添加自定義佈局空引用錯誤的警告對話框

-1

// Biuld the dialog 
AlertDialog.Builder alert = new AlertDialog.Builder(this); 

// Create the dialog 
AlertDialog alertToShow = alert.create(); 

// Set keyboard to the dialog 
alertToShow.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE); 

// Add custom layout to the dialog 
LayoutInflater inflater = this.getLayoutInflater(); 
View dialogView = inflater.inflate(R.layout.dialog_view, null); 
alert.setView(dialogView); 

// Show the dialog 
alertToShow.show();

但是從上面，我加我的自定義佈局

f1.addView(inflater.inflate(R.layout.dialog_view, f1, false));

導致錯誤的下面一行

嘗試在空對象引用上調用虛擬方法'void android.widget.FrameLayout.addView（android.view.View）'

任何想法如何解決錯誤？

您需要在顯示對話框或佈局膨脹後找到視圖。在此之前

// Add custom layout to the dialog 
LayoutInflater inflater = getLayoutInflater(); 
View dialogView = inflater.inflate(R.layout.dialog_view, f1, false) 
FrameLayout f1 = (FrameLayout) dialogView.findViewById(android.R.id.custom); 
f1.addView(dialogView); 

// Show the dialog 
alertToShow.show();

不過，我想你想alertToShow.setView(dialogView)，也許

我有我創建對話框

// Add custom layout to the dialog 
    LayoutInflater inflater = this.getLayoutInflater(); 
    View dialogView = inflater.inflate(R.layout.dialog_view, null); 
    alert.setView(dialogView); 

    // Create the dialog 
    AlertDialog alertToShow = alert.create(); 

    // Set keyboard to the dialog 
    alertToShow.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE); 

    // Show the dialog 
    alertToShow.show();

前加意見
