我想通过Facebook上的分享意图与我的应用程序预先填充的标题分享照片.

示例代码

Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/*");      

intent.putExtra(Intent.EXTRA_TEXT, "eample");
intent.putExtra(Intent.EXTRA_TITLE, "example");
intent.putExtra(Intent.EXTRA_SUBJECT, "example");
intent.putExtra(Intent.EXTRA_STREAM, imageUri);

Intent openInChooser = new Intent(intent);
openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
startActivity(openInChooser);

这是我得到的屏幕截图

如果设置类型为图像/*,则上传照片时不会预填充文本.如果设置为文本/普通照片不显示.....

        super.onCreate(savedInstanceState);
        setContentView(R.layout.a);
    final Button btnOpenPopup = (Button) findViewById(R.id.openpopup);
    btnOpenPopup.setOnClickListener(new Button.OnClickListener() {

        public void onClick(View arg0) {
            LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
                    .getSystemService(LAYOUT_INFLATER_SERVICE);
            View popupView = layoutInflater.inflate(R.layout.main, null);
            final PopupWindow popupWindow = new PopupWindow(popupView,
                    LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

            ListView listView = (ListView) popupView.findViewById(R.id.listView1); …
