嘿，我刚好遇到过类似的问题！Facebook对原生ACTION_SEND Intent的处理有不少限制，其中就包括不会解析EXTRA_TEXT里的话题标签，而且直接用原生分享会绕过你集成的SDK功能。别担心，下面给你一套完整的解决方案，帮你实现带话题标签的图片+文本分享：

核心思路 #

我们需要拦截IntentChooser中的Facebook选项，替换为Facebook SDK的ShareDialog来处理分享——这是官方支持添加话题标签的唯一方式，同时保留其他应用的原生分享逻辑。

步骤1：修改分享方法，拦截Facebook选项 #

先调整你的doSocialShare方法，先查询所有支持分享的应用，把Facebook的选项替换为触发SDK分享的自定义Intent：

public void doSocialShare(String title, String text, Bitmap resource) {
    // 1. 构建基础原生分享Intent（给非Facebook应用使用）
    Intent baseSendIntent = new Intent(android.content.Intent.ACTION_SEND);
    baseSendIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    baseSendIntent.putExtra(Intent.EXTRA_TEXT, text);
    baseSendIntent.putExtra(Intent.EXTRA_STREAM, getBitmapFromDrawable(resource));
    baseSendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    baseSendIntent.setType("image/*");

    // 2. 筛选所有支持分享的应用，单独处理Facebook
    PackageManager pm = getPackageManager();
    List<ResolveInfo> resolveInfos = pm.queryIntentActivities(baseSendIntent, 0);
    List<Intent> targetIntents = new ArrayList<>();

    for (ResolveInfo info : resolveInfos) {
        String packageName = info.activityInfo.packageName;
        Intent targetIntent = new Intent(baseSendIntent);

        // 识别Facebook主应用（包名通常为com.facebook.katana）
        if ("com.facebook.katana".equals(packageName)) {
            // 创建自定义Intent，跳转到我们的SDK分享处理页面
            targetIntent = new Intent(this, FacebookShareHandlerActivity.class);
            targetIntent.putExtra("share_text", text);
            // 注意：Bitmap不能直接跨Intent传递，先保存为本地文件再传路径
            String imagePath = saveBitmapToLocal(resource);
            targetIntent.putExtra("image_path", imagePath);
            targetIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        }

        targetIntent.setComponent(new ComponentName(packageName, info.activityInfo.name));
        targetIntents.add(targetIntent);
    }

    // 3. 构建最终的IntentChooser
    Intent chooserIntent = Intent.createChooser(targetIntents.remove(0), "Share via...");
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetIntents.toArray(new Parcelable[]{}));

    // 保留Android 5.1+的选择回调逻辑
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP_MR1) {
        Log.d("INFORMATION", "The current android version allow us to know what app is chosen by the user.");
        Intent receiverIntent = new Intent(this, ShareBroadcastReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, receiverIntent, PendingIntent.FLAG_CANCEL_CURRENT);
        chooserIntent = Intent.createChooser(chooserIntent, "Share via...", pendingIntent.getIntentSender());
    }

    startActivity(chooserIntent);
}

// 辅助方法：将Bitmap保存到本地文件，返回路径
private String saveBitmapToLocal(Bitmap bitmap) {
    File picsDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File shareImage = new File(picsDir, "share_" + System.currentTimeMillis() + ".png");
    try (FileOutputStream fos = new FileOutputStream(shareImage)) {
        bitmap.compress(Bitmap.CompressFormat.PNG, 90, fos);
        return shareImage.getAbsolutePath();
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

步骤2：用Facebook SDK实现带话题的分享 #

创建一个专门处理Facebook分享的FacebookShareHandlerActivity，用官方ShareDialog添加话题标签：

public class FacebookShareHandlerActivity extends AppCompatActivity {
    private CallbackManager callbackManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // 初始化Facebook SDK回调
        callbackManager = CallbackManager.Factory.create();

        String shareText = getIntent().getStringExtra("share_text");
        String imagePath = getIntent().getStringExtra("image_path");
        if (imagePath == null) {
            Toast.makeText(this, "图片加载失败", Toast.LENGTH_SHORT).show();
            finish();
            return;
        }

        // 构建分享图片
        SharePhoto sharePhoto = new SharePhoto.Builder()
                .setImageUrl(Uri.fromFile(new File(imagePath)))
                .setCaption(shareText)
                .build();

        // 添加话题标签（可以从shareText中解析，或者直接指定）
        ShareHashtag hashtag = new ShareHashtag.Builder()
                .setHashtag("#YourCustomHashtag")
                .build();

        // 组装分享内容
        SharePhotoContent shareContent = new SharePhotoContent.Builder()
                .addPhoto(sharePhoto)
                .setShareHashtag(hashtag)
                .build();

        // 显示分享对话框
        ShareDialog shareDialog = new ShareDialog(this);
        shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
            @Override
            public void onSuccess(Sharer.Result result) {
                Toast.makeText(FacebookShareHandlerActivity.this, "分享成功", Toast.LENGTH_SHORT).show();
                finish();
            }

            @Override
            public void onCancel() {
                finish();
            }

            @Override
            public void onError(FacebookException error) {
                Toast.makeText(FacebookShareHandlerActivity.this, "分享失败：" + error.getMessage(), Toast.LENGTH_SHORT).show();
                finish();
            }
        });

        if (ShareDialog.canShow(SharePhotoContent.class)) {
            shareDialog.show(shareContent);
        } else {
            Toast.makeText(this, "当前Facebook版本不支持图片分享", Toast.LENGTH_SHORT).show();
            finish();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }
}

记得在AndroidManifest.xml中注册这个透明主题的Activity：

<activity android:name=".FacebookShareHandlerActivity"
          android:theme="@android:style/Theme.Translucent.NoTitleBar"
          android:exported="false"/>

步骤3：调整Broadcast Receiver逻辑 #

现在用户选择Facebook时会走SDK分享，所以在Broadcast Receiver里可以过滤掉Facebook的回调，只处理其他应用：

public class ShareBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();
        if (extras == null) return;

        for (String key : extras.keySet()) {
            Object value = extras.get(key);
            Log.d(getClass().getSimpleName(), "Key: " + key + ", Value: " + value);
            
            // 跳过Facebook的回调，因为我们已经用SDK处理了
            if (value != null && value.toString().contains("com.facebook.katana")) {
                return;
            }
        }

        // 处理其他应用的分享回调逻辑
        // ...
    }
}

补充说明 #

1. 确保你已经正确初始化Facebook SDK（在Application类中调用FacebookSdk.sdkInitialize(getApplicationContext())）
2. Facebook Lite的包名是com.facebook.lite，如果需要支持可以在步骤1的包名判断中加上
3. 话题标签必须以#开头，ShareHashtag会自动处理格式
