在Android中創建自定義提醒對話框時出錯

Question

在Android應用程序中創建自定義Alert Dialog時，出現以下錯誤。

錯誤

requestFeature() must be called before adding content

以下是我的自定義Alert Dialog創建代碼。

碼

AlertDialog alertDialog=new AlertDialog.Builder(home.this).create();
alertDialog.setTitle("Title here..");
alertDialog.setContentView(R.layout.custom_alertdialog);
alertDialog.show(); 

Answer 1

自定義對話框的代碼段如下：

使用新的Dialog而不是DialogBu​​ilder

Dialog d = new Dialog(MainActivity.this);
        d.setContentView(R.layout.dialog);
        d.setTitle("This is custom dialog box");
        d.show();   

Answer 2

從第一行刪除.create（）。

Answer 3

以此為指導：

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                    YourActivity.this);

alertDialogBuilder.setTitle("Your title here...");

alertDialogBuilder
        .setMessage("Your message here...")
        .setCancelable(false)
        .setPositiveButton("Yes",new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog,int id) {
                // Your works
                }
            })
        .setNegativeButton("No",new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog,int id) {
                dialog.cancel();
            }
        });

AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.setContentView(R.layout.custom_alertdialog);
alertDialog.show();

嘗試這個 ：

AlertDialog.Builder alertDialogBuilder=new AlertDialog.Builder(home.this);
alertDialogBuilder.setTitle("Title here..");
alertDialogBuilder.setContentView(R.layout.custom_alertdialog);
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
