如何使用微調器進行警告對話框

Question

我知道如何進行警告對話框，但我需要用微調器創建一個對話框，以便在彈出時人員可以選擇發生什麼。有沒有人有一個微調的警告對話框的代碼或知道任何好的教程？

在此先感謝

Answer 1

LayoutInflater li = LayoutInflater.from(context); 

View promptsView = li.inflate(R.layout.my_dialog_layout, null); 

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context); 

alertDialogBuilder.setView(promptsView); 

// set dialog message 

alertDialogBuilder.setTitle("My Dialog.."); 
alertDialogBuilder.setIcon(R.drawable.ic_launcher); 
// create alert dialog 
final AlertDialog alertDialog = alertDialogBuilder.create(); 

final Spinner mSpinner= (Spinner) promptsView 
     .findViewById(R.id.mySpinner); 
final Button mButton = (Button) promptsView 
     .findViewById(R.id.myButton); 

// reference UI elements from my_dialog_layout in similar fashion 

mSpinner.setOnItemSelectedListener(new OnSpinnerItemClicked()); 

// show it 
alertDialog.show(); 
alertDialog.setCanceledOnTouchOutside(false); 

其中

my_dialog_layout是你包含了微調mySpinner

EDIT彈出佈局：

public class OnSpinnerItemClicked implements OnItemSelectedListener { 

     @Override 
     public void onItemSelected(AdapterView<?> parent, 
       View view, int pos, long id) { 
      Toast.makeText(parent.getContext(), "Clicked : " + 
        parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show(); 


     } 

     @Override 
     public void onNothingSelected(AdapterView parent) { 
      // Do nothing. 
     } 
    }
