如何在AlertDialog显示后显示软键盘

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Dialog Title");
builder.setMessage("Dialog Message");

// 创建AlertDialog对象
AlertDialog alertDialog = builder.create();

// 显示AlertDialog
alertDialog.show();

// 获取AlertDialog的Window对象
Window window = alertDialog.getWindow();

// 设置Window的软键盘模式为可见状态
window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

// 获取AlertDialog中的EditText控件，并请求焦点
EditText editText = alertDialog.findViewById(R.id.editText);
editText.requestFocus();
