使用Twitter的ComposeActivity类

Question

我目前正在开发一种社交媒体应用程序，该应用程序具有编写推文并将其发布到Twitter的功能。我进行了一些研究，并在这里找到一个示例：https://github.com/twitter/twitter-kit-android/wiki/Compose-Tweets。调用postToTwitter时，Twitter活动开始，并且文本和图像显示在Twitter UI中，但是当我选择“ tweet”时，没有任何内容发布到Twitter。我已经完成了实现Twitter登录的步骤。我把我的课放在下面了。方法postToDB和postToFacebook与该问题无关，因此可以忽略。

public class CreatePost extends Activity {

private String TAG = "CreatePost";
private Button share;
private EditText description;
private Button pickImage;
private ImageView imageView;
private ProgressBar progressBar;
private CheckBox checkBoxButton;
private CheckBox twitterCheckBox;
private BottomNavigationView navigation;
private Bitmap bitmap = null;
private Post post;
private Uri uri;

private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener = new BottomNavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
        switch(menuItem.getItemId()){
            case R.id.navHome:
                Intent i = new Intent(CreatePost.this, MainActivity.class);
                startActivity(i);
                return true;
            case R.id.createPost:
                return true;
            case R.id.account:
                i = new Intent(CreatePost.this, AccountSettings.class);
                startActivity(i);
