AlertDialog.Builder alert = new AlertDialog.Builder(this);

}

    // Canceled. 
  } 
}); 

alert.show(); 


    // TODO Auto-generated method stub
    return super.onCreateDialog(id);


}

Answer 1

试试这个：

return alert.create();

而不是：

alert.show(); 

// TODO Auto-generated method stub
return super.onCreateDialog(id);

Answer 2

protected Dialog onCreateDialog (int id, Bundle args)

不推荐使用此方法。使用新的DialogFragment类而是FragmentManager;这也适用于旧平台通过Android兼容包。回调创建活动管理（保存和恢复）的对话框。默认实现调用onCreateDialog（int）兼容性。如果您的目标是HONEYCOMB或更高版本，请考虑而是使用DialogFragment代替。

可能这段代码可以帮到你......

Builder pinBuilder = new AlertDialog.Builder(context);
    pinBuilder.setView(pinHolder).setTitle("Title")
        .setMessage("Set Message")
        .setPositiveButton("Ok", new DialogInterface.OnClickListener()
        {
            @Override
            public void onClick(DialogInterface dialog, int which) 
            {



            } 
    }).
    setNegativeButton("Cancel",new DialogInterface.OnClickListener()
    {        
            @Override
            public void onClick(DialogInterface dialog,int which) 
            {

            }
    }).show();

Answer 4

尝试alert.create().show();

报告，如果它不起作用。

Answer 5

可能这段代码可能对您有所帮助。首先创建扩展对话框的类，然后从您的活动中调用此

CustomizeDilogForAddPhoto customizeDialog = new CustomizeDilogForAddPhoto(conntext,activity);
                customizeDialog.show();

这是您的对话类

public class CustomizeDilogForAddPhoto extends Dialog implements OnClickListener 
{
    public CustomizeDilogForAddPhoto(Context context,Activity activity)
    {
        super(context);

        this.context=context;
        this.activity=activity;
        this.mainActivityname=maintabactivity;

        requestWindowFeature(Window.FEATURE_NO_TITLE);

        requestWindowFeature(android.R.style.Theme_Translucent_NoTitleBar);
        /** Design the dialog in main.xml file */
        setContentView(R.layout.custume_add_photo_dilog);

        btnClose.setOnClickListener(this);
        btnGallary.setOnClickListener(this);

    }   
    @Override
    public void onClick(View v) 
    {

    }
}

onCreateDialog方法中的异常？
