解决方案
@ codeMagic接近，但完整的答案，从这个答案 cribbed，就是要做到这一点：
//创建AlertDialog
builder.setTitle（评估这啤酒）;
builder.setView（getLayoutInflater（）膨胀（R.layout.rate_stars，NULL））;
AlertDialog对话框= builder.create（）;//删除dialog.setContentView（R.layout.rate_stars）;
//删除dialog.setTitle（评估这啤酒）;
dialog.show（）;
希望这有助于！
I created a custom dialog with buttons, but when I go to launch it, my app force closes. I had the dialog working earlier without custom buttons. And am not sure where I am messing up here:
public class BeerPage extends ActionbarMenu {
BeerData e;
Dialog dialog = null;
AlertDialog.Builder builder;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.beer_page);
builder = new AlertDialog.Builder(this);
//get data from listview
Intent intent = getIntent();
Bundle b = intent.getExtras();
e = b.getParcelable("myBeerObject");
//test shared prefs
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
String userName = prefs.getString("userName", null);
String userID = prefs.getString("userID", null);
//set image
ImageView im1 = (ImageView) findViewById(R.id.image);
if(e.largeLabel.equals("N/A")){
//set image as png
im1.setImageResource( R.drawable.noimage);
}
else{
ImageDownloadTask imageD = new ImageDownloadTask(im1);
imageD.execute(e.largeLabel);
}
//check if user has beer
String url = "myURL";
String userURLComp = "u=" + userID;
String beerID = "&b=" + e.beerId;
url = url + userURLComp + beerID;
new CheckBeerJSON(this,e.beerId).execute(url);
String url2 = "myURL2";
new GetBeerRateJSON(this,e.beerId).execute(url2);
//inflate loder image
LayoutInflater mInflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout addButton = (LinearLayout)((Activity) this).findViewById(R.id.addBeerLayout);
addButton.addView(mInflater.inflate(R.layout.checkingportfolio, null));

//set text thinsg
tv1.setText(e.beerName);
tv2.setText(e.beerDescription);
String breweryButton = "Brewery: ";
String styleButton = "Style: ";
tv_breweryName.setText(e.beerBreweryName);

breweryButton = breweryButton + e.beerBreweryName;
styleButton = styleButton + e.beerStyle;
//buttonBrewery.setText(breweryButton);

解决方案
@codeMagic is close, but the full answer, cribbed from this answer, is to do this:
// Create the AlertDialog
builder.setTitle("Rate this Beer");
builder.setView(getLayoutInflater().inflate(R.layout.rate_stars, null));
AlertDialog dialog = builder.create();
// DELETE dialog.setContentView(R.layout.rate_stars);
// DELETE dialog.setTitle("Rate this Beer");
dialog.show();
Hope this helps!
