StartActivityForResult实现确认对话框

1.

llDelete.setOnClickListener(new OnClickListener() {
			
			public void onClick(View v) {

				//删除弹出对话框
				showDeleteDialog();
			}
		});


/**
	 * 提示一个确认删除的对话框
	 * */
	public void showDeleteDialog()
	{
		Intent intent = new Intent();
		intent.setClass(ItemLongClickedActivity.this, DialogActivityOfComfirmDelete.class);//提示是否保存的Activity
		startActivityForResult(intent, REQUEST_CODE);
	}


private int REQUEST_CODE = 0; 
	private final int COMFIRM_DELETE = 5;
	private final int COMFIRM_NO_DELETE = 6;
	@Override  
    public void onActivityResult(int requestCode, int resultCode, Intent data)  
    {  
         super.onActivityResult(requestCode, resultCode, data);    
         
         if(requestCode == REQUEST_CODE)
         {
        	 if(resultCode == COMFIRM_DELETE)//保存当前联系人
    	     {
    	    	 System.out.println("执行删除联系人的操作");
    	    	 
    	    	 
    	     }
    	     if(resultCode == COMFIRM_NO_DELETE)//不保存
    	     {
    	    	 System.out.println("不删除联系人");
    	    	 
    	     }
         }
	     
    }
