andriod Inflater /查看異常

我想添加一個佈局（profile_upload）到我的自定義AlertDialog裏面的Profile.java 第一次工作正常。但是當我關閉AlertDialog並再次單擊按鈕時它崩潰sayng java.lang.IllegalStateException：指定的子項已經有父項。你必須對孩子的父母打電話removeView（）第一 Profile.javaandriod Inflater /查看異常

顯示「activity_profile.xml」的內容？ – t0mm13b

在此

removeall過意見，它會調用當u按導航後退按鈕

Tanq這麼多。它的工作很好現在.. – mahendra

做我的回答幫助你或你想你自己？ –

是的，我遵循你的建議。再一次感謝你。 – mahendra

或者，您也可以通過AlertDialog.Builder.create保存AlertDialog實例（），而不是AlertDialog.Builder實例。
如果使用自定義視圖，則會創建對話框，然後每次AlertDialog.Builder.show（）時都會將自定義視圖附加到對話窗口。

public class Profile extends AppCompatActivity implements View.OnClickListener { 
    AlertDialog dialog; 
    ImageButton profile_btn; 
    TextView tx_img_name; 
    Button btn_prfil_upld, btn_pic_choose; 
    ImageView img_prfl; 
    View v; 
    LayoutInflater inflater; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_profile); 

     profile_btn = (ImageButton) findViewById(R.id.user_profile_photo); 
     profile_btn.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       if(dialog == null) { 
        dialog = getBuilder().create(); 
       } 
       dialog.setTitle("Update Profile Picture"); 
       dialog.show(); 

      } 
     }); 
    } 

    @NonNull 
    private AlertDialog.Builder getBuilder() { 
     AlertDialog.Builder alert = new AlertDialog.Builder(this); 
     inflater = Profile.this.getLayoutInflater(); 
     if (v == null) { 
      v = inflater.inflate(R.layout.profile_upload, null, false); 
     } else { 
      ((ViewGroup) v.getParent()).removeView(v); 
     } 
     alert.setView(v); 


     btn_prfil_upld = (Button) v.findViewById(R.id.btnUpload_profile_pic); 
     btn_pic_choose = (Button) v.findViewById(R.id.btn_choose_profile_pic); 
     img_prfl = (ImageView) v.findViewById(R.id.img_profile_upload); 
     tx_img_name = (TextView) v.findViewById(R.id.tx_img_name); 
     btn_prfil_upld.setOnClickListener(this); 
     btn_pic_choose.setOnClickListener(this); 
     return alert; 
    } 

    public void onClick(View view) { 
     int id = view.getId(); 
     switch (id) { 
      case R.id.btn_choose_profile_pic: 
       break; 
      case R.id.btnUpload_profile_pic: 
       break; 
     } 
    } 
}

對不起，你能否請詳細解釋AlertDialog，AlertDialog.builder，Dialog。 – mahendra

或一個鏈接會做。我搜索了一下，但沒有找到滿意的答案。 – mahendra

我修改了部分代碼。我希望它給你一個幫助。 –
