Question

您好我正在尝试创建共享意图，可以在通过onOptionsItemSelected选择菜单共享按钮时调用。当我按下分享按钮时，它会调用onOptionsItemSelected但不提供共享选项。你能告诉我这里的错误吗？我有多种方法可以实现，但我想知道为什么这不起作用。

这是代码：

public boolean onCreateOptionsMenu(Menu menu) {
    /* Use AppCompatActivity's method getMenuInflater to get a handle on the menu inflater */
    MenuInflater inflater = getMenuInflater();
    /* Use the inflater's inflate method to inflate our menu layout to this menu */
    inflater.inflate(R.menu.detail, menu);
    /* Return true so that the menu is displayed in the Toolbar */
    //MenuItem menuItem = menu.findItem(R.id.action_share);
    //menuItem.setIntent(createShareForecastIntent());

    return true;
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    String message  = "Yes I am here";


    // TODO (2) Launch the map when the map menu item is clicked
    if( id == R.id.action_share) {
        Toast.makeText(this, message, Toast.LENGTH_LONG).show();

        item.setIntent(createShareForecastIntent());
        return true;
    }


    return super.onOptionsItemSelected(item);
}

private Intent createShareForecastIntent() {
    Intent shareIntent = ShareCompat.IntentBuilder.from(this)
            .setType("text/plain")
            .setText(mForecast + FORECAST_SHARE_HASHTAG)
            .getIntent();
    return shareIntent;
}

}

在您粘贴的代码段中，您忘记致电 -

set /A Count=0
for %%I in (*.txt) do set /A Count=%Count%+1
echo %Count%
