如何在导航抽屉中显示 google 加头像？

Question

下面的代码来自 github android 通过 gmail 登录 app.I 做了一些修改以使用 volley 显示个人资料图片。它工作正常。我只想在导航抽屉中显示这些东西。

个人资料照片、姓名和电子邮件 ID。

我使用了 android 工作室中的导航抽屉 activity。我只是尝试使用 bundle 将这些东西发送到另一个 activity 但失败了。

        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);

在接收方

   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);

如有帮助将不胜感激

Answer 1

我会使用 Glide 或 Picasso 加载图像 URL，而不是传递位图。如果您确实需要本地位图，那么您可以写入磁盘并将图像的 URI 传递给下一个 Activity，而不是传递位图。

所以此时：

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 "a person" 关于使用 Piccaso or Glide。

你可以参考我下面使用Piccaso的代码：

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);
        }
    }
