android showDialog(int what）（转）

android showDialog(int what)

利用onCreateDialog 显示对话框的方式

1.重写onCreateDialog（int id）

@Override
 protected Dialog onCreateDialog(int id) {
  Builder builder = null;
  switch (id) {
  case 1:
   builder = new AlertDialog.Builder(this)
          .setIcon(R.drawable.d_message)
          .setTitle("Message")
          .setMessage(R.string.runeEncrypt_message)
          .setNeutralButton("知道了", new DialogInterface.OnClickListener() {
          
          @Override
          public void onClick(DialogInterface dialog, int which) {
           // TODO Auto-generated method stub
           ShowView.back(RunEncoding.this);
          }
         });
   break;
  case 2:
   builder = new AlertDialog.Builder(RunEncoding.this)
    .setIcon(R.drawable.d_message)
   .setTitle("取消")
   .setMessage("您确实要取消吗")
   .setPositiveButton(R.string.positive, new DialogInterface.OnClickListener() {
    
    @Override
    public void onClick(DialogInterface dialog, int which) {
     // TODO Auto-generated method stub
     cancelFlag = false;
    }
   }).
   setNegativeButton(R.string.negative, new DialogInterface.OnClickListener() {
    
    @Override
    public void onClick(DialogInterface dialog, int which) {
     // TODO Auto-generated method stub
     
    }
   });
   break; 
  default:
   break;
  }
  return builder.create();
 }

2，调用显示对话框 showDialog（id）; 该方法会调用onCreateDialog方法来显示对话框
