在 Twitter 上共享图像和文本不起作用

Question

这是我在下面给出的代码。FrameLayout 用于在 twitter 上共享为 JPEG 图像。这是我正在尝试的代码。

sharesp=(Spinner)findViewById(R.id.spnrShare);
        sharesp.setAdapter(new MyShAdapter(MainActivity.this, R.layout.rowview, Sharestring));
        sharesp.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> parent, View v,
                    int position, long arg3) {
                // TODO Auto-generated method stub
                selectitem=parent.getItemAtPosition(position).toString();
                selecetint=position;

                if(selectitem=="FaceBook" || selecetint==R.drawable.fbbtn){
                       shareFbook();

                }
                else if(selectitem=="Twitter" || selecetint==R.drawable.twitbtn){
                    shareTwitter();

                }
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });


public void shareTwitter(){

         FrameLayout savFrame_layout=(FrameLayout)findViewById(R.id.frame);
        try {
            if(MainActivity.this.mainFrame_layout==null){
            MainActivity.this.mainFrame_layout.setDrawingCacheEnabled(true);
              MainActivity.this.mainFrame_layout.refreshDrawableState();
              MainActivity.this.mainFrame_layout.buildDrawingCache();

            MainActivity.this.bm_ImgFrame = mainFrame_layout.getDrawingCache();

        int i1=100000;
        Random random=new Random();
        i1=random.nextInt(i1);
           MainActivity.fname = "Quick_"+ i1 + ".jpg";

            String pathy=Environment.getExternalStorageDirectory()+File.separator+"/MYAnApps";
            MainActivity.this.rootFile=new File(pathy);

            MainActivity.this.sdImageMainDirectory = new File(MainActivity.this.rootFile + MainActivity.fname);
            FileOutputStream fileOutputStream = new FileOutputStream(MainActivity.this.sdImageMainDirectory);
            bm_ImgFrame.compress(CompressFormat.JPEG, 80, fileOutputStream);

            Uri uri = Uri.parse(MainActivity.this.sdImageMainDirectory.getAbsolutePath());

                Intent intent = new Intent(Intent.ACTION_SEND);
                intent.setType("/*");
                intent.setClassName("com.twitter.android", "com.twitter.android.PostActivity");
                intent.putExtra(Intent.EXTRA_TEXT, "MyAndroidApp: https://play.google.com/store/apps/details?id=com.example.MyApp");
                intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(MainActivity.this.sdImageMainDirectory));
                startActivity(intent);            
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   

    }

Answer 1

尝试使用"*/*" 作为 MIME，这样您就可以发送任何通用数据类型。

 intent.setType("*/*");

还可以尝试将ACTION_SEND 更改为专门用于传递多个数据的ACTION_SEND_MULTIPLE。

有关ACTION_SEND_MULTPLE 和处理 MIME 类型的更多信息。

检查这个例子这对我有用

Twitter Image And text sharing Example

用这个分享推特

  private void showTwittDialog() {

    final Dialog dialog = new Dialog(getApplicationContext());
    dialog.setContentView(R.layout.twitt_dialog);
    dialog.setTitle("Twitter");

    Button btnPost = (Button) dialog.findViewById(R.id.btnpost);
    final EditText et = (EditText) dialog.findViewById(R.id.twittext);
    et.setText(sharingStr);
    et.setSelection(et.getText().length());
    btnPost.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
              twitt_msg = et.getText().toString().trim();   
            if (twitt_msg.length() == 0) {
                showToast("Tweet is empty!!!");
                return;
            } else if (twitt_msg.length() > 140) {
                showToast("Tweet of more than 140 characters not allowed!!!");
                return;
            }
            dialog.dismiss();
            new PostTwittTask().execute(twitt_msg);

    dialog.show();

    if (twitter_dialog != null  && twitter_dialog.startsWith("com.twitter.android")) {
        // if the native twitter app is found
        tweetIntent.setPackage(twitter_dialog);
        startActivity(tweetIntent);
    } else {
        showTwittDialog();
    }
    mTwitter.resetAccessToken();        
}

class PostTwittTask extends AsyncTask<String, Void, String> {
