Question

我有一个警报对话框，当我按下按钮以显示我选择的内容时，它什么也没有显示，只有黑色的褪色屏幕必须显示出来。

有我的代码：

final AlertDialog.Builder raspunsgresit = new AlertDialog.Builder(Intrebarea644.this);
LayoutInflater factory = LayoutInflater.from(Intrebarea644.this);
final View view = factory.inflate(R.layout.raspuns644, null);
raspunsgresit.setView(view);
if(view.getParent()!=null)
   ((ViewGroup)view.getParent()).removeView(view);
raspunsgresit.setPositiveButton("", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dlg, int sumthin) {
            }
    });

Answer 1

它只是AlertDialog.Builder。您需要先create() AlertDialog，然后show()。因此，您的代码将如下所示：

final AlertDialog.Builder raspunsgresit = new AlertDialog.Builder(Intrebarea644.this);
LayoutInflater factory = LayoutInflater.from(Intrebarea644.this);
final View view = factory.inflate(R.layout.raspuns644, null);
raspunsgresit.setView(view);
if(view.getParent()!=null)
 ((ViewGroup)view.getParent()).removeView(view);
raspunsgresit.setPositiveButton("", new DialogInterface.OnClickListener(){
 public void onClick(DialogInterface dlg, int sumthin){
 }
});
raspunsgresit.create().show();

警报对话框不显示任何内容
