_app_icon)
                    .into(mProfileImageView);
            updateUI(true);
        } else {
            // Signed out, show unauthenticated UI.
            updateUI(false);
        }
    }
