如何創建自定義警報diaogue

Question

這是代碼谷歌表示，用來創建自定義提醒對話（它說，創建自己的佈局，然後使用該佈局的setContentView）

@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
// Get the layout inflater 
LayoutInflater inflater = getActivity().getLayoutInflater(); 

// Inflate and set the layout for the dialog 
// Pass null as the parent view because its going in the dialog layout 
builder.setView(inflater.inflate(R.layout.dialog_signin, null)) 
// Add action buttons 
     .setPositiveButton(R.string.signin, new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface dialog, int id) { 
       // sign in the user ... 
      } 
     }) 
     .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int id) { 
       LoginDialogFragment.this.getDialog().cancel(); 
      } 
     });  
return builder.create(); 
} 

谷歌則表示，以在另一個類中創建此類的實例，然後使用show（）方法顯示它，但是show方法需要一個片段管理器，並且片段管理器在嘗試創建它時會收到錯誤。

，我需要一個微調添加到啓動一個新的活動

警報對話如果有人能想出如何得到這個工作（使對話彈出）並張貼這將是巨大

Answer 1

您可以創建Alert Dialog with spinner這樣

更新

public class WvActivity extends Activity { 

TextView tx; 
String[] s = { "India ", "Arica", "India ", "Arica", "India ", "Arica", 
    "India ", "Arica", "India ", "Arica" }; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.main); 

final ArrayAdapter<String> adp = new ArrayAdapter<String>(WvActivity.this, 
     android.R.layout.simple_spinner_item, s); 

tx= (TextView)findViewById(R.id.txt1); 
final Spinner sp = new Spinner(WvActivity.this); 
sp.setLayoutParams(new  LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT)); 
sp.setAdapter(adp); 

AlertDialog.Builder builder = new AlertDialog.Builder(WvActivity.this); 
builder.setView(sp); 
builder.create().show(); 
} 
}
