Java 使用现有xml小部件的Alertdialog setView（）

我在.xml文件中有一个带有LinearLayout的EditText，希望将其添加为AlertDialog上的

setView（）

参数。这可能吗？以下是我尝试过的：

AlertDialog.Builder builder = new AlertDialog.Builder(this);
final EditText input = new EditText(this);
builder.setView(input);

但启动时对话框为空。我做错了什么？

像这样使用它

AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.your_layout, null);
builder.setView(dialogView);

AlertDialog alertDialog = builder.create();
alertDialog.show();

EditText editText = (EditText) dialogView.findViewById(R.id.your_edit_text);

使用

dialogView

可以像这样获得您的

EditText

AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.your_layout, null);
builder.setView(dialogView);

AlertDialog alertDialog = builder.create();
alertDialog.show();

EditText editText = (EditText) dialogView.findViewById(R.id.your_edit_text);

也许会有帮助

 AlertDialog.Builder builder = new AlertDialog.Builder(this);
   LayoutInflater inflater = getLayoutInflater();
builder.setView(inflater.inflate(R.layout.YourLayout, null));
AlertDialog ad = builder.create();
