AlertDialog에서 무작위 충돌이 발생했습니다.

Question

Android 애플리케이션에 이상한 점이 있습니다. 두 개의 EditText 컨트롤과 일부 버튼 (기존 객체 편집)을 사용하여 AlertDialog을 만듭니다. 내가 텍스트 필드를 편집 할 수 초점을 변경하거나가 someting를 넣어하려고하면

@Override 
public void onClick(View arg0) { 
    AlertDialog.Builder alert = new AlertDialog.Builder(mContext); 

    final View dialogLayout = mInflater.inflate(R.layout.event_edit, null); 
    alert.setView(dialogLayout); 

    ((EditText)dialogLayout.findViewById(R.id.txtCompany)).setText(cEvent.getCompany()); 
    ((EditText)dialogLayout.findViewById(R.id.txtCity)).setText(cEvent.getCity()); 

    alert.setTitle(R.string.DialogEditEventTitle); 
    alert.setPositiveButton(R.string.DialogEditEventDelete, 
      new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      // Delete action 
     } 
    }); 

    alert.setNeutralButton(R.string.DialogEditEventSave, 
      new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      // Save 
     } 
    }); 

    alert.setNegativeButton(R.string.DialogEditEventCancel, 
      new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      // Cancel action 
     } 
    }); 
    AlertDialog dialog = alert.show(); 
    dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE); 

} 

, 그때 얻을 예외 :

무엇이 예외의 원인이며 어떻게 그것을 해결하기 위해 시도 할 수 있습니다?

Answer 1

시도해보십시오.

//first create, set soft input mode and then show// 

AlertDialog dialog = alert.create();  
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE); 
dialog.show();
