Question

我想为日语应用程序制作一个分享按钮。在此共享按钮上，我想让用户能够打开任何应用程序即。 whatsapp，Line，Hetache，fb，tweeter以及用户设备中的任何共享应用程序。有可能吗？

Answer 1

尝试使用隐式意图的发送操作，并允许选择从设备共享应用。

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));

    getMenuInflater().inflate(R.menu.main, menu);
    MenuItem menuItem = menu.findItem(R.id.action_share);
    actionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);  
    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("text/plain");
    intent.putExtra(Intent.EXTRA_TEXT, "ActionBarCompat is Awesome! Support Lib v7 #Xamarin");
    actionProvider.setShareIntent (intent);
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub

    switch (item.getItemId()) {
    case R.id.action_edit:
        Toast.makeText(getApplicationContext(), "Editing", Toast.LENGTH_LONG).show();
        break;

    default:
        break;
    }
    return super.onOptionsItemSelected(item);
}
}
