如何在Android中的片段中創建是/否警報對話框

Question

這是我評論我需要的代碼。我嘗試了一些代碼，但它似乎與Fragment不兼容。

public class main extends Fragment { 

    ImageButton imagebutton; 

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     View rootView = inflater.inflate(R.layout.main, container, false); 

     imagebutton = (ImageButton) rootView.findViewById(R.id.im); 

     imagebutton.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       //Open Yes/No Dialog 

       //if Yes do something 
      } 
     }); 

    } 
}

試試這個方法：

private void createAndShowAlertDialog() { 
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
    builder.setTitle("My Title"); 
    builder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
       //TODO 
       dialog.dismiss(); 
     } 
    }); 
    builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
       //TODO 
       dialog.dismiss(); 
     } 
    }); 
    AlertDialog dialog = builder.create(); 
    dialog.show(); 
    } 

Answer 2

class MyDialogFragment extends DialogFragment{ 
    Context mContext; 
public MyDialogFragment() { 
    mContext = getActivity(); 
} 
@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 
    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(mContext); 
    alertDialogBuilder.setTitle("Really?"); 
    alertDialogBuilder.setMessage("Are you sure?"); 
    alertDialogBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() { 

     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      Toast.makeText(getApplicationContext(), "CLick-Click!!",Toast.LENGTH_LONG).show(); 
     } 
    }); 

    alertDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 

     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      dialog.dismiss(); 
     } 
    }); 


    return alertDialogBuilder.create(); 
} 
} 

創建對話框電話：

new MyDialogFragment().show(getFragmentManager(), "MyDialog");

，並從某處關閉該對話框： ((MyDialogFragment)getFragmentManager().findFragmentByTag("MyDialog")).getDialog().dismiss();

OR
嘗試使用這個片段：

AlertDialog.Builder mDialog = new AlertDialog.Builder(MyClassNane.this); 
mDialog.setTitle("Title"); 
mDialog.setMessage("Do you want to delete ?"); 
mDialog.setPositiveButton("Yes",new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog,int which) { 
        Toast.makeText(getApplicationContext(), 
        "Click-Click!!",Toast.LENGTH_LONG).show(); 
       } 
       dialog.cancel(); 
      } 
     }); 

mDialog.setNegativeButton("No", 
     new DialogInterface.OnClickListener() { 

      public void onClick(DialogInterface dialog, 
        int which) { 
       dialog.cancel(); 
      } 
     }); 
AlertDialog alert = mDialog.create(); 
alert.show();
